Rebates on this battery

WA Battery Scheme: Depends on your inverter
Federal STCs: −$6,943

The WA Battery Scheme (up to $1,300) needs VPP enrolment, and the battery needs to pair with an inverter on Synergy's list. We don't know which inverter you'd pair this with, so we can't say whether it applies. Ask your installer. STCs assume about $39.9 a certificate.

Which size band is your home?

Usable capacity, for one battery system

Smaller home: 10 to 15 kWh
Medium home: 20 to 30 kWh
Big home: 30 to 40 kWh
Very big home: 40+ kWh

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.
