Home battery storage in Perth
A battery storage system holds the surplus power your rooftop panels generate during the day so you can use it in the evening, when Perth households draw the most and export tariffs are low. Suppliers in this category sell and install lithium iron phosphate (LFP) batteries, hybrid or battery-ready inverters, and the backup circuits that go with them. Some also retrofit batteries to existing solar.
We list businesses across Perth Metropolitan. When comparing them, check these points:
Clean Energy Council accredited installers, and batteries on the approved product list.
Usable capacity (kWh), continuous power output (kW) and warranty terms, including throughput or cycle limits.
Whether the system works as backup in an outage, or only shifts power while the grid is up.
Compatibility with your current inverter and your Western Power connection limits.
A written quote that itemises hardware, installation and any switchboard upgrades.
Our scoring weighs these factors alongside customer feedback, so you can shortlist quickly. See the ranked battery storage guide for the top picks, and read how we score to see what goes into each result.

Common questions about battery storage systems
- How much does a home battery cost in Perth?
- Most installed home batteries run from about $8,000 to $18,000 depending on capacity (commonly 5 to 15 kWh), brand and wiring work. Federal and state incentives, where available, can lower the upfront price, so ask each installer to show the figure after rebates.
- How long does a home battery last?
- Most LFP batteries carry 10-year warranties and are expected to last 10 to 15 years. Warranties usually guarantee a minimum remaining capacity (often 60 to 70 percent) or a total energy throughput, so read those terms closely.
- What happens during installation?
- An accredited installer inspects your switchboard and solar setup, then mounts the battery (often in a garage or on an external wall) and connects it to your inverter. A standard install usually takes one to two days, followed by grid approval and commissioning.
- Will a battery power my house in a blackout?
- Only if it is installed with backup capability. Many systems shut down when the grid fails unless wired with a dedicated backup circuit. Ask which appliances will run and for how long.
