Battery rebates in WA: CEC, Synergy/Horizon, and what to check
In Western Australia, rebate-ready home batteries sit on three layers: (1) the battery must appear on the Clean Energy Council approved batteries list, (2) the inverter/solution must sit on your retailer’s Supported Solutions List (Synergy or Horizon) for VPP participation, and (3) installation must go through a Plenti-accredited vendor under the WA Residential Battery Scheme. Federal Cheaper Home Batteries sits alongside, not instead of, those WA gates. Always verify live listings and dollar amounts on government sources before signing a quote — do not rely on marketing copy alone.
Decision table
| Criterion | CEC approved batteries | Synergy / Horizon SSL | Plenti WA scheme vendor |
|---|---|---|---|
| What it covers | National product safety/quality listing | Retailer VPP / scheme technical pathway | WA rebate / no-interest loan administration |
| Who applies | N/A — product must already be listed | Vendor confirms compatibility | Accredited vendor applies on your behalf |
| Battery requirement | Exact brand/model string on CEC register | Modules CEC-listed; solution on SSL | Scheme-eligible goods via approved vendor |
| Inverter / solution requirement | Inverters have separate CEC lists | Inverter must be on retailer SSL for your network | Vendor ensures compatible package |
| Verify before signing | Search CEC register for exact model | Check live Synergy or Horizon list for your address | Confirm vendor is on Plenti directory |
Federal Cheaper Home Batteries
The federal program reduces upfront cost for eligible CEC-approved home batteries installed by accredited installers. Rates, tiers, and size caps change — treat any dollar figure as date-stamped and verify on Clean Energy Regulator / program pages before quoting.
Federal support does not replace WA scheme rules. A system can be federally eligible and still miss Synergy/Horizon SSL or Plenti vendor requirements.
WA Residential Battery Scheme
The WA scheme is administered with Plenti. Households do not typically lodge the rebate application themselves — an accredited vendor does. Synergy and Horizon customers face different rebate ceilings; confirm current amounts on wa.gov.au.
Expect VPP participation and ongoing internet connectivity requirements. Inverters must appear on the relevant Supported Solutions List; battery modules must be CEC-approved.
Where RENOZ fits
RENOZ publishes modular LV stackable storage engineered in Perth. CEC listing status and any Synergy/Horizon SSL pathway must be confirmed on live official lists before anyone claims “rebate eligible” for a specific RENOZ + inverter package.
Use /resources for datasheets and declarations, and ask RENOZ or a Plenti-accredited partner to confirm the exact CEC model strings and SSL pairs for your quote.
