What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
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
67 / 100#33 of 78 batteriesPartial (essential loads)
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.

Market context
Global evidencechange in the site menu
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 named reviewed reference configuration, not the largest stack. Scored model: HM6 with two 5.12 kWh modules (10.24 kWh nominal) · checked 2026-07-31. Evidence.
Sources & references · checked 2026-08-02
Strong evidence coverage
14 of 14 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.
