My Yamaha 2400iSHC can handle it, but you need to be running the fan first before you turn it to 'cool' and allow the compressor to start. When the compressor cycles off and then back on, there is a brief 'pause' in the fan. I'm guessing that if I installed a hard-start capacitor (next spring!) that will completely take care of it.

I too considered going with the dual 2kw Hondas or Yamahas, but you're easily looking at $2,100 with the parallel cables. I got my 2400 from Amazon for $1,389, and it does the job.

I was just looking at that very same EF2400iSHC Yamaha generator. The The Honda folks suggest I purchase the eu2000i, and the eu2000i companion and run them parallel. I would prefer using, and buying just one.

Thanks Bob. I really wish I had found electronics and autoshop more interesting when I was younger!!

The main breaker will trip.  Just disconnect (or unplug) whatever is causing the excess current draw.  When we lived in the Midwest, we sometimes wanted to use 2 1500 watt electric heaters.  Our 30 amp service was not adequate for both plus the incidentals that we wanted to use.  My solution was to install a separate 20 amp plug on the exterior of the trailers and install a dedicated outlet just for that input.  A separate 12 gauge extension cord was then plugged into the campgrounds electrical box, and in effect, we ended up with 50 amp service.  That outlet was reserved for the second portable electric heater, and used only when we needed the added heat.  Just a thought.

The pods are so small, the need for this additional capacity is probably not needed.

Ok, quick question. If we are using more than the 30 amp hookup will cover, does it damage the rpod or just not let you use something? I am completely ignorant toanything electric so please be gentle in your laughter!!

The Yamaha EF2400iSHC is marketed specifically for "HIGH CURRENT SURGE OUTPUT - Using the latest inverter technology the EF2400iSHC provides quicker reaction time to load and reduced current drop at start-up. This enables efficient starting of most 13,500 btu RV air conditioners."

Apart from that, you'll likely have to go to a 3000 watt unit to be confident that a generator will start your A/C.

Yes, it was turned off.  In ECO mode, the generator would cut out when the A/C kicked in.

I also happened to have my sound meter handy Smile

All measures of the Hyundai 2000si were taken from the same spot, 15 feet from the front of the generator (exhaust pointed the other way), 15 feet from the r-pod's A/C (i.e. I was between the generator and r-pod), with no obstructions in front of, behind or around the generator or r-pod, 20 second average:

- 50 db - at idle, no load (r-pod not plugged in), ECO mode on
- 54 db - under load, A/C not on, pod plugged in (battery full not charging, microwave & DVD plugged in but not turned on, fridge and water heater on propane), ECO mode off
- 59 db - under load, A/C running, pod plugged in (battery full not charging, microwave & DVD plugged in but not turned on, fridge and water heater on propane), ECO mode off
- 58 db - under load, A/C running, pod plugged in (battery full not charging, microwave & DVD plugged in but not turned on, fridge and water heater on propane), ECO mode on (turned on after A/C had started)

The last one was just a curiosity as it won't work in a practical application (well... it may work if I were to install a start capacitor on the A/C).  Note: the running A/C will have artificially inflated the sound level; unfortunately, I was at a dry site and couldn't run comparisons on mains electricity.


For comparison, the Champion 73552i measured (again, from 15 feet)
- 54 db - at idle, no load (r-pod not plugged in), ECO mode on
- 56 db - at idle, no load (r-pod not plugged in), ECO mode off
- 59 db - 500 watt shop light plugged in, ECO mode off
- 67 db - 500 watt shop light plugged in, A/C running, pod plugged in (battery full not charging, microwave & DVD plugged in but not turned on, fridge and water heater off), ECO mode off

I've heard of the same problem with other mechanical-governor gensets - with an initial load being the only solution like you found.  Interesting that the inverter-based Hyundai could handle the surge.  Assuming it has a low-idle (eco) mode, did you have that turned off?

My Yamaha EF2000iSHC generator drops off line when this happens.


 

I measured the A/C's power usage a while ago using my blueplanet energy meter.  It peaked at 10.5 amps / 1210 watts.

But, like you, I tried unsuccessfully to run the A/C with a 2000 watt generator; in my case, a brand new Champion 73552i.  The genny simply couldn't handle the ramp-up of power.  I was able to get it to work by also plugging in a 500 watt shop light (to keep the genny's idle high), but that's not much of a long-term solution.  I was unhappy with the Champion for other reasons as well (much louder than I thought reasonable under load, quite smelly in operation) and returned it to Costco two days after I purchased it.

Instead, I bought a Hyundai 2000si generator (2200 watts peak, 2000 watts continuous), and am quite happy with it: it runs the A/C without problem, its quiet in operation, and there's very little exhaust smell.  This is the second Hyundai generator I've owned.  I had a 1000si which I used with our last trailer, a pop-up, for several trouble-free years.
