How the battery rebate works
The Cheaper Home Batteries Program discounts the upfront cost of an eligible battery by issuing certificates against its usable capacity. Since 1 May 2026 the rate tapers as the battery gets bigger, so the strongest value is in the first 14 kWh — enough to cover most family homes' overnight needs.

Frequently asked questions
What is the federal battery rebate?
The Cheaper Home Batteries Program gives households roughly a 30% discount on the cost of installing an eligible home battery (5–100 kWh). The discount is delivered through Small-scale Technology Certificates and is usually applied upfront by your installer.
How much is the battery rebate per kWh?
From 1 May 2026 the rebate is tiered: about $252 per usable kWh for the first 14 kWh, 60% of that (≈$151) from 14–28 kWh, and 15% (≈$38) from 28–50 kWh. Usable capacity above 50 kWh receives no extra rebate.
Why did the battery rebate change in May 2026?
The program was overhauled to stretch funding further: the full rate now applies only to the first 14 kWh, with larger batteries receiving a reduced top-up. This rewards right-sized batteries while still supporting bigger systems.
Can I get a state battery rebate too?
Often yes. Several states and territories run their own battery rebates or interest-free loans on top of the federal rebate. These change frequently, so we link you to your state's official scheme rather than estimate a figure that may be out of date.
Are these numbers accurate?
The federal per-kWh rates are taken from the published Cheaper Home Batteries Program and date-stamped on the calculator. Results are estimates, not quotes — your final rebate depends on the certified usable capacity and the certificate price at installation.
