This module isn't standalone storage: it's the battery added to an already installed HomePower 2000 Ultra, when the starting capacity isn't enough anymore. It has no inverter of its own and doesn't connect to the grid: the energy it stores always passes through the control unit it's attached to.
It fixes above or below the existing unit through the dedicated expansion port, and can in turn host other identical modules up to the tower's limit. Anyone starting with just the control unit can add one or more later, as the system grows, without having to dismantle what's already installed.
It works only with the HomePower 2000 Ultra series: before ordering it, it's worth checking you have exactly that control unit, because it isn't built for other lines in the Jackery range.
Highest technical score among the 5 sheets in the Expansion batteries category (room-sized tier): 83/100.

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.
