Jackery HomePower 2000 Ultra combines a bidirectional inverter and a lithium iron phosphate battery in one body: it installs on the ground, on a balcony, in a garage or a courtyard, and connects to both solar panels and the home grid. Feed-in to the grid stays within the 800 VA limit of German balcony system regulation, by default.
The built-in battery stacks with other modules of the same type: you start with a single tower and grow when more energy is needed, without changing the control unit. It manages the switch between sun, battery and grid on its own according to the mode chosen in the app, and can also charge the battery from the grid when the sun isn't enough. Below zero it preheats the cells before charging them, and on a balcony, in winter, that isn't a theoretical case.
Setup goes through the Jackery Home app, where the grid code for your operator is also set: without registering and without connecting to Wi-Fi the system still starts working on its own in self-consumption mode, but choosing how it works needs the phone. It suits anyone who has already decided to produce energy on the balcony or in the courtyard and wants a battery that grows with the system, not anyone looking for storage to carry around.

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.
