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:
- Locate the Solar Supply Main Switch in your switchboard and switch it OFF
- 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 complete the form above under the URGENT heading and we’ll assist you further.

Hi Ken, thanks for reaching out to us in regards to your Delta Solivia inverter issue.

Today I had “an AC RELAY FAILURE” message on my Delta Solivia 3.3 system Serial No EOE46010260 This system was installed in July 2012 and connected to the Grid on 8 August 2012, so should be under warranty still. Unfortunately the installing Electrician has left the area and moved to Queensland to live, so I cannot get him to attend to it. I have tried quite a few times to reboot it as per the instructions on this website, every time I get the same message on the unit. Please advise me what is the next step to having it repaired or replaced to RECTIFY the problem.
Hi Patrick when you see this message your inverter isn’t working so you should be concerned! I’d be checking that all the isolators and circuit breakers are turned on. Thanks
I have a yellow light on the lowest indicator and panel says AC voltage failure. The system was recently examined and pronounced OK. What is the next step? Should I be concerned?
