Usable capacity

100% of this battery’s nominal capacity is usable, 10 kWh in the scored configuration.

10 kWh usableScored configuration: APX 10.0P-S2 AU (two APX 5.0P-B1 modules). Published range 5–30 kWh.

No reserve is withheld at the stated depth of discharge.

At a sourced 100% depth of discharge the usable and nominal figures are the same number, so no separate nominal capacity is stated.

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.

The blackout score is a standalone benchmark of outage resilience only - it re-weights sourced specs already scored in this product’s pillars (backup tier, switchover, surge strength, backup power, off-grid recharge) and never affects the overall score. Dots show the full battery fleet; the marker is this product.

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. Capacity range describes supported configurations; the score remains anchored to the named reviewed reference configuration, not the largest stack. Scored model: APX 10.0P-S2 AU (two APX 5.0P-B1 modules) · checked 2026-07-31. Evidence.

Strong evidence coverage

15 of 15 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. APX HV Battery S2 AU datasheet 202603 and AU 10-year warranty. 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.
