Why a battery
Use your own solar after the sun goes down.
- Lower evening bills. Most daytime solar is exported for a few cents. A battery keeps it for the evening peak.
- Blackout backup. Selected systems keep nominated circuits running during an outage.
- Add to existing solar. Retrofit batteries and hybrid inverter upgrades for older systems.
- VPP and EV ready. Set up for Synergy’s VPP and designed with future EV charging in mind.

FAQ
Home battery questions
How much is the battery rebate in Perth?
For Synergy customers, the WA Residential Battery Scheme pays $130 per kWh of usable capacity, up to $1,300. The Federal Cheaper Home Batteries Program is applied on top. For a 10kWh battery installed between May and December 2026 the two together come to roughly $4,000. Your proposal shows the exact figures line by line.
Do I have to join a Virtual Power Plant?
Yes, to receive the WA rebate. You join your retailer's VPP, which for most Perth homes is Synergy. You can install a battery without joining a VPP, but the WA rebate is not paid. We explain the VPP terms in plain language before you sign.
Can I add a battery to my existing solar?
Usually, yes. We check your existing inverter, switchboard and system age, then recommend either a retrofit battery or a new hybrid inverter if your current one is not compatible.
What size battery do I need?
Most Perth homes we quote land between 10 and 20kWh. We size it from your usage and bills, not from the rebate. Because the federal discount tapers above 14kWh, a bigger battery only makes sense if you use a lot of power at night, such as air conditioning, a pool pump or an EV.
Will a battery keep my power on in a blackout?
Selected systems can keep nominated circuits, such as the fridge, lights and internet, running during an outage. Backup needs to be designed in from the start, so tell us if it matters to you.
Is there finance for batteries?
Yes. Households with a combined income under $210,000 can apply for a no-interest loan of up to $10,000 through the WA scheme, repaid over up to 10 years. We are an approved vendor, and Plenti finance is also available.
