Zendure SolarFlow 800 Plus is a balcony storage unit with a 1.92 kWh battery already inside the body of the device: two panel inputs and an inverter that exchanges energy with both the home grid and the internal cell. Unlike the base version of the same family, which is only a microinverter with no reserve of its own, here the capacity is already there from the first installation, and it expands by adding more batteries from the same series, up to six units in total.
The system can also charge the battery from the grid, not only from the sun, and decides on its own when to do it to take advantage of the cheapest hours. Besides its own app, it integrates with Home Assistant, for anyone who wants to see its data together with the rest of a smart home instead of in a separate app.
Initial setup, choosing the operating mode and remote control, though, always go through the Zendure app over Wi-Fi: without a stable network the system can't be set up or monitored remotely. It's certified for direct grid connection in both Germany and France.

The rest of the data comes from 2 pages on the manufacturer's site, cited row by row in the table above.
A manual or a datasheet counts as a source even when the original file is hosted elsewhere: what matters is the document, not the server. Where that happens, it is stated above.
These numbers are calculated, not stated: they have no source to cite, they have a formula you can redo. The price used is the manufacturer's list price, which is stable and the same in every country — not a shop's price on the day.
Chosen by the declared use tier and footprint, not by price: we don't publish prices.
