The assessment
How it scores, by category
The data
Capacity 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
86 / 100#2 of 32 batteriesWhole-home, seamless (<20ms)
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.
Two things to check
Ask the installer: What usable capacity, backup power and warranted operating conditions will the installed SigenStor configuration deliver?

Market context
Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. Capacity range describes supported configurations; the score remains anchored to the reviewed reference configuration, not the largest stack. Scored model: SigenStor (BAT 8.0 module, stackable) · checked 2026-07-15. Evidence.

Strong evidence coverage
19 of 31 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.
