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.
Severe over-voltage: The inverter has completely shut off as the voltage is past the threshold for extended periods of time Moderate over-voltage: The voltage is on the edge of the threshold and the inverter is turned off for a very short period only to turn back on; thus the spiky solar profile. What can you do to resolve this?
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.
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.
