I want to know if you have an inverter Air Conditioner, and the things of been an inverter Air Conditioner is that it take AC electricity and converts to DC, so the motor on the compressor can be adjusted to the desire BTU. Why you don’t have a bank of batteries (solar rechargeable), and connects directly to the air conditioner omitting the AC electricity, and perhaps been more efficient in the process because you’re omitting the conversion of electricity.
