Market position
The data
Capacity guarantee: minimum retained at year 12.5
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
78 / 100#8 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 PowerQ EQ4000 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 smallest exact US PowerQ configuration. The 7.16-25.04 kWh displayed range is usable energy rounded to two decimals from the published 7.95-27.82 kWh nominal range at 90% DoD. Scored model: US1H-3.8-EQL2 with EQ4000-AL2 · checked 2026-07-27. Evidence.

Strong evidence coverage
20 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.
