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, 14.59 kWh in the scored configuration.

14.59 kWh usableScored configuration: Cygni 10.0HS-M4. Published range 7.3–43.77 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.

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 is fixed to 10.0HS-M4. M6-M12 power, backup and integration claims do not transfer to the scored reference. Scored model: Cygni 10.0HS-M4 · checked 2026-08-02. Evidence.

Strong evidence coverage

18 of 18 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.
