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.
Usable capacity sourceDepth-of-discharge source 1Depth-of-discharge source 2Capacity guarantee: minimum retained at year 10
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.
Blackout protection
61 / 100#54 of 90 batteriesPartial (essential loads)
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.
