Need to add EMS, none installed on older hulls?

[jd1923]

Watched the OU video on the EMS system. Noted a post where @John E Davies mentioned the display may be mounted under by inverter. My 2016 hull #113 does not seem to have one. No display in the rear attic and none to be found. I can see the incoming power going directly to the PD5100 without EMS before or after.

Thinking I should install one. I'm not the guy who plugs in external devices and blue water filters at the camp site! Thinking I should install this one correctly. Is this what OTT installs? Amazon.com: Progressive Industries RV Surge Protector 30 Amp with Electrical Management System, Hardwired with Remote Display, EMS-HW30C : Automotive

I'll bet @Scuba Steve knows the history here or perhaps @topgun2, since Bill's Oliver and mine are cousins (hulls 113 and 117).

I imagine the EMS needs to be installed near first in line, just after the PD 5100 which switches between the two built-in shore power sources. Let me know. Thx

Yes, that is the same model PI EMS installed in my OTT.

jd1923 - 

Given the amount of electronic "stuff" in the Oliver, I simply chose to have this system installed at the time of birth.

It has worked perfectly over the past years, but, I've never really looked to see exactly how it is installed (with the exception of that remote readout).  Unfortunately, Twist is in off-site storage or I'd get some pics for ya.

Note that the readout was initially installed under the street side bed.  This meant that in order to see what it was trying to tell me, I'd have to lift that bed!  Be careful as to where you decide to mount it - the flashing (as it scrolls through its various screens) will make you think that you are trying to sleep in a cheap hotel if you mount it just about anywhere out in the open part of the cabin. However, you will want it in a place where you can see it easily as you plug into shore power.  I moved mine from under that bed to inside the pantry - it is high up on the rear wall of the pantry.  All I do is open the pantry door and I can see the readout from the entrance door, yet, it is not in the way of storage inside the pantry and, when the door is shut that flashing red display can't be reflecting off the interior of the cabin.

The EMS in our 2019 EIi is installed under the rear dinette seat on the wall facing the aisle.  This pix is looking down under that seat.

 

The readout is mounted in the attic on street side wall.

My 2010 Hull 45 did not come with any type of surge protection either. Used one of those pedestal types for a while but recently installed a hardwired Hughes Autoformer with surge protection.  So far it seems to be working as advertised and I like the fact it can be monitored with bluetooth and that it's DIY to replace the surge protection module should it fail.

Our 2018 readout is mounted on the street side wall, to the right of the pantry, above the Fresh/Gray/Black/LP sensor readout.

That's a great place for seeing it from the entry door, but, doesn't the "flashing" red light bother you at night?  Or, did you find a way to tame it?

Frankly not enough to get out 1/2" of black electrical tape.   But when I did the Lithium project, I moved it to below the bed rail so I could put the Victron 712 smart in it's place.  Under the bed rail it for sure does not bother us. 

More often though, I have seen it mounted on the StreetSide rear tire fender facing the "hallway".

Great move, Bill!  Seem to remember reading about this mod. in previous posts - we'll definitely mount it high up inside the pantry...  Another item for the "To Do" list; thanks!

Cheers!

Thank you @Galway Girl. It may be hard to capture another picture, though a good picture of the connections would be great! Can anyone explain the OEM install? Are the incoming wires coming from the output of the PD5100? (The PD5100 is the shore power ATS.) Does the outgoing cable feed the PD4000 Power Control Center (containing the 120V circuit breakers)? Newer units may have newer PD model numbers, but all would have an ATS (automatic transfer switch) and a 120V AC power panel. This would be my guess, if I were to install this, but wondering how OTT does it at the factory?
