50 AMPS generator to power 2 ACs?

Hi, our new Globetrotter 27 arrived, will sell my 2021 GT 23 which I power with a Honda 3000is generator that gives me 30 Amps. How to boondock needing 50 AMPS, anyone knows of a generator (portable?) one can carry that provides so much juice? The only model I found is a Honda EB10000AG that weights 403 pounds, 9KW and is not inverter.

Just use the smaller generator you have or get 2 and parallel them and use the 30amp dog bone they have you. Will you need 2 a/cs, microwave, etc. all at the same time or?

Hi

For a full 50A you would need a 12KW generator. The 50A feed is at 240V. The 30A is at 120V. While it's not impossible to max out a full 50A feed, it's close to impossible with a trailer. You would have to plug a *lot* of stuff into everywhere on the trailer.

Simple answer is indeed to treat it like a 30A feed / be careful with loads and move on.

Just the two ACs

Returned today to Denver after a few days in Wyoming and Colorado State Parks, dry camping. 104 to 100 degrees daytime, needed all the AC I could get, with my genset 4.5KW and one AC, was able to bring it down to 72 during the day, nothing lower than that. On the 27 with more air to cool, more aluminum to the sun, etc I think I would need the 2 units running hard. No need to plug anything else at the time other than the water pump, the cell booster and maybe the TV with the Dish Traveller antena.

I'm always in the "more is more" camp, but asking for true 50 amp power from a generator of modest size is too much.
Remember, 50 amp power is TWO legs of 50 amp 125v.
Instead, work on managing the heat. Hopefully you've ordered the full awning package, throw some shade where you can. Stuff pillows into skylight and close it. Buy some reflective material and put it in the windows that aren't open.

Maybe?

I admit my almost complete ignorance on the subject. Maybe this will do it: https://www.grainger.com/product/HON...nerator-60NP45
? It shows: 25V AC 20A GFCI Duplex (2), 125/250V AC 30A Locking, 125V AC 30A Locking, 125/250V AC 50A Locking. Would that output provide for 2 ACs running with different thermostat settings, so they don’t need the extra juice to kick in at the same time? It has 9KW running and up to 10KW surge. Tried to understand the need for ‘two legs’ but that flies over my head. The reason to go a little against the standard of South in Winter and North is Summer (sometimes, not always) is because we do appreciate the disperse camping and the freedom of my German Shepherd to run free without annoying others, she is very happy exploring and chasing (never catching) other wildlife, swimming in lakes, etc.

That industrial generator specs out at 73db. This machine is designed to provide ample power at construction sites, not camp sites.

Hi

400 pounds is a *lot* to deal with getting in and out of a truck. As noted above, the noise level from the beast is not going to make you any friends.

Champion 4000 dual fuel is the way to go and you can add a smaller Champion 2800 watt and a coupler to get 50 amps. Our 2016 Classic can run both AC units due to soft start on bedroom AC. We are using the 4000 with 30 amps.

So I recently got rid of a 3000 watt inverter and I have 4 lithium ion batteries and 4 solar panels. Second owner so I know what was spent and it was a fortune ($30K) for little reward. I took the microwave off the inverter circuit it is a terrible energy hog. The lithium ions shut down to protect the batteries just above 10 volts. So you will be stranded if they shut down, I was. I had to jump them in the morning after running furnace all night it was very cold. and running the microwave first thing in the morning to defrost a bagel.

I really think it is a callosal waste of money for little return on investment. I converted the inverter circuit to shore power also.

If I ever want an inverter again I would go smaller and use the original circuit. I really can live without a microwave on demand. The solution offered to plug in the inverter circuit is a good one you could even fish some romex wire to create one underneath.

Really glad I got rid off the inverter, it was a victronix 3000 watt 16 amp and took up a lot of space in the interior, I was able to reclaim valuable space.

Hope this helps

Cheers.

Massive overkill, with easy start installed 2000 watts is enough to run each A/C. 4000 watts for both A/Cs plus a little more for charging batteries and watching tv 5000 should be plenty. This Honda would be plenty and much quieter. https://smile.amazon.com/Honda-EU700...s%2C172&sr=8-8

Boondocking implies certain life style adaptions as well as just parking in a field. Camp where there is power when it is hot and if the heat bothers you. ( I decided Cody with power was more fun that Teddy Rosevelt with no power after 1 day of 103 with no generator or AC). Actually we might have stuck out a couple more days being stubborn but it was awful hard on our older dog. So we just moved. I like campgrounds with hookups in very hot or very cold weather. I try to boondock where I can wear jeans and a tee shirt weather wise.

I just sold a Honda EU7000is with 67 hours on it and in perfect condition for $3800. I paid $4000 for it four years ago. I only used it for home back up power, and ran it through a manual transfer switch. It would run anything in the house except the main AC. It would, however, run a lot of stuff and two portable AC units. From the back yard to the street, about 100 feet, the noise was inaudible.

I took a look at that genset and looks very good. Now, the GT27 I got comes with 50AMP service, meaning also that the plug is different than the 30 AMP receptacle this generator has. A simple 50AMP female to 30AMP male adaptor would do the trick?

Thanks again!

This is the type of adapter I believe would be best.

If you want to run two A/Cs while boondocking do this: Install two MicroAir SoftStarts on your A/Cs. You may be able to run them with a 3000 watt genny. However, at higher altitude maybe not. I use a Yamaha 6300 tri-fuel genny that does a great job with 23 amps per leg or 46 amps total. It is larger than the 3000 and heavier (200#). No one can carry it off by themselves. I keep it under my ARE cap on a 3/4 ton Duramax. It really works well.

What can be wrong?

OK, I got the EU7000isN AN, not sure if it is the same you guys got but the start knob looks different, as in the attached pic and… I could not make it start. Battery connected but no juice, it has oil, filled the gas and pulled the cord some 30 times… nothing. Tomorrow will go to the dealer, I hope they can make it work.

50 AMPS generator to power 2 ACs?

Looks like there is a keyed main switch, and looks like in the off position

I love your choice! "More is more!"
Is there a key for the slot on the left? (sorry if I'm captain obvious)
