Generator Size For Camper A/C

[ZapMan]

Does anyone know what size generator is needed to run a rooftop A/C in a camper. I would like to stick to a Honda 1000, because of the weight. I want to use it for ice fishing also, and would like to keep it light.

a 1000 will definetly not run your AC....I don't even think a 2000 would do it, you would probably need to go to the 3000. the 1000 or 2000 would run everything else you need it to.. If you're going with the 1000, I'd recommend going to the 2000 instead. Not much of a cost difference, and you'll get lots more capacity for things like toasters, coffee makers..etc. Someone else may be able to help you further on your AC question, but my opinion is that you'll need the 3000

you need to figure out the start up pull on the ac. that is what requires most energy, everything else is nominal. the tag on the a c should give you the watts consumed at start up and when running, using ohms law figure what the amp draw would be then go from there.

Power in Electrical Circuits

Electrical Power, (P) in a circuit is the amount of energy that is absorbed or produced within the circuit. A source of energy such as a voltage will produce or deliver power while the connected load absorbs it. The quantity symbol for power is P and is the product of voltage multiplied by the current with the unit of measurement being the Watt (W) with prefixes used to denote milliwatts (mW = 10-3W) or kilowatts (kW = 103W). By using Ohm's law and substituting for V, I and R the formula for electrical power can be found as:

To find Power (P)

[P = V x I] P (watts) = V (volts) x I (amps)

I have the Yamaha 2400, it has a peak of 2400 watts and it does run the AC in my 5th wheel. It puts out a bit more juice than the Honda 2000 and is still pretty portable at 70#

Same generator here, with same results. Good luck, Junky.....

What does the 2400 run in $$, compared to the Honda 1000 and 2000?

I paid about $1100 for my 2400 yes it is a bit more than a honda 2000, but it does put out more juice and is more portable than anyones 3000.

Thanks for your input, and ideas.
