Typical installed price, before rebates
The WA Battery Scheme pays $1,300 on this size when it is installed with a Synergy-approved inverter and enrolled in a VPP. 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 smaller home band. The WA rebate caps at 10 kWh, but that is a rebate limit, not a sizing guide.
