Is that the grid or generator you are connecting to?

44 Hz is very low and the multi probably wont connect.

Also, when I dewire the ac in cable at the inverter the voltage is present within the inverter!

Please check your wiring and measure the voltage with a multi-meter.

The screenshot shows that there is 120V and 44,8Hz at the input.
Did you maybe connected the output to the input by accident?
