It depends on what you want to power up. If you want to have the full 50 amps, you will need a generator that's rated for 12,000 running watts.

Well I don't know about that.

I have a 7.5Kw in my coach and I can power everything up at the same time with the generator alone.

Yes the Honda's are a nice unit but the 2000W ones won't get you too far, and daisy chaining 3 of them to get 6000 would
not be worth it to me.

However getting a 6000w generator is going to be somewhat heavy and noisy compared to the Honda's.

Generac makes some nice units but cost a little more - Then again do you want it to last - don't skimp on this if you want reliability.

How many things would you be running at the same time will determine what size you need.
If you have 2 AC unit and could get by with just one running you could get by with less BUT if you don't want to just get by I would
buy a bigger unit - but like I said it will be heavy and do you have room for it?

Most people find that a 3000 watt generator works well for them, if all they have to run is a single roof AC unit and some other light duty odds and ends. While not light, a 3000 watt'r is still light enough for the average person to carry around. Honda makes a great generator, as does Yamaha.

Well, a 50A shore power connection has up to 12,000 watts available. Whether you have enough stuff in your RV to actually consume that much would depend on the RV and how it is equipped.  Many coaches certainly can do so, or even exceed that, but many can get along nicely an about 7500 watts.

We have two ac units. But wouldonly run one if down south. We really just want it to run regular systems. Sayif the power goes out pull the plug and replug into the generator.

Well in that case you could start with a 2000W or 3000W Honda as they are light and small and easy to pack in your 5W.
Then if you found it would only handle 1 AC unit and not much else then you could buy another and daisy chain them.
But I think a 3000W would run 1 AC unit with no problems and probably a few other thinks like your fridge too.
If your only planning on only using it when the power goes out that should be more then enough since the power doesn't
go out too often in most places.
If you ever go boondocking well then that might change things - but if that's not in your plans then I would probably
start with one Honda 2000w or a 3000w and see how it goes.

Do you have an inverter on-board your 5W?

Hello folks,

I must be missing something. 50A x 120V = 6000W, so a 6-7KW generator should be enough, no?

Anyway, if I were the OP, I would start with one like this:
https://www.amazon.com/Champion-Power-Equipment-100263-Generator/dp/B01FAWMMEY

It's dual fuel (ie it does run  on propane, useful to avoid carrying gas around just for the generator specially if your RV is diesel, and also for not having to worry about stale fuel gumming up the carburator) and should provide enough oomph for a single AC. For dual ACs turned on simultaneously, it can be paralleled with another one like it and then should give you 50A easily.

Also, Champions have good reputation, 3 year warranties and cost less than half per Watt than the Hondas (which are not dual fuel).

And no, I'm not a Champion salesman nor connected to them in any capacity ;-)

Cheers,

Fifty Amp service is actually two legs of 50A each at 120V for a total, of 12, 000 Watts. They provide two sets of 120V circuits.

Ah! So that's what I was missing! :-)

I knew it had 2  legs of 120V, but I thought they were 25A each so 50A *total*, not 50A each.

Thanks for the clarification.

Cheers,

As has been noted what size genny depends on what you plan to power.

Battery charger only.. 1,000 watts (A TRUE 1000 the EU-1000i may or may not do the job depending on your converter but a GENRAC 1000 will)

Microwave or water heater or an air conditioner all take around 1500 watts running and a whole lot more on teh A/C starting,, 3,000 watts for one A/C is the minimum.

Full power...  Well my 50 amp Class A came with an ONAN 5500 watt and yes that does the job.. that is also almost exactly 1/2 of what 50 amp park power can provide.

I have left over power as another forum member can attest.

IF you are partial to Honda's I'd go with a pair of either EU-2000i or EU-3000i  The latter will give you nearly the full 5500 watts I have.  But the former should do the job if you are a bit conservative (Run water heater on GAS or do as I did and change out the 1500 watt element for a 1500/4 (375) watt element,, that's a 1500 watts at 240 volts element running on 120 volts if you need to know how to find one. (Halve the voltage divide power by 4))

We have a Honda 2000i.  Use it frequently even though we have a hardwired 5500 Onan.  It's quieter, less costly to run and unless we need AC, it adequately runs most everything in our RV, just not everything at the same time.  If you want to run the AC, consider the Honda 3000.
