Zendure SolarFlow 800 Pro is a balcony storage unit with the battery already inside the body of the device, plus four independent panel inputs, each with its own MPPT tracker. The starting capacity expands by adding more batteries from the same series, up to six units in total.
It also has a dedicated outlet that keeps supplying power during a power outage, independent from the grid: it has to be activated from the app in advance, though, and it only powers what's plugged into that outlet, not the rest of the home. That same outlet, if left uncovered or used without the waterproof cap it's meant to have, makes the control unit lose the rain protection it keeps on the rest of the body.
The system decides on its own when to charge the battery from the grid or from the sun, following the cheapest hours, and it's controlled from the Zendure app over Wi-Fi or Bluetooth.

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.
