AirConditioning / Honda 2000/ Progressive EMS...issues

2 Hondas paralleled should definitely be capable of running your a/c. Personally I'd bypass the EMS when using the generators. It is really designed more to protect your electrical system from problems on the grid. The Hondas provide good clean power and even if you get a significant voltage drop during compressor startup, that won't ruin your compressor. What will is continuous running on low voltage but that shouldn't be happening with 2 paralleled gens.
