Issues with Isolation Fault messages on Eversolar Solar Inverters are something we have seen a number of times here at SAE Group.
When there is an isolation fault issue with your Eversolar inverter the red alarm light will be lit and the green run light beside it will be off. In normal operating conditions the green light would be solidly lit if the inverter was producing power. The Isolation Fault message means that the inverter has detected an isolation fault: this could be an internal fault with the inverter or a fault with the solar system cables or wiring.
An Eversolar inverter working properly should display a green light and should not have the red light lit.
If you are experiencing this issue in your Eversolar solar inverter you’ll need to do something about it ASAP as your inverter is currently not working.
Troubleshooting an Eversolar solar inverter Relay Check Fail
If this happens to your Eversolar solar inverter the best thing to do is to try rebooting the system to see if this clears the issue by following the shutdown procedure below.
- Turn off the SOLAR SUPPLY MAIN SWITCH located at your switchboard or the Inverter AC Isolator.
- Turn off the PV Array DC Isolator located at the inverter.
- Wait for approximately 1 minute.
- Turn on the AC Isolator and / or Solar Supply Main Switch.
- Turn on the PV ARRAY DC Isolator.
- See if the inverter successfully starts up after the reboot.
If after the reboot the inverter Relay Check Fail error message continues you will need to have a solar accredited electrician replace your inverter.
If the inverter is still within the 5-year warranty period and you have proof of purchase documentation then Eversolar should cover this issue under warranty. If you wish to take this option, you will need to provide proof of purchase of when it was originally installed and the inverter model number and serial number; you can find these details on the side of the inverter.
Just take note though that Eversolar tends to take a while to service warranty claims, usually you will be waiting a month or so.
If your inverter is out of warranty or you’re not prepared to wait for the unit to get fixed, the best thing to do is to have the inverter replaced with a good quality new unit with a full factory warranty.
