Delta Solivia Solar Inverter AC Relay Failure? Try this.

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!

If after rebooting the AC Relay Failure error comes up again you are going to need professional help. This is an error which will be covered under the Delta 10 year warranty; please contact us through the button below and we’ll assist you further.
