Decision evidence

What the documents establish

Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.

Usable capacity

100% of this battery’s nominal capacity is usable, 10 kWh in the scored configuration.

10 kWh usableScored configuration: ALP 10.0L-E1. Published range 5–50 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.

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.

Benchmark anchor. The range describes current E1 configurations. The score is anchored to the 10 kWh reference configuration, not the largest parallel system. Scored model: ALP 10.0L-E1 · checked 2026-08-05. Evidence.

Strong evidence coverage

29 of 29 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.
