Detailed overview: Zendure SolarFlow 800 Plus 1920 Wh balcony battery
The Zendure SolarFlow 800 Plus is an all-in-one balcony power unit: an 800 W hybrid microinverter and a 1920 Wh lithium iron phosphate battery share the same enclosure. It is the brand's most integrated answer to the central problem of balcony solar, namely that production happens while the home is empty.
On the solar side, the unit accepts up to 1500 W of panels split across two 750 W inputs, each with its own MPPT tracker, over a 14 to 55 volt DC range. That configuration allows four panels of around 400 W, or two high-output bifacial modules facing different directions without one penalising the other.
On the grid side, AC output is capped at 800 W, the limit that applies to balcony installations in most European countries. Grid charging input reaches 1000 W: it fills the battery during off-peak hours or low-price windows, then empties it when electricity is expensive. Stated panel-to-battery efficiency reaches 96 %.
The starting capacity of 1920 Wh extends to 11.52 kWh by stacking up to five extra batteries such as the Zendure AB2000L. The enclosure is IP65 rated, protected against dust and water jets, which allows outdoor installation without a cabinet. It measures 393 x 236 x 242 mm for 21.1 kg.
If you do not need storage right away, the SolarFlow 800 on its own costs far less and can be completed later. And if you are after more solar input and AI-driven management, look at the SolarFlow 800 Pro 2. The brand's 500 W bifacial panels are the natural companion.

Comparison
Zendure now offers three entry points into balcony storage. The table makes clear what each one brings.
| Criterion | SolarFlow 800 Plus | SolarFlow 800 | SolarFlow 800 Pro 2 | EcoFlow Stream Ultra X |
|---|---|---|---|---|
| Built-in battery | 1920 Wh | None | 1920 Wh | Yes |
| Solar input | 1500 W (2 MPPT) | 1200 W (2 MPPT) | 2640 W (4 MPPT) | High |
| AC output | 800 W | 800 W | 1000 W | 800 W |
| Maximum expansion | 11.52 kWh | 11.52 kWh | 3.84 kWh | Modular |
| Observed price | ≈ 539 € | ≈ 149 € | ≈ 779 € | ≈ 1199 € |
The SolarFlow 800 alone remains unbeatable as a starting point, but you then have to add an external battery to get the same result, which ends up costing more and taking up more room. The Pro 2 steps up to four MPPT trackers and adds AI management, a genuine plus if your balcony is large or your panels awkwardly oriented, but its expansion stops at 3.84 kWh. The 800 Plus holds the middle ground: immediate capacity, very high expandability, contained price.

Our tester's review: Julien De Jurquet
Balcony solar has long suffered from one simple flaw: it produces when nobody is home. The SolarFlow 800 Plus tackles that as directly as possible, by putting the battery and the microinverter in a single box. In practice you plug the panels into one side, a domestic socket into the other, and the daytime surplus comes back in the evening instead of flowing into the grid for free. Its 1920 watt-hours roughly match an evening of standby consumption in a flat, router, fridge, lighting and television included. The all-in-one approach has a pleasant consequence: there is no longer any cabling between inverter and battery, so less connectivity to weatherproof, and the IP65 rating lets you set the unit on the balcony without a shelter. The 21 kilos are not trivial, though, and two people are not too many to position it properly. Two things genuinely set it apart from the competition. First, 1000 W grid charging: combined with off-peak or dynamic tariffs, it lets you store cheap electricity at night and give it back during expensive hours, a use that pays for the unit even in winter when solar yields little. Second, expandability: five additional batteries take the system to 11.52 kWh, leaving the door open without replacing anything. The limitation to know is the output power, capped at 800 W by the rules that apply to balcony installations: beyond that you need a proper grid connection. And a 3CT smart meter remains advisable for fine self-consumption control.
Frequently asked questions: Zendure SolarFlow 800 Plus 1920 Wh balcony battery
Yes, like any grid-connected solar installation. In France a declaration to the network operator is required, in Germany registration in the Marktstammdatenregister is too. The 800 W output limit corresponds precisely to the simplified regime for balcony installations.
Yes, the enclosure is IP65 rated, protected against dust and water jets. A shaded, ventilated spot is still preferable: like any lithium battery, it does not enjoy prolonged extreme temperatures.
To store electricity when it is cheap, overnight or during off-peak windows, and give it back at peak hours. That is what keeps the unit useful in winter, when a balcony's solar production becomes marginal.
Up to 11.52 kWh by adding as many as five extra batteries from the range, without replacing the main unit. That is this model's main advantage over the SolarFlow 800 Pro 2, which stops at 3.84 kWh.
