Detailed overview: Zendure SolarFlow 1600 AC+ AC-coupled balcony solar battery
The Zendure SolarFlow 1600 AC+ is the entry-level variant of the new SolarFlow range, built to complement a balcony solar setup already fitted with a PV inverter, without going through direct solar regulation. Unlike the SolarFlow 2400 Pro, which packs 4 MPPT controllers, the 1600 AC+ connects purely over AC, making it 100% compatible with rooftop PV inverters already installed, regardless of brand.
Its 1920 Wh LiFePO4 battery exchanges up to 1600 W of bidirectional AC power, enough to cover most of a household's electrical needs. Its on-grid and off-grid ports ensure uninterrupted power during a grid outage, and its capacity extends up to 11.52 kWh by adding AB2000L expansion batteries.
IP65 rated and backed by a 10-year warranty, it is controlled through the Zendure app over Wi-Fi and Bluetooth, with the same tariff intelligence as the rest of the SolarFlow range: charge and discharge optimisation based on compatible European energy providers.
The SolarFlow 1600 AC+ is aimed specifically at anyone who already has a working balcony solar setup and wants to add storage at the best price, without rethinking the solar electronics already in place.

Comparison
How does the Zendure SolarFlow 1600 AC+ compare with other AC-coupled balcony solar batteries, for searches like "solar battery compatible with existing inverter"? Here is how it stacks up against two references already in the catalogue: the Zendure AB2000L and the EcoFlow Stream AC Pro.
| Criterion | SolarFlow 1600 AC+ | Zendure AB2000L | EcoFlow Stream AC Pro |
|---|---|---|---|
| Capacity | 1920 Wh | 1920 Wh | 1920 Wh |
| AC output | 1600 W bidirectional | 800 W grid | 1200 W (2300 W with two units) |
| Backup power | Yes, on-grid/off-grid | No | Yes, up to 1200 W |
| Expandable | 11.52 kWh | Up to 7.68 kWh | 11.52 kWh |
| Observed price | ≈ $832.56 | ≈ $693.25 | ≈ $946.45 |
In short, the SolarFlow 1600 AC+ stands out for the highest output power in this comparison (1600 W) and its built-in backup function. The Zendure AB2000L stays cheaper but needs a separate hub to work, while the Stream AC Pro offers comparable power with the option of pairing two units. For anyone who wants to add powerful storage to an existing setup without an extra hub, the SolarFlow 1600 AC+ is a coherent choice.

Our tester's review: Julien De Jurquet
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.

No, it connects purely over AC and works with 100% of rooftop PV inverters already installed, regardless of the panel or inverter brand.
The SolarFlow 1600 AC+ has no MPPT or direct solar input: it connects purely via AC coupling. The 2400 Pro additionally packs 4 MPPT controllers to wire panels directly, with higher output power (2400 W versus 1600 W).
Yes, its on-grid and off-grid ports ensure uninterrupted power during a mains outage.
Yes, up to 11.52 kWh by adding AB2000L expansion batteries, sold separately.
Yes, and above 800 W of inverter output, this installation moves out of the plug-and-play solar kit format: it follows the standard grid-connection procedure with Enedis, with a systematic Consuel certificate and the involvement of a qualified installer.
