Tesla Powerwall 3, Sigenergy, ESY, Goodwe ESA. Add to an existing solar system or pair with a new install — and claim the federal battery rebate while it lasts.
Without a battery, excess solar generation is exported to the grid for as little as 5c/kWh — while you draw back at night for 28–35c/kWh. A home battery stores that surplus and makes it available when you actually need it.
Our SAA-accredited Master Electricians assess your existing system, usage profile, and budget before recommending a battery. We only install proven brands, and every installation includes blackout protection setup and app configuration.
Federal STC Battery Rebate
Claim around 30% off your battery — before the rebate steps down.
The federal Cheaper Home Batteries Program expanded the Small-scale Renewable Energy Scheme (STCs) to include eligible home batteries from 1 July 2025. For most households, that's thousands of dollars knocked straight off the upfront cost — applied at the point of sale, no paperwork on your end. Around 30% is the headline figure and it holds for a typical home battery, but the scheme is tiered: since 1 May 2026 it pays the full per-kWh rate on the first 14 kWh of usable capacity, 60% of that rate from 14 to 28 kWh, and 15% above that. The underlying rate also steps down through to 2030. We calculate the exact figure for the capacity you install and show it on your quote.

FAQ
Common questions
Can I add a battery to my existing solar system?
Yes — in most cases. We assess your existing inverter and switchboard to confirm compatibility. In some cases a hybrid inverter may need to be installed alongside the battery.
What size battery do I need?
For most households, a 10–14kWh battery covers overnight usage. We size the recommendation based on your actual consumption data, not a rule-of-thumb.
Will a battery work during a blackout?
Most batteries we install include blackout protection as standard. We configure this during installation and confirm it's working before we leave.
What government incentives are available for batteries?
The biggest one is the federal STC Battery Rebate (Cheaper Home Batteries Program), live since 1 July 2025 — typically around 30% off the upfront cost of an eligible install, applied straight to your quote. The battery must be CEC-listed and VPP-capable, and installed by an accredited installer. Around 30% is the headline figure and it holds for a typical home battery, but the scheme is tiered: since 1 May 2026 it pays the full per-kWh rate on the first 14 kWh of usable capacity, 60% of that rate from 14 to 28 kWh, and 15% above that. The underlying rate also steps down through to 2030. We calculate the exact figure for the capacity you install and show it on your quote. It can also be stacked with Victoria's Solar Homes interest-free battery loan, and we handle all the paperwork.
