Home batteries in Perth cost from $6,990 fully installed after the federal Cheaper Home Batteries discount (2026). With Synergy charging peak rates while DEBS pays just 2c–10cfor exports, a correctly sized battery now pays for itself in 4–6 years. We install every major brand — compared honestly, side by side.
Why a battery now
Your energy needs don’t follow the sun.
Solar produces through the middle of the day, which is when most homes are empty. Demand arrives after dark, when the array has stopped and the grid is at its most expensive. A battery moves your own cheap daytime energy across that gap.
Your peak is after dark
Most households draw the most power once the sun is down — exactly when the array has stopped producing and grid rates are highest.
Surplus is worth more stored than sold
Exporting off-peak earns 2c a unit under DEBS. The same unit used at night displaces electricity you would otherwise buy.
The lights stay on
A backup-capable battery keeps essential circuits running through an outage, which matters on the semi-rural edges of the network.
Bankable brands
Every major brand, installed locally.
The home-battery brands we install are warranty-backed and eligible for the federal discount. Here is what we stand behind.
