    The federal discount, in plain English

    • It comes off the installer's price. There is no form to fill in and no income test.
    • Batteries of 5 to 100 kWh qualify, but only the first 50 kWh of usable capacity earns certificates, and bigger batteries earn less per kWh.
    • The battery must be on the approved list, installed by an SAA-accredited installer, paired with solar, and able to join a virtual power plant. One per electricity meter.
    • It is the same in every state; it does not vary by postcode.
    • It steps down every six months. From 1 Jan to 30 Jun 2027 the factor drops to 5.7.

    South Australia battery rebate questions

    Is there a South Australian battery rebate in 2026?
    There is a REPS payment of up to $2,050 for joining an approved VPP, but funding for most households ran out in May 2026 and it remains open only to priority groups. Everyone gets the federal Cheaper Home Batteries discount.
    Is the SA Home Battery Scheme still open?
    No. It closed in 2022.
    How is the federal battery rebate worked out?
    Usable capacity earns certificates (STCs): the first 14 kWh at the full factor, 14 to 28 kWh at 60%, and 28 to 50 kWh at 15%. For batteries installed 1 May to 31 Dec 2026 the factor is 6.8. A 13.5 kWh battery earns 91 certificates, worth about $3,367 at $37 each. The installer applies it as a discount on the price.
    Is the battery rebate going down?
    Yes. The factor drops every six months. From 1 Jan to 30 Jun 2027 it is 5.7, down from 6.8. Battery prices are also falling, so a lower rebate does not always mean a dearer battery, but the discount itself gets smaller.
