Your neighbors will love that loud monster. I powered my house 27 days from a generator. I was really the only one doing it. Some people had small generators and just used it a few hours each day for their refrigerators. I had the fuel and the power to run my whole house. I now have a generator that ‘s diesel and is super quiet. I did a test run on the weekend of 5 hours and nobody even knew.

You have to make sure all other breakers in the house totally off, start the inside air handler first, NOT the entire A/C system, the inside air handler should be on a separate breaker, once the air handler starts up, and is running for a few minutes, then start the outside condenseing unit, once your outside A/C unit is up and running, you can turn on other breakers you wish to run inside. It's a several step process but it should get you up and running on gas or propane.

*Update. I had to run this exact set-up 5 days after Hurricane Berryl hit H-Town. Worked flawlessly during the Heatwave for 5 consecutive days until our power was restored .

Thank you. that was a good watch.

If your generator will run your AC with natural gas, it should run with propane. The problem, I believe, is the single propane tank is not able to provide enough fuel. Get one of those Y adaptors to attach 2 propane tanks to your generator and it should work. Rather than 3/8ths standard propane hose, you may want to use 1/2" or 3/4" hose after the propane tanks are merged. I have a Champion with a Motor Snorkel installed as well, love it, more expensive, but I went 3/4" all the way.

A 4-ton A/C needs a 50A Generator like 12k or 13k to be able to start and run the a/c unit(s).... I bought this Champion inverter Generator 8750w/ 7000w running on gasoline. On propane will dropped to 6000w, on Natural Gas maybe 5400w only which Hopefully will Run my 2ton A/C unit (s). I think I need a Soft start too

I haven't read all the comments but consider increasing the capacitor size inside your softstart unit to further reduce the LRA a bit more. I see you have a micro-air and these guys are super helpful. I have a 3.5 ton AC but had to go with their larger sofstart (for the 5 ton) to get my LRA to under 34 AMPS (Originally is 104). This solved my issue without bitting the bullet on a larger inverter generator and installing a 50am inlet for it . Hope this helps.

I had to change sitting on soft start from normal to defualt ramp and mine worked on 4ton a/c(same generator)

Yes, you need a larger generator. I have a Firman Tri-Fuel running on Natural Gas and the same soft starter. It is connected to my panel and my 4-ton A/C runs fine along with other items in the house.

Even if the peak start is above your surge on the generator, it should still start. The power factor, how quick that surge is, and the fact that the amperage shoots up because of the voltage drop. I believe what happens is that on some starts, the pressure in the compressor is high causing it to take a bit more to start. This causes a severe drop in momentary voltage which in turn runs the amperage up significantly and why you saw 70 something amps on that first pull. The soft start sees it as an overcurrent and cuts the power or the soft start takes longer to start. With it being to close to not starting it sometimes, you might want to ditch it starting the AC. I have a 5 ton and 8500/11500 generator. Easy start would get start amps to 35ish. As soon as it was on generator power, that was 50-60. Sometimes it would fail to start, sometimes it would get it. I didn’t see that as a viable option so I returned the easy start. Im sticking to cooling just half of my house on a newer 3 ton. Generator never has an issue starting it so I feel comfortable leaving on over night with the many cycles it does.

Just jump up a bit and use that one as a backup! One in hand is better than two in a bush! Enjoyed the learning!!!

You discovered one of the downsides of inverter generators; they don't surge well. Looking at other comments, it sounds like you were able to richen up the engine to get a little more power out of it. Also, a few hundred watts of standby loads in the house, here or there, could make the difference. It would be cool if the easy start could be tuned to optimize the starting current or trip thresholds even lower. Cheers!

Jonathan, I am a dealer for Motor Snorkel. Great video, however I think your AC unit is too big for the Champion model you have, regardless of what fuel you use. Even with a Microair Easy Start unit, the running watts I believe are too much. It is not advisable for any portable generator to run at max wattage load for any significant length of time. For example if your 4 ton AC takes 6kw to run (not start) then you need ideally an 8-10kw continuous generator for extra capacity. I will be doing a video soon in the next week or so on a Tri-Fuel Conversion. The important note a lot of people miss is how to adjust the load block above the demand regulator. LEANER is better/cooler on propane/NG. It's the opposite with gasoline where leaner means HOTTER combustion temperatures which is BAD. Cheers and keep up the content!

I did a test run on my Champion Power Equipment 100520 8750-Watt DH Series Open Frame Inverter today. Number 1 problem is RFI. If you have AM Radios, then forget this generator. The RFI is no where near as low as my 1990 Honda EX4500 which does not interfere with my AM radios. This Champion 100520 will not be replacing my EX4500. It will remain a good higher wattage back up.

Great content! I recently purchased the harbor freight version of this inverter generator (same output but gasoline only). Had a coupon that brought it down to $900. We have a 3 ton AC upstairs and 2 ton downstairs. Having the house wired next week with an interlock switch and I'm going to install the micro air soft start on the 2-ton unit. We spend most of our time downstairs anyways except all of the bedrooms are upstairs. Not a problem at all to use an air mattress or sleep on the couch to stay cool during the summer if we have an outage. I'm thinking the 2 ton unit will start easy. For heat, both units are gas and draw very little power. Gas dryer, gas range, gas hot water also helps reduce our power load.

When you cut main power and restored with auxiliary power your EasyStart went into a time delay mode and will not function properly until it resets. If you can switch from gasoline to propane on the fly I would start A/C with generator on gasoline then switch to propane while the A/C is running. When your A/C is off the pressure will equalize and your lock rotor amps (LRA) on start up will be the same regardless if it’s been off for a half hour or two weeks it will be the same. Hope this helps 🇺🇸

Just subscribed, and watched your detailed video on this generator. So did you upgrade to a larger size champion generator, or are you still with the 8750w??? Btw how is that generator holding up this year???

I'm a bit surprised since I own a tri-fuel Champion model 100416 with specs similar to yours. Like you I have a Micro-Aire easy start installed on both my 4ton and 2.5ton central air units and either will run on natural gas along with the fridge, microwave, and lights. I manage the loads, i.e., I don't run everything simultangeously without reducing the loads. I would call Champion and/or Micro-Aire for some feedback and question whether your "Snokel Tri-Fuel" is providing enough gas pressure, although I would think running on gasoline should provide enough energy. Have you tried to "relearn" your Micro-Aire? Starting amps seem high to me with the easy start.

At what pressure did you set the propane regulator? My propane test on a converted HF generator showed that 1 psi "flooded" the engine, and it would not start. 1/2 psi worked fine, and the generator immediately surged to carry a twelve-amp load. Will unsuccessful tests like this damage the A/C compressor?

You need to use a shorter Generator Cable no longer then 12feet The shorter the BETTER ! your cable looks like 35 feet which will Drop a lot of Amperage ! Try a much Shorter Power Cable First Before Buying a Bigger Gene .

Hello i was curious what kind of app is that were you can monitor your power? Thanks

Interesting wonder if the xp1300eh generator would be able to power the 4 ton ac 🤔 seems like it should on paper but barely.

Are you running your house off the generator at the same time your trying to run your air. Turn off breakers until your air starts up.
