Xantrex Solar Inverter Ground Fault Reset System
If your Xantrex solar inverter is displaying a Ground Fault Reset System message it’s a clear sign your solar power system isn’t working. There are two ways to tell you have this error:
- The screen is continually coming up with “Ground Fault Reset System” and then “Inverter Offline”
- The “Ground Fault” light is lit red
This can mean one of two things: either your system has a major issue, or you have a temporary glitch with your system.
When the Ground Fault Reset System message is a problem
Generally if you’re seeing the Ground Fault Reset System message on your Xantrex inverter it’s indicating that the inverter has detected a ground fault with your solar power system. Ground faults are caused when some part of the electrical system comes into contact with the earth. It can be caused by moisture getting somewhere it’s not supposed to or by damage to some part of the system. Either way the ground fault needs immediate attention, but before you call a solar accredited electrician, it may be worth attempting a reboot of your inverter first.
How to Reboot Your Xantrex Solar Inverter
Rebooting your solar inverter is quite simple, however it’s important you follow the procedure correctly to avoid damaging your system. There should be instructions near your inverter on how to reboot your inverter which should be somthing like the following:
- 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
- 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.
The Xantrex inverter will take a couple of minutes to restart. If the green light appears again and the inverter starts working then great! If the red “Ground Fault” light is still glowing red after the system has rebooted and you are still seeing the Ground Fault Reset System message you are going to need to get a local solar accredited electrician to look into the cause of the ground fault.
