Decision evidence

What the documents establish

Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.

Usable capacity

95% of this battery’s nominal capacity is usable, 9.6 kWh in the scored configuration.

9.6 kWh usableScored configuration: SMILE-G3-S5 with one SMILE-G3-BAT-10.1P. Published range 9.6–57.6 kWh.

The remaining 5% 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.

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 score uses one BAT-10.1P at 9.6 kWh usable; the published range describes one to six matching modules. Scored model: SMILE-G3-S5 with one SMILE-G3-BAT-10.1P · checked 2026-08-01. Evidence.

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.

Record revision. AlphaESS Australia 2026 brochure, exact BAT-10.1P datasheet and 11 October 2024 AU warranty, rechecked 2026-08-01. Australian warranty-terms recovery 2026-08-29: structured AU overlay terms recovered or held from the exact governing instrument. First-market US and DE overlay review 2026-09-01: official regional catalogues recorded; Australian overlays and scores unchanged.
