The AC voltage overrange is the most common failure of the solar inverter connected with the PV grid system. This is because the grid voltage is not constant and it will change with the changing of the load and current. At the same time, the output voltage of the inverter will be affected by the grid voltage.
The voltage is pushed up to 252V + 4V = 256V for over 10 minutes and the inverter trips. 3. The maximum voltage rise between your solar inverter and the grid is above the 2% maximum in the Australian Standard, because the resistance in the cable (including any connections) is too high.
If the AC wire of the solar inverter is connected in a wrong way, the AC voltage overrange failure may be caused. If the phase wire and zero wire are connected wrongly, then the inverter A phase will show that the line voltage is 380V and the B, C will show that the phase voltage is 220V.
3. The maximum voltage rise between your solar inverter and the grid is above the 2% maximum in the Australian Standard, because the resistance in the cable (including any connections) is too high. If this is the case then the installer should have advised you that your AC cabling to the grid needed upgrading before solar could be installed.
