GoodWe GW3600-SBP-20

CEC listing: GW3600-SBP-20 (AS4777-2 2020)

A 3.7 kW single-phase battery inverter.

Installed in Perth, typical: ~$1,564; Estimate for the inverter alone — your quote will vary
Rated power: 3.7kW; How much solar it can run at once
Battery-ready: Yes; Battery inverter: it runs the battery, alongside your solar inverter

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.
