Once you have identified the problem, you can begin troubleshooting it. Here are some steps to follow: Check the input voltage. The input voltage to the inverter should be within the specified range. If the input voltage is too low or too high, the inverter may not function properly. Check the output voltage and frequency.
Input overvoltage of the inverter is usually caused by a problem with the substation that increases the voltage at the inverter power supply. Or it could also be due to a problem with the power supply of the capacitor. Once you have verified that the input voltage is normal, refer to the second cause below.
Reason 3: The DC input voltage is too low. When the string output voltage is lower than the minimum input voltage of the inverter, there is no display on the inverter screen. To make sure, you can use a multimeter to measure the output voltage of the photovoltaic string to see whether the voltage reaches the minimum input voltage of the inverter.
In this article we look at the 3 most common faults on inverters and how to fix them: 1. Overvoltage and Undervoltage Overvoltage This is caused by a high intermediate circuit DC voltage. This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter’s DC voltage.
Then measure the input voltage or check the DC bus parameter at fault (you can check this parameter in the monitor parameter set of the inverter). Input overvoltage of the inverter is usually caused by a problem with the substation that increases the voltage at the inverter power supply.
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.
