SMA Home Storage 9.8 combines three lithium iron phosphate (LiFePO4) modules in the same tower, 3.28 kWh each. It pairs with both hybrid inverters in SMA's Smart Energy range: the single-phase Sunny Boy Smart Energy, with 1 to 4 modules, and the three-phase Sunny Tripower Smart Energy, with 2 to 5 modules.
It is part of a closed system: it does not pair with the older Sunny Boy Storage or with inverters from other brands. Modules can be added within two years of the first installation, up to 16.4 kWh.

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.
