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 one unit in the very big home band. The WA rebate caps at 10 kWh, but that is a rebate limit, not a sizing guide.
