I use the eu2200i with the Magnum 3012 hybrid inverter running a Carrier Air V 15k air conditioner with a Micro-air EasyStart™ 364 Soft Starter that I added. Before adding the easy start it was hit or miss if the Magnum would fault since adding it hasn't been a problem even at 6,000' elevation.


Just curious, but did you try lowering the voltage cut-out??…Thanks,

No. When using the eu2200i I'll set the loadshare 15a, if using the eu2000i loadshare will be 13a.

I would only add that though the generator may struggle a bit while on Eco, the transition time for load switching is typically stated to be approx 16 milliseconds which equates to approx 1/2 of a single sine wave, so in the grand scheme of things the transition happens fairly fast…

Not fast enough to keep Yamaha2000iS from bogging down and sending the system into oscillation causing 400+A draw from batteries (and not doing the AC any good)…

How are you seeing a 400a draw, are you catching the locked rotor draw?

When I run the A/C off of batteries I can see 190a draw for a second as the microair slowly spools up.

Itinerant1 - watching the arc50 battery current draw is how I saw those numbers. I don’t fully understand why starting the AC when the generator was on and Magnum3012 in load support showed numbers higher than when I started the AC just on the 3012 without the generator involved. I suspect some of the issue is sampling, as well as syncing behavior of the 3012 as it attempts to titration current with the generator involved…but I do know the generator was bogging down during this as was the AC.

With that said, I tried it two or three times and got similar results: arc50 shows +30A or so charging batteries from generator; AC turned on and current swings momentarily to -400A 12v current or so, oscillates briefly then 3012 kicks generator out and settles down to -180A (had some lights and other things on) running AC fine; after little bit 3012 tries to bring generator back in (still running) and current jumps back up to -400A range again. After a few sequences watching this oscillatory behavior I chose to run AC off of batteries alone for an hour or so (it was HOT out) but didn’t want to subject my AC to any further experimentation.

I discussed all of this with Magnum tech support and their only suggestion was to lower VAC cutout voltage allowing more time for 3012 to establish load support instead of source replacement…again, I’m not inclined to continue experimenting to the detriment of my AC. I’m convinced my Yamaha2000iS just isn’t the generator for the job

When using either Honda generator I turn the "eco" mode off. MNRon have you tried turning the fan on only for a couple of minutes when first using the A/C for the generator & Magnum to sync up, then switch over to A/C. Before adding the microair I would do that and it did help to prevent the Magnum from faulting.

What A/C unit and size is it? What elevation?

“Not fast enough to keep Yamaha2000iS from bogging down and sending the system into oscillation causing 400+A draw from batteries (and not doing the AC any good)… “

Neither my former two GC’s nor my 200a/h LFP is capable of anything close to providing a 400a draw, yet either would run my 11kbtu air cond via inverter by themselves…Though I can’t now recall an exact figure, I’m certain that upon a Locked rotor condition, that the chemically sluggish GC’s voltage sagged considerably for a brief period of time…My sense is that it is in this way that lowering the cut-out voltage (strictly per mfg’s embedded limitation) would be an acceptable practice…

I should also add to my previous that my ProSine 2.0 inverter runs the 11kbtu air just fine, but my goal is to have the Honda 2200i to operate consistently while in the eco mode…

I have 630AHr Lifeline AGMs connected with 4/0 throughout, batteries have no problem supplying 400A. Even though it’s momentarily, I’m not happy driving those type currents in the Magnum 3012, nor the ~35+A that implies to the AC. Necessary to start, but oscillating around those numbers can do real damage.

As stated, I need a bigger generator, period.

My 3012 boost capability is great when plugged in to 30A as it allows me to run two ACs, misc light stuff and not pop the breaker when my wife turns on her hair dryer. I expect it will do the same when I get a beefier generator too.
