Market context

Global evidencechange in the site menu

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Benchmark anchor. The score uses the named exact German benchmark; larger stacks, paid states and nearby generations do not transfer evidence. Scored model: Powerwall 3P integrated inverter at 15.4 kW · checked 2026-08-16. Evidence.

Sources & references · checked 2026-09-01

Strong evidence coverage

14 of 14 scored criteria link directly to a published source.

Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.

Record revision. Powerwall 3P German datasheet and warranty effective 19 March 2026, checked 2026-08-16. First-market US overlay review 2026-09-01: official United States catalogues recorded; existing Australian and German overlays and scores unchanged.
