My apologies. I should have added that Watts = voltage times current. Therefore 2000 watts, as originally posted, divided by 120 volts equals 16.6 amps.

Now if we go with 2200 watts, amperage equals 18.3 amps.

Post #6 stated 17 amp continuous, or roughly 2000 watts. Take in account some looses for cords and such, and the converter running, altitude, etc., it will be tough to run the AC. Also if you have a 15,000 btu air conditioner, it will never start, even with hard start capacitor.

One other thing to keep in mind is many RV appliances require more amps to start the appliance than they do to run the appliance. A roof air conditioner can draw 16 amps to start, but may only use 13 amps once it is running.

thanks for the watt = voltage times current .
I never remember the formula and had I could have figured it out my self .

turbo, I also can't remember the formula (to just about anything) without associating it to something easier to remember. So, anytime I need to calculate volts, amps or watts, I think of a WAVE. As in Watts = Amps * Volts. The E is for excellent!

i have never heard of a Honeywell starting a Coleman a/c, even with a hard-start kit, on any RV forum. maybe it would a Dometic.
it'll be interesting to see if the OP can get it to work.

How much of the initial amp draw could be reduced if the Fan on the A/C is running prior to turning on the A/C unit?

Alright...thanks everyone. The capacitor is pretty cheap so I'm going to give that a try. I'll repost how it works after I get it in.

My honda eu2000 will start my roof AC on a nice cool day in Kentucky at
600 ft alt.
Out west at 6000 feet on a warm afternoon it won't.
I tried turning on the fan first so both motors wouldn't be trying to start
at the same instant but still no go.
I never tried a bigger capacitor.

Hondaman sounds like the EU2000 companion is needed to run your roof top with no problems. never mind I thought you had a Honda 2000.
can you link your generator to another?
