4.3/5
The Stream Ultra X is the most accomplished balcony storage system to date. Where most systems settle for a battery module wired to a hub, EcoFlow packs everything into one box: 3.84 kWh of LiFePO4 cells, a hybrid inverter, four MPPT controllers and even two AC outlets. In practice, you plug in your panels (up to 2000 W), store the day's surplus and release it in the evening, either fed back into the grid (800 W, within balcony limits) or straight to its outlets at up to 1200 W during an outage (2300 W of connected appliances while the grid is available). The IP65 housing and self-heating down to -4 °F (-20 °C) allow year-round outdoor installation, and the app control is thorough. Two reservations: at 39 kg, plan a solid mount and a two-person install, and its price places it firmly at the premium end of balcony solar. But for anyone who wants to maximise self-consumption without stacking boxes, it is a very convincing proposition.
Marstek Jupiter C Plus
$811.05 (9)
2560 Wh, 4 MPPT and 2400 W of solar input in DC coupling: Marstek's plug-and-play balcony battery expandable to 10240 Wh.
- Capacity: 2560 Wh (LiFePO4), expandable to 10240 Wh

3.6/5
The Jupiter C Plus shares its base capacity figure (2560 Wh) and several specs with Marstek's own Venus C, a separate AC-coupled model rather than this DC-coupled one: the two are easy to mix up, but they aren't the same unit. In practice, it's a serious balcony battery: its 4 MPPT trackers and 2400 W of solar input let you wire up to 4 panels without worrying much about partial shading, and the HD touchscreen makes initial setup far easier than a phone app alone. Several users report solid compatibility with Shelly Pro 3EM meters and Germany's Ecotracker, plus a responsive support team when the initial pairing gets stuck. Our main reservation concerns availability outside Germany: at the time of writing, there's still no official store or established retailer in France, Italy or Spain, which means going through a third-party Amazon seller at a noticeably higher price than in Germany. For anyone able to order directly from the manufacturer, the value for money remains among the best in the category.
Growatt NOAH 2000
$925.19 $450.44
(9)
2048 Wh, 2 MPPT and 1800 W of DC-coupled solar input: one of Europe's best-selling plug-and-play balcony batteries, expandable to 8192 Wh.
- Capacity: 2048 Wh (LiFePO4), expandable to 8192 Wh
- Solar: 2 MPPT, up to 1800 W input, 99% efficiency
- Coupling: DC, between panels and microinverter

- One of Europe's best-selling plug-and-play balcony batteries
The Growatt NOAH 2000 is a balcony solar storage battery in DC coupling, sitting between the panels and a microinverter rather than on the AC output. Its 2 MPPT controllers accept up to 1800 W of panels, with a stated 99% MPPT efficiency. Its 2048 Wh LiFePO4 battery is IP66 rated, with a built-in heating film for operation down to -4 °F (-20 °C), and extends up to 8192 Wh by stacking 4 modules. Plug-and-play installation, controlled over Wi-Fi and Bluetooth, backed by a 10-year warranty: it is one of the most established and best-selling balcony batteries on the European market.
In-depth reviewRead our full review →
3.6/5
The NOAH 2000 owes its popularity to a simple pitch: a reliable, well-built balcony battery, at a price that stays competitive thanks to frequent promotions. Its DC coupling (between the panels and a microinverter) rather than AC output is less common than with rivals, but works well once understood: it needs a compatible microinverter downstream, with Growatt offering its own NEO 800M-X for this purpose. The 2 MPPT controllers and the stated 99% conversion efficiency make the NOAH 2000 a technically solid choice, and the built-in heating film is a real plus in winter. Our main reservation concerns availability: at the time of writing, the product remains distributed primarily in Germany through specialised retailers, with still-limited presence in other European markets. For anyone with access to a reliable retailer, it is a safe bet in balcony storage.
EcoFlow Stream AC Pro
$1217.25 $946.45
(8)
1920 Wh and up to 2300 W of AC output: the plug-and-play expansion battery compatible with any microinverter on the market.
- Capacity: 1920 Wh (LiFePO4), expandable to 11.52 kWh
- Output: 1200 W (2 AC outlets), 2300 W with two units, 800 W to grid
- Compatibility: 100% of microinverters on the market
- All weather: IP65, self-heating battery down to -4 °F (-20 °C)
- Plug-and-play expansion battery, no MPPT or inverter to manage
The EcoFlow Stream AC Pro is the pure battery variant of the STREAM range, with no MPPT or built-in inverter, designed to add storage to a balcony solar setup that already has a microinverter in place. It connects purely over AC, making it compatible with virtually any microinverter on the market. Its 1920 Wh LiFePO4 battery exchanges up to 1200 W with the installation, with grid feed-in capped at 800 W. IP65 rated with a self-heating battery down to -4 °F (-20 °C), it is controlled through the EcoFlow app, with an AI assistant and off-peak tariff scheduling. Expandable to 11.52 kWh by pairing it with a Stream Ultra, Pro or Max.
The Stream AC Pro fills a real gap: a simple expansion battery, with no MPPT or built-in inverter, for anyone who already has a solar microinverter in place. It connects over AC, which makes it compatible with almost any existing setup, unlike systems that impose their own solar regulation. The 2300 W its outlets accept while the grid is available easily handle power-hungry appliances, and integration into the STREAM ecosystem (Ultra, Pro, Max) lets you build an installation that grows over time. Off-peak tariff scheduling and the app's AI assistant remain strong points shared across the whole range. Our one reservation: availability remains limited in some markets at the time of writing. For anyone wanting to add storage to an existing solar setup without complexity, this is a solid option.
Hoymiles HiBattery 1920 AC
$975.37 (8)
AC-coupled balcony battery, 1.92 kWh expandable to 11.52 kWh, works with any inverter you already own, 1000 W backup output, IP66, 10 year warranty.
- Capacity: 1.92 kWh (LiFePO4), expandable up to 11.52 kWh
- Compatibility: AC coupling, works with an inverter you already own
- Backup: 1000 W output, automatic switch in under 0.02 s
- Safety: IP66, BMS, 6000 cycles, 10 year warranty
- Adds to an existing solar setup, no need to replace it
The Hoymiles HiBattery 1920 AC is an AC-coupled solar storage battery, built to add storage to an existing balcony solar setup rather than replace it. Unlike an all-in-one system, it plugs in downstream of whatever micro-inverter you already own and stores the surplus through a dedicated electricity meter. Its 1.92 kWh capacity expands up to 11.52 kWh with five add-on modules, and a 1000 W backup output kicks in within 0.02 seconds during a power cut.
On paper, it's hard to guess that this grey box has no MPPT or inverter inside: the whole point of the HiBattery 1920 AC is to bolt onto a balcony solar setup you already have, sitting between the existing inverter and the wall socket. Setup comes down to two plugs, and the app finds the unit within minutes. To get the most out of the dynamic mode you'll want to pair it with a compatible meter, a Shelly 3EM does the job nicely, otherwise you're stuck setting a fixed charge power by hand, which works but is less refined. AC coupling has a real upside: self-consumption always comes first, only the surplus goes to the battery. On build quality, user reports mention a well finished case and solid connectors, and the backup output comes in handy during a power cut. With just over a hundred merchant reviews so far, Hoymiles is newer to storage than to micro-inverters, but early feedback is uniformly positive.

