Usable capacity

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

15 kWh usableScored configuration: SBH150 (three SMR050_S modules; 15.0 kWh usable). Published range 15–40 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.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Benchmark anchor. The Australian range starts at the reviewed SBH150 complete stack. A single 5 kWh SMR050_S module is not presented as a complete scored system. Scored model: SBH150 (three SMR050_S modules; 15.0 kWh usable) · checked 2026-06-16. Evidence.

Strong evidence coverage

27 of 27 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.
