Do you have a ring style amp meter? In addition to the other suggestions, I would measure amp loads on shore power for the unit and for the compressor when it kicks in. If all 3 units are the same BTU, check the starting and running amps on all 3. A unit with a marginal compressor may start fine on shore because of additional available amps, but have trouble starting on the generator with less capacity. It would be good to identify or eliminate the air conditioner as the cause of the problem.
