I have a question about sizing a generator after adding the Coleman Polar Cub Mach 8 AC addition to my Bigfoot camper. Please forgive me if the answer seems obvious. I lost my beloved wife to covid 47 days ago and I can't even remember which end of the tooth brush to use. I don't have clarity right now and with the fog from being sick, not much seems clear.
So I read a lot of postings here and there about running the Mach 8 on a Honda eu2000i. Which I currently have as an extra. Last summer I upgraded our Bigfoot with two 100aH lithium batteries. I also put in a Progressive Dynamics 4655LIV lithium converter charger. I just found out it draws 950 watts. The specs on the Coleman Mach 8 say 1550 watts. When I plug into AC power the batteries start charging from the converter automatically. How are people running the AC on a Honda eu2000i rated at 1600 running watts when other loads are most likely present? Turning off breakers?

I had started to look for a couple year old Honda eu2200i that did not have the CO minder. I have a generator box on a trailer that is vented with doors and it would shut down from CO readings. The eu2200i is rated for 1800 watts. However add the 950 from the PD4655LIV and I get 2500 watts. I really should be looking for a generator with at least 2500 running watts correct? Honda makes a eu2800i generator. 67 pounds and moderate on the noise. I don't want to make another mistake.

Why a Honda? I have a westinghouse 4500watt 3700 running watt that I am absolutely sick of. 20 hours on it. It is to much generator for what I need. It kills batteries, won't pull start and run with a dead battery, and two days ago I spent 30 minutes trying to get it started after running it just the day before. I can't stand that 107 pound POS. Every honda powered item I have here starts and runs without more than three pulls. Sometimes only one. I see dozens of cheap generators on the market. I bought one and I hate it. So anything with a Honda motor is a possibility. But back to my question on output. I need something bigger than the eu2200i correct? I am not into turning breakers off to run my AC on a small generator.
I am wondering how people are running the mach 8 on a 2K output.

Oh I forgot to mention I am getting a soft start from micro air no matter what generator I end up with.
I appreciate any input. There is a lot of knowledge here.
Thank you.
Al


Almost new to truck camping. Truck is a 2001 Dodge 3500 Dual rear wheel with a few performance mods. Camper is a 2005 Bigfoot 2500 9.6 with Lithiums. The trailer carries gear, one quad, two kayaks, two bicycles, and a 3700kw generator.

I would go with the honda eu3000i or the lighter version of the eu3000i. I would not use the open frame industrial honda to camp.

Al, sorry for your loss. I have a Mach 8 on my TC and run it with my Honda 2000i. I would definitely install the MicroAir and then see if you can run the AC while charging your lithium batteries.

We have 0 issues starting the same A/C with the 2200 Honda; also if’s you first go to “ Fan High” then to “Cool High” it will make starting the compressor easier!…

2200i and Mach 8 here. So far, so good. Have not tried it at altitude yet, so MicroAir might yet be needed..
I have no experience with lithium, but 950 sounds like a lot. Convertors generally provide a variable load as battery state of charge and and dc loads dictate. Since my ability to carry gasoline is limited, I shut off the convertor and switch the fridge to propane. These are my only two AC loads.

Sorry for your loss.
About the generator, a Mach 8 will run no problem off a Honda 2200.
The draw you're seeing for the charger/converter sounds like max load, IE, batteries run down. It charges/maintains at a much lower rate when batteries aren't low. Just keep the big loads off while running the AC (microwave, other devices with heating elements) and it will run a small AC like that.

Well all encouraging news. It occurred to me that I could get a second companion eu2000 and run it only when needed. I have room on my little trailer for it. I did however kind of want to upgrade to the eu2200i since running the 2k gen I have will be at it's max running watts. I am also trying to be conscious of the noise produced when in a campground. I don't want to be THAT guy...[emoticon] I need to try what I have. Right now everything is winterized. And it is snowing. Summer ended way to quickly.

I appreciate all you folks responding. I wish I could go camping right now. So darn peaceful out there.

Why wouldn't you try the AC with the 2000 first? Bet it works!

When AC draws huge amps for compressor starting, I measured 13.5k BTU to run on 6.2 amp and 15k on 8.6 amp.
Meaning once the AC is running, you don't have to worry about power spike till it would restart. Trick is to set thermostat very low and turn AC off manually, so it will not restart without your knowledge.
What size of inverter/charger do you have?
With proper size it is very easy- plug inverter into generator and start the AC on inverter power, once AC runs, start the generator and inverter should automatically switch to generator power, when at this point AC will draw low amperage.
Advanced inverter/charger will dose the available current between AC and charger.
