If the above error message appears or there are no lights or display on the inverter, you may need to perform a restart to resolve the issue. The correct way to shut down and restart the GCS PV Solar System is listed below and they should be followed accordingly:

  • Go to inverter and locate the Switch Box (next to inverter – grey in colour with green cover)
  • Turn Off AC Isolator (Inverter)– single switch
  • Turn Off DC Isolator (PV Array) – double switch
  • Go to main fuse box on your home and Turn Off solar main power switch
  • Wait half an hour minimum with your system off
  • Switch system back on in the reverse order

(a) Turn On solar main power switch in the main fuse box
(b) Turn On DC Isolator (PV Array) – double switch
(c) Turn On AC Isolator (Inverter) – single switch

When switches are up they are switched ON. Down is OFF.

Allow the system to reconnect for a few minutes and see if the error messages and/or lights are still faulting. If the fault persists, It can be helpful to perform the reboot a couple of times during the day, once in the morning and once in the afternoon. If the Inverter does not start running again after you’ve tried rebooting, it may be another issue.

If you believe your system is underperforming, you will need to take 3 consecutive readings from your Inverter which will assist us with the initial diagnosis of any problems.  To obtain a system reading, please check the inverter screen which will show the system output as ‘E-Today = 6.8kW h’.

It is important that you get these readings as late in the day as possible so it provides us accurate performance readings.  After you have collected this information, please email them and your contact details to  We will assess these and contact you with instructions within 48 – 72 hours.
