portable generator/air conditioner issues

I have a 2018 Surveyor that is driving me batty. I power up my Honda2200 generator and when I turn on the air conditioner the generator powers down and a cautionary light goes on. New to all of this so any help would be appreciated.
Thanks,

Research Softstart RV or Easy start Micro air

Have you tried a soft start system, like the Microair Easystart?

As alluded to above, sounds like your generator doesn't have the wattage to get the A/C started. My previous trailer didn't have a built-in generator, and I tethered 2 Honda EU2000s together when I needed to use my A/C. So, buying a second Honda generator would be an option (albeit a costly one).

The EasyStart suggestion is a good starting place, though. It will allow you to get the compressor started on the A/C with less watts, and then your single generator should be able to run the unit once it's gotten going.

You’ll need a soft start for the AC or run two Honda 2200’s in parallel to generate the amount of electricity needed to run the AC along with any other needs.

Or do both. Get a soft start and a second Honda 2200. You’ll have the best of both worlds.

Is it a 13.5k or 15k A/C? MicroAir Easy Start should help with the 13.5k but I'm not sure what the start up load is for the 15k.

And if your batteries aren't 100% turn off the breaker to you converter so it's not trying to pull extra amps.

portable generator/ air conditioning

I'm using a Honda EB2800 generator so i'm pretty confident that the power source is sufficient. The trailer is 2018, could the AC unit have crapped out already? Or could it be a maintenance issue. If so, could someone walk me through whatever steps would be proactive.
Thanks,

The ac unit will use all the output of the generator.

Can we assume the water heater, electric fridge, converter and other large electric power users are off.

Does the A/C work when plugged into shore power?

2800w is still on the upper fringe of starting an A/C (especially a 15k unit) unless you have made mods to the A/C and are positive ALL other circuits (especially water heater and CONverter) are off at the breaker.

And yes, it could have crapped out. There are tons of posts about A/C units failing because of various reasons. Other than cleaning the condenser coils periodically, checking for mud dauber nests and cleaning the interior filter(s), there is no A/C maintenance.

I have a 13.5 BTU AC with a soft start and still need two A i-Power 2350/1850 generators to run it off grid.

Once the compressor is running it will usually run on one generator while the second basically idles. You see the second generator kick in when the compressor comes on. My gensets show the load they are each handling on a digital display. That's how I know this.

I have a 15k with MicroAire Soft Start and have no issues with a single Honda 2200.

Have not run into an issue with the converter adding too much load either. Definitely won't run the electric water heater, coffee pot or microwave at the same time as the AC.

In your original post you said you were using a Honda 2200 generator. Which is it - - 2200 or 2800?

Which AC do you have - - 13.5K or 15K? It makes a big difference.
Honda EU2200i = 2200W startup & 1800W continuous
Honda EB2800 = 2800W startup & 2500W continuous

13.5K AC requires 2750W to start & 1250W to run after start
15K AC requires 3500W to start & 1500W to run after start

If you are using that 2200W genny, it will not start either AC without a soft start.
Even the 2800W genny won't start a 15K AC. It would start a 13.5K AC - barely. If you have any other load going it may not - - which could be what is happening.

Either way, just because you think your genny is big enough does not make it so. My guess is that your AC is fine, you just need a bigger genny or a soft start.

BTW, that EB2800 is an open frame, industrial generator. Your neighbors won't be happy about you firing that thing up in a campground.

It is not your AC. Your generator is not up to the task.

OK, which Honda do you have? You posted two completely different models.
Also do you have a 13.5k or 15k a/c?

I also have a 15k with a MircoAire, and have no issues with my 15 year old Honda eu2000.

I run my 13.5k A/C with a honda 2200 just fine, but I added a micro air easy start. Search google or youtube for videos. As others stated, your A/C if probably fine, your generator isn't powerful enough to start the air conditioner.

Your original post said: Honda2200

So everyone is as confused as me .....

Our Westinghouse 2500/2200 runs our 15K Air unit on our Surveyor just fine.

But, I don't let anything else with a high load run simultaneously.

I also start the fan on auto and let that run for a bit. Then turn on the actual Air Conditioner. Runs just fine.

Good Luck.

Same for me. But, when using the AC with Honda 2k generators they are a lot quieter when running both units paralleled together.

What elevation are you at? Internal combustion engines lose power with altitude. I don't remember the exact numbers, but at 8000 feet MSL your 2200 watt generator provides about 1500 watts. With our 2019 Surveyor, our 2500 watt Westinghouse generator powers the air conditioner just fine most places. In the mountains it wasn't enough, so we added a Soft Start to the air conditioner. My guess is that a Soft Start may be enough for your 2200 watt generator to work near sea level (or in the Midwest), but not in the Rocky Mountains. You will probably need more generator there.
