When you're doing the numbers you must keep this in mind.

The advertised rating in watts for generators are peak watts that it can handle. An electric motor will surge to much a higher draw than rated for a few seconds and that's what the rating is taking into account on generators. They can surge to the higer number for a few seconds.

For example: The Honda EU2000 is rated at 2000 watts or 16 amps. It will only handle 1600 watts for continuous operation so that's the number you want to use. That's about 13 amps. An air conditioner can draw 20 amps continually and surge to 22 or 23 when the compressor starts. Other electric motors to consider; pumps, fans, furnace fans, etc
