The builder in the video said his system ran 2400 watts at 60Hz and around 900 watts at 30Hz. I wonder what the practical relationship is between frequency and compressor output. It would be interesting to see a plot of COP vs frequency.

$153 is a good price for the compressor though I expect the shipping to be another $60. I already have a few VFD's.
