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.

Limited evidence coverage

3 of 27 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.

These are published evidence gaps, not private submissions. A source is reviewed under the same methodology whether it comes from a reader, installer or manufacturer.
