Technical FAQs 4

What happens if inverter voltage is too high?

Exceeding the specified maximum input voltage for an inverter can lead to various issues. These include overheating, potential damage to internal components, and the risk of a malfunction. To mitigate these risks, manufacturers often incorporate overvoltage protection mechanisms into their inverters. How do I choose an inverter voltage?

What causes an inverter to overvoltage?

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.

Can a DC inverter cause a voltage spike?

Some inverters allow adjustment of DC bus voltage targets or thresholds. Incorrect configuration can result in higher than normal bus voltage. The pre-charge circuit limits inrush current and gradually charges the DC bus capacitors. If malfunctioning, it can cause voltage spikes.

Can a DC inverter overvoltage be measured?

One thing to keep in mind with the overvoltage fault is that it only happens instantaneously at a certain time. Therefore you can only monitor the DC bus voltage stored on the inverter at the time of failure, it is not possible to measure the overvoltage at this time.
