Battery Rebate Eligibility

• Its size is 5 to 100 kWh (nominal), and the Clean Energy Council's approved list includes it.
• Solar Accreditation Australia must accredit the installer, who also needs a battery endorsement.
• Solar panels must be part of the setup, whether new or existing. If a battery charges only from the grid, it doesn't qualify.
• Installation has to happen on or after 1 July 2025, and certificates go to just one battery per home.

The Clean Energy Regulator battery page has the full list.

• With no solar panels at all, a battery can't qualify, because storing grid power alone makes it ineligible.
• If a home already has one, adding another won't earn certificates, because the limit is one per address.
• Installed before 1 July 2025, a battery doesn't count.
• A battery that's under 5 kWh, or that isn't on the approved list, doesn't qualify.

The federal eligibility page sets out the rules.

Yes, but past 14 kWh the rate per extra kWh drops, and once your usable storage goes beyond 50 kWh, nothing more counts. Install by 31 December 2026 and you get roughly $2,720 off 10 kWh, $4,760 off 20 kWh, and $3,640 off 13.5 kWh.

They only add rules where they add money. To get Western Australia's rebate, you must join a virtual power plant through Synergy or Horizon Power; the NSW VPP incentive likewise pays only to members of one. Every other state uses only the federal rules above.
