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.
