I suggest you post this in one of the Electric Engineering forums to get the most effective respones. Also, post all of the electrical information for the unit: Motor sizes, volts, amps, single or three phase, etc. I suspect the problem you will have is the current required during the startup of the motors.

You need about 13/14 kw/hr or about 6 hp. This takes into consideration the compressor, supply fan motor and the condenser fan motor.
