FAQS 4
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.
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.
Why does my inverter show a red light?
Generally, reasons when the inverter shows a red light include: When it is detected that the input voltage is too low, the inverter will automatically switch to the under-voltage protection state. When the input voltage is detected to be too high, the inverter will automatically switch to the overvoltage protection state.
What happens if you overload an inverter?
Overloading the inverter regularly can negatively impact its efficiency and overall performance. It may lead to voltage fluctuations, increased power consumption, and shorter lifespan. Overloading an inverter can strain connected electrical devices, potentially causing them to malfunction or even suffer permanent damage.
