The E3/DC S10 X Compact is an all-in-one storage system with lithium iron phosphate cells, available with 8.25 or 11.2 kWh of usable capacity. It is connected to the grid in three-phase and can also charge the battery from the grid.
In a blackout it forms an isolated three-phase network.

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.
