I have a 2017 Cardinal with 3A/C's and I have a "energy management" panel on my control panel. I have no idea what it does, other than do load balancing when plugged into something less than 50AMP? Do I get the protection already? Or do I still need this unit?
Just the other day I read another forum discussion about this but failed to bookmark it :S ... unfortunate because the details clearly detailed why these included factory installed "energy management systems" are a completely different animal from the surge protector / EMS units we're talking about here in this discussion. Without specifics about your particular system I'd say yes, you want an external EMS such as the Progressive Industries EMS-PT50C or EMS-HW50C.
So it's very similar to this: http://www.precisioncircuitsinc.com/wp-content/uploads/2014/08/00-10024-000-Power-Control-System-Mini-D1.pdf
Except mine is W/H, A/C RR, A/C-FRT, and A/C-MID. I'm pretty confident that the EMS that came with my cardinal is to manage the high draw items when running on less than 50A service.
EDIT: I've sent Progressive support some email, and we'll see what they say. I suspect it will still be a good thing to have, just want to make sure there will be no issues with both coexisting, and no overlap in function.
