Swatten SiH-14.9kW-TH

CEC listing: SiH-14.9kW-TH (AS4777-2 2020)

A 15 kW three-phase hybrid inverter that is battery-ready.

Installed in Perth, typical: ~$7,125; Estimate for the inverter alone — your quote will vary
Rated power: 15kW; 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
