What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Usable capacity
93.75% of this battery’s nominal capacity is usable, 15 kWh in the scored configuration.15 kWh usableScored configuration: aPower X-02-AU (APR-05K15V1-AU).
The remaining 6.25% stays in the pack as reserve; the home never draws it.
Nominal capacity is not stated here. The usable kWh and the depth-of-discharge percentage are sourced separately, at times from different documents and different module counts, so dividing one by the other would produce a nominal figure no manufacturer published.
Usable capacity sourceDepth-of-discharge sourceCapacity guarantee: minimum retained at year 12
No year-by-year capacity schedule is published for this product - the manufacturer guarantees only this end-of-term minimum, not a specific decline curve. Capacity figure based on the sourced usable capacity of the base configuration; modular systems scale with additional modules.

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.
