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.

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.

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 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

19 of 19 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. FranklinWH Australia aPower X system datasheet dated 2026-06-24 and Australia limited warranty effective June 2026. First-market DE overlay review 2026-08-31: official German catalogues recorded for the remaining 17 AU+US identities; Australian and United States overlays and scores unchanged.
