Will this work on my 10hp air compressor setup going from single phase to 3 phase setup? Or is there a larger one that works better for this applicati

It should work, this converter runs at 50 hertz, it ramps up from 0 to 50 hertz slowly. I am using on a 30” band saw that is very hard starting and it works flawless. You will have to Remove the factory switch on your compressor and wire vfd in its place, I am not sure of the wires for the pressure switch. But yes this vfd will convert single to 3 phase.

Does this unit have auto-start when input is energized?

It can if you set that option. Defaults to no.

I continue to get tE error no matter what i do. Heard a pop inside the unit im guessing a cap blew. Anyone have similar problems?

I can't answer your question specifically, but I have had 4 of these units fail. IMHO, these units are sub standard. None of the ones which failed were being "pushed", all of them were rated at least 50% above the load they were controlling. I suspect you are looking at a failure oh one of the triacs, not a cap. Since switching to another brand of VFD, I have had no failures and better performance.

Will this power a 1950s 10hp 3 phase american tool works pacemaker lathe on single phase or 220? i do not have 3 phase service.

yes that is what this is desigfned to do