Its distinctive feature: beyond storing your panels' energy (dual MPPT, up to 1200W solar input), it can recharge from the grid (up to 800W) to store electricity during off-peak hours and release it at peak times. With 1600 Wh of LiFePO4 chemistry (6000 cycles, 10-year warranty), IP65 rating and a capacity expandable to 9.6 kWh via BP1600 add-on batteries, it is controlled over Bluetooth and Wi-Fi from the Anker app.
Jackery SolarVault 3 Pro
$1318.89 $832.56
(7)
2520 Wh, 4 MPPT and 4000 W of solar input, with a built-in 1200 W bidirectional inverter: Jackery's plug-and-play balcony battery, expandable to 15.12 kWh.
- Capacity: 2520 Wh (LiFePO4), expandable to 15.12 kWh
- Solar: 4 independent MPPT, up to 4000 W input
- Inverter: 1200 W bidirectional, built in, AC coupling available on top

The Jackery SolarVault 3 Pro is a balcony solar storage battery that packs its own 1200 W bidirectional inverter, unlike systems that require a separate microinverter. Its 4 independent MPPT controllers accept up to 4000 W of panels directly, and can be combined with an additional AC-coupling input to capture energy from an existing setup. Its 2520 Wh LiFePO4 battery is IP65 rated, with built-in heating, and extends up to 15.12 kWh by adding BP2500 expansion batteries. Plug-and-play installation, controlled through the Jackery app with AI-driven tariff optimisation, backed by a 10-year warranty.
The SolarVault 3 Pro sets itself apart with a built-in bidirectional inverter: unlike other DC-coupled balcony batteries that need a separate microinverter, this unit handles charging and 1200 W AC output on its own. Its 4 independent MPPT controllers, each accepting up to 1000 W, cope well with mismatched orientations and partial shading, a genuine plus for balcony setups with uneven exposure. Factory output is capped at 800 W to fit typical grid-tied regulations, with an uplift to 1200 W available through professional installation. Expansion via BP2500 batteries up to 15.12 kWh, or up to 45.36 kWh by linking several units, leaves real room to grow. Our main reservation concerns availability: at the time of writing, the product is actively on sale in France and Germany, and we could not confirm a US launch date or US retailer for this model. For a first step into balcony storage with the inverter already built in, once it reaches your market, it is a solid option.
Marstek Saturn B2500-D
$2029.65 $811.05
(7)
The balcony battery that kicked off the trend in Germany: 2.24 kWh expandable to 8.96 kWh, 2 MPPT and 1600 W of solar input, IP65.
- Capacity: 2240 Wh (LiFePO4), expandable to 8960 Wh (4 units)
- Solar: 2 MPPT, up to 1600 W input
- Output: Built in 800 W micro inverter
- All weather: IP65, indoor and outdoor use
- The reference that started the balcony trend, unbeatable value
The Marstek Saturn B2500-D is the balcony solar storage system that popularised the whole category in Germany. DC coupled, its 2 independent MPPT trackers accept up to 1600 W of panels, with an 800 W micro inverter built in. Its 2240 Wh LiFePO4 battery is IP65 rated and expands up to 8960 Wh by stacking up to 4 units. Plug and play installation, control via the Marstek app, 10 year warranty, over 6000 cycles.
The B2500-D is more or less the model that started it all: in Germany it is hard to spot a balcony fitted with solar panels without one or more of these small grey towers stacked against the wall next to it. In practice, setup really does live up to the promised 15 minutes: MC4 connectors on the panels, a mains socket, the Marstek app over Wifi, and storage begins right away. Several owners report solid compatibility with Shelly smart meters and the German Ecotracker, with a genuine satisfaction at seeing the household's baseline consumption covered automatically in the evening. The clearest drawback concerns availability and price outside Germany: it is noticeably cheaper and far better distributed through the manufacturer at home than through the handful of resellers available elsewhere. The otherwise solid app also has occasional hiccups after an update, according to recent reports. For anyone able to buy at the German price, the value for money remains among the best in the whole plug and play category.
Anker Solix Solarbank 3 E2700 Pro
$2083.79 $1214.40
(7)
2688Wh of plug-and-play solar storage: 4 MPPT, a bidirectional 1200W microinverter and an AI that optimises your self-consumption on its own. Balcony solar finally pays off.
- Capacity: 2688 Wh (LiFePO4, expandable 16 kWh)
- Solar: 4 MPPT, up to 3600W PV input
- Inverter: Bidirectional 1200W (800W grid injection by default), plug&play

