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.

Before you buy

Two things to check

Local positionUse a market view to check local availability, approvals and warranty scope.

Ask the installer: What usable capacity, backup power and warranted operating conditions will the installed Smile M5 configuration deliver?

Verification & sources

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 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.
