6 Frequently Asked Questions about “Inverter voltage high power-off protection”

What is inverter over-voltage protection?

Everyone often encounters the problem of inverter over-voltage protection when dealing with inverter faults. The over-voltage of the inverter means that the inverter voltage exceeds the rated voltage. The over-voltage protection of the inverter is caused by the over-voltage of the inverter.

Can a power supply cause an inverter to overvoltage?

Most of the inverters now have an input voltage of up to 460V, so the overvoltage caused by the power supply is extremely rare. The protection measures for the overvoltage of the inverter vary according to the cause of the overvoltage of the inverter.

What causes inverter overvoltage?

There are two main reasons for the inverter overvoltage: the inverter power supply overvoltage and the inverter regenerative overvoltage. The overvoltage of the power supply means that the DC bus voltage exceeds the rated value because the power supply voltage is too high.
