Solar repairs and inverter replacement in Sunnybank
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 Sunnybank: local, honest, done right
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 Sunnybank 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.
Brisbane's southside covers older post-war suburbs like Annerley, Moorooka and Holland Park, the busy family areas around Sunnybank, Mansfield and Carindale, and newer pockets at Pallara and Forest Lake. We look after Sunnybank and the surrounding suburbs of Robertson, Coopers Plains and MacGregor, so a free on-site measure in 4109 is easy to book.

About Sunnybank
Jagera people lived across this land for over 20,000 years. The railway pushed through from Yeerongpilly in 1885, and the town was surveyed the next year, with lots selling in 1887. The name comes from the Gillespie family's Sunny Brae Estate, brae being Scots for bank. A popular gardens and swimming pool complex drew visitors from 1938 until it shut in 1989.

Repairs & upgrades in Sunnybank: 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 Sunnybank 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.
Do you service Sunnybank 4109 and nearby suburbs?
Yes. Sunnybank is part of our Brisbane Southside service area in the Brisbane City Council area, and we regularly work in Robertson, Coopers Plains, MacGregor, Sunnybank Hills. Call 0449 942 735 or request a quote online and we will reply within 24 hours.
