WA Battery Scheme eligibility

Conditional

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

AC-coupled system: needs a gateway device on the Synergy SSL (e.g. SMA, Redback) for full eligibility, or a same-brand inverter + battery pair (Sungrow or Fronius) for shared compliance. Without one, export is limited to 1.5kW and VPP/DEBS/rebate/loan are unavailable. 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