The Anker Solix Solarbank 3 E2700 Pro is a balcony solar storage battery, plug-and-play, that makes home solar genuinely worthwhile. Its 2688 Wh (2.7 kWh) of LiFePO4 store your panels' energy to release it in the evening or at peak hours, instead of losing it. It packs 4 MPPT controllers (up to 3600 W solar input), a bidirectional 1200 W microinverter, and above all Anker Intelligence, an AI that manages the flows on its own to maximise your savings. Its capacity expands to 16 kWh, and a smart meter avoids any waste.
In-depth reviewRead our full review →
4.1/5
The Solarbank 3 E2700 Pro reconciled us with balcony solar: without it, the energy produced during the day is fed to the grid and lost if no one consumes it; here, you store it to bring it back in the evening, when the home actually needs it. Installation is simple, genuinely plug-and-play, you connect the panels and the microinverter, and the app does the rest. The 4 MPPT let you connect several panels facing different directions with no loss, a real plus on a balcony or facade. What impressed us most is the Anker Intelligence AI: it learns our habits and decides on its own when to store, when to release and how much to feed in, without us having to think about it, which genuinely optimises the savings. The 2688 Wh capacity covers a good part of the evening consumption, and the expansion to 16 kWh lets you go bigger. Two honest caveats: the price remains an investment, to be paid back over several years, and the payback depends on your consumption profile and sunlight. But to make a balcony solar kit finally smart and worthwhile, it is a success.
Zendure AB3000X
$1136.01 $1081.85
(6)
The 2880 Wh LiFePO4 module of the SolarFlow 2400 AC generation: 17.28 kWh once stacked, IP65 with aerosol fire suppression, and tied to that one hub.
- Capacity: 2880 Wh (60 Ah, 48 V LiFePO4)
- Expandable: Up to 17.28 kWh with 6 modules
- Power: 2880 W on its own, 3840 W from two modules
- Cold weather: Self-heating from -4°F to 32°F (-20°C to 0°C)
- Safety: IP65, aerosol fire extinguishing system
- SolarFlow 2400 AC only, not the 2400 AC+ or 2400 Pro
The Zendure AB3000X is a 2880 Wh LiFePO4 storage module built for a single hub, the SolarFlow 2400 AC. Zendure's newer SolarFlow 2400 AC+ and SolarFlow 2400 Pro run on a different module, the AB3000L, and the brand states that the two families are not compatible with each other. The AB3000X is therefore the right reference for anyone who already owns a SolarFlow 2400 AC, and the wrong one for anyone buying into the current range. Within its own system it stacks up to six modules for 17.28 kWh, is rated for 6000 cycles, delivers 2880 W on its own and 3840 W from two modules, and comes in an IP65 enclosure with an aerosol fire extinguishing system and a 10-year warranty.
The AB3000X has to be read differently now that Zendure has moved its range on. It is the storage module of the SolarFlow 2400 AC generation, and of that generation alone. The newer SolarFlow 2400 AC+ and SolarFlow 2400 Pro are built around a different module, the AB3000L, which Zendure describes on its own product pages as compatible with those two hubs only and not compatible with the AB3000X or the SolarFlow 2400 AC. The statement runs both ways: an AB3000X will not extend an AC+, and an AB3000L will not extend a 2400 AC. Nothing in the model names makes that obvious, which is precisely why it belongs at the top of the page rather than in a footnote. What makes the split awkward is how close the two modules are on paper. Both hold 2880 Wh, that is 60 Ah at 48 volts of lithium iron phosphate, both are rated for 6000 cycles, both are IP65 and both carry an aerosol fire extinguishing system. The divide is architectural and commercial, not electrical. The one real difference favours the older module: the AB3000X is rated 2880 W on its own and 3840 W from two modules, against 1680 W and 1920 W for the AB3000L. Judged on its own terms the AB3000X is a serious block. Six modules bring the system to 17.28 kWh, the 48 volt architecture keeps conversion losses lower than the low-voltage packs of the previous range, and the self-heating function keeps the module working between -4°F and 32°F (-20°C and 0°C), which matters for an enclosure that stays outdoors all year. At 26.1 kg it is not something to move about, so its position should be settled before the first bolt goes in, and the 10-year warranty sits at the top of what this category offers. So the advice splits cleanly. If a SolarFlow 2400 AC is already installed, the AB3000X is the only module that will extend it, and Zendure still sells it for exactly that reason. If nothing is installed yet, the choice is between a discounted platform that has stopped evolving and the current one, and it has to be made before the first battery is ordered, because the batteries do not carry across.
Anker Solix Solarbank Max AC
$2435.85 (6)
7 kWh in pure AC coupling, no MPPT to manage: the plug-and-play battery that bolts onto any existing solar setup, up to 3500 W.
- Capacity: 7000 Wh (LiFePO4), expandable to 42 kWh
- Power: 3500 W charge/discharge, 3680 W backup
- Compatibility: 100% of rooftop PV inverters on the market
- All weather: IP66, self-heating down to -4°F (-20°C)
- 100% usable capacity, 5-minute installation
The Anker Solix Solarbank Max AC is a home storage battery that connects purely over AC, with no MPPT or direct solar input, making it compatible with 100% of rooftop PV inverters on the market. Its 7000 Wh capacity is 100% usable (no hidden reserve), with up to 3500 W of charge and discharge on the grid side, plus a 3680 W backup port for outage power. IP66 rated with self-heating down to -4°F (-20°C), it installs in 5 minutes with no complex wiring thanks to a stackable modular design. 10-year warranty, 10000 cycles, expandable up to 42 kWh with BP7000 modules.
In-depth reviewRead our full review →
4.0/5
The Solarbank Max AC fills a real gap: a large storage battery that simply bolts onto an existing rooftop solar setup, without going through an MPPT or swapping the inverter. The modular, wiring-free installation is a genuine advantage over conventional home batteries that require an electrician. The 3500 W of charge and discharge soaks up most of the midday production peak, and the 3680 W backup port switches over seamlessly during a grid outage. Using 100% of the stated capacity, with no hidden technical reserve, is a nice touch on paper. Our main reservation concerns early customer reviews, more mixed than usual for Anker: some reports flag software glitches on the very first units, worth watching before buying. For anyone who already has panels and just wants to add storage without redoing the whole setup, it is a serious option.
Zendure AB2000L
$973.53 $811.05
(6)
The 1920 Wh LiFePO4 storage module of the SolarFlow ecosystem, with aerosol fire suppression: 6000 cycles, expandable to 7.68 kWh, IP65 and a 10-year warranty.
- Capacity: 1920 Wh (LiFePO4, 40 Ah, 48 V)
- Expandable: Up to 7.68 kWh (4 batteries)
- Safety: Aerosol suppression, self-heating to -4°F (-20°C), IP65
- Lifespan: 6000 cycles, 10-year warranty
- Fireproof 1920 Wh stackable battery, affordable
The Zendure AB2000L is a 1920 Wh LiFePO4 storage module for SolarFlow balcony solar systems (Hub 2000, Hyper 2000). It stacks up to four units for 7.68 kWh. It includes an aerosol fire suppression system that smothers any fire without toxic gas, anti-thermal-runaway protection and self-heating down to -4°F (-20°C). Long-life cells (6000 cycles), an IP65 enclosure and a 10-year warranty make it a reliable, affordable extension for storing your solar energy.
The AB2000L is the new generation of extension battery for SolarFlow hubs (Hub 2000, Hyper 2000): with 1920 Wh per module, it already covers a good part of an evening, at a noticeably gentler price than the previous generation. It keeps the safety pitch that reassures on this kind of permanently installed product: an aerosol fire suppression system that can smother a fire without toxic gas, anti-thermal-runaway protection and an IP65 enclosure for the outdoors. The self-heating, which keeps it charging down to -4°F (-20°C), makes it a genuine outdoor battery, usable year-round. Stacking remains the ecosystem's great strength: you start with one battery, then add up to four (7.68 kWh). The LiFePO4 cells rated for 6000 cycles and the 10-year warranty reassure over the long run. The only real downside is its weight, which makes it worth choosing its spot carefully at install time. To extend an existing SolarFlow system without breaking the bank, it is now the most logical choice.
Indevolt SolidFlex 2000
$1352.65 $1081.85
(5)
A hybrid solar battery with semi-solid LiFePO4 cells, 4 built-in MPPT trackers and 2400 W bidirectional power, expandable up to 66 kWh across 3 stacked groups.
- Capacity: 1792 Wh semi-solid LiFePO4, 22 kWh per group (66 kWh with 3 groups)
- Solar: 4 x 600 W built-in MPPT, 2400 W max
- Power: 2400 W bidirectional, 10 ms backup switchover
- The only Indevolt model combining direct MPPT and semi-solid cells
The Indevolt SolidFlex 2000 is a plug and play solar battery that packs 4 built-in MPPT inputs (2400 W max solar) while staying compatible with an existing inverter. Its 1792 Wh semi-solid LiFePO4 capacity extends up to 22 kWh per group and up to 66 kWh across 3 parallel-stacked groups. It switches automatically in under 10 ms during a power cut, delivers up to 2400 W of output, and is app-controlled with dynamic electricity tariff support.
The SolidFlex 2000 first stands out for its semi-solid cell technology, a first on this balcony battery segment: Indevolt claims better thermal stability and stronger waterproofing than classic LFP cells, and in practice the unit inspires confidence, with a sturdy enclosure and a clear app for tracking production. The install stays true to the plug and play spirit: direct MPPT inputs for new panels, or AC coupling with an existing inverter, whichever suits you. The under-10-ms backup switchover does its job during outages, within the limit of 1000 W without an expansion battery (up to 2400 W with an SFA1800 or SFA3600). Two honest caveats: without expansion, backup power stays modest, and the price climbs quickly once you add SFA modules. But for a household that wants to combine direct MPPT with extra safety margin, it is a solid pick from Indevolt.
Zendure AB1000
$1218.60 $675.65
(5)
The 960 Wh LiFePO4 storage module of the SolarFlow ecosystem: compact (11.5 kg), expandable to 3.84 kWh, self-heating to -4°F (-20°C), IP65 and a 10-year warranty.
- Capacity: 960 Wh (LiFePO4, 20 Ah, 48 V)
- Expandable: Up to 3.84 kWh (4 batteries)
- All weather: Self-heating to -4°F (-20°C), IP65
- Weight: 11.5 kg, 10-year warranty
- Compact 960 Wh battery, the most affordable
The Zendure AB1000 is a 960 Wh LiFePO4 storage module for SolarFlow balcony solar systems (Hub 2000, Hyper 2000). Compact (11.5 kg) and compatible with the other AB batteries, it stacks up to four units for 3.84 kWh. Self-heating keeps it charging down to -4°F (-20°C) and the IP65 enclosure allows outdoor installation. With its 10-year warranty, it is the ideal entry-level extension to get into solar storage on a budget.
The AB1000 is the gateway to storage in the SolarFlow ecosystem: at 960 Wh and 11.5 kg, it is the lightest and most affordable of Zendure's extension batteries, ideal for a first step or a small balcony. It carries the essentials: an IP65 enclosure for the outdoors, self-heating that keeps it charging down to -4°F (-20°C), and the range's stacking logic (up to four units, or 3.84 kWh, and compatible with the other AB batteries to size your capacity). The 10-year warranty covers the whole thing. Two things to keep in mind: its capacity stays modest, so for genuine evening autonomy you are better off with the AB2000L or stacking several modules; and, unlike the newer versions, it does not have the aerosol fire suppression system reserved for the higher-end models. But to start out without investing too much and discover balcony storage, the AB1000 remains an excellent entry point.

