Sold the Honda 2000i and got a 2200i , now I can run the AC

On the 2200i, my experience is it is a significant improvement over the 2000i.

1) the engine is now 125cc vs 98cc on the 2000i
2) rated output is up by 200W
3) I have the service manual for the 2200i. typical output voltage curve shows a no load output voltage of 126VRMS and a full load rated output voltage of 120V RMS.

My experience with the 2000 with the micro air at 4500ft and 95F is it would easily start my Coleman MachIII AC but would trip the micro air overload after running 10 minutes or so, then restart the AC after 5 minutes and repeat.

With the 2200i at the same altitude and temp, not only would the honda run the AC easily for hours on end, but also run the fridge on AC (an additional 300W load)

And it has a run dry mode on the fuel switch.

Add to this my brother with a micro air tried his honda 2200i with his AC unit at 7000ft. Once everything else was turned off, the honda was running the AC unit pretty much continously. He did need to turn off eco mode to keep it from overloading, and on occasion on first turning on the AC would run for 5 minutes or so, turn off the AC then restart after 5 minutes then continue to run the AC for a few hours as needed.

the micro air has it's own overload protection for the AC unit monitoring the AC motor rpm and when it detects to much of an rpm drop along with a few other measurments turns off the AC for 5 minutes then restarts.

The nice feature is that if one has the AC on and accidentally turns on something like the microwave, the micro air drops out the AC unit before the generator overloads, lets the microwave or other load run then after 5 minutes will try to restart the AC.

No one's ever had a problem running running 120vac rated USA stuff down here with Mexican rated 127vac power. The real test of a prime mover is a high head re-start.

Shut the A/C down when it's good and warmed up, then try and re-start it a minute later. If it bogs the generator, it has to be avoided by a) no run b) continuous running of the load.

Honda inverter generators normally output about 128 volts with no load, and are pulled down to about 120 at their rated continuous load.

Both of my EU2000i gensets maximum unloaded output voltage was 126 vac.

Broke it in last night then tried the AC in the trailer at 95 degrees. During break in I threw some good loads at it including a 1250 watt hair dryer and a box heater 1500 Watts at the same time (2750 watts).

So what is the break in procedure, I see nothing in the manual? Typically it is a good idea to run new equipment gently for a period of time.

This is what I did....
1. Dino oil, run it for 15 min no load with magnetic dipstick, then vary from eco to non eco a few times. Drain oil, clean dipstick, refill oil.

2. Run for 5 min, put hairdryer or vaiable loads between 250-1000 watts for 10 seconds followed by no load for 5 minutes, both on regular and Eco mode a few times. Drain oil, clean dipstick, refill oil.

3. Run for 5 min, hit it with max load for 10 seconds then no load for 5 min. Repeat using Eco mode (to vary rpms and throttle) do this a few times. Idle for 5-10 min then do what you want for load....run no load for 5 min, drain Dino oil and clean dipstick (wont be much on it anymore).

The whole thing took me about 1.5 hours.

4. Fill with Mobil 1 and enjoy.

So Honda now makes an EU 2200? Probley phase out the 2000.

Not "probably" - the EU2000i was discontinued with the introduction of the EU2200i earlier this year and remaining unsold EU2000i gensets have been discounted.

Honda inverter generators normally output about 128 volts with no load, and are pulled down to about 120 at their rated continuous load.

So Honda now makes an EU 2200? Probley phase out the 2000. Glad it is working for you. Good info. Thanks

Did notice however in the trailer killawatt was reading 128 volts at no load.....seemed a bit high.

5% over 120 vac is 126 vac so your reading is slightly high. Being a consumer product your P3's calibration won't be exact either so I personally wouldn't give this any thought at all. As one who has previously owned 2 different EU2000i gensets the new EU2200i is definitely what I'd purchase if I were in the market again. :B
