Home Battery in Australia: Costs, Rebates & Free Quotes (2026)
A home battery stores the surplus electricity your solar panels make during the day so you can use it at night, instead of exporting it for a few cents and buying it back at full price after dark. With the federal Cheaper Home Batteries Program now reducing upfront costs from mid-2026, batteries have moved from a luxury to a genuinely sensible upgrade for households with solar.
The core appeal is independence: a battery shifts your cheap daytime solar into the expensive evening peak, and many models keep essential circuits running during a blackout. Paired with rooftop solar and a heat pump, a battery is the final piece that takes a home most of the way off the grid.

How it works
A battery charges from your solar (or off-peak grid power) and discharges when your home needs more than the panels are producing — typically in the evening. A hybrid inverter, or a separate battery inverter, manages the flow and decides when to charge, discharge, export or back up. Capacity is measured in usable kilowatt-hours (kWh): a 10kWh battery covers a typical evening for many homes, while 13.5kWh and larger suit bigger households or those wanting blackout cover. Smart models learn your usage and the weather forecast to maximise savings.
Why households switch
- Use your solar after dark. Store midday surplus and run your evening on it, cutting the grid power you buy at peak rates — often the most expensive electricity of the day.
- Cheaper Home Batteries Program. The federal program reduces the upfront cost of an eligible battery from mid-2026, dramatically improving payback compared with buying a battery a year ago.
- Blackout backup. Most batteries can be configured to keep essential circuits — fridge, lights, internet, modem — running through an outage, valuable in storm-prone parts of Victoria.
- Get more from existing solar. If you already export a lot of solar for a low feed-in tariff, a battery captures that value instead of giving it away to the grid.

Home battery FAQs
How much does a home battery cost?
Most batteries cost $6,000–$15,000 installed depending on capacity and backup, before the Cheaper Home Batteries Program discount, which reduces the upfront price from mid-2026.
Is a home battery worth it?
It depends on your tariff and surplus solar. Households with a high evening peak and plenty of daytime export see the best returns; blackout backup adds value in storm-prone areas even where pure payback is longer.
What size battery do I need?
Size it to your evening usage and how much surplus solar you generate. Around 10kWh suits many homes; larger households or those wanting backup go to 13.5kWh or more.
Will a battery power my home in a blackout?
Only if it's configured for backup. Basic installs shut down during an outage; essential-circuit or whole-home backup needs extra hardware, so confirm exactly what's included in your quote.
What battery rebates are available in Victoria?
The federal Cheaper Home Batteries Program reduces upfront cost from mid-2026, and a Solar Victoria interest-free loan may be available. Joining a Virtual Power Plant can add ongoing credits. Verify current terms before committing.