2.4 kWh, 4 MPPT and 4800 W of total solar input: the balcony battery combining DC panels with AC coupling, expandable to 16.8 kWh.
- Capacity: 2400 Wh (LiFePO4), expandable to 16.8 kWh
- Solar: 4 MPPT (3000 W) + 1800 W via AC coupling, 4800 W total
- Output: 2400 W bidirectional AC
- All weather: IP65, self-heating battery
- Dual DC + AC solar input, 4800 W combined

3.9/5
The SolarFlow 2400 Pro stands out for its dual solar input: its 4 MPPT controllers capture up to 3000 W of panels directly, and an additional AC coupling path adds up to 1800 W from an existing setup, for 4800 W combined in theory. This combined ceiling has not yet been confirmed at full power in real-world conditions, with a ceiling closer to 2370 W observed in one tested configuration; each input taken separately, though, does perform in line with its promises. The 2400 W of bidirectional AC output is comfortable for quickly releasing the stored energy, and the round-trip efficiency comes out at 87 to 90 % across several independent measurements, a very good result for this type of product. The ZenKI AI assistant handles the switch between charging, discharging and grid resale well based on rates, with compatibility across more than 840 European providers, a real plus for anyone on a variable-price contract. Two things to know: several firmware anomalies are documented, including a discharge lockup after a full charge and a standby lockup that appeared after an update; and customer feedback mentions occasional Wi-Fi drops, fixed by reconnecting the unit to the router, with Wi-Fi otherwise remaining limited to the 2.4 GHz band. For scalable, versatile balcony storage, this remains a solid reference, provided you accept these software growing pains.
Indevolt BK1600 Ultra
$1014.15 $675.65
(3)
30% lighter and more compact than comparable balcony batteries, with EPS backup power switching in 10 ms and wireless expansion up to 4.9 kWh.
- Capacity: 1636 Wh LiFePO4, expandable to 4.9 kWh
- Solar: 2 x 600 W built-in MPPT, 1200 W max
- Format: 300 x 215 x 250 mm, 16 kg, IP54
- EPS backup power in 10 ms, missing on the standard BK1600
The Indevolt BK1600 Ultra is a plug and play solar battery packing 1636 Wh in a compact format (300 x 215 x 250 mm, 16 kg), built for a balcony or a small space. It has 2 built-in MPPT inputs (1200 W max solar) and stays compatible with an existing microinverter through AC coupling. Unlike the standard BK1600, it includes an EPS function that switches to battery in 10 ms during a power cut. Up to 3 units can be paired wirelessly to reach 4.9 kWh and 3600 W of output.
The BK1600 Ultra plays the compact card without cutting corners: its 16 kg and case the size of a large suitcase make it easy to fit on a tight balcony, and its two built-in MPPT inputs let you connect new panels directly without a third-party inverter. The EPS function, which switches to battery in 10 ms during an outage, is what really sets it apart from the base BK1600 for just $115.79 more. Control through the app is simple and clear, with real-time production tracking, though one review found on the manufacturer's own site notes the displayed savings figures are not always easy to follow. Its compatibility with Shelly and HomeWizard meters makes it a popular pick in the home-automation community. Its one real limit: 1200 W of output on a single unit, best reserved for everyday appliances rather than heavy loads. For a small household wanting backup power without blowing the budget, it is a solid choice.
Zendure SolarFlow 1600 AC+

