DMC needed with Cerbo GX, Gx Touch 50 with Multiplus 12/2000???

As the title says, everytime i chop and change my equipment selections for my upcoming RV build, im presented with more confusing aspects.


Do i need the DMC with the above mentioned components if im using a VE.Bus BMS or has that been removed now? Can i control the Charger only/On/Off portions with the GX Touch 50 or will i be required to install another component, that being the DMC???


System will also have MPPT, smartshunt, 2/3 x lifepo4, smart battery protect

CCGX/DMC not updating with new MultiPlus current limit setting

System Components:

MultiPlus 12/3000/120-50 120V (FW 418) with VE.BUS BMS

CCGX (v2.58)

DMC 200 GX

BMV-712 Smart (v4.03)


I just added a DMC to a system that has been running 2+ years without one. The goal is to have the DMC allow a 1-30A adjusting range with the Multi defaulting to the lowest level


I lowered the input current limit in the MultiPlus (using VEConfig) from 9A down to 1A using VEConfig. I have verified that the MultiPlus is set to 1A after power off/on.


Regardless of what I do, the CCGX and DMC still thinks the current limit is 9A. I programmed the DMC for the upper 30A limit. The DMC works just fine adjusting the current limit >= 9A up to 30A. It just will not allow it to go lower than the old 9A setting.


I did try redetect system the Multi on the CCGX with no luck.


What's the magic to get the CCGX/DMC to see the new lower 1A setting in the Multiplus?

Ve.bus multi switch not working


[image]

So here is my multi control connected up to an old 19xx multiplus which is plugged into the mains. Annoyingly, although it's reading the info correctly from the multiplus, the switch doesn't work. It won't turn on or off remotely at all. It used to work last year though. Thoughts?

Digital Multi Control GX w/ remote on/off

I have a DMC that I was hoping to use with my Multiplus, and later a Quattro when I upgrade. However, I am using 2 remotes from my BMS - one to turn off the charging when the battery is full or when it's too cold, and another to disconnect load if the battery gets too low. I came across this is the Multiplus manual though: "Only one remote control can be connected, i.e. either a switch or a Multi control panel."

Strangely, that does not seem to be mentioned in the Quattro or DMC manuals, but I presume the limitation is the same for the Quattro.

I wanted to confirm whether there was no way to use both together. My expectation was that the BMS remote on/off would override whatever was set on the DMC remote, which would be ideal. I can wire simple switches in line with the BMS remote to get remote switches for the inverter and charger, but I was really hoping to have the input current adjuster on the DMC available to use, since otherwise I have to connect a computer to MK3 to change the setting.

I'm curious to hear any feedback/ideas. Is there any way to have both BMS remote on/off control and ability to adjust input limit without using a computer to do it?

What do two flashing leds on the digital multi control indicated, after programing, the absorption and float lights flash.

The Digital Multi-Controller, when switched to charger only, shows a blue led, connected to mains, then a blank led for bulk, then flashing yellow for the absorption and float.

EasySolar 24/3000 & VE.Bus BMS - Do I need a Digital Multi Control?

Hi there!

I have the following units (not connected yet)

EasySolar 24/3000 (includes a Color Control GX)

2x 12,8v 200ah LiFePO4 Lithium Smart Batteries

VE.Bus BMS

The VE.Bus BMS manual says it requires a Color Control or Digital Multi Control
It also says don't connect the control panel directly to the Multi or Quatro (signals from the control panel may be in conflict with signals from the VE.Bus BMS)

So I'm wondering if the Color Control on the EasySolar is the only control I need
Or if I also require another control connected directly to the BMS ??

Thanks very much in advance :)

Digital Multi Control - not able to set current limit over 5 amp

I have a MultiPlus 24/3000 (Firmware 469), using a Digital Multi Control to remotely limit the current.


In the past I had no problem switching currents between 5-16 amps. Now however the current limiter is only allowing a maximum of 5 amps. I have tried changing the settings on Shore limit. Turning off "Overruled by remote" does display Ac 1 on the DMC, and does allow me settings over 5 amps. Any settings I try with "Overruled by remote" enabled does limit me to 5 amps, both in "Charger only" and "On" mode.


What could be the cause of this?

Ve.Bus RJ45 cabling order

Is there a proper order for cabling the following Ve.Bus devices?
(Usually with a 'bus' order doesn't matter.)

DMC GX (required for current limiter when using a Ve.Bus BMS)
Ve.Bus BMS (required for Victron SmartLithium batteries)
Ve.Bus Mains Detector (to allow for DC start when AC is present)
Inverter/charger 1 (split phase)
Inverter/charger 2 (split phase)
CCGX

In a full Ve.Bus chain of devices, the Ve.Bus BMS manual suggests that there is a preferred order (page 4): https://www.victronenergy.com/upload/documents/Manual-VE-BUS-BMS-EN-NL-FR-DE-SE.pdf

[image]



This leads me to believe that there is a required Ve.Bus order of devices which with this equipment list would be:
DMC GX -> Ve.Bus BMS -> Mains Detector -> Quattro1(leader) -> Quattro2(follower) -> CCGX

Can Victron confirm this order requirement?

I guess this leads to a bunch of other related questions such as:

Do the specific ports on the Ve.Bus BMS have to be used as labelled?
Remote to DMC GX, and Ve.Bus to the Mains Detector, before the Inverter(s)?

Is there some unspoken addressing conflict if these are wired out-of-order?
Is it that the DMC is on the same address as the CCGX, where we are hiding the DMC behind the Remote port on the Ve.Bus BMS is required?


The DMC manual seems to suggest that you can connect it directly to an inverter which indicates its a Ve.Bus Device, but the Ve.Bus instructions indicate otherwise.

