AC with generator

Hello all. Does anyone run their AC (we have two but would just need one on geni) on a generator. I have one with a 30 amp plug we used in the old camper. I installed a hard start on that unit. We have 50 amp now but figure I could use an adapter and keep the amp pull down when needed. Iíd like to run just one zone when needed at Walmartís or someplace on the way to our campsite. Being in texas, AC is a necessity. Thanks

This question is asked almost weekly.

As long as your generator supplies the rated watts for a 30a plug, you can use one A/C unit at a time.

Being your R/V is a 50a service, you will need to be cautious to not use more total current (other things besides the A/C) than 30a.

Well, if there's no shore power, the only way to run the a/c is with a generator.
You'll need a minimum of a 3000w INVERTER generator.
There are literally hundreds of threads here, asking the same question. A quick search will give you weeks of reading.

a 30 amp trailer could consume up to 3600 watts (30 amps @120vac). if you can get a 3600 watt generator with a 30 amp plug in it a 30 amp trailer would not know if it was plugged into shore power or a generator. whatever you could run on shore power could be run on the generator. you may not get both a/c's running with that generator but you should be able to run one along with converter and some other small devices.

if you can get a generator in the 5000 watt or better range you can probably run both a/c's simultaneously. we have an onan 5500 and we are able to run both a/c's. the key here is to get a generator that can supply power to both of the 50 amp power leads.

Yes I have run my ac with my generator,.
I have a big load generator that runs it fine.
I do have a plug in volts meter that I monitor my volts with.
Make sure I'm over 105 volts with ac on

Thanks. I have checked the units I have and they appear to already have hard-starts on them, yippee! I should be good, just have to figure out the zone 1 and 2 setup to make sure itís doing the right one.

you don't have to figure out anything. get a 30 amp male to 50 amp female adapter. plug it into the 30 amp receptacle on the generator and then plug your 50 amp cord into the female side of the adapter. this will put power on both legs of your 50 amp system. so you can run any electrical device. the limitation will be that you will still only have 30 amps in total available to use. this 30 amps is the capacity of the generator. if you exceed it you will overload the generator and its circuit breaker will trip.

That's what generators are for
We run our 15k a/c and the rest of the RV with our two Honda EU2000is. Sometimes 24 hours a day with a nurse tank. No biggy.

Installed a Micro-Air Easy Start on our AC unit, a Honda 2200 runs our 13.5 MBH AC with no problems now.

Thatís great! Itís always good to know you have a geni that runs the ac, especially down here in Texas! The new trailer we just picked up is much friendlier with our geni. The old unit just didnít like the power source I guess, even though it is an inverter. Happy camping!

Karlrmac - congrats on running AC off the generator. We did similar this past weekend. Anyone know if the AC is damaged if the generators run out of fuel in the middle of the night?

If it's an inverter generator, then no. They will have no power fluctuations.
If it's a contractor style, then it will have power fluctuations as it runs out of fuel. May or may not hurt any devices or appliances currently running.

You do know that campgrounds don't allow running generators overnight?

That's what I was wondering. Were you guys camping in the federal/state forests?

At some point during every day you suddenly realize nothing else productive is going to happen the rest of that day. For me, it usually occurs around 9 am.

Not EVERY campground has the same rules.

As mentioned, campgrounds on the properties of NASCAR and music festivals we've visited often allow gennys running 24/7 and could care less if they are open frame type or inverter.

Also as mentioned, State and National campgrounds are completely different.

You have to know the rules for YOUR particular spot!

My daughter's farm in Carolina does...


Horses and cows didn't seem to mind, but the chickens paid us back at zero dark 30 the next day...

Unhappy Not Happy with Predator

Wish I could do that..Just returned from a west coast trip and never needed a/c until we got to Michigan, Ohio and finally Penn.the second week of july. Such a cool start to summer..Battery was recharged easily when not moving with 2 to 4 hrs a day when dry camping...all appliances worked fine except too many at once and never a hair dryer with our 4000/3200 Harbor freighter Predator...Happy we saved money and all was well till we needed one A/C the last week of our 2 month trip.....Cannot run ECO and one a/c just to cool the trailer What could be wrong??Do you think I need the easy start or what...
