What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Usable capacity
Stated depth of discharge: 90.9%. Published usable energy: 10 kWh in the scored configuration. These values may have different measurement conditions.10 kWh usableScored configuration: sonnenBatterie Evo.
The stated depth of discharge and published usable energy can have different test conditions or configuration limits. They do not by themselves establish nominal capacity or a reserve that is always inaccessible. Delivered AC energy and runtime also depend on the inverter, settings and loads.
The score uses the exact reviewed reference configuration; larger stacks do not receive a capacity-size advantage.
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.

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.

Rings, outside in: manufacturer claim, certified or regulator-listed, third-party source. The centre is review.solar's own measurement, empty for every product today. Warranty terms and design facts that rest on the maker's own word are counted beside the rings; a reviewed absence, or one that reaches beyond the maker's claim, stays in them.
