Market context

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 uses one exact 15 kWh Australian aPower X unit; larger multi-unit aGate systems do not inflate the battery score. Scored model: aPower X-02-AU (APR-05K15V1-AU) · checked 2026-08-02. Evidence.

Strong evidence coverage

20 of 20 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.
