This battery is AC-coupled. To get the WA rebate, the interest-free loan, VPP payments or DEBS export credits, it needs a gateway device from Synergy's approved list (for example SMA or Redback), or an inverter and battery from the same brand (Sungrow or Fronius). Without one, exports are capped at 1.5kW.
Some third-party gateways struggle to pass compliance testing, and adding anything to an AC-coupled system later means the whole system has to be re-checked. For many homes, switching to a hybrid (DC-coupled) inverter is the simpler path. AC vs DC coupling
CSIP-AUS compliant
Inverter must be CSIP-AUS compliant under the current WA framework.
Synergy SSL approved inverter
Needs pairing with a Synergy SSL approved inverter.
VPP activation ready
VPP activation requires a Synergy SSL approved inverter.
WA Battery Scheme rebate
Requires Battery Rewards participation under the current WA framework.
Synergy Battery Rewards
Requires a CSIP-AUS compliant system and reliable internet.
Interest-free loan
Not eligible for interest-free financing.
Under current WA rules, new rebate applications require VPP enrolment and CSIP-AUS compliance. How the scheme works · Estimate VPP earnings

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 sits between the smaller home and medium home bands. The WA rebate caps at 10 kWh, but that is a rebate limit, not a sizing guide.
