How much generator?

Have a 15,500 AC unit on my 22FB Jay flight TT. Also have a 2000W Yamaha gen. Is the gen. large,(watt wise) enough to run the AC for 5 hours ? Assume it does not run out of gas.

Thanks again, Planning on a 5-6,000 mile road trip next week going thru some high humidly.

It might be able to run it if you have a soft start installed on the air conditioner. I run my 13,500 btu unit with a Champion 2500 duel fuel inverter, with a soft start installed. It runs the air conditioner, but not much more. Even with a soft start running a 15,000 btu unit, and a 2000 watt gen may be asking too much.

I had to flip off all other breakers to get my 15K air conditioner to start on my Eu2000i. After I installed the soft start, I could selectively leave on some loads. Microwave and hot water heater would both trip it if the air conditioner was running. If the batteries were topped off I could turn the converter back on. If not, it would overload the generator as soon as it went to bulk charge.

I run 2 Honda 3000 tied together to run my 15,000. On a hot night they'll run about 7. Sometimes when I wake up one generator is out of fuel and the other is at 1/4 tank. Sometimes one is at 1/4 the other little more. No breakers off, no soft start.

Don't forget about both the nominal rating (rather than peak) and altitude.

Your 2000W generator isn't really a 2000W generator. It's actually a 1600W generator that can do peaks up to 2000W for a few seconds or minutes (depending on the version of generator). For starting the A/C, it's good to consider peak. For sizing a generator to the other loads and constant draw of the A/C, you need to think about the nominal rating of 1600W --> 13.33 amps available (P=VI).

The next is altitude. I'm not sure where you're at, but normally aspirated engines will lose about 3% of power per 1,000' over nominal, and nominal is usually 500'. So, if you're at 2,500', then you will lose 6% and your 2000W generator is down to a 1500W generator.

Where I'm at, camping at 10,500, I'm losing around 30% of my engine's power!

A 15.5K BTU A/C is probably going to draw between 15-20 amps on startup. If you're at altitude, you probably can do this without tripping the generator. If you're higher than that, then it becomes a roll of the dice. Probably need more power or a soft-start or both.

THANKS to all who replied . I have never needed to use my generation for anything but carry it as a back up of minor things or to run a compressor in case of a flat tire . So what is a soft -start? Also what about the inverter in the TT I do not know the size of it. Thanks again I do not know if I need to buy anther generator ?

A soft start for the AC is a device that ramps up the starting of the AC, instead of the sudden surge of high amperage that the compressor draws without one. This able you to use a smaller generator/ inverter to run the AC. I personally think overall it’s better for the AC for its longevity. Google Micro air soft start. That’s what I have. I’m using a small 39 lb Champion duel fuel inverter to power my 13,500 btu AC

I just got a Champion 5500 dual fuel inverter generator with electric start, it runs at 61db with 5500 peak and 4000 running. I got it at bass pro, so far I really like it. It’s a little heavy at 118lbs dry but it fits it the f150 with the bed cover on.
