With any solar inverter fault we recommend trying to reboot your solar inverter as the first course of action; it can be that the inverter has developed a glitch and a reboot may solve all your problems! Please ensure you reboot your solar inverter as following these steps in order:

  1. Locate the Solar Supply Main Switch in your switchboard and switch it OFF
  2. Locate the PV ARRAY MAIN SWITCH / SOLAR DC ISOLATOR (usually right beside the inverter) and switch it OFF

The inverter will turn off after a few seconds, wait 30 seconds or so and turn the system back on by turning the switches you just turned off back ON; the order in which you turn them on isn’t important. The inverter will attempt to start up, if after a few minutes the system is back in operation well done!
