Victron: control head

I have the following victron items

Cyrix- battery isolator
Shunt and BMV702 Btooth monitor
BP-100 battery protect
MPP solar controller 100/30

i did not want to add a separate status/control monitor for each as i only have so much free wall space

so I found "Color Control GX" on sale on ebay NEW
much better price than a local dealer or amazon

The Color Control (CCGX) provides intuitive control and monitoring for all Victron power systems. The list of Victron products that can be connected is endless: Inverters, Multis, Quattros, MPPT solar chargers, BMV battery monitors, Lynx Ion + Shunt and more

Did you buy the BMV-702 or BMV-712? The BMV-712 is the newer model with built-in Bluetooth, the BMV-702 requires adding a Bluetooth dongle to enable it for BT.

Have you planned out how you are going to integrate all of this together? How are you planning to integrate the BP-100? As a low voltage disconnect? Why not just rely on the one built into the BattleBorn?

There was a discussion not long ago on the CCGX, if you didn't see it: http://www.airforums.com/forums/f449...rs-161855.html

i mounted my monitoring devices above the fridge in my sport 22FB
They are all mounted on a 1/4" plywood board, i made a small 1" frame around to hide the wires

i also beveled the bottom so that the bottom face is on an angle and so that the top edge can touch the wall, that way i can place 3M VHB tape on the bottom edge and the upper edge to keep the panel solidly in place

the various wire either go:
  • down , to access ac power
  • left , signal cables and cat5 wires that go through the pantry and under the whole kitchen area to head towards all the power electronics under the bed road side
  • up to access DC supply from the AV centre

to prepare for winter
i removed the BB LION battery
and reinstalled the factory Lead acid

i also reprogrammed the BMV712

here are the proper summer Lion setting

the only changes i made for lead acid were
  • peukert 1.25
  • charge efficiency 95%

if anyone knows of any other changes i should make to maintain the system with Lead acid battery , please post here

Hi

If you are going to keep all of the "smarts" running through the winter, you should keep the trailer on some sort of power source.

Ideally for a lead acid in cold weather, you would want a temperature sensor on the battery and a feed back into the charge system.

Hi Bob

it is is on ext ac power
i did not want to run ext ac without a battery
as i am not keeping heat inside, it did the plow out followed by antifreeze in the traps

i want to do some work over the winter , thus want to maintain the system operating, s once the cold is gone in the spring, the BB lion goes back in

thus i am now asking for BMV 712 battrey settings for the lead acid battery

That's interesting...

One of the reasons I got the BB's is so I wouldn't have to remove for Winter storage.
I guess I just understand the same things differently. 😂

No drop, steady since put in storage.

Hi

Spend the extra couple bucks on the temperature sensor and patch it into the system. Then set the charger up to use the temperature information. Since there are two sensors and two ways to integrate them this becomes a "that depends" kind of thing. Once goes on the 712 and gets set up there. The other can go into the control head or into the Multi Plus and gets set up accordingly.

The same "it's too cold" (as in < 0F, 0C fine for BB's ... yes, I've been in Ottawa in the winter ...) thing applies to battery charging. Keeping things lined up properly is important. A totally dead battery at 0F looks a lot like a fully charged battery at 70F.

Hi

Ok, then you should (as part of changing the settings) make sure that temperature compensation *is* enabled. For many lithium setups, you disable temperature compensation.

Does anyone know if the existing Cat5e wire that comes with the factory solar package running from the Atkinson controller will work with the BMV-712? My goal is to replace the controller with a Victron MPPT 100/30 and connect it to the BMV-712 using the existing Cat5e cable that runs to the old Sunexplorer II display unit.


Thanks!

yes

cat 5 or 6 is fine

just cut off the ends or use and adapter to reuse the rj45 to the victron 4 pin connector

the connectors are cheap on amazon, but you need a good crimping tool for the small pins

its best to use stranded cable for the last metre as the small connector are very fragile and the solid wire on cat 5 may cause them to break or come loose. that's what i found out

Awesome, thanks! I was worried I would have to run cable. I much rather crimp wires!

Hi

Much easier to just get the Bluetooth enabled version of the MPPT and do it that way. You can also add a dongle to the "old" MPPT, but that costs more money. You do a couple of clicks on each device to "create a network" and then they do the same chat over Bluetooth they would have done over the cable.
