Common questions

Frequently Asked Questions About Solar Inverter Repair in Perth

If you are replacing your inverter and considering a full system upgrade, keep in mind that the federal STC solar rebate reduces each year. The Clean Energy Regulator administers the STC scheme. Call 1300 717 583 for current pricing and rebate information.

Why is my solar inverter not working in Perth?

Common causes in Perth include grid overvoltage events on the Western Power network (particularly common in suburban areas during low-demand periods), configuration errors, DC isolator faults, component wear, and internal hardware failure. Perth's extreme summer heat can also cause thermal protection shutdowns. A structured diagnostic inspection is required to confirm the specific cause before any repair or replacement is carried out.

How long do solar inverters last in Perth's climate?

Most solar inverters last 8–12 years in Perth conditions. Inverters installed in poorly ventilated locations, such as garages without airflow or on west-facing walls in full afternoon sun, tend to fail earlier due to heat stress. Premium inverters with adequate ventilation and regular firmware updates can last 15+ years. If your inverter is over 10 years old and experiencing faults, replacement may be more practical than repair.

Is it worth repairing a solar inverter or should I replace it?

It depends on the fault type and inverter age. If your inverter is within its warranty period, we recommend a warranty claim first. For inverters under 8 years old with minor faults, repair is usually more economical. For inverters over 10 years old with major hardware faults, replacement with a modern unit often makes more financial sense, particularly given improvements in inverter efficiency and the ability to add battery storage compatibility. We give you an honest assessment after diagnosis, not a default "replace everything" recommendation.

Does Perth's Western Power grid cause solar inverter shutdowns?

Yes. Perth's high solar penetration rate means the Western Power grid can experience elevated voltage during the middle of the day when many systems are exporting simultaneously. When grid voltage exceeds the inverter's maximum operating threshold, the inverter shuts down as a safety measure. This is a known issue in Perth's eastern and southern suburbs. Our diagnostics distinguish between grid-related shutdowns and inverter hardware faults, so the right corrective action is taken.

What inverter brands do Ares Energy repair and replace in Perth?

We work with all major inverter brands commonly installed in Perth, including SolarEdge, Fronius, SMA, Enphase, Sungrow, Goodwe, and others. For warranty claims, we are experienced with the major brand warranty procedures and can manage the process on your behalf. Contact us on 1300 717 583 to discuss your specific inverter brand and fault.

Can a new inverter allow me to add battery storage to my Perth system?

Yes. If your current inverter is at end-of-life and you're considering battery storage, replacing it with a hybrid inverter simultaneously can be a cost-effective approach. Hybrid inverters support both solar generation and battery storage, allowing you to store excess solar energy for evening use, maximising your self-consumption and reducing what you export at Synergy's lower off-peak DEBS rate. We assess your system's suitability and discuss options during our consultation.
