Electrical Management Systems questions
I'm considering installing a hard wired EMS. I recently saw a thread, that I can't find again, that implied these EMS systems will not work with an inverter generator supplying the trailer. I real...

I understand, regardless of the issue, why bypassing the EMS would work, but that seems like a lot of work.

PI actually used to sell a pre-made plug to plug into generators similar to the illustration above. (I have one, and use it on a small faux Yamaha inverter genset.)
The EMS will not allow unbonded neutral power into the coach as part of the protective schema. The plug simulates a bonded neutral on the generator.
Or, as I mentioned, I can bypass the EMS and allow the genset to power the coach, but that eliminates the protections of the EMS.
