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...

Hi Bobbo,
I can see a use for EMS with 50 amp. With 30 amp--not so much.
I have superior surge compared to what is available and use an Autoformer (boost and buck) to take care of low voltage.
I do have a way to limit my demand to 80% of what is available, so on 15 I limit to 12, 30 to 24, and 50 to 30.
An EMS to me would simply be another potential failure point.
I always check voltage under load and polarity before plugging into an unknown source.
Differing opinions are what make life interesting. You follow your muse and I will follow mine.

If one is paranoid about the extremely unlikely chance a generator could somehow fail in a damaging way, have at it and wire your EMS to include it, as outline in the many responses above.
Thank you. I think I will. And while I am at it, I will allow my paranoia to force me to carry fire extinguishers too.
(BTW, rather than call it paranoia, I prefer to call it being cautious. Maybe overly so, but I have never had a severe problem if I was being overly cautious.)
This is an open question to all who think the generator power should not go through the EMS. I have heard many times that it was not necessary. My question is, what harm can it do? If it is even potentially helpful and can't be harmful, then why not? If it can be harmful, how?