Its capacity extends up to 11.52 kWh with additional AB2000L batteries. IP65 rated, backed by a 10-year warranty and controlled over Wi-Fi and Bluetooth via the Zendure app, it is the entry-level option in the new SolarFlow range.
In-depth reviewRead our full review →
3.8/5
The SolarFlow 1600 AC+ banks on simplicity: with no MPPT or direct solar input, it connects over AC to a setup already fitted with an inverter, with round-trip efficiency measured at 87.6% and a switchover to backup power in 15 to 20 ms during an outage. Its claimed compatibility with 100% of inverters on the market, however, rests on the manufacturer's reasoning rather than on third-party verification, and the software setup (additional smart meter, charge priority between generations) proves trickier than the hardware installation itself. The price of $832.71 remains confirmed and the unit available in stock, a real advantage over its direct competitor currently out of stock. For anyone who already has working panels and an inverter and just wants to add simple storage, a credible option, provided you accept a still-young software ecosystem and high return shipping costs if you change your mind.
Jackery HomePower 2000 Ultra
$777.93 (3)
A 2048 Wh plug and play balcony battery expandable to 8 kWh, dual 2000 W MPPT input, an 800 W micro-inverter, 10 year warranty, no electrician required.
- Capacity: 2048 Wh (LiFePO4), expandable up to 8 kWh
- Solar: Dual MPPT, up to 2000 W input
- Grid feed-in: 800 W micro-inverter, 80% charge in 52 min
- Safety: IP65, -4 °F to 131 °F (-20 to 55 °C), automatic fire suppression
- Expandable to 8 kWh, the lowest entry price in this comparison
The Jackery HomePower 2000 Ultra is a plug and play balcony solar storage battery that connects directly to photovoltaic panels and feeds the power they produce back into the home circuit, no electrician needed. Its 2048 Wh LiFePO4 battery charges through two MPPT inputs accepting up to 2000 W of panels, and feeds energy back through an 800 W micro-inverter. Capacity expands up to 8 kWh with add-on batteries, controlled from the Jackery Home app, backed by a 10 year warranty.
Setting up the HomePower 2000 Ultra really does come down to a few steps: plug in the panels' MC4 cables, screw the mains cord into a wall socket, and the Jackery Home app finds the unit within seconds. In practice, the dual MPPT design earns its keep as soon as the panels don't all face the same way, a south-facing balcony rail plus a west-facing side panel, for instance, a scenario a single-input system handles worse. The 800 W feed-in cap is nothing special, it's simply the market norm, but being able to stack up to three add-on batteries without touching the original setup is a genuine selling point once needs grow over time. A few user reports mention software tweaks needed in the first months after launch, the kind an app update fixes rather than a real hardware flaw. For a household that wants to cut its bill without heavy paperwork, this is a serious option and one of the more affordable ones in its category.
Fossibot FBP1200
$946.45 $811.05

In-depth reviewRead our full review →
3.5/5
The FBP1200 quickly found its place on our test balcony: two handles, a several-metre cable in the box and a wall socket are all it takes to get it running, no lengthy manual required. The display stays readable in bright sunlight, and the cooling fins stayed barely warm even after several hours of charging in hot weather. The backup mode impresses with its speed: the 1 ms switchover doesn't faze any sensitive device, but its exact electrical operation (dedicated outlet or full islanding) remains poorly documented by the manufacturer. The app, meanwhile, takes a bit of patience: the three modes on offer (green plan, custom, smart plug) become genuinely useful once you've got the hang of them, but the interface still has a few rough edges, and the $1057.47 in yearly savings promised by the built-in AI doesn't line up with the manufacturer's own calculation figures. Another real limitation: with 800 W fed into the grid and 1200 W off-grid, the battery struggles with the hungriest appliances; an electric kettle stalled it during our tests. For a fridge, a router, lighting or charging devices, though, it delivers without a hitch. There's still the Consuel question for this category pairing a battery with an inverter, not settled uniformly in France, and a track record that's still very limited (only six customer reviews, none from a French buyer), which calls for caution over the long run. A young, promising product on paper, best reserved for those who accept these documented reservations.
Zendure AiO 2400
See price and availability (2)
The all-in-one solar storage that combines a hub and a 2400 Wh battery in a sleek metal case: 2 MPPT, self-heating to -4°F (-20°C), IP65 and easy install.
- Capacity: 2400 Wh built-in (LiFePO4, 48 V)
- Solar input: 1560 W, 2 MPPT controllers

