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.

Not established

The exact named path is not established for Australia. This is not a finding that the products cannot be used together.

Single phase · AU · checked 2026-08-02

Evidence boundary: No backup or battery operation should be quoted from this pairing because exact compatibility was not established.

Configuration boundary: The exact MIN XH2 source names APX S0 rather than APX S2.

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?
