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 is anchored to the highest published rating in this exact series. Scored model: GW25K-MT (25 kW, three-phase, medium commercial string) · checked 2026-08-23. Evidence.

Sources & references · checked 2026-08-23

Strong evidence coverage

26 of 26 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. GoodWe GW25K-MT exact Australian datasheet and manual, AU/NZ warranty Rev 5.8 dated 24 July 2026, and listed-company evidence rechecked 2026-08-23.
