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, 5 kWh in the scored configuration.5 kWh usableScored configuration: Smart Battery S0 5 kWh. Published range 5–30 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 source 1Depth-of-discharge source 2Capacity 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. Capacity figure based on the sourced usable capacity of the base configuration; modular systems scale with additional modules.
Blackout protection
64 / 100#50 of 90 batteriesWhole-home (via hybrid inverter)
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. The range uses one to three 5 kWh modules per system and up to two systems. The score remains anchored to one reviewed 5 kWh configuration. Scored model: Smart Battery S0 5 kWh · checked 2026-07-27. Evidence.
Sources & references · checked 2026-08-30
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.
Record revision. Smart Battery S0 May 2025 technical specification, March 2026 warranty, CER battery export and ABR certificate-holder status reviewed 2026-08-07. First-market US and DE overlay review 2026-08-30: official regional catalogues recorded; Australian overlays and scores unchanged.
