Solar repairs and inverter replacement in Tweed
Inverter showing an error, or your bill suddenly jumped? We find the fault, fix it and tell you honestly whether repair or replacement makes sense.
Solar Repairs Tweed
From the river towns around Murwillumbah to the beach suburbs of Kingscliff, Cabarita and Pottsville, the Tweed sits on the NSW side of the border, so it runs on Essential Energy's network and NSW energy rules.
Inverters are the hardest working part of a solar system and most last 10 to 15 years. When one fails, your panels keep sitting in the sun but you get nothing from them. Many Tweed homes also have systems that were installed by companies no longer around.
We test the array, inverter, isolators and wiring, then give you a clear written report. If replacement makes more sense, we will quote a like-for-like inverter or a hybrid inverter that is ready for a battery.

Repairs & upgrades in Tweed: questions
Still unsure? Talk to us directly. You will speak with the people who do the work.
Call 0449 942 735How do I know if my solar system is faulty?
Common signs are an inverter showing a red light or error code, a blank screen during the day, a power bill that jumps without a change in usage, or monitoring that shows zero output on a sunny day.
Do you fix systems you did not install?
Yes. A lot of our repair work in Tweed is on systems from companies that have since closed. We work on all mainstream brands.
Should I repair or replace my inverter?
If the inverter is under warranty, we will help you claim it. If it is over 10 years old and out of warranty, replacing it is usually better value than repairing, and it is a good moment to consider a battery-ready hybrid.
How often should solar panels be checked?
Every two to three years is a good rule, or sooner near the coast where salt air is harder on fixings and isolators.
