Decision evidence

What the documents establish

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

Usable capacity

Stated depth of discharge: 100%. Published usable energy: 13.99 kWh in the scored configuration. These values may have different measurement conditions.

13.99 kWh usableScored configuration: SMILE-M5-S-INV with one SMILE-M-BAT-13.9P. Published range 13.99–27.98 kWh.

The stated depth of discharge and published usable energy can have different test conditions or configuration limits. They do not by themselves establish nominal capacity or a reserve that is always inaccessible. Delivered AC energy and runtime also depend on the inverter, settings and loads.

The score uses one current 13.99 kWh battery module, not the largest supported stack.

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 score uses one current 13.99 kWh battery module, not the largest supported stack. Scored model: SMILE-M5-S-INV with one SMILE-M-BAT-13.9P · checked 2026-07-31. Evidence.

Strong evidence coverage

21 of 21 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.

How far the evidence reaches

Rings, outside in: manufacturer claim, certified or regulator-listed, third-party source. The centre is review.solar's own measurement, empty for every product today. Warranty terms and design facts that rest on the maker's own word are counted beside the rings; a reviewed absence, or one that reaches beyond the maker's claim, stays in them.
