Usable capacity
100% of this battery’s nominal capacity is usable, 18.43 kWh in the scored configuration.18.43 kWh usableScored configuration: eVault MAX 18.5 single cabinet.
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.

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.
