Market position
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.
Blackout protection
82 / 100#5 of 37 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 H10S 17.8 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. The score uses the exact currently documented H10S and B8900M-HA combination; the newer B14400-H is not inferred into this record. Scored model: A10000S with two B8900M-HA modules · checked 2026-07-31. Evidence.

Strong evidence coverage
18 of 18 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.
