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: Sigen PV 110M1-AU (110 kW, three-phase, grid-tied C&I string) · checked 2026-08-01. Evidence.

Strong evidence coverage
25 of 25 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. Sigenergy Australian Sigen PV 50-125 kW current datasheet reviewed 2026-08-02. Australian warranty-terms recovery 2026-08-29: structured AU overlay terms recovered or held from the exact governing instrument. First-market DE overlay review 2026-08-31: official German catalogues recorded for the remaining 17 AU+US identities; Australian and United States overlays and scores unchanged.
