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: MID 25KTL3-X (25 kW, three-phase, light commercial string) · checked 2026-06-20. 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. MID 25KTL3-X1-AU exact sheet and official Growatt history rechecked 2026-08-23; battery and backup remain reviewed absences.