With two MPPT controllers (up to 1560 W of panels, 1200 W for charging), it connects to a microinverter to feed the stored energy in. Its slim metal design, self-heating down to -4°F (-20°C) and IP65 rating make it a polished, easy-to-install way to store your solar energy all year round.
In-depth reviewRead our full review →
3.3/5
The AiO 2400 takes the opposite approach to modular SolarFlow systems: instead of stacking a hub and batteries, everything sits in a single metal case, slim and genuinely elegant, one of the best-looking in the category. In use, its simplicity is what wins you over: you connect the panels to its two MPPT inputs, link a microinverter (often the bundled EZ1-M), and the built-in 2400 Wh battery does the rest, storing daytime energy to release it in the evening. The self-heating that keeps it charging down to -4°F (-20°C) and the IP65 rating make it a true outdoor product, usable year-round. The LiFePO4 cells last up to 4000 cycles at 80% (8000 at 70%), a sign of longevity, and the 10-year warranty reassures. Two caveats: its capacity is fixed (2400 Wh), so you need to size it right at purchase, with no stacking like on an AB system; and you have to add a microinverter for feed-in. But for a clean, good-looking, fuss-free balcony install, the AiO 2400 is one of the best options around.
Zendure SolarFlow 4000 Mix AC+
$3248.25 (2)
The retrofit that changes scale: 8 kWh expandable to 50 kWh, 4 kW bidirectional power, and a dedicated input for your existing solar inverter.
- Capacity: 8000 Wh LiFePO4, expandable to 50 kWh
- Power: 4000 W bidirectional, 5000 W in PV bypass

In-depth reviewRead our full review →
3.7/5
The SolarFlow 4000 Mix AC+ remains on pre-order more than four months after its launch, and the only customer feedback available so far offers a first glimpse: one buyer describes wiring it directly into a 20A breaker rather than a wall socket, a cleaner installation in his view, and says he has already raised output to 3000 watts without any issue. On paper, the 10-millisecond switchover to the off-grid output and the 7200 W peak leave headroom for appliances with a high startup current draw, such as a heat pump. Two reservations weigh on this early assessment, though: on a pre-production unit, the measured round-trip efficiency comes out at 87 % at full load and 78-82 % in real-world use, clearly below the announced 90 %, a measurement still to be confirmed on a production unit; and the HEMS 2.0 energy management system, which also controls this model, required an emergency software patch released in June 2026. The announced compatibility with major third-party inverter brands (Huawei, SMA, Fronius, Enphase, SolarEdge, Sungrow) has not yet been independently verified brand by brand. The real drawback at this stage remains the lack of hindsight: the launch happened on a very small scale, reviews can still be counted on one hand, and the pre-order shipping window (20 to 30 days) is worth watching before ordering.
Bluetti Balco 260
$1894.25 (1)
The Bluetti Balco 260 stores your balcony solar power in 2560Wh of LiFePO4, expandable up to 15.36kWh, with no electrician required.

Capacity scales up to 15,360Wh with additional BC260 batteries, and up to 92kWh when networking several units through the BLUETTI Space app.
In-depth reviewRead our full review →
3.6/5
The Balco 260 is a genuine step forward for anyone living in a flat: plugging a 2560Wh battery capable of soaking up 2400W of solar panels through its four MPPT trackers straight into a wall socket, with zero electrician required, is a promise it actually keeps. Setup is genuinely quick, and the app handles charging and discharging around electricity tariffs thanks to its built-in AI (AI-EMS). Its real strength is scalability: up to five extra BC260 batteries push capacity to 15,360Wh, and up to six units can coordinate wirelessly to cover an entire home. A few caveats are worth flagging: early independent tests measure round-trip efficiency around 79%, behind the best competitors, and standby draw a touch higher than Bluetti's own figures. The automatic charging mode has also shown a few questionable calls in early testing. Nothing dealbreaking for a first-generation product, but worth watching through future updates. As an uncomplicated way to start balcony solar storage, the Balco 260 remains a solid, scalable choice.
Zendure SolarFlow 2400 AC
See price and availability (1)
AC-coupled home storage rated 2400 watts and expandable past seventeen kilowatt-hours, sold on Amazon.com but currently listed unavailable.
- Power: 2400W charging and discharging
- Storage: 2880 Wh LiFePO4, expandable to 17.28 kWh

It is genuinely listed on Amazon.com, confirming real US availability, though the listing currently shows unavailable and carries only two reviews, both from France. Amazon notes plug-and-play covers 800W of output; more requires an electrician.
In-depth reviewRead our full review →
3.9/5
The SolarFlow 2400 AC deserves credit for one thing Marstek's comparable battery lacks: it is a real listing on Amazon.com, not just a marketing page. That said, our enthusiasm cools once you dig in. The listing currently shows unavailable, carries only two ratings, both from French buyers rather than American ones, and splits evenly between a five-star review praising the install and a one-star review describing Bluetooth pairing trouble after a hardware swap. Amazon's own product description is refreshingly blunt about the limits too: plug-and-play only covers 800 watts of grid output, and pushing past that requires a licensed electrician on a dedicated circuit, a different proposition from a simple wall-outlet install. The hardware itself, an AC-coupled unit that stores surplus power for evening use and expands to 17.28 kWh across six battery modules, is genuinely capable on paper, but between the unavailable listing, the thin non-US reviews, and the electrician requirement past 800 watts, this is a battery for an early adopter, not an impulse buy.
Bluetti Balco 500
$1851.54
5024 Wh, high-voltage MPPT and 4300 W of solar input, 3680 W bidirectional output: the bigger sibling of the Balco 260, built for residential-scale autonomy. Launch announced for September 2026.

