What Causes Inverter Overload. The most common reason for a power overload is when the inverter is used to its hilt or instead reaches its peak power output. This is caused by a high intermediate circuit DC voltage.
Disconnect nonessential load equipment from the UPS to eliminate the overload. Both inverter input and output circuit breakers protect the inverter its wiring from damage as a result of current overload or faulty wiring. The power reaches the peak.
If the three-phase voltage at the motor side is not balanced the three-phase voltage at the inverter output side should be checked again.
This particular inverter is designed to plug into wall AC to keep the batteries charged and pass through wall power when it is available. Causes of inverter output circuit breaker trip. This is caused by a high intermediate circuit DC voltage. Lastly lets test that the cabling is not the cause of the overload.
