What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Usable capacity
90.9% of this battery’s nominal capacity is usable, 10 kWh in the scored configuration.10 kWh usableScored configuration: sonnenBatterie Evo.
The remaining 9.1% 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.

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 the exact reviewed reference configuration; larger stacks do not receive a capacity-size advantage. Scored model: sonnenBatterie Evo · checked 2026-08-08. Evidence.

Strong evidence coverage
14 of 14 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. Australian Evo datasheet version April 2025, AU/NZ operation manual document 5000611 version 002 dated 28 April 2025, March 2026 Australian manufacturer warranty, and CER exports data as at 29 July 2026
