WA Battery Scheme eligibility

Not eligible

Synergy SSL inverter pairing, VPP participation and state-rebate qualification for this battery. Rebate and STC amounts are shown in the pricing panel.

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

What it costs in Perth

We price batteries by size rather than by model. The average installed price before rebates:

10 kWh: $7,000–$9,000
20 kWh: $10,000–$15,000

Solar Battery Perth’s estimate, Oct 2026. Other sizes are not priced here, and a quote prices this model.

Rebates on this battery

WA Battery Scheme: $0
Federal STCs: $0

The WA rebate is $0 here: it's under the scheme's 5 kWh minimum size. Federal STCs are $0 here: this battery is below the size where the program issues certificates.
