Help from an electrician please

I need help determining why my two Honda EU20001's (one is a companion) won't lite up my electrical system. I do have a Progressive Industries EMS-HW50 hard wired. Starting from the back, I have two EU200i's connected with the Honda cable to each other. Then going from 30 amp female connected to an 30 amp to 50 AMP adapter to the 50 AMP connector on the Fiver. I thought I should be able to get my 28 AMP 120 Volt. Instead with the EMS-HW50 on, I get nothing, if I turn the EMS off, I get momentary 120 volts and within 30 seconds a loud chattering that appears to be coming from the EMS-HW50C.
I thought I had this in the bag, but now I know I need some electrician advice. Do I need to run a bypass to my EMS? Is generator power different than shore power as related to the EMS or converter?
Sorry for the long post. Please, I need advice. Thanks.

If the genny is okay I would check the 30 to 50 amp adapter. It should be no different than hooking up to 30 amp at campground.

Have you checked the gen output using a good VOM? Is the voltage from the gens correct? It should be around 120VAC up to 130VAC and definitely not over 132VAC.

Are the connectors wired correctly.......nothing crossed? Google 50amp RV wiring to see what each blade should read and you should be able to use your VOM and check the gen output to be sure each blade of the connector is supplying either 120 or ground or neutral.
My best guess is something's amiss between your gens and the end of your cordset / adapters.

The Honda EU2000i is rated for 2000 Watts surge capacity and 1600 Watts continuous duty. Continuous duty is 26.3 amps for the EU2000i. I would go back and start checking the 50 amp connector to the EMS.

If the Honda's are truly putting out 120 Vac you either have a bad EMS-50HWC or a bad connection. The by-pass switch does have to be on bypass because using the ginnys you do not have a bonded ground and the EMS will not allow that but in bypass it should work just fine. I do it all the time and so do a lot of other people.

I would look at several things.. First the voltage out from the generators, But measure at several points

The outlet (You should be seeing 120vac) the RV end of the cord (Should be the same) if you ahve an on board auto transfer switch (I do not think you do) input and output terminals, I'm not sure just how/where the EMS splices in but there too, and finally the master breakers in your breaker panel (120 volt to ground zero breaker to breaker when on Generator 240 when on 50 amp shore power.

Also, if you have a meter that can measure FREQUENCY (Kill-a-watt does this) check that too.

Home is where I park it!
