What we can tell you

Read from the figures on this page. No review written yet.

It is a hybrid inverter: solar and a battery run from the one unit, so adding a battery later doesn't need a second box.
It runs on a standard single-phase supply.
We can't confirm it is on Synergy's approved list — a battery paired with it needs that for the WA Battery Scheme, so ask your installer.
It is CEC-approved, which a new install needs to qualify for STCs.

Key specs, in plain terms

The numbers that matter for a home. The full datasheet is below.

Rated power How much solar it can turn into usable power at once: 5kW
Max efficiency How much of the solar you make reaches the house: 97.2%
Phases Runs on a standard single-phase supply: Single
Type Runs solar and a battery from one unit: Hybrid

WA compliance

Synergy approved list: Not confirmed
ESM compliant: Check

Western Power approval is required for every grid-connected install. Under Emergency Solar Management, a new system must be remotely manageable, or take an export limit instead — ask your installer to confirm this inverter’s ESM status.
