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 5S approval row is held outside the scored family because the reviewed current warranty does not name it. Scored model: HiOne-12S-G3-AU · checked 2026-08-27. Evidence.

Sources & references · checked 2026-09-01

Strong evidence coverage

13 of 13 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. Exact technical and warranty sources plus CER source version dated 20 August 2026, checked 2026-08-27 Inverter operating-envelope refresh 2026-08-31: remaining peak, weighted, oversizing or thermal gaps closed as scoped reviewed absences. First-market US and DE overlay review 2026-09-01: official regional catalogues recorded; Australian overlays and scores unchanged.
