Unquestionably YES!
If the compressor has cycled out for more than about 3 minutes, it will be starting against zero pressure differential.
Turn the compressor off (move thermostat to warmer) and then almost immediately turn it cold again, the compressor is trying to
start against full pressure. BAD! Overload! Non-spinning motor.
A properly designed A/C unit will trip a thermal overload and then reset after a few minutes. Hopefully, working normally afterwards.
And yes, the genset will be overloaded while the compressor motor is locked and before the A/C's thermal overload trips.
