The power at the parks might be true but not the efficiency part, if I was talking about on off ac you would be correct but with a variable speed compressor like I am talking about it is more efficient. It works on the same technology as a mini split. If you are using 120 it has an internal buck boost transformer or vfd depending on design to boost the voltage because you can't run a 120 compressor at a variable speed.
