Architecture describes the product boundary. It is not a system design or an equipment-pairing decision.

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 10 (10/11).

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.

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.

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.

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 correction. Current sonnenBatterie 10/11 sheet, German guarantee, release notes and company ownership rechecked 2026-08-23; unsupported active cell-balancing claim removed. Partial backup disclosure review 2026-10-04: February 2024 battery sheet joins 10/11 (11 kWh nominal, 10 kWh usable) to the currently linked May 2024 sonnenProtect 4000 sheet. Optional accessory required: 4 kW nominal backup at cos phi = 1 and 4.6 kVA overload for 30 minutes on selected single-phase circuits; no motor-start LRA or PV recharging established. Current page current headline differs from sheet and remains unresolved. Purchase agreement and temperature conditions govern; this is not a full product or market re-verification. Terminal-protection explanation integrated 2026-10-05 from DE/AT/CH installation manual 555 version 18, part 1000141 revision 18, 17 July 2025, pages 36/51/99. Mains-line protection is distinct from terminal thermal monitoring; no score, benchmark or full market re-verification.

    US Support Note

    Current text
    The exact "sonnenBatterie 10" name is not listed on sonnen's US products page, checked 9 October 2026. The residential lineup listed there is sonnenHome Battery 11, sonnenCore+ and sonnenEvo. The sonnen Factory Limited Warranty names sonnenCore, sonnenCore+, sonnenEvo and sonnenHome Battery 11 among its covered products and does not name sonnenBatterie 10. sonnen's US pages describe the sonnenHome Battery 11 as developed in the US and as continuing sonnen's series of outdoor storage systems, and do not identify it as the sonnenBatterie 10. This record does not treat it as a rename or regional version of the 10/11. sonnen's US about page states a US-based R&D and manufacturing center in Atlanta, Georgia, and that sonnen has been part of Shell Renewables and Energy Solutions since 2019. The warrantor named in the US warranty is sonnen, Inc., Stone Mountain, GA. None of these pages covers this exact product name.
