Solar repairs and inverter replacement in Forest Lake
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.
Why Forest Lake homes choose RS Energy for repairs & upgrades
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 Forest Lake 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. Our repairs & upgrades work in Forest Lake also covers neighbouring Doolandella, Ellen Grove and Heathwood, all within about 2km.

Forest Lake: a local snapshot
Henry Farley built a homestead here in the late 1870s, and in 1881 Michael Durack bought it as part of Archerfield Station. Fire destroyed the house in the 1930s, and during World War II the area held a command post for the Darra ammunition depot. Delfin began building Brisbane's first master planned community here in 1990, launched by Premier Wayne Goss in 1991, with Lendlease taking over in 2001.

Repairs & upgrades in Forest Lake: 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 Forest Lake 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 Forest Lake 4078 and nearby suburbs?
Yes. Forest Lake is part of our Brisbane Southside service area in the Brisbane City Council area, and we regularly work in Doolandella, Ellen Grove, Heathwood, Inala. Call 0449 942 735 or request a quote online and we will reply within 24 hours.
