OpalEnergy 12KW 3Phase is not giving output voltage after IGBT fault and repair

Featured Replies

Hi,

I received the above inverter, which is not running. I checked the IGBTs and found that some of them were broken. So, I replaced them and checked all the components around. The defected IGBTs were related to the Buck circuit.

After assembly and running on, the inverter is showing normal operation. However, I tried to measure the output voltage, and found out that no Voltage there!

I checked the configuration multiple times and did a factory reset, but the issue still persists.

I attached the screenshots below for reference.

If anyone could explain what's happening would be very helpful.

Thanks
