A GridVolt10MFault on your Solax Inverter indicates a grid overvoltage for ten minutes fault. The system will reconnect when the utility is back to normal.
What causes GridVoltFault on Solax X3-PRO G2 and how to fix it?
A GridVoltFault on your Solax Inverter means the grid voltage is out of the acceptable range. You can try checking if the mains cable is loose. Also, the system is designed to automatically reconnect once the utility voltage returns to normal.
Why is my Solax X3-PRO G2 showing OverTempFault?
An OverTempFault on your Solax Inverter indicates that the inverter is overheating. This could be because the inverter or the ambient temperature exceeds the operating range. Check if these temperatures are within the normal limits.
How to troubleshoot PvVoltFault on Solax Inverter?
A PvVoltFault on your Solax Inverter indicates a PV Voltage Fault. Check whether the PV voltage is overvoltage.
What does GridFreqFault mean on a Solax X3-PRO G2?
A GridFreqFault on your Solax Inverter means that the grid frequency is out of the acceptable range. The system will reconnect when the utility is back to normal.
What causes AcTerminalOTP on Solax X3-PRO G2 Inverter?
An AcTerminalOTP on your Solax Inverter indicates an AC terminal overtemperature fault. Check if the AC terminals are tightly connected and verify that the ambient temperature does not exceed the operating range.
What does HardLimitFault mean on a Solax X3-PRO G2 Inverter?
A HardLimitFault on your Solax Inverter indicates a hard limit fault (in Australian standard). Wait for a while to check if the inverter is back to normal.
What should I do if my Solax X3-PRO G2 displays RcDeviceFault?
If your Solax Inverter displays RcDeviceFault, it indicates a residual current device fault. Try restarting the inverter. If the problem continues, update the ARM software or reburn the program.
How do I fix a GridRelayFault on my Solax X3-PRO G2?
A GridRelayFault on your Solax Inverter indicates a relay fault. You should check the grid connection and restart the inverter.
What to do if Solax Inverter displays ResidualOCP?
If your Solax Inverter shows a ResidualOCP, this indicates an overcurrent protection fault. You should check the connections of the inverter and wait for a while to check if the inverter is back to normal.
