Solar Inverters & Components in Perth Metropolitan
A guide to the 68 Perth Metropolitan suppliers of solar inverters and components, what to check before buying, and how our rankings can help.
An inverter is the part of a solar system that turns the DC power your panels generate into the AC power your home actually runs on. Get it wrong, or buy from a supplier who can't back it up, and it's usually the first thing to fail or the hardest thing to get serviced. This category covers the 68 businesses across Perth Metropolitan that supply inverters, batteries, mounting hardware, monitoring systems, isolators, and the other components that sit between your panels and your switchboard.
What this covers
Most of these suppliers deal in string inverters, microinverters, hybrid inverters for battery-ready systems, and the racking, cabling, and monitoring gear that goes with them. Some sell direct to installers only, others will quote homeowners and small businesses doing a DIY-adjacent upgrade or a straight replacement of a failed unit. A few carry battery storage lines and the components needed to integrate them with an existing array.
What to check before you buy
Look at what brands a supplier actually stocks and whether those brands have a local service agent in WA, since freight delays on warranty claims for interstate-only stock are common. Ask about the warranty terms on the inverter itself (5 to 12 years is typical) versus the workmanship warranty if they're also installing. Check the unit is on the Clean Energy Council approved products list, which matters for any rebate or STC claim. And ask what happens if the inverter needs replacing under warranty: some suppliers cover labour, most don't past year one or two.

Common questions about solar inverters & components
- How much does a replacement solar inverter cost in Perth?
- A straightforward string inverter swap typically runs from around $1,500 to $3,500 including the unit and installation, depending on system size and brand. Hybrid inverters set up for battery integration cost more, often $3,000 to $6,000 installed.
- How often do solar inverters need replacing?
- Most string inverters are rated to last 10 to 15 years, though many fail earlier in Perth's heat if they're mounted in direct sun or a poorly ventilated spot. Microinverters, being distributed across the roof, tend to have longer individual lifespans but replacing one still means a roof visit.
- What should I expect during a supplier consultation?
- A decent supplier should ask about your existing system size, roof orientation, and whether you're planning to add batteries later, then recommend a compatible inverter rather than just pushing whatever's in stock. Get a written quote that itemises the unit brand and model, not just a lump sum.
- How can I judge the quality of a solar component supplier?
- Check they stock Clean Energy Council approved products, ask how long they've serviced the brands they sell (not just sold them), and look for a track record of resolving warranty issues without you having to chase the manufacturer directly.
