Typical installed price, before rebates
The WA Battery Scheme (up to $1,300) needs a Synergy-approved inverter and VPP enrolment. We don't know which inverter you'd pair this with, so it isn't deducted above — ask your installer. STCs assume about $39.9 a certificate. Estimates only; your quote will vary.
Usable capacity, for one battery system
This battery is below the smaller-home band. The WA rebate caps at 10 kWh, but that is a rebate limit, not a sizing guide.
