Technical FAQs 4

What causes a DC inverter to overvoltage?

This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter’s DC voltage. There are other causes of DC overvoltage, however. POSSIBLE FIXES: Turn the overvoltage controller is on. Check supply voltage for constant or transient high voltage. Increase deceleration time.

What are the most common faults on inverters?

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.

What causes overvoltage & undervoltage?

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. There are other causes of DC overvoltage, however. POSSIBLE FIXES: Turn the overvoltage controller is on.

How do I know if my inverter has a low voltage?

The audible alarm will sound as a warning that the DC Input Voltage is getting close to its limits on the Low and High End. Battery Voltage must be above 11V Battery Voltage must be below 15V With a multimeter test for DC Voltage at the Battery terminals of the Inverter to verify you are within the operating voltage range.
