The Cheaper Home Batteries Program is the national battery rebate that applies right across South Australia. It’s the biggest single saving on a battery, and it stacks with the SA REPS Virtual Power Plant incentive. Here’s how it works in plain English.
How much is the federal battery rebate?
The rebate is delivered as a discount on the upfront price, worth around $252 per usable kWh of battery for the first 14kWh (as of May 2026, after the 1 May step-down). On common sizes that means roughly:
| Battery size | Approx. federal rebate |
|---|---|
| 5kWh | ~$1,260 |
| 10kWh | ~$2,520 |
| 13.5kWh | ~$3,400 |
Indicative, based on ~$252/usable kWh for the first 14kWh. Figures current as of May 2026 and step down over time.
The tiers – and why bigger isn’t always better
The rebate applies to batteries from 5kWh to 50kWh, but the rate tapers as the battery gets larger:
- 0 to 14kWh – full rate (100%)
- 14 to 28kWh – 60% of the rate
- 28 to 50kWh – 15% of the rate
That’s why 10kWh is such a common choice in SA – it sits inside the full-rate band and matches typical evening usage.
Stacking it with the SA incentives

The federal rebate is automatic on the price – you don’t apply separately, your accredited installer handles it. The SA REPS Virtual Power Plant incentive (up to $2,050) is claimed by connecting your battery to an approved VPP. Together they’re what brings a 10kWh battery down to around $8,000 to $12,000 installed.
What you need to qualify
- A battery between 5kWh and 50kWh from the approved product list.
- Installation by a Clean Energy Council-accredited installer.
- A system that meets the program’s safety and connection standards.
You don’t need to already have solar – the rebate applies to the battery either way – but pairing it with solar is what makes a battery worthwhile.

Federal battery rebate – FAQs
Do I have to apply for the federal rebate myself?
No. The discount is applied at the point of sale by your accredited installer, who handles the paperwork. You just pay the reduced price.
How much is the rebate on a 10kWh battery?
About $2,520, based on roughly $252 per usable kWh for the first 14kWh (as of May 2026). The rate steps down at the start of 2027, so the dollar figure will fall.
Can I combine it with the SA VPP incentive?
Yes. The federal rebate stacks with the SA REPS Virtual Power Plant incentive (up to $2,050), which you unlock by joining an approved VPP. Together they’re worth $4,500+ on a 10kWh battery.
When does the program end?
It runs to 2030, but the rebate rate reduces each year. The earlier you install, the larger the discount.
