Thanks all for the replies. Here’s some more info…
The ac doesn’t work on shore power either. Right after I finished this install we did try to run the Ac for the first time on both inverter and shore power. During these tests the compressor would turn on and off like it wasn’t able to sustain itself. And now it will not work on either shore power or inverter. The fan on the ac runs but compressor does not. I feel like having the soft start should have been sufficient in running the ac off inverter.
The AC is a 13500btu roof air conditioner by dometic (dometic brisk air 2). The inverter has a surge rating of 6000w and 3000w constant so I feel with the easy start it should be ok?
I have the following parts:
