Energy Management System question...

Hi, All -

I have a 50 Amp Progressive EMS on my current gas coach. A brand new diesel coach (hopefully mine soon!) already has an "Energy Management System" listed in the specs.

So, I don't have to move my current Progressive unit to the new coach then, since it already has one - correct? I'm thinking likely yes, but didn't want to make a newbie mistake there...

Thanks!

I'd check that closely! What they are referring to may just be a system that detects the source you are using, and "sheds" off loads to match the available power. Our coach has that, but it offers no protection like the PI EMS system does!

exactly. the EMS has nothing do with monitoring the quality of the incoming electric (high voltage/low voltage/proper CPS/spikes, etc). it will monitor consumption (amps) and auto-shed loads in a prescribed manner to prevent tripped breakers inside the coach as well as the main post. you should consider adding the surge protector.

My choice would be the Progressive Industries HW50C. Don't leave home without it.

I agree with all above. Progressive is needed and the way to go.

Don't leap to any conclusions yet. Many new coaches are coming with power line protection as standard equipment, so that standard "EMS" may (and I emphasize "may") do everything your Progressive does. You need to ask more questions about exactly what "EMS" is in this new coach. Heck, my 2004 coach had it as standard.

X2. Ask questions.

Gary - good point too. Was looking through the brochure and it says (as standard equipment) that it has "Surge Guard" electrical system protection. I'll definitely ask. Thanks!

Just add: Progressive is guaranteed for life; EMS warranty 1 to two years depending on brand of coach you buy. I would stick with the progressive for life brother!

My two cents worth!

I agree! Even if it has some protection built-in, it may not be as effective as the Progressive Industries. You certainly can't have too much!

What harm might occur if the Progressive EMS was wired into the new coach in conjunction with its built-in system?

Most coaches don't have a fully featured electrical monitoring system out where the shore power interfaces with the coach like the Progressive EMS unit. Many have some degree of surge protection. A few have some low voltage protection. Usually, the term EMS in a new coach stands for "electrical management system and functions to shed loads when a 50 amp coach is plugged into 30 amp shore power.

These systems usually play nice together, but if you want to be sure, call Progressive & tell them what you have in your coach. They will give you a reliable answer.

I don't see how it could possibly cause any problems! JMHO......
