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.
System decision
Australian system fit
Only exact, manufacturer-named Australian paths are shown. A shared brand, product family or output rating is not proof of compatibility.
A documented relation does not establish site sizing, network approval, protected-load design, firmware state or installer acceptance. When no exact relation is recorded, compatibility remains unestablished in this catalogue.
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 APX HV S2 configuration deliver?
