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

Benchmark anchor. The scored reference is the exact single-phase H2 and B2 combination, not HS2. Warranty retention and backup scope remain withheld. Scored model: H2-6K-S2 + B2-10.0-HV5 · checked 2026-08-02. Evidence.

Strong evidence coverage

12 of 12 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.

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.
