Hi, Steve; Unless I missed it the OP didn't say what size air conditioner that he has nor did you mention any air conditioner size in your statement. For the record my Yamaha 2400 generator with a constant 2000 watts output ran my air conditioner, my converter, my refrigerator, and a small television all at the same time and at high altitude. My air conditioner is the small 11,000 BTU model. Others who have the same generator, or the newer improved model, can run their larger air conditioners, but have to shut everything else off.

Yes, Bob, at 11,000 btu I suppose the smaller generator would work. I am surprised they put that small of a unit in a 25 footer. Mine were all at least 13,500, and now this trailer has a 15,000 in front with a "small" 13,500 in the rear.

Even with all this capacity, if we stop for the evening in the summer in West Texas, it's at least 9PM before it cools down in there. I know it's a lot different on the West Coast.

I think you mean 2600 watts, 3000 would be better. My 1985 air conditioner I would guess needs 2800 watts because when the compressor cycles my eu3000i get loaded down pretty hard.

No, actually I meant 3600, and that's what I would get one for myself. 30amps X 120volts=3600 watts, and if you buy a 3600 watt generator, that rating is peak, and it will not sustain that level of power output for very long.

The OP has a late model 30ft trailer, so I'm sure he has the big air conditioner.
If you have a 15,000btu air conditioner, run the converter, and the wife turns on her hair dryer, well, there you go.

Consider the other purpose of having solar, specifically keeping a charge on your batteries when in storage. Just like others have pointed out that camping under a canopy of trees regularly cuts down on the efficiency and utility of your panels, so too when you store under cover.

I bought my RT van without solar because I knew I would be storing under cover and even though there might be times I could benefit from having solar charge the batteries while parked elsewhere, its a marginal advantage. When I camp, I am usually having hookups. Interestingly, I use my ONAN propane generator to keep a charge on the batteries when in storage for prolonged periods. I could, but would not remove the batteries as I do with my trailer, so its nice to have the generator to maintain the batteries, and yes, it also meets the ONAN warranty requirements for monthly running.

So It seems to me that a generator has much more utility than panels. I have a similar 2400is for my trailer, and like it. I also like having it for times when my home power goes out, and while I have a 7.8 kW system on my roof of my house, I do not have battery backup yet, so if the grid goes down, I am SOL, but I still have my trusty Yamaha to keep the deep freeze and fridge going. I am waiting for the TESLA home backup system to mature and will likely add that on to my home system, and possibly my van. In the interim, I am considering dropping the ONAN on my van (too noisy to use), and adding the engine generator. Its 3500 watts and burns diesel. Adding more batteries in the space to where the ONAN sits is also in the plan. Depending on your TV, you might be able to do the same... Engine generators are much quieter than stand alone units and probably can be used when sites prohibit regular generator use...

I thought you were talking about what was needed to run just the air. Now to give the camper 30amps 2 Honda eu2000is would match.
