Yeah I only has the 2000 watts and the 1800 running so you might be better off with a bit more juice.

I wish I could open that attachment bigger I can't read the figures they are posting for it. Did HVAC for 20 some years, would like to see the specks better....

I did some HVAC as a helper in high school but I spent more time in attics wrapping insulation than I did learning about the details. But from what I read, starting amps is about 1.64 times running amps so starting amps on the compressor alone would be about 15.9 or about 1800 watts at 115 v. That sounds a little low however but would be nice.

Well your pretty close with that # but when you add up your FLA at start up and running at 90 degrees you are only looking at 13.1 amps FLA. That's not much but maybe on a ginny. Where this 6.5 amps for a fan motor came from I don't know your fan at FLA is only 3.4 amps and that is also on start up....Thanks for the bigger picture...

At initial start up of the air conditioner, the amps would be close to LRA (50 amps) and then rapidly decrease to the FLA ( 13 amps) that is the reason a generator needs to be sized properly to all load in an RV that a person wants to operate at same time.....

So they starting amps on the fan motor is about the same starting and running? Thanks

To Tall no matter what you do I would think that a must is a hard start kit on the compressor, as far as the fan motor go's if you are running a genny it would be best still to delay the Fan Motor with that time delay the one Turbs showed will work fine on the 12 volt side control wires. These little units there really not much difference between high speed and low speed CFM wise. I always think it's better to run your A/C on high speed, but that is just my opinion. If you are changing your stat to digital your only going to be able to pick high or low, without adding a switch as some members have done using a hunter or honeywell.

Thanks, yes I noticed very little difference between high and low fan. I already purchased the 12 v Dayton before this discussion confirmed it would work. I connected it yesterday and it's working great. I received the 2400/2100 gen today late and got it going. After a little brief break in, I plugged on the TT with nothing on but a light and the convertor. I haven't installed the hard start yet but the ac cranked right up just as it did on shore power. I will add the hard start tomorrow.

What I'm wondering is when temps get up in the 90s, if it will still perform. It was only 55 to 60 deg today. Seems like I saw a chart some where on the web that estimated the various evap and condenser loads at various temps.
