I am working on a prototype unit which is powered directly by solar and stores cold as ice for off-sun use.
This allows maximum power tracking of solar and run the compressor at peak output according to available solar energy...the cold is stored as ice and can be used at night to air condition the bedroom for sleeping...

There are DC drives available which can take direct solar DC power in the range of 450-600 VDC and turn it out into AC 3 Phase. Variable speed compressor would be best for this!
