Angry Generac IQ2000's

Thought long and hard about this purchase vs the Honda 2000's. Using them for backup power I knew they wouldn't be used that often. The Honda's would run about $2200, these were $1450, both prices include the parallel cable. First use I found they would not continually run my 15k AC. Keep in mind the AC cycles (even before set temp is reached) and draws a transient current over 40 amps. The AC cycling would cause one of the gen's to speed up momentarily then when it slowed the "breaker" would kick. I imagine the Honda's probably have a smoother transition. I brought them into a Service Center close by and the tech checked them out thoroughly and no problems were found. It was his opinion that the gen's couldn't handle the above referenced transient start current, I agreed. Anyway, the solution was purchasing an electronic addition in the form of a microprocessor controlled board from MicroAir to reduce the start current to around 18 amps. The gen's work fine now, easily run the AC plus additional loads.
The Generac's seem to be well built, we'll see in a couple of years. I figured for the limited use and reduced cost they would be fine. I am happy with the results all things considered.

I think a hard start kit would have done the same for you thats what I have on my rig. I run yamaha's 2000 in parallel and have never had a problem. They do cost a little more then the Generacs but a little less then the Honda

I had the same problem with mine when I tried to use them. Have you got any information on the part from MicroAir, I would be interested in trying it.

I bought the 364 enclosed board, it is an easier install (vs just the board) and is weather proof. They also have a video showing installation and results measured with a current meter. It was interesting in their video when they showed using a hard start capacitor, like some do, did not reduce the start current. Nice to buy a product the actually performs as advertised. IMO the MicroAir would be a good addition even if the generator(s) someone has run the AC.

If you are running the AC you should not use eco mode.

My 11 year old Honda EU2000is run my 15k a/c on eco mode all the time without any easy/hard start. And that's with the converter and usually the TV on. And I can use an extended run fuel tank without having to make any mods. Guess there is a reason all generators are compared to Honda

Would an expensive easy start be beneficial? Sure!!! But not necessary. If I was worried about it, or had under powered generators, I believe I would go the cheaper hard start capacitor route.

If only one of the paralleled generators revved up, I would think the parallel connection was not functioning correctly.

Hard start capacitors don't reduce the transient start current. You are right about the Honda's, they are great gen's. If I was going to be using them for anything other than backup I would have bought the Honda gen's.

Thanks for the link. Do you know if I am running 2 AC units (not at the same time) if I need to put 1 on each unit??

Also I thing my main problem with mine is I had to turn my surge protector off when hooked to the generator because it will not power up my unit when on.

Yes, each A/C needs a soft start.

This has to do with some kind of floating neutral/grounding thing:
