MARSTEK Jupiter C is an all-in-one system: the 2560 Wh LiFePO4 battery and an integrated microinverter are in the same unit, so no separate inverter is needed.
It has four MPPTs for the panels. Cycle life is over 6000 cycles down to 80% of original capacity, with a depth of discharge of 90%. The ingress protection rating is IP65.

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.
