Is my generator big enough?
I have have a Coleman 2500 watt generator and I am wondering if it will pull my rooftop AC on my 19ft travel trailer? My rooftop AC is a Duo-Therm Model: 57915-541. It does not say how many watts it...

You probably actually have about 2200 or 2300 watts. 2500 is probably surge.
Generators will be rated in watts and your manual probably says that if you have a 13,500 btu ac it requires a 3500 watt gen. Many will run on less.
They are saying that if you check your system voltage as the ac works you can see if the voltage drops too low.
2300 watts divided by 120 volts equals 19 amps.
If you can borrow a clamp on amp gauge it would be good to check amp draw. You want to see starting amps and amps as it cycles on and off with compressor head pressure.
Remember that your converter and anything else on 120 v will add to the ac load. Put the frig, water heater on propane
You dont want to run maxed out because it's hard on both pieces of equipment.
I just checked my rig and the ac was pulling 5 to 6 amps but the ambient is only 60. I have seen it pull more but cant remember how much.
Beg borrow or borrow a clamp on amp meter.
