Detailed overview: Zendure SolarFlow 800 Pro 2 balcony battery
The Zendure SolarFlow 800 Pro 2 is the brand's flagship balcony power unit: a hybrid microinverter, a 1920 Wh lithium iron phosphate battery and an intelligent energy manager in one device, fitted between the panels and a domestic socket.
Its distinguishing feature is the solar stage. Four independent MPPT trackers of 660 W each accept 2640 W of panels in total. On a conventional two-input installation, two differently oriented modules penalise one another because the inverter settles for a compromise. Here each one works for itself, which matters a great deal on an apartment balcony where panels are often split between railing and wall.
AC output is capped at 800 W when feeding the grid, like the rest of the range: that is the ceiling of Europe's simplified balcony-solar regimes. It rises to 1000 W off-grid, when the unit powers a socket directly during an outage, and grid charging also peaks at 1000 W. Bidirectional means the unit can both feed the home and draw from the grid to fill the battery, with a low-voltage start that lets production begin early in the morning.
The built-in 1920 Wh battery accepts up to five add-on AB1000 or AB2000 batteries, such as the Zendure AB2000L, for 11.52 kWh at most. The energy management system connects to over 840 European electricity suppliers across 32 markets to exploit hourly tariffs, and pairs with the brand's 3CT smart metre for real-time consumption tracking.
If solar input is not your constraint, the SolarFlow 800 Plus reaches the same 11.52 kWh ceiling for considerably less, with two MPPT trackers instead of four. And to start small, the SolarFlow 800 on its own remains the most affordable way into the ecosystem.

Zendure's whole balcony range revolves around the same principle, but the trade-offs differ markedly from one model to the next.

The question to ask is simple: is your limit the panel area or the storage capacity? If you can install a lot of solar, or if it faces awkwardly, the Pro 2's four trackers are worth the premium. If you mainly want to accumulate energy, the SolarFlow 800 Plus costs two hundred pounds less for the same 11.52 kWh ceiling. The previous-generation SolarFlow 800 Pro remains an option if you find it discounted.
Our tester's review: Julien De Jurquet
The SolarFlow 800 Pro 2 answers a problem balcony owners know well: perfectly south-facing surfaces are rare. With four independent 660 W MPPT trackers, each panel works at its own maximum power point. A module in shade at the end of the day no longer drags the others down, which genuinely changes things on a block facade where panels often end up on two different planes. That is the real technical argument of this version, more so than the 2640 W ceiling, which few balcony installations will ever reach. Grid export stays capped at 800 W, exactly like the rest of the range: the headline 1000 W figure covers off-grid output and charging from the mains, not what reaches the home. The onboard energy manager connects to more than 840 European suppliers and exploits hourly tariffs: it charges when electricity is cheap, discharges when it is expensive, and protects the battery in winter by keeping it above an unfavourable state of charge. On paper, that is what the best domestic systems do, at balcony scale. Two reservations. Price first: the SolarFlow 800 Plus reaches the same 11.52 kWh ceiling for over two hundred pounds less, as long as two solar inputs are enough for you. And since the product is recent, it does not yet have enough reviews to derive a reliable rating, which is why we do not display one.

Each tracker seeks the maximum power point of its own panel. With a single tracker for two awkwardly oriented modules, the inverter settles for a compromise and loses yield. With four independent inputs, a shaded panel no longer penalises the others, which is common on an apartment balcony.
11.52 kWh, by adding up to five AB1000 or AB2000 batteries to the built-in 1920 Wh. A single AB2000L already takes the set to 3840 Wh.
The system reads your supplier's hourly tariffs, the weather forecast and your consumption habits to decide when to charge the battery and when to empty it. In winter it also protects the cells by keeping them above an unfavourable state of charge.
No. Zendure rates grid export at 800 W maximum, the ceiling of the simplified regimes that apply to balcony installations. The 1000 W figure covers off-grid output and charging from the mains.
Yes, like any grid-connected solar installation, though the paperwork depends on where you live: registration in the Marktstammdatenregister in Germany (no separate grid-operator notification needed since the Solarpaket I reform), a declaration to Enedis in France (plus a Consuel safety certificate if wired into a dedicated circuit), a communication to the local distributor under CEI 0-21 in Italy, and registration under the RD 244/2019 self-consumption regime in Spain. Check the current rules where you live before commissioning it.
