Free Quote6 Frequently Asked Questions about “Inverter output voltage exceeds the standard”
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 does overvoltage mean in an inverter?
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. There are two main reasons for the inverter overvoltage: the inverter power supply overvoltage and the inverter regenerative overvoltage.
What happens if the inverter voltage exceeds 255 V?
This means that when the average voltage for a 10 min period exceeds 255 V, the inverters will be automatically trip and the corresponding status on the eShow (LCD module) will display “Fault 014”. The customer may increase the voltage threshold up to 258 V (the upper limit required by the standard).
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.
Why should the inverter power supply be stopped?
When the grid encounters abnormal situation, the inverter power supply shall be stopped to avoid more serious damage on the grid. Based on the national standard, the protection range of the under-voltage and over-voltage at the AC output side is the 85%-110% of the rated voltage.
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.
