Common Inverter Problems We Fix

Solar inverters are the hardest-working component in your system, converting DC power from your panels into usable AC electricity every day. Over time, heat, dust, and electrical stress can cause faults that reduce your generation or shut your system down entirely.

Our CEC-accredited technicians have the diagnostic tools and experience to quickly identify and resolve issues across all major inverter brands. Whether it's a simple error code reset or a component-level repair, we'll get your system back online fast.

  • Error codes and warning lights
  • No power output or reduced generation
  • Tripping safety switches or circuit breakers
  • Overheating and thermal shutdowns
  • Display failures or blank screens
  • Wi-Fi and monitoring connectivity issues
  • Ground fault and isolation errors
  • Fan noise or unusual sounds

Honest Advice

When to Upgrade vs Repair

Not every inverter fault warrants a repair. If your unit is older than 10 years, out of warranty, or uses outdated technology, upgrading to a modern inverter can be more cost-effective in the long run. Newer models from brands like Fronius and Sungrow offer higher efficiency, built-in monitoring, and longer warranties of up to 12 years.

We'll always give you an honest assessment. If a repair makes sense, we'll fix it. If an upgrade will save you more money over time, we'll explain why and provide options that suit your budget and system size.

Common Questions

Inverter Repair FAQs

How do I know if my solar inverter needs repairing?

Common signs include a red or orange warning light on the inverter, error codes on the display, your electricity bills increasing unexpectedly, or your monitoring app showing reduced or zero generation. If your inverter screen is blank or the unit is making unusual buzzing or clicking sounds, it likely needs professional attention.

How long does a typical inverter repair take?

Most inverter repairs are completed within a single visit of 1-3 hours. If a replacement part needs to be ordered or a warranty claim lodged with the manufacturer, we'll keep you informed of the timeline and get your system back online as quickly as possible.

Is it worth repairing an old inverter or should I replace it?

As a general rule, if your inverter is over 10 years old and out of warranty, replacement is usually more cost-effective. Newer inverters are significantly more efficient, offer better monitoring, and come with fresh warranties of 5-12 years. We'll give you an honest recommendation based on your specific situation.

Do you handle inverter warranty claims?

Yes. As CEC-accredited installers, we can manage warranty claims with all major inverter manufacturers including Fronius, SMA, Sungrow, Goodwe, and Enphase. We handle the paperwork, liaise with the manufacturer, and install the replacement unit.

Can you repair any brand of inverter?

We service and repair all major inverter brands sold in Australia, including Fronius, SMA, Sungrow, Goodwe, Enphase, SolarEdge, ABB, Huawei, Growatt, and Delta. Even if your brand isn't listed, get in touch and we'll let you know how we can help.
