There is way more acceptance of the Champions and the HF units that are inverters now. People have seen the reliablity vs cost and they just make sense for a lot of us. Onan's are outstanding for built ins. Honda's remain top of the line with the price to match. I have been using a larger B&S inverter for the past three seasons with very good luck.

I see quite a few of the Champion inverter generators at the track and they seem to work well and most importantly they are pretty quiet.
One of my better investments into my racing program was when I built this tongue cabinet with a EU 7000 Honda on a slide.

So you want to buy the brand new roof top this is about year old?

A typical rooftop unit requires 15 amps running.

I replaced the 15,000 BTU Dometic upper unit on my Class C MH and it will trip the 15 amp breaker from my garage using a long extension cord and fed from a 15 amp circuit breaker fed receptacle...

Will run for 5-10 minutes and click !!!

Most std larger AC units can draw 3 times the running amps when the compressor starts.....Many cause issues starting and a hot start capacitor kit can help with that.

Never really can tell how well any given generator will work with an AC unit or a Compressor without trying it. Specs are one thing but actual how it works is another.

The bigger the generator the less likely problems will occur with motor starts....

Most AC units list what is called "locked rotor amps" and it is a big number compared to running amps....

A compressor has a pin unloader or some sort of check valve to relive the pressure in the compressor. If that device does not work, your compressor will just sit there trying to start until the breaker flips off or if it's a generator, it stalls the engine and trips the breaker on the generator...Amps go sky high....

Most newer RV AC T-Stats have a a time delay feature....Compressor will not start for a few minutes after turning on/off to eliminate the chance of line power issues from either shore power or a generator....

I run my toter and trailer off two small Yamaha inverters in parallel, but I’ve had a couple 95*+ tow days and the roof air would be nice going down the road.

I’ve considered a single larger unit, but I like that if we don’t need the air, I can just run one generator in Eco mode and use a tiny amount of fuel.

My 7500 Onan ran perfect in 2019 but this year it won’t turn over with a governor actuator fault. I’ve done some Googling but haven’t done much besides remove the front cover and realize I don’t know what I’m looking at.

The 7.5 Onan Inverter units are extremely popular but they can and will give you trouble.

The control unit is integral with the inverter unit....All in one.

I looked the price up yesterday on one....$2400 for the inverter/control and none available anywhere in the eastern region where I am.

They can and do / do some bizarre things....Trust me I've been there....

Like just start cranking on their own with no stopping until the starter burns up....Seen that one twice....

Onan at one time offered a rebuilt Inverter/Control....Not anymore and prices are higher than ever and availability is none existent right now....and no real answer for when....

No way, you can get a good one for same price and uses less than half the electricity meaning you can use smaller generator.

I understand your point but mine is I have brand new unit sitting on roof now.

.

That is with any electric motor you want a generator more than large enough to carry the load. Too small and it will burn up the motor.

What I have found is some generator manufacturers are "Optimistic" on their output ratings.

Which is another good thing about the Mini Splits they start slowly and ramp up as needed so they are quieter and use much less amps.

This is extremely true, last season I had one of those 4500/3500 Onan/Cummins inverter generators and it ran my 15K BTU AC just fine but I had to turn off the AC when I needed my compressor, other than that it worked great.
At Tulsa earlier this year the guy parked next to me had his gas Onan in his LQ take a dump. He bought one of these Onan/Cummins 4500/3500 generators at the track and it would not run his 13.5K BTU AC, it would run for about 5 minutes and trip the breaker and he and his wife had to suffer with no AC in the heat and humidity all weekend.

Champion generator is a bit noisier than a Honda, etc. Mine was well worth the money. The only thing I would do is get a quality spark plug for it. Mine came with a Chinese plug and didn't last long. NGK or Champion etc. equivalent to whatever is in it now.

Dang got to buy a 3 dollar spark plug that is insane .LOL

You can add this feature with a soft start. They aren't cheap, but they work well especially for older units that are starting harder. Even runs the fans for a minute before starting to help things even more.

The problem with the mini spits in a lot of applications is the logistics of it. Where to put a stand up unit and where to put the inside part, and how to run the lines in an already built coach....if it is a motorhome. Plus, most motorhomes are built for running 110v, and that really limits the size of mini split you can get.
I really like the idea of these though. They seem to operate far superior to the rooftop units.

Regarding Spark Plugs..

Do NOT use a NON-resistor spark plug in any inverter type unit

The RF noise a std. plug makes can cause problems. Been there and it was not fun.....cost a guy a lot of money....His mistake....

I use NGK's in all the machines I work on. And in my race engine....

Of course it did and of course it didn’t, you made a choice to buy Chinese garbage, the choice of the broke dyck crowd whose only concern is buy cheap!

That’s funny coming from the guy with a KIA parked in his pit area! Korean built but still overseas not supporting American workers. You can get off your buy American high horse now since clearly it only applies to people outside your family.

Newsflash p u s s y I didn’t buy it nor do I own it nor is it Chinese!

I think I bought my Champion 2000 around 2012 and have ran heck out of it. It is just as quiet as a Honda 2000 which is also made in China. Look at the box. Made in China. So if it is Honda made in China it is okay?

So you are trying to say Honda made in China Junk is better than Champion made in China? Right. What ever. It is more expensive.

Everyone here who has a Champion generator loves them and the only problem is a guy had to change a spark plug? A spark plug would never fail on a Honda. Right. What ever.

Giving your kid money to buy it still counts as you buying it.

Now run along and paint your Firebird to match the foreign shyt box like you plan to . Don’t forget the Kia logo.

P u s s y, my son bought it with his money, kid makes far more $ than you loser!

The mini splits are easy to do on a trailer but not on a motorhome. I have looked at my motorhome and just no good way to run them on it. And yes they are far superior to roof units.

Now on a trailer, mount the condenser above the tongue, run the plumbing under and through the frame then up inside the wall to the inside unit. Clean, simple and easy.
