1300 138 591Solar and a battery: use your own solar after dark
Panels make power through the day. A battery stores what you don’t use and runs your home in the evening, when you’d otherwise buy power at full price. We design both around your power bill.
Who solar and a battery suits best
A battery makes the most sense when you use a lot of power after the sun goes down.
Busy evenings
Cooking, washing, air-con and TV after work. A battery covers it with your own daytime solar.
Families at home
Bigger households that use power all day and into the night.
Rising power bills
Less power bought from the grid means less exposure to price rises.
Blackout backup
Essential circuits can keep running in an outage when the system is set up for backup. We explain what yours will cover.
Low feed-in tariffs
Store your spare solar instead of exporting it for a few cents.
Planning an EV
Start with solar and a battery now, add EV charging when you need it.

Your home stays connected. A battery cuts how much power you buy. Going fully off-grid needs a separate design.
Solar and battery questions
What size battery do I need?
It depends on how much power you use after dark. We work it out from your power bill at your free Energy Assessment.
Can I add a battery to my existing solar?
In most cases, yes. We check your inverter and system first. See our Add a battery page.
Will a battery keep my power on in a blackout?
Only if the system is set up for backup. Not every battery does this automatically. We explain what your setup will cover before you buy.
How long does a battery last?
Most home batteries carry manufacturer warranties of around 10 years. We go through the warranty on the battery we recommend.
Is there a rebate on batteries?
Yes. The federal Cheaper Home Batteries discount is taken off your price. It steps down on 1 January 2027.
