AC-coupled battery
Includes battery-side power conversion and connects on the household AC side.

- Backup boundary
- Installation-specific
Usable capacity
90.9% of this battery’s nominal capacity is usable, 10 kWh in the scored configuration.10 kWh usableScored configuration: sonnenBatterie 10 (10/11).
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 2Depth-of-discharge source 3Capacity 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
44 / 100#79 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. Scored model: sonnenBatterie 10 (10/11) · checked 2026-08-23. Evidence.

Strong evidence coverage
21 of 21 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. Current sonnenBatterie 10/11 sheet, German guarantee, release notes and company ownership rechecked 2026-08-23; unsupported active cell-balancing claim removed.
