Recent experience w/ my eu2000:
I bought this gen after reading results of some on this forum and the camper mfg. owner telling me it would work on the ac in their units. About 3 wks ago picked up our new Outfitter Pop-Up Slide In capmer just North of Bolder, CO. It has an 11,000 Btu AC in it. The first night fired up the generator & turned on AC even though it was cool & we didn't need it. It seemed to work fine. Don't think we ran it very long though (this is important, stay tuned). Didn't start gen for another few days, cool weather. Went to S. CO. to rock crawling competition. Tried to use gen & ac. Wouldn't work at all. The gen kicked out & red light came on & stayed. It just wouldn't work..... We had put in a 60 jet in Bolder. Arrived home in Shreveport, LA. Put in stock 62 jet. It wouldn't start ac..... It would just barely power 350 watt drill. Took it to Honda. They said it would bog down w/ 3 amp load. Something wrong. They didn't find what was wrong, but after disassembly & reassembly it worked. Maybe trash in carb????? Took home, powered drill & fan together fine. Would start ac initially, but then later would kick out when compressor cycled on again. I think after the pressure completely bleeds off through the expansion valve then the unit starts easier (less load less amps), once the unit is running though, the pressure doesn't bleed off completely and the compressor has to buck that residual pressure upon re-start. More load, more amps. I have ordered a start up kit for the Dometic ac. Friend in ac business told me about these. I think it is esentially a capacitor which stores power and discharges upon start up of the compressor thus reducing amps the gen must supply upon start up. If that doesn't suffice I will rig up relays that will momentarily turn off fan and converter (battery charger), long enough (2-3 sec) for the start-up load/current draw to reduce to a level the gen can handle. The fan draws 3-4 amps, and the converter about the same I guess (3 amp output). Well, that is about 6-8 amps which is significant considering the continuous amp rating is 13+- amps. The continuous amp rating for the ac is 9. 5 amps & locked rotor is 50 amps. My understanding is that the locked rotor is the start-up current draw. The Dometic reccomended gen size is 2500 watt unit. At 120 volts that only works out to about 20 amps, so that tells me these generators can handle much higher loads momentarily than their rattings indicate.
Something else I'm toying with is seeing if an inverter could be hooked up to the eu2000. I know two eu2000 units can be hooked up together. Guess there is some kind of control connection to sync the inverters, maybe that could be done w/ a battery powered inverter as well. Hope the start up kit does the trick, really am curious about the experience of others that have used these units on a lot of rvs w/ no problem, even w/ 13000 Btu units. Maybe that was just a really good unit... ... ... . ??? Does anyone know if separate inverters can be synced some way???
