What about solar systems with battery back up?
Yes, we can supply and install a solar system with battery storage. A battery storage system enables you to use your solar power at night.

My power keeps tripping, what can I do?
The first step is to isolate the circuit that is causing the problem.
- Unplug all of your appliances from the sockets (don’t just turn off, unplug).
- When everything is unplugged then try to reset the safety switch.
- If the safety switch resets and power is then restored, one by one, start to plug your appliances back in.
- The faulty appliance will trip the safety switch again.
Remember to check grey water pumps, power boards and outdoor power points.
Some outdoor power points can get wet or have a pest infestation that can cause the issue. If you still cannot rectify the situation, then give us a call.
Do you replace old air conditioners?
Yes. We can decommission the old unit, retrieve the gas and dispose of the old unit using good environmental practices and install a new air conditioner unit for you.
Do the solar systems have a warranty?
Yes. The inverters we use have a minimum of 5 years warranty. You can register the inverter online for more warranty. The panels have a 25 year linear power output warranty and a 12 year enhanced product warranty on materials and workmanship.
We guarantee our installation is to current Australian Standards and is of the highest quality workmanship.
You can be assured that any materials or products supplied to you are of a quality standard. We only supply and recommend reputable products from Electrical Wholesalers.
How much electricity will my solar system produce?
It depends on the size of the system. Generally our solar systems generate approx 4.5kw hours per kilowatt of panels per day. eg: A 6.6kw system will generate on average 29.7kwh per day.
Can I add more panels to my system later?
Yes, as long as the system does not go over the approved size from Energex / Ergon. You may choose to install a small system and gradually build your system up over time to the maximum approved size.
Should I add my solar system to my house insurance?
Yes. We recommend you contact your insurer once the solar system is installed and add it to your insurance.
