What we can tell you

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

It is a solar-only inverter: adding a battery later means a second inverter or an AC-coupled battery.
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.
The register doesn't currently list it as 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: 33kW
Max efficiency How much of the solar you make reaches the house: 98.8%
Phases Runs on a standard single-phase supply: Single
MPPT trackers 3 roof faces can be tuned independently: 3
Type Runs solar only: Solar
Warranty How long Shenzhen SOFARSOLAR Co Ltd stands behind it: 10yr