- Power: 3680 W bidirectional, 800 W grid feed-in
- Network: Up to 6 units coordinated wirelessly via the BLUETTI app
- Built for full residential autonomy, beyond a simple balcony top-up
The Bluetti Balco 500 is a high-end balcony solar storage battery, designed for energy needs well beyond a simple top-up. Its 5024 Wh LiFePO4 battery charges through a high-voltage MPPT architecture (70-470 V), accepting up to 4300 W of solar panels directly, and delivers energy through a 3680 W bidirectional output, with 800 W of grid feed-in. Capacity extends up to 30 kWh with add-on batteries, and up to 6 units can coordinate wirelessly through the BLUETTI app to cover an entire home. Unveiled in Paris in May 2026 alongside the Balco 260, its commercial launch is announced for September 2026.
The Balco 500 targets a notably more ambitious use case than its smaller sibling the Balco 260: with 5024 Wh of base capacity and a 4300 W solar input through a high-voltage MPPT architecture (70-470 V), it is aimed at households wanting to go beyond a simple balcony top-up and pursue genuine residential autonomy. Its capacity, expandable up to 30 kWh, and the wireless coordination of multiple units make it a scalable solution built to grow with a household's needs. Not yet commercially available at the time of writing (launch announced for September 2026), we have not been able to test it ourselves or gather user feedback: this listing will be updated as soon as it becomes available, with a full review based on real-world use.
Allpowers BS2500 Pro
$1599.00
A capable 2600Wh plug-and-play balcony battery that has done well in Europe, but not yet sold through a US store or Amazon.com as of 2026.
- Capacity: 2600 Wh (LiFePO4), 2400W hybrid
- Solar: Dual MPPT, anti-backflow protection
- US status: No Amazon.com listing, no confirmed UL3700
- 2600Wh hybrid battery, not yet confirmed for the US
The Allpowers BS2500 Pro is a 2600Wh, 2400W plug-and-play balcony battery that stores solar production to release in the evening, a strong performer in the EU market with dual MPPT, anti-backflow protection and an IP65 rating. In the US, the picture is thinner: no listing on Amazon.com, no confirmed UL3700 certification, and Allpowers' only storefront for it, iallpowers.eu, ships to EU countries and Ukraine with no stated US shipping. Best treated today as a European product to watch rather than an order-ready US purchase.
On hardware alone, the BS2500 Pro earns its strong European reputation: 2600 Wh of LiFePO4 storage, 2400 W of hybrid grid and off-grid power, dual MPPT for panels facing different directions, and an IP65 rating built for a balcony or facade. This review, though, is about buying one in the US today, and there our enthusiasm drops fast. We found no listing anywhere on Amazon.com, and Allpowers' own storefront for this product, iallpowers.eu, offers free shipping across EU countries and to Ukraine, with no mention of the United States at all. No UL3700 certification turned up in our research either, the standard now used to clear plug-in solar storage for US self-install. None of this means the hardware is bad. It means the realistic path for a US buyer today runs through importing from Europe at your own risk on customs, voltage and warranty, not a straightforward domestic order. Readers wanting a genuinely US-available plug-and-play battery should compare this against EcoFlow's Stream Ultra, which currently has real Amazon.com and US-store presence.
Zendure SolarFlow 3000 Mix AC+
$2977.45 $2706.65
8 kWh in one block, 3000 W bidirectional: the most compact and affordable model in the SolarFlow Mix range, built for a small household or semi-mobile use.
- Capacity: 8000 Wh LiFePO4, not expandable
- Solar: Dedicated input for existing PV inverter, up to 3000 W
- Power: 3000 W bidirectional
- Mobility: Castor-mounted enclosure, IP65, -4°F to +131°F (-20°C to +55°C)
- The most affordable and compact model in the Mix range
The Zendure SolarFlow 3000 Mix AC+ is the entry-level model in the new SolarFlow Mix range, positioned as both a compact residential solution and a mobile energy station, for a household of around 2 people with an annual consumption around 3000 kWh. Unlike its bigger siblings, its 8000 watt-hour battery is not expandable, but it stays mounted on castors for easier moving. A dedicated 3000-watt input accepts an existing PV inverter directly, bidirectional power reaches 3000 watts, and a 3680-watt backup output (7200 watts peak) takes over during an outage, with a 10-15 ms switchover.
The SolarFlow 3000 Mix AC+ plays the simplicity card within the Mix range: a fixed 8000 Wh capacity with no expansion option, but a notably more accessible price than its two bigger siblings and a format designed to be moved more easily thanks to its castors. It is the best-suited model for a two-person household or semi-mobile use (small business, workshop, cabin). Its 3680 W off-grid output with a 7200 W peak remains generous for this entry segment, and the fast 10-15 ms switchover protects sensitive electronics during an outage. The most obvious limitation remains the lack of capacity expansion: for a household whose needs might grow, the 4000 Mix AC+ or Mix Pro offer more headroom. For a first step into home storage with stable consumption, it is a solid entry point within a well-thought-out product family.
Zendure SolarFlow 4000 Mix Pro
$3925.25
The most complete model in the Mix range: 8 kWh expandable to 50 kWh, dual high-voltage MPPT at 8 kW, dedicated third-party inverter input, up to 13 kW total solar input.
- Capacity: 8000 Wh LiFePO4, expandable to 50 kWh
- Solar: Dual MPPT 8 kW + third-party inverter input 5 kW, 13 kW total
- Power: 4000 W bidirectional, 5000 W in PV bypass
- Backup: Off-grid output 3680 W, 7200 W peak, 10 ms switchover
- Only model in the Mix range with built-in dual high-voltage MPPT
The Zendure SolarFlow 4000 Mix Pro is the most complete model in the new SolarFlow Mix range, aimed at households with an annual consumption around 7000 kWh. Unlike the purely AC-coupled SolarFlow 4000 Mix AC+, the Mix Pro integrates a dual high-voltage MPPT controller (30-400V) allowing direct connection of new solar arrays, while keeping a dedicated 5000W input for an existing third-party PV inverter. Combined, these two inputs reach up to 13000W of total solar input. Native capacity of 8000 Wh extends up to 50 kWh, bidirectional power reaches 4000 watts (5000W in PV bypass), and a 3680-watt backup output (7200 watts peak) takes over during an outage, with a 10 ms switchover.
The SolarFlow 4000 Mix Pro sets itself apart from its smaller sibling, the 4000 Mix AC+, with a genuine technical edge: its dual high-voltage MPPT controller (30-400V, 8 kW) allows direct connection of new panels without relying on a third-party PV inverter. Combined with the dedicated 5000W input for an existing inverter, it can pool up to 13 kW of solar input, a rare figure in this segment of modular home batteries. On paper, the 10 ms switchover to off-grid output and the 7200-watt peak leave good headroom for high-inrush appliances like a heat pump. Our main reservation at this stage concerns availability: we could not confirm a US retailer currently stocking this model, a point worth checking directly before ordering. For an ambitious new solar installation or a high-consumption household, it remains the most complete option in the Mix range on paper.

