Progressive EMS to the rescue! Watch out for WEN generator
I posted this info in another thread but thought it necessary to start a new one.
This is my generator setup. Just bought them last week. Cheap units, have the ability to parallel, can use elsewhere, quiet as the expensive brands, I can lift into the bed by myself and should run both A/C's.
$1223.00 for both including the parallel kit...otd.[/QUOTE]
CAUTION!!!!!!!
I recently purchased these generators and THANKS TO my Progressive industries EMS I discovered that the Chinese factory worker who wired my generators and the Parallel kit wired the L5-30 recepticals with reverse polarity. As soon as I attempted to power my camper through this particular plug the EMS shut off the power and produced an error code.
Plugs wired backwards were these:
I contacted the local distributor I purchased from and informed them of the problem. They looked into it at their end and called me back thanking me for discovering this. They pulled several generators out of their stock and found the same problem with them.
They offered to correct the blunder ASAP at their center but I opted to open the panel and correct it myself. 1/2 hour later I had correctly wired generators........ Yay China!

Nice set-up! Wouldn't work for me, I don't think, because the canister for my roll up bed cover would be in the way.

I have the same problem. I use a Yamaha 2400 placed by the tailgate.

I dunno - looks like DJNCJ's bed cover fits just fine over the gensets...
I just put my Honda i3000 in front of the hitch and go, but I have no bed cover.

DJNCJ,
Did your EMS not detect an open neutral when first connecting to your trailer? My EMS-HW50C would not pass the power from my Champion 2000i inverter because of an open neutral. I found later all portable inverter generators have floating neutral. The below link has a good explanation about it. I made the plug that is shown in the article so I could use the generator for my MH.

Good question!
Prior to trying them out on the trailer I checked the recepticals with a millimeter. To my surprise I found these generators came from the factory "neutral-bonded" so no need for a bonding plug.
The EMS approved of their power once I had properly wired 30 amp recepticals.

As DJNCJ noted his brand of portable generator had a bonded ground/neutral whereas others may not.
Most on-board generators that were installed by RV manufactures such as mine made by Onan come with a bonded ground/neutral.
If using a portable generator and do NOT have any EMS installed in your RV, then I would strongly suggest that you check this out and correct it.

I am using a tri-fold cover that stays above the bed rails.

floating ground
Why couldn't you go inside the generator an cross over the outlet plug an both outlets would still be useable an not have to make a bonding plug

I have since done that. Made up the plug to check that the EMS would pass thru the power from the portable generator.

Talking about an ems, would it be better to get a hard wired or an external plug in?

On board hardwired is the better and more expensive option. A fellow on another forum had the external unit attached to the power pedestal. His plug shorted where it entered the rig causing 220v to get inside. Since all this happened downstream from the EMS, it didn't know the difference.

Ouch! Was hoping the external would be just as good but easier to replace. If there are problems downstream guess the hardwired right before the fuse panel is the only way to go.
