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 fixed to 10.0HS-M4. M6-M12 power, backup and integration claims do not transfer to the scored reference. Scored model: Cygni 10.0HS-M4 · checked 2026-08-02. Evidence.

Strong evidence coverage

17 of 17 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.

Help strengthen this record

These are published evidence gaps, not private submissions. A source is reviewed under the same methodology whether it comes from a reader, installer or manufacturer.