- Adds to an existing solar setup, no inverter needed
The EcoFlow Stream AC 5000 is a 5024 Wh home storage battery built to connect over AC to a balcony solar system that already has a microinverter. Unlike the Stream Ultra X or the plain Stream 5000, it has no built-in inverter and no direct solar input: it is pure storage, exchanging up to 3000 W with the rest of the setup. Rated IP65 and for use from -4 °F to 131 °F (-20 °C to 55 °C), it can be expanded to 15 kWh per tower with EB5000 battery packs, and up to 90 kWh by combining several towers. Announced on 20 August 2026, it remains on pre-order in most markets.
EcoFlow Stream Ultra
$1399.00
The first EcoFlow balcony-style solar battery sold for US homes: 1920 Wh, a built-in inverter, and self-install currently legal in Utah.
- Capacity: 1920 Wh LiFePO4, expandable to 11.52 kWh
- Solar input: 4 MPPT, up to 2000 W of panels
- Output: 1200 W AC outlets or 800 W to the grid
- Grid: 120V / 60Hz, NEMA 4 outdoor rating
- First plug-and-play solar battery legal in Utah
The EcoFlow Stream Ultra is EcoFlow's plug-and-play home solar battery for the US, launched in 2025 alongside Utah's HB 340 law. It packs a 1920 Wh LiFePO4 battery, a built-in hybrid inverter and 4 MPPT solar inputs (up to 2000 W of panels) into one unit that plugs into a standard 120V/60Hz outlet. Stored energy feeds the grid at up to 800 W, or powers its own AC outlets at up to 1200 W during an outage. EcoFlow currently markets self-install specifically for Utah, under HB 340's exemption from permits and interconnection agreements.

3.8/5
EcoFlow deserves credit for being first to market: the Stream Ultra is the first serious attempt at bringing Germany's balcony solar idea to the US, built around Utah's brand new HB 340 law instead of a legal gray area. Setup genuinely lives up to the plug-and-play promise: wire the panels to the four MPPT inputs, plug the unit into a standard 120V outlet, and the built-in inverter plus the EcoFlow app handle the rest, no electrician involved. In practice, our reservations are less about the hardware than the rollout. The unit showed as sold out at EcoFlow's own US store at the time of writing, and EcoFlow is explicit that self-install is currently sanctioned in Utah only, so shoppers elsewhere would need a licensed electrician and a standard utility interconnection agreement rather than a simple wall outlet. The 1920 Wh capacity also covers less of an evening's use than the larger Stream Ultra X sold in Europe. For a Utah household ready to work around stock, though, it is a genuinely fast, low-friction way into solar self-consumption.
Izypower Titan 2400
$878.75
A 2010 Wh plug and play balcony battery with a 2400 W hybrid micro-inverter, 4 independent MPPT inputs and a 15 year warranty, the longest on the market.
- Capacity: 2010 Wh (LiFePO4), expandable up to 12 kWh
- Solar: 4 independent MPPT, up to 2400 W input
- Micro-inverter: 2400 W built-in, over 96% efficiency
- Warranty: 15 years, 8000 cycles at 70% depth of discharge
- 2400 W micro-inverter, the longest warranty in its class
The Izypower Titan 2400, sold by French retailer MaterFrance, is a plug and play balcony solar storage battery with its own built-in hybrid micro-inverter. Its 2010 Wh LiFePO4 battery charges through 4 independent MPPT inputs rated at 600 W each, and feeds energy back into the home circuit at over 96% efficiency. Expandable up to 12 kWh with add-on Link modules, it's controlled from the IZYPOWER or ENERGY EASE app, backed by a 15 year manufacturer warranty, among the longest on the market.
Setting up the Titan 2400 comes down to three steps: screw the mains cable into a dedicated socket, plug the panels' MC4 cables into the four MPPT inputs, and the IZYPOWER app finds the unit within minutes. In practice, having four independent MPPT inputs instead of two lets you spread panels across roof faces or a balcony rail with different orientations without losing yield. The Titan 2400's real selling point is its 2400 W micro-inverter, two to three times more powerful than most rival balcony batteries capped at 800 W, plus a 15 year warranty, the longest we've seen on this segment. Some users report that solar production stops once the battery hits 100% rather than powering the home directly, and that the app, still young, could use some polish. MaterFrance, the French retailer behind the Izypower brand, is also a smaller outfit than the Jackery or EcoFlow names in this comparison, with stock sometimes limited. For a household wanting maximum solar injection power without stacking separate micro-inverters, it's a serious, well thought out option.
Marstek Venus E 3.0
$1549.00
A capable 5.12 kWh AC-coupled battery from Europe's balcony solar boom, but not yet sold or certified in the US as a self-install plug-in kit.
- Capacity: 5120 Wh LiFePO4, expandable to 15.36 kWh
- Backup output: 2.5 kW continuous during an outage
- Install: AC-coupled behind an existing grid-tied inverter
- US status: No confirmed UL3700 certification as of 2026
- Best used today as a backup add-on, not a solo plug-in kit
The Marstek Venus E 3.0 is a 5.12 kWh AC-coupled home battery that has done well in Europe, adding storage behind an existing solar inverter. In the US, the picture differs: no confirmed UL3700 certification, no live US storefront (its English page still prices in euros, its Where to Buy page reads coming soon), and no Amazon.com listing. Marstek notes its 800W grid-export mode needs local utility or government approval. Best treated as a battery to discuss with a licensed installer for backup use, not a Utah-style plug-in purchase.

3.6/5
On the strength of the hardware alone, the Venus E 3.0 deserves its European reputation: a genuinely simple AC-coupled battery that adds real backup capacity behind an existing solar setup. But this review is about buying one in the US today, and there our enthusiasm cools. We could not find it listed on Amazon.com, and Marstek's own English-language US page still displays its price in euros, with a Where to Buy page that literally reads coming soon. No UL3700 certification turned up in our research either, the standard now used to clear plug-in battery products in the US. Marstek's own site is upfront that pushing the full 800 W of on-grid output requires local utility or government approval, a different proposition from EcoFlow's Utah-cleared, no-approval devices. None of this means the hardware is unsafe or unusable. It means the realistic US path today runs through a licensed installer, adding it behind an existing interconnected system for its 2.5 kW backup output, not ordering it online expecting a Utah-style wall-outlet install.

It's a storage battery that already has everything it needs to run on its own: a bidirectional inverter, a charge controller, and often a control app. It plugs straight into a wall socket or into your existing panels, with no complex wiring and no need for a professional.
No, that's the whole point of this format: plugging into a standard mains socket, or into an existing solar inverter, is enough. A professional is only needed for a direct connection to the fuse board, which stays optional depending on the model.
Work out the evening and overnight consumption you want to cover: a household using 1 to 2 kWh in the evening is already well served by an entry-level model around 1 to 2.5 kWh, while a whole house will more likely need 5 kWh or more, with the option to expand capacity with extra modules on most ranges.
It depends on the model: some offer a backup output that switches over within milliseconds to power priority devices, others don't. Check this spec on each product page before buying if that use case matters to you.
Yes, that's actually one of the main uses: AC-coupled models sit downstream of an existing solar inverter, without touching the installation already in place, to add storage to a system that didn't have any.
