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 needs a three-phase supply, so check your switchboard or 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: 9.9kW; How much solar it can turn into usable power at once
Max efficiency: Not on file: we don't have this figure from the manufacturer's documents yet; How much of the solar you make reaches the house
Phases: 3-phase; Needs a three-phase supply, so check your switchboard
Type: Hybrid; Runs solar and a battery from one unit
Warranty: 5yr; How long Shenzhen Sinexcel Isuna Energy Technology Co Ltd stands behind it
