Yinergy Digital Power Technology HI-1P4K-L-Y1

CEC listing: HI-1P4K-L-Y1 (AS4777-2 2020)

A 4 kW single-phase hybrid inverter that is battery-ready.

Installed in Perth, typical: ~$1,900; Estimate for the inverter alone — your quote will vary
Rated power: 4kW; How much solar it can run at once
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 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.
