SolaX Isolation Fault
Is your SolaX Solar Inverter showing an Isolation Fault message?
When your SolaX solar inverter is operating correctly the inverter light will be a solid green. When the light is red it indicates that your inverter has detected a fault with the system – the particular fault details are displayed on the screen, and if you’re reading this I bet you’re seeing an Isolation Fault message.
SolaX Isolation Fault Message – What does it mean?
An Isolation Fault message on your SolaX inverter is telling you that the system has detected leakage of electricity to earth, and this condition is called an earth fault or an isolation fault. The following list is some of the common causes of SolaX isolation faults that would make a SolaX solar inverter display an Isolation Fault message:
- Moisture ingress in the solar panels
- Moisture ingress in the cabling, plugs, isolators, or inverter
- Damage to cables in the solar power system
If you’re seeing a SolaX Isolation Fault message the first thing we recommend you try is a reboot of your solar power system.
Rebooting Your SolaX Solar Inverter
It is possible that the error you’re seeing with your SolaX inverter is just a glitch which will be fixed by a system reboot. To reboot your SolaX solar inverter please follow these steps:
- Turn OFF the solar supply main switch (or inverter AC isolator if present).
- Turn OFF the PV array DC isolator.
- Wait for the inverter screen to go completely blank and the red fault light to turn off.
- Turn ON the PV array DC isolator.
- Turn ON the solar supply main switch (or inverter AC isolator if present).
- Wait a few minutes while the inverter boots back up.
If immediately after restarting the inverter you still see the error message “Isolation Fault” unfortunately it appears you may have an issue with your system which is going to require professional help. We recommend you get in touch with a local solar accredited electrician to carry out some fault findings on your system and advise you further. If you are in South East QLD somewhere near the Gold Coast or Brisbane area we can help.

Hi Dale, if your SolaX inverter has a relay fault the inverter will need to be replaced. Thanks
