For those using Victron BMV-712. I have 8 HB 6-volt AGM batteries. The label says that they are 210AH, so I figure I have 840AH total. The BMV-712 set up instruction ask for battery capacity (preferably use the 20-hour capacity rating (C20)). Would that be 840 or what is the C20 rating and how do you figure it out?

Marc,

That is what you want...840 would be the correct number. That is your 12v 20hr rating.

He recommended disconnecting the Precision Circuits panel from the Magnum Network. He said the Precision Circuits was designed for use with the ME-RC50 remote and ME-AGS and would likely be troublesome with the ME-ARC. That along with the giant size of the PT-100 charge controller left me to abandon that idea. We have pets...and the soft start feature for the AGS is a feature I refuse to disable. We arm AGS with the Dometic controller linked...and it works beautifully should the shore power go out. I like the other features of the Precision Circuits EMS as well...I just can't justify disconnecting it from the network.

So...I've decided to go with a Victron charge controller with it's own control panel..,plus it can be programmed/monitored thru a smartphone app using built-in BlueTooth. I have my ME-BMK installed. My Precision Circuits EMS is still playing nice with the BMK in the system. Now, I still would like to change Magnum Remotes.,,to take advantage of the State of Charge Auto Generator Start feature. Have you found that In that configuration...the Precision Circuits panel will still play nicely with the MS2812, ME-ARC, ME-BMK, and ME-AGS-N??

I guess I need to call Precision Circuits to see what they know about it before ordering a new MEe-ARC Remote. Like I say...the features the EMS when networked to the Magnum Network is a big bonus in my mind!!!

Thanks for anything you know regarding that setup...

Charlie,

Are you using Magnum ME-ARC if so do you still have Precision Power Control system networked to the MS2812 inverter? I just called Magnum and they said it doesn’t play well with ME-ARC. I have version 5.1x PCS.

I have monitor v5.15 and control v5.19. I am under the impression they have had two different wiring methods. One had the ME-RC go to the load center, and daisy chain to the inverter. The other, like mine is wired so the remote goes directly to the inverter, and the load center has it's own network cable going to the inverter. I don't know what it is I should be looking for as far as not playing nicely. I haven't had any problems. I did install the ME-ARC...and did leave the Power Control System networked. I don't get into a situation very often where it has to do much...the Tampa SuperShow NKK rally is about the only time I have had 30A shore power. Most other times...I have either had 50A shore, or dry camping...no shore power, and AGS set to regulate temperature when needed. FMCA rally in Perry, GA and Albuquerque Balloon Fiesta were good dry camping experiences.

On my 2019, I have the PCS v5.15 & v5.19 as well.

I installed the ME-ARC & BMK. I have tested the inverter assist, charger cutback, and auto gen start functions. All work as they are designed. When I did the inverter assist, I connected to 30 amp service and ran the a/c with charger. I was pulling 28 amps. I then turned on AC1/2 on the oasis and the charger was reduced. Total amp draw spiked, and then dropped to 26amps. The ems had disabled leg 2 of the oasis, and reduced charger load to 5 amps.

After this in then started the microwave. Total amp draw was 39amps, and the inverter assist was adding amps to the load.

Finally, for gen start, I used the manual controller to start the gen via the magnum arc menu.

There may be a future issue, but so far it is working for me.

I did run the network cable back to the AGS, and added the telephone splitter there.

My inverter is the MS2812

If your ME-RC has no communication issues with the BMK installed, the ME-ARC should work fine. Up the PCS is not wired correctly in the network, you would see communication issues with the ME-RC.

Red Baron when you did the test did you have AGS set to Auto. The pass couple of night on 30amp the generator keep starting instead of reducing amps.

So you moved the ME-ARC or the PCS from the inverted to the AGS.

I also tested auto, and used the temp ext input as the trigger. That worked too. Normal usage, you should have ags set to off. Only set to auto when you need a fail safe or plan on usage.

When fail safe, I use the soc as the trigger. No other triggers set.

I didn't change either of these connections. These are wired to the remote port on the ms2812. I needed to connect to the network, but since there was no room for the phone splitter in the inverter, due to the remote port using a splitter already, I had to run a longer cable from the me-bmk to the me-ags-n. I removed the existing network cable, installed the splitter, and reconnected the network cable going to the ms2812. In the spare port of the splitter, I connected the cable going to the me-bmk.

Red,

You reinstalled all this during your FPU? Any assist from Newmar tech?

Quick note about the networking...

The ME-BMK comes with a splitter. And there isn’t room for it to fit next to another splitter. I used a short dongle and splitter port from Home Depot. When I hooked it all up, my ME-BMK wasn’t showing up.

I figured out that the dongle I had purchased...for a telephone/answering machine...doesn’t worry about the wire orientation. The remote wiring depiction shows how the wires have to be oriented for the Magnum Network. Once I cut one of the ends off...and reinstalled a connector with the wires oriented properly...the thing worked like a charm.

This little device allows you to wire the network in the STAR configuration...if you want, vs going to the ME-AGS-N to hook in there.

The days end at 1:30 during FPU, with your coach delivered back to your site by 2:30p. Leaves plenty of time for making changes.

That is a brilliant idea! As it was, the included cord was not long enough to make the run to the ags.

I also installed a surge protector, the ems-hw50c. This included a cord for the remote that was long enough to reach the ags. I had to replace an end on both cables to correct the pin orientation, as one was a crossover and the other was a straight thru.

Definitely do not use the splitter brick. I did and it worked for about a year then my AGS would fall offline, etc. etc. For me I needed two of these, one at the inverter, one at the AGS in the way I wired up my BMK, etc. These work great and I also used the cable ties with the screw hole thing to secure the wires.

No need for messing with the wiring, just plug it in and it works.

Well I guess these are coming from a new Chinese supplier. I ordered them & neither worked when I installed the BMK today. If you need a splitter DO NOT order these!

Now the search begins to find dongle splitters that are wired correctly for data applications.
