SolarFlow 2400 AC+ already holds a battery inside the control unit's body, but it has no panel inputs of its own: it connects downstream of an existing rooftop solar system and exchanges energy with the home grid through its cable with a Schuko plug. When the base capacity isn't enough anymore, dedicated satellite packs attach under the control unit, up to six units in total.
The body also has an outlet that keeps supplying power when the grid goes down, but it ships off by default: it turns on from the app when needed and closes again afterward. In basic mode it feeds up to 800 W back into the grid; a more aggressive mode reaches 2,400 W, within local grid feed-in rules. The app also tracks the energy price when it varies over time, and shifts the battery's discharge toward the more expensive hours.
It mounts on a wall with the included brackets. When the temperature drops below zero, internal self-heating kicks in, so charging doesn't stop. The first startup needs the app and a registered account. It's the choice for anyone who already has panels on the roof and prefers a battery already included, with the option to grow it later.

The rest of the data comes from one page 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.
