Deye AI-W5.1-10P3-AU-B

CEC listing: AI-W5.1-10P3-AU-B (AS4777-2 2020)

A 10 kW three-phase hybrid inverter that is battery-ready.

Installed in Perth, typical: ~$4,750; Estimate for the inverter alone — your quote will vary
Rated power: 10kW; How much solar it can run at once — a large roof
Battery-ready: Yes; Hybrid: a battery plugs straight in, no second box

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 — check your switchboard, or ask your installer.
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: 10kW
Max efficiency How much of the solar you make reaches the house: 97.6%
Phases Needs a three-phase supply — check your switchboard: 3-phase
Type Runs solar and a battery from one unit: Hybrid
Warranty How long NingBo Deye Inverter Technology Co Ltd stands behind it: 10yr
