South Australia has the highest rooftop solar penetration in the world and no active state battery rebate. That sounds worse than it is: the federal Cheaper Home Batteries discount is the large one, and it applies in full in SA. Here is exactly what you get.
Scheme factors last reviewed
Most popular home batteries are 10 to 15 kWh usable. Check your battery's datasheet for the usable (not nominal) capacity.

We will send your personalised estimate summary plus a plain-English checklist of what you need to be eligible for the CHBP in 2026.
Since 1 March 2026 the Clean Energy Regulator requires geotagged, timestamped photos of battery labelling and serial numbers on every STC claim, and uses automated checks to reject the ones that fall short. NSW installs move to the mandatory CER (Consumer Energy Resources) Installer Portal from mid-2026 with CSIP-AUS backstop-enabled inverters, and solar panels not certified to IEC 61730:2023 came off the approved list on 1 May. Get the free one-page checklist covering all three, plus CEC approved-product, SAA accreditation, STC assignment and DNSP notification.
One rebate applies in SA:
| Federal CHBP discount | 6.8 STCs per usable kWh for the first 14 kWh, applied by your installer as a point-of-sale discount. Roughly $250 per usable kWh at current certificate prices. |
| South Australian state scheme | None currently active. The SA Home Battery Scheme, which ran from 2018 and offered subsidies through a state administrator, is closed to new applications. Any page still advertising it is out of date. |
South Australia ran the Home Battery Scheme for several years and it did its job: SA now has one of the highest household battery uptakes in the country. The scheme is closed and has not been replaced, so in 2026 South Australian households access the federal Cheaper Home Batteries Program only. If an installer quotes you a South Australian government rebate on top, ask them to name the scheme in writing.
The federal discount is still the biggest single number on the quote. It is not a rebate you apply for and wait on, it is a discount your installer applies at the point of sale through a registered agent, so it comes off the invoice before you pay.
The thing that actually varies in SA is not the rebate, it is the quote. The rebate is set by the scheme and is identical whichever installer you use. Installer margin on the same battery can differ by thousands, so comparing quotes matters more here than in states with a top-up to chase.
Your network operator is SA Power Networks. Your installer submits the grid connection notification, and SA has export limits that can affect how a battery is configured, so raise it during the quote.
Adelaide sits in STC zone 3 (rating 1.382). Inland South Australia falls into zone 2, which earns more certificates on the solar side, so a postcode sharpens the estimate outside the metro area.
