We have been on about 6 trips in our new TC so far and for the first time this week got into a little heat that was uncomfortable for the Wife. We were just looking for an hour or so to cool down a bit during the heat of the day. I specifically got the 9k AC unit to run on our Yamaha 2k and knew it might be tough.It ran the unit fine in my driveway (of course) for about 30 minutes, sea level, 80 degrees ice cold, no problem, batteries charging and a couple of lights on. We tried to use it twice this week, 2 different spots, both about the same altitude WA Cascades about 2500’. Edit-ECO WAS OFF.1st attempt-92 degrees, part shade, fail. Even dx’d the battery switch feeding everything, poor little genny. 2nd attempt- 88 degrees full sun, worked. Ran it for about an hour, much happier Wife, batteries charging, couple of lights, no trips.Thinking maybe a Honda 2.2k might get it done better? It is the same size and will fit in my custom compartment just fine also. The Yami also struggles to run my fridge and chest freezer at home during power outages. I have a buddy that said He’d give me $650 for it, bought it new for $875 several years ago. Might be time to bite the bullet. Anyone have any experience with the new Honda 2.2k and a 9k AC in similar situations?

make sure you have the refrigerator running on propane, make sure the hot water heater is running on propane, not electric and as a last ditch effort you can throw the breaker for the battery charger. I would expect that gen to run the AC. I have a different 2K generator and never had a problem, but all my camping is at Sea Level at the beach :)EDIT: after reading more posts, I feel I do need to point out that my red 2000 runs my 8800 btu AC on my arctic Fox great, even on eco mode. and I have mine wired so thermostat turns on both AC AND fan the same time. I can also leave the battery charger running at the same time but by the time of day I would be running my AC I have already gone through a full solar day of charging batteries so not much load on charger.

No experience with the new 2.2 Honda but I have the same AC on my Northstar Igloo and the Honda 2.0 just handles it as long as it isn't in Eco mode. I'd love to have the 2.2 to have just a bit of extra oomph but the 2.0 will get the job done, even in 100 plus degree heat (think the Badlands at 103 indicated). Just a data point on the old Honda so the new one should have no issues. Surprised the Yamaha can't handle the same load with the same rating.

Spin up the fan before switching it to the low ac setting.

I know this topic is contentious but after a bunch of research I'll picked up a Ryobi 2300 (RYI2300BTA) generator this summer. Aside from the Honda with it's Hondaness and the Yamaha with it's Yamahaness, the Ryobi seems like the best inverter gen out there. It runs my 13.5 btu Dometic with eco off (and with the charger/converter on). I've been very happy with it and it has some nice features that others do not have.

Was bit disapointed in the Yami, Wife was pissed! We live in W. Wa and 90 starts hitting Us ((Her)) pretty good, especially after activities. I’m pretty sure I had everything dx’d by hitting the battery dx switch. My fridge shut off and all the lights when I turned it to off. I definately had eco mode off. I reset the genny several times slowly going in to AC low, couldn’t do it.

Converter still works with disconnect off, just isn't charging battery.

Exactly, that's what I was thinking originally, wasn't 100%. Figured if it didn't have the batteries to charge it wouldn't have much draw.

I think at this point i'm going to get my ducks in a row better for next time, figure out which breaker is for the converter and such, keep the Yami for now and go from there.

Thanks for all of the replies and ideas.

ECO was off, 100% sure, I knew that going in.

Leave the Eco off for AC use, pretty sure it says this in the generators manual as well. This will give full rated power and prevent a low voltage situation on start up damaging the AC compressor. Votlage will dip down into the 80s on eco starts which can be very damaging to motor windings.

I use 2 Yamaha 2K in parallel for my AtWood 13.5 AC

My fridge was on gas only. When I hit the battery dx switch the fridge went dark along with everything else in the camper, still wouldn't run. I guess i could look into hitting the breaker for the converter, but that kinda sucks, be nice to give the batteries a bump and not sure the converter is working when the battery disconnect switch is off anyway, or is it? Maybe it was just a combo of altitude and heat? Had about 6 in me, maybe I missed something, new to powering the AC with a genni. I'll try again when we heat up, but not with altitude.

I run that AC with my Yamaha 2,000 although it definitely is not on ECO and it does scream, but I also do not turn off my power converter while doing it. Don't care what the specs say, you will find variation between AC units and also genny output between units.

Wait, you used the battery disconnect switch? That won't remove the load of the converter or guarantee anything about the fridge. Once you fire up the generator the converter powers the 12V for the fridge and the fridge will also see 120V. You need to be sure the select LP and turn off the circuit breaker for the converter. If I misunderstood, disregard but I am surprised it wouldn't do it.

The fridge alone takes ~300w. Our Honda 2k runs the Polar Cub 9k on ECO with the converter ON.

Put a MicroAir on your AC for $300.00 and your Yamaha should have no problem running your AC.
