Detailed overview: Growatt NOAH 2000 DC-coupled balcony solar battery, 2 MPPT
The Growatt NOAH 2000 is one of the best-selling balcony solar storage batteries in Europe, standing out through its DC-coupled design: unlike batteries that connect to the AC output of an existing setup, the NOAH 2000 sits between the solar panels and a microinverter, directly on the direct current produced by the panels. This architecture requires a compatible microinverter downstream, with Growatt offering its own NEO 800M-X for this purpose.
Its 2 MPPT controllers accept up to 1800 W of panels, with a stated 99% conversion efficiency, and up to 4 panels can be connected. Its 2048 Wh LiFePO4 battery is rated for 6000 charge cycles, and its capacity extends up to 8192 Wh by stacking up to 4 NOAH 2000 modules.
IP66 certified against water and dust, it includes a heating film that allows continuous charging and discharging even in severe cold, with an operating range from -4 °F to 113 °F (-20 °C to 45 °C). Installation is designed to be plug-and-play, with no professional required, and control is handled through the Growatt app over Wi-Fi and Bluetooth.
Backed by a 10-year warranty, the NOAH 2000 owes its popularity to an excellent price-to-performance ratio, regularly promoted through deals at specialist retailers, particularly in Germany where its distribution is most developed.

Comparison
How does the Growatt NOAH 2000 compare with other plug-and-play balcony batteries, for searches like "best affordable balcony battery"? Here is how it stacks up against two references already in the catalogue: the Zendure AB2000L and the Anker Solix Solarbank 3 E2700 Pro.
| Criterion | NOAH 2000 | Zendure AB2000L | Solarbank 3 E2700 Pro |
|---|---|---|---|
| Capacity | 2048 Wh | 1920 Wh | 2688 Wh |
| Coupling | DC, with dedicated microinverter | DC, with Zendure hub | DC, built-in inverter |
| Solar input | 1800 W (2 MPPT) | Variable (via hub) | 1200 W (4 MPPT) |
| Expandable | 8192 Wh | Up to 17.28 kWh | Up to 16 kWh |
| Observed price | ≈ $450.44 | ≈ $693.25 | ≈ $1214.54 |
In short, the NOAH 2000 stands out for its excellent value for money and strong reputation in the German market. The Zendure AB2000L needs a separate hub but offers better expandability, while the Solarbank 3 Pro packs its inverter directly for a simpler install, at a notably higher price. For a first step into balcony storage at the best price, the NOAH 2000 remains a solid reference.

Our tester's review: Julien De Jurquet
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.

In DC coupling, the battery sits directly between the solar panels and a microinverter, on the direct current. In AC coupling, the battery connects after an inverter already in place, on the alternating current. The NOAH 2000 therefore requires a compatible microinverter downstream, such as the Growatt NEO 800M-X.
Up to 4 panels, spread across its 2 MPPT controllers, for a total solar input of 1800 W.
Yes, up to 4 NOAH 2000 modules can be stacked, bringing total capacity up to 8192 Wh.
Yes, a built-in heating film allows continuous charging and discharging, with a stated operating range of -4 °F to 113 °F (-20 °C to 45 °C).
Its distribution remains concentrated in the German market through specialist retailers at the time of writing, with still-limited presence elsewhere in Europe.
