Detailed overview: Zendure SolarFlow 800 Pro balcony storage kit
The Zendure SolarFlow 800 Pro is an all-in-one storage system for balcony solar (Balkonkraftwerk), built to make self-consumption genuinely worthwhile. It combines a bidirectional hybrid microinverter with one or more AB2000X batteries, storing the energy produced during the day to release it in the evening or at peak hours instead of losing it.
Its microinverter delivers up to 800 W feeding the home grid (and 1000 W off-grid), while accepting a generous solar input of 2640 W (4 x 660 W), enough to cover large balcony, terrace or garden arrays. On the storage side, each AB2000X battery offers 1920 Wh of LiFePO4, and the system expands up to five batteries, or 11.52 kWh, enough to get through a whole evening or even a night on stored solar energy.
Where the SolarFlow 800 Pro stands apart is its 48 V architecture, which cuts losses by roughly 25 % compared with the previous 16 V generation, paired with gallium-nitride components (3rd-gen GaN) to limit conversion losses. The result is better efficiency, from the panel all the way to the socket. Local regulation is fast (response in under 3 seconds, watt-level adjustment), so it hugs the home's actual consumption and avoids feeding the grid for free.
Built for the outdoors, the whole set is IP65 rated against rain and dust, and the batteries feature self-heating technology that keeps them working down to -20 °C. Control runs through the Zendure app (Wi-Fi and Bluetooth), with a real bonus for advanced users: deep smart-home integration, up to Home Assistant, much appreciated in the balcony-solar community. Backed by a 10-year warranty, it is a durable way to store your solar energy with no heavy work and no changes to your electrical panel.

Comparison
How does the SolarFlow 800 Pro stack up against other balcony-solar storage solutions?
| Criterion | Zendure SolarFlow 800 Pro | Anker SOLIX Solarbank 2 Pro | EcoFlow PowerStream |
|---|---|---|---|
| Built-in inverter | Yes, 800 W | Yes, 600 W | Yes, 600 to 800 W |
| Architecture | 48 V | High voltage | Separate battery |
| Expandable storage | Up to 11.52 kWh | Up to 9.6 kWh | Depends on third-party battery |
| Home Assistant | Yes, deep | Partial | Partial |
| Max solar input | 2640 W | 2400 W | Variable |
Against the Anker SOLIX Solarbank 2 and the EcoFlow PowerStream, the SolarFlow 800 Pro stands out with its 800 W inverter, large expandable capacity and, above all, its very polished smart-home integration, a decisive factor for the balcony-solar community that wants to fine-tune self-consumption.

Our tester's review: Julien De Jurquet
We hooked the SolarFlow 800 Pro up to an existing balcony setup, and the plug-and-play promise largely holds: the microinverter plugs into a standard household socket, and the Zendure app walks you through setup in a few minutes. The real benefit shows in the evening: energy stored during the day in the AB2000X flows back into the home when consumption peaks, instead of being pushed to the grid for free. Over several weeks, the self-consumption share climbed noticeably. What stood out is how fine the regulation is: the watt-level adjustment really tracks the household's draw, and the response is near instant. Tinkerers will love the Home Assistant integration, which unlocks advanced automations few rivals handle this well. Two honest caveats: the entry price stays high until you stack several batteries to amortise it, and payback depends heavily on your consumption profile and sunlight. But to turn a balcony array into a genuine, expandable storage system with no rewiring, the 800 Pro is one of the most polished options around.
Frequently asked questions: Zendure SolarFlow 800 Pro balcony storage kit
The microinverter can feed solar production straight to the grid, but the whole point of the 800 Pro is storage: you need at least one AB2000X battery (1920 Wh) to bank the energy and release it in the evening.
Up to 11.52 kWh by stacking five AB2000X batteries of 1920 Wh each. You can start with a single battery and grow the system over time, to suit your needs and budget.
Yes. The SolarFlow 800 Pro is controlled through the Zendure app (Wi-Fi and Bluetooth) and offers deep smart-home integration, including Home Assistant, popular for finely automating self-consumption.
The set is IP65 rated against rain and dust, and the batteries include self-heating that keeps them working down to -20 °C, which suits a year-round outdoor installation.
