What we can tell you

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

It is a battery inverter: it runs a battery, and pairs with a separate solar inverter.
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: 3kW
Phases Runs on a standard single-phase supply: Single
MPPT trackers 2 roof faces can be tuned independently: 2
Type Runs a battery; pairs with a separate solar inverter: Battery
Warranty How long FOXESS CO LTD stands behind it: 12yr
