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.

Integrated system

BW-INV-TPH10K with BW-BAT-4.8S

Confirmed pairing

The exact named integrated system is recorded as confirmed for Australia.

Three phase · AU · checked 2026-08-02

Backup: The inverter has a dedicated backup port; backed-up circuits and protection remain installation-specific.

Configuration boundary: Bytewatt names BW-BAT-4.8S with BW-INV-TPH10K; the scored reference uses two modules and the published family permits one to six in series.

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 Three Phase 10 configuration deliver?

Market context

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 a two-module 9.2 kWh usable reference configuration rather than rewarding the largest supported six-module stack. Scored model: BW-INV-TPH10K with two BW-BAT-4.8S modules · checked 2026-08-01. Evidence.

Australian warranty decision

1 product record

Read the Australian warranty as a claim pathway: the headline term is separate from remedy, labour, freight, site work, transfer and registration conditions.
