Inverter faults and error codes
Isolation and earth faults, grid voltage errors, inverters that keep restarting, blank screens and communication faults. We test the whole system, not just the inverter, so the fault doesn’t come back.

Inverter errors, zero generation, tripping isolators or a system that just isn’t producing what it used to. We find the fault, fix it, and it doesn’t matter who installed it.
Isolation and earth faults, grid voltage errors, inverters that keep restarting, blank screens and communication faults. We test the whole system, not just the inverter, so the fault doesn’t come back.
Production that has dropped, or stopped. We check strings, panels, cabling and settings and show you the readings.
Failed or water-damaged rooftop isolators are a common cause of faults in older systems. We replace them to current standards.
Cracked glass, burnt cells, storm or hail damage, and panels that test well below their rating.
Batteries that won’t charge, apps that show nothing, and Wi-Fi or meter communication faults.


Check your monitoring app, look for a tripped solar switch in the switchboard, and note any error code on the inverter. Never open the inverter or touch the DC isolators on the roof.
Yes. Most of the repair work we do is on systems we did not install. We work on all common inverter, panel and battery brands sold in Australia.
We start with a fixed-price visit, so you know the cost before we arrive. If a repair or replacement is needed, we quote it on the spot or send it through the same day, and nothing goes ahead until you approve it.
Most inverter errors are not dangerous, but some point to an earth fault or isolation fault that needs an electrician. Do not open the inverter or touch DC isolators. Take a photo of the screen and send it to us when you book.
Yes. If a panel, inverter or battery has failed under warranty, we test it, document the fault and lodge the claim with the manufacturer for you.
Most solar faults across the Perth metro area are booked within a few business days. Let us know if you have no power or a safety concern and we will prioritise it.
