sonnenBatterie 10 performance is a residential storage unit with lithium iron phosphate cells and a three-phase grid connection. Nominal capacity ranges from 11 to 55 kWh depending on the number of battery modules. The warranty is 10 years or 10,000 charge cycles on all components, with at least 80% of capacity after 10 years. Backup power is not included: the three-phase whole-home solution is an optional accessory.

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.
