What is the Cheaper Home Batteries Program?
The federal Cheaper Home Batteries program is a $7.2 billion initiative providing approximately $300 per kWh (~30% off) on eligible home battery systems. It is available to all Australian homeowners with solar when using a SAA-accredited installer.
From May 1, 2026, tiered rebates reduce benefits for batteries over 14 kWh. Installing before this date locks in higher rebates for larger systems.

SA Battery Rebate FAQ
helpWhat is the solar battery rebate in South Australia for 2026?
SA homeowners can stack the federal Cheaper Home Batteries rebate (approximately $3,300 for 10kWh) with the REPS VPP incentive (up to $2,050). That is $5,050+ off your battery installation, one of the best deals in Australia.
helpWhat is the REPS VPP rebate in South Australia?
The Retailer Energy Productivity Scheme (REPS) provides rebates of up to $2,050 when you connect your battery to an approved Virtual Power Plant. Participating providers include AGL, Origin, Tesla, and others. The VPP allows your battery to support the grid during peak demand in exchange for the rebate.
helpCan I stack the SA VPP rebate with the federal battery rebate?
Yes. The REPS VPP rebate and the federal Cheaper Home Batteries rebate are fully stackable. A typical 10kWh battery could receive $3,300 federal + $2,050 REPS = $5,050+ total savings.
helpDo I have to join a VPP to get the SA battery rebate?
You do not need to join a VPP to get the federal rebate of approximately $3,300. However, the additional REPS incentive of up to $2,050 requires VPP enrolment. Most VPP programs have minimal impact on your daily battery usage.
helpHow much does a battery cost in SA after all rebates?
With both the federal and REPS rebates, a 13.5kWh Tesla Powerwall 3 could cost as little as $5,650 (down from $11,000). A 10kWh system could drop to around $5,950. These are among the lowest battery prices in Australia thanks to SA's generous stacking.
