Your first step is to hook up the generator to the trailer and run some other AC items like the microwave or just plug in something to one of the regular AC outlets. If all is well there then the air conditioner compressor might be drawing too many amps during startup (known as locked rotor amps). Also make sure nothing else is drawing power from the generator except the trailer's converter.

What is the rating of the air conditioner? 13,500 btu, 15,000 btu or something else. Does the air work when hooked up to shore power?

Your generator has a continuous rating of 3500 Watts and a surge rating of 4000 so it should handle the air conditioner, but not much else. I have the champion 3400 Watt inverter generator with a continuous rating of 3100 Watts and it runs our 13,500 btu air no problem, just don't ask it to run the microwave at the same time .

If the air is in good working order, it might just have a high startup amperage. You can try installing a hard start capacitor (the least expensive option) or try the Easy Start from Micro Air (a bit expensive).


Hard start capacitor: example only, your air conditioner might require a different model
