Architecture describes the product boundary. It is not a system design or an equipment-pairing decision.

Usable capacity

100% of this battery’s nominal capacity is usable, 15 kWh in the scored configuration.

15 kWh usableScored configuration: aPower 2 (APR-10K15V2-US).

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.

Strong evidence coverage

25 of 25 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.

    AU Support Note

    Before
    The benchmarked aPower 2 SKU is APR-10K15V2-US. FranklinWH's Australia product page identifies a different model, aPower X (APR-05K15V1-AU), as the only aPower currently available in Australia.
    After
    The benchmarked aPower 2 SKU remains APR-10K15V2-US. FranklinWH's Australia product page still identifies aPower X (APR-05K15V1) as the current Australian aPower. The 29 August 2026 CER battery export has no aPower 2 or APR-10K15V2-US row; aPower X-01-AU and aPower X-02-AU are different identities and are not transferred.
