Actually there is no need to use an EMS with a generator ...
Which misses the point entirely. This isn't about whether one "needs" to use the EMS when powering from a genset or inverter but rather "can" we? Sure, problem solved instantly for anyone using a portable unit that normally hangs off a campsite power post but for those of us who have installed a hard wire EMS into our units it's much more problematic. I'm one who did give this some thought beforehand and therefore wired my Progressive EMS-HW30C into my rig using 30 amp connectors so I can, if need be, totally remove the EMS from the incoming source line when powering from my EU2000i or my inverter. Yes, I could have also wired in a transfer switch that would accomplish similar results but for me, considering the limited number of times I might not run on shore power, it's just not worth the expense or effort involved in wiring one in. The point is, it would still be much simpler if I didn't have to do anything at all regardless of which power source I was using ... and THAT'S the point we've been asking Progressive to clarify. It may not be the way in which Progressive intended their EMS units to be used but it is reality so it's only in their best interest to address these concerns with more concise answers ... until they do discussions like this will continue because too many EMS owners don't have a clear understanding of when these units can safely be used and when they can't.
