Bob, I have picked up a similar unit with a GMCC compressor. It's marked 180V at 180Hz. Also looking to run it on VFD if possible. Which VFD did you try and why do you think it ended badly?

Also- I found this website that breaks down the GMCC compressor model numbers - it show the power usage and a COP.

I've been reading every thread I can on here about heat pumps. It seems that these inverter units are a tough nut to crack for the home hacker.
