Battery Storage Systems in Perth Metropolitan
A guide to choosing a battery storage installer in Perth Metropolitan, what to look for, and how our scoring works. 155 suppliers compared.
Battery storage lets a solar system keep working after the sun goes down. Instead of exporting excess daytime generation to the grid for a few cents a kilowatt-hour, a battery stores that power so a household can use it in the evening peak, or fall back on it during an outage if the system is set up with backup capability. In Perth, where Synergy's feed-in tariffs have dropped and peak evening rates keep climbing, batteries are increasingly what makes a solar investment pay off faster.
We've listed 155 businesses across the Perth Metropolitan area that supply and install battery storage, ranging from small local electricians who add batteries to existing solar arrays through to full-service solar and battery specialists handling design, supply, installation and after-sales service.
What to look for in a supplier
- Proper accreditation to install battery systems and connect them to the grid under Western Power's rules
- Clear advice on sizing: a battery too small won't cover your evening usage, one too large wastes money on capacity you'll rarely use
- Transparent warranty terms on both the battery unit and the installation workmanship
- Honest answers about compatibility with your existing inverter and panels, or whether a hybrid inverter swap is needed
- A written quote that separates equipment, installation and any switchboard or metering upgrades
Our methodology explains exactly how we score each business, based on verified customer feedback, response consistency and other public signals, so you can compare suppliers on more than a star rating alone.

Common questions about battery storage systems
- How much does a home battery storage system cost in Perth?
- Most household batteries installed alongside solar run from around $8,000 to $15,000 fully installed, depending on the battery brand, storage capacity (typically 5kWh to 13.5kWh) and whether a new hybrid inverter is needed. Larger systems or those with backup power capability cost more.
- How often does a battery need replacing or servicing?
- Most home batteries are warrantied for 10 years and are expected to retain a usable capacity through that period, though actual lifespan depends on usage patterns and how deeply the battery is cycled each day. Routine servicing is minimal, but it's worth having the installer check connections and firmware every couple of years.
- What should I expect during a battery installation?
- A typical install takes one to two days: mounting the battery unit (usually in a garage or on an external wall), wiring it into the switchboard, configuring the inverter, and testing the system's ability to charge from solar and discharge to the home. You'll also get a walkthrough of the monitoring app afterwards.
- How can I judge whether a battery installer does quality work?
- Ask to see examples of completed installs, check they hold current electrical and Clean Energy Council accreditation, and look at how they handle warranty claims and follow-up support, not just the upfront sale. Consistent, detailed customer feedback over time is a better signal than a handful of five-star reviews.
