Fault Reasons:Inverter will show "Grid Voltage Fault" when detected the AC voltage is out of range of selected country's limitation.
1. Check if the impedance of the output cable is too high to lead to the grid voltage increased, change a thicker cable to check if the problem is solved or not;
2. If you are using an aluminum cable, please change to copper cable lower down the voltage;
3. If this fault caused by the grid voltage in the installation place is over the limitation, please contact sunways after-sales team at service@sunways-tech.com or +86 400 9922 958 for help.