Is DMC GX still required for systems with Ve.Bus BMS for changing input current limiter?

Is the DMC GX still required for systems with a Ve.Bus BMS for changing the input current limiter?

The CCGX manual suggests that the DMC GX is still required if you have a Ve.Bus BMS:
From: https://www.victronenergy.com/live/ccgx:start#vebus_inverter_charger_monitoring

Are the current limit settings, which are now present in the CCGX, sufficient for for controlling input currents in systems with Ve.Bus BMS batteries without the need of a DMC GX?

Is the Digital Multi Control still required with a CCGX+MultiPlus?

When I built a Victron system on my boat about 2 years ago with a MultiPlus, Victron LiFePO4 battery and VE.Bus BMS, you had to have a DMC connected as well if you wanted to set shore side power limits, as the CCGX would not allow you to do so.


I thought I remembered seeing that this was ONLY the case with the VE.Bus BMS, which I am not using in a new install, and potentially not required at all anymore with a recent CCGX firmware upgrade. Can anyone confirm this?


To be clear, the components I would be installing Victron-wise are:

  • MultiPlus 12v / 110vac / 3000w / 120a charge
  • CCGX
  • BMV-712

Color Control GX and external transfer switch

I am currently using a MultiPlus with Digital Multi Control GX. I use the input of DMC for integration with an external transfer switch (for grid and a genset - since they have different power capabilities). What I would like to add is remote monitoring and control, including the possibility to remotely change Multi modes (On/Off/Charger). I was thinking of adding a Color Control GX, but I have concerns. The problem as I see it is that if I keep the DMC in the system, the On/Off functionality in Color Control GX will be disabled, and I will not be able to use it remotely. If I remove the DMC, there will be no place to connect the input from the external transfer switch - since Color Control GX does not seem to provide this functionality. Is there a way to solve this and have both remote monitoring and control and integration with a transfer switch?

Connecting to 120 shore power trips breaker

Have a Multiplus 12/120/3000 with 4-100 amp hour Lithium batteries in series installed in our fifth wheel trailer. Everything has been working great and as it should, but I recently tried to plugin to a standard 120 wall outlet just to trickle charge the batteries while parked in a friends driveway and it would trip the breaker. I tried turning off everything via my breaker panel in my trailer that wasn't necessary to see if it was a load issue...still trips. I also played around with the current limiter settings on my victron digital multi control...nothing made a difference. Multi control was set to charger only. Has anyone else had any issues like this? Maybe something else I can look into to try. Please advise? Thank you in advance :)

Multiplus and CCGX DMC and VE Bus disconnect

The site has 3 multiplus units all on 459 firmware all in parallel

the site works fine using the DCM or the CCGX NOW but connect both and the DMC works fine but the CCGX keeps dropping out and then back on then out again

by this I mean it shows the correct infor then the info drops out and the display says OFF, however the DMC still stays working and so does do the inverters

I have tried new cables and changed them ALL to Cat 6 Cables with plastic plug ends

History

1. first of all I installed the CCGX to the site with the DCM connected and all worked well. this had a 20 mtr cat 5 cable from the inverters to the ccgx then a 1 mtr to the DMC the CCGX on 2.23 FW

2. then I changed the inverters battery cable lengths so they where all identical

3. I then upgraded the firmware from 419 to 459

After the above had been done

The CCGX would not connect AT all and I also could not get a connection with the MK3 but the MK2 would work.

I then ran a temp new victron cat 5 - 10 mtr cable and the CCGX would then work but connect the DCM and the CCGX would go off line, use a 5 mtr cable and all worked fine, but this is way to short and I cant leave it like that on the boat.

I then had the original cable shortened to the Min length I could get about 9 mtrs, and the inverter interconnects also replaced with cat 6 and shortened it min lengths posable.

in the end to even get the CCGX to work on and off on off etc I shortened the ve bus internect cables and this then allowed the CCGX to work abate not to well, I even tried putting it up to the release candidate firmware as well

Now the CCGX works in and out when the DMC is connected but fine on its own.

*******

My suspicions are that the VE bus signal from the inverters has decreased in output power somehow, with the firmware upgrade.

the site is available via VRM if needed its setup as B2 on my site list plus the DMC is not currently connected so the CCGX and the VRM are working fine.

Note the CCGX is using the victron wifi dongle

Any one got any fancy ideas or tips

Problem connecting Digital Multi Control to Multi 12/3000/230

I'm trying to add a DMC to an existing working system but when I connect the RJ45 cable leading to the remote panel the system shuts down. If I unplug the cable the system returns to life. Toggling the switch on the remote has no effect.

I've tried removing the short (small cable) that is connecting the left and middle points of the manual switch but that results in the system shutting down completely, remote or no remote.

The main switch on the Multiplus is set to 'on' as per the manual.

I'm using Cat 6 cable with 2 x RJ45 connectors.

Am I missing something?

Digital Multi Control GX can't throttle the AC input low enough

Hello from a US authorized Victron dealer. A newly commissioned system has twin 5k Quattros stacked parallel for 120vAC & using only AC1 for input...nothing connected to AC2 IN. Both Quattros have the latest firmware as of December 2018. Client has the Digital Multi Control DMC...set with the pushbutton on that unit for no more than 30 amps AC in...& in VEconfig we authorized the Remote to "overrule" & determine the shore input amperage. Dialing the radio knob, the digital display is either 30A or 27A, however--not much of a range. We want to be able to adjust for a smaller shore breaker.


The client also owns the Color Control GX & I see the AC IN appears adjustable within the CCGX menus. If we de-commission the DMC & use CCGS for this tweak instead, would we get better granularity on this adjustment & a smaller bottom number?


Other suggestions on how to help my customer in this situation would be greatly appreciated. Thanks & Jolliness~
