No year-by-year capacity schedule is published for this product - the manufacturer guarantees only this end-of-term minimum, not a specific decline curve. Capacity figure based on the sourced usable capacity of the base configuration; modular systems scale with additional modules.

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.

Evidence state

Exact pairing not recorded

Exact pairing not recorded

No exact manufacturer-named inverter, battery or integrated-system pairing is recorded for Australia. This is a documentation state, not a finding that the product cannot be used in a system.

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 Home Storage configuration deliver?

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 the documented five-module 16.4 kWh configuration and publishes the full 3.28-16.4 kWh family range. Inverter-dependent power and backup are not assigned to the battery. Scored model: five HS-BM-3.28-10 modules · checked 2026-08-02. Evidence.
