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.
Its CEC approval has expired, so a new install with it wouldn't qualify for STCs.
We hold no captured datasheet for this model yet, so the specs below come from the CEC register only.

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.
