Usable capacity
100% of this battery’s nominal capacity is usable, 14 kWh in the scored configuration.14 kWh usableScored configuration: EK90 HS5-10K-T3-14. Published range 14–54 kWh.
No reserve is withheld at the stated depth of discharge.
At a sourced 100% depth of discharge the usable and nominal figures are the same number, so no separate nominal capacity is stated.
Usable capacity sourceDepth-of-discharge sourceCapacity guarantee: minimum retained at year 15
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
82 / 100#4 of 81 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.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. The 14 kWh reference is scored; the source's later S3/S4 table typo does not create alternative phase identities. Scored model: EK90 HS5-10K-T3-14 · checked 2026-08-26. Evidence.

Strong evidence coverage
25 of 25 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.
