Hey,  I have gone down this rabbit hole. Kingtec Solar air conditioners have   
   been developed to do what your talking about.   
      
   It's more than just a compressor.  Here is a description of one of our   
   products.   
      
    Solar window unit description:  16000 btu -- E.E.R. 18.6   
      
   Kingtec Solar air conditioners come completely ready with built-in connectors   
   for solar panels, power converter and batteries. All the necessary cables are   
   provided. The A/C has a 45 amp mppt solar charge controller inside the unit.   
   There is an external    
   enclosure for the AC to DC power converter option.   All of the necessary DC   
   overcurrent protection fuses and breakers are installed in the air   
   conditioner. Quick fuses for solar surge protection  and grounding are also   
   installed in the unit.  The air    
   conditioners come with two year warranty on parts and one year on the   
   compressor   
      
      
   So - How much did you say you were willing to pay?
