Can I use a "Cerbo GX + GX Touch 50" instead of "Digital Multi Control 200 + BMV-700"

Hi, I am installing a new system with the core components being a Multiplus 12/3000 inverter/charger, 2 x LiFePO4 Smart Batteries (12V/200Ah) & a VE.Bus BMS. I have been recommended to include a "Digital Multi Control 200 + BMV-700", but I'm wondering if it would be better to replace those 2 items with a "Cerbo GX + GX Touch 50". I would like the ability to monitor/control things remotely, and I have read (in other posts here) that you cannot change any settings remotely (nor via the touch panel), that can be set via the physical switches on the DMC (which takes priority).

So my question is really, can you do everything via the Cerbo GX & Touch 50, thus doing away with the need for the DMC & BMV altogether?

Using existing RV 4 wire cable to Victron Energy Digital Multi Control 200/200A GX

I just installed a Victron MultiPlus II 3000 and now looking to install a Victron 200/200A GX Digital Multi Control GX. My old Xantrex system used a 4 wire telephone style wire from the Inverter to the Display Panel. I'm aware that you can use 4 wire for Ethernet Connections. I would like to remove the old RJ11 connectors and install RJ45 connectors. My question. Can I use the standard ethernet connection for this installation (Using Pins 1,2,3 and 6 in the RJ45 connector). Or does this use different wires. If possible I'd rather not snake a new cable from the back of the RV all the way up to the Panel above the windshield if the existing wiring can be used. . Any help would be appreciated.

Inverter on, DMC off, AC mains still getting power

Setup: In a Sprinter, converted to camper summer of 2020, I have a MPPT 100-15 smart solar controller charger, a non isolated 12-24-15 DC-DC charger, a 24-3000-70 inverter/charger, a 24-12-70 converter, a multiplus color control GX retail, and a digital multi control (the model with the toggle switch and the rotary limiter control switch); all Victron equipment.

All settings on all the equipment are as the van builder set them.

About three weeks ago, the 12-24-15 DC-DC charger stopped charging the batteries. App alternately indicates engine shutdown detected and/or, input/out-put lock out.

While I cannot confirm the precise timing, this problem (DC DC not charging batteries) occurred after testing the power mode (as opposed to the charger mode), while driving.

In the process of trouble shooting the lack of "alternator" charging and dealing with a sub-zero Artic Blast and the van not being winterized panic, I noticed the DMC was not illuminated when switched to charge only and connected to shore power to run heaters. Oh well, I thought, LED's burnt-out; mains were working, look into it later. Warmer temps are here and later is now. Discovered that with inverter on, but DMC off, mains still get power. This is obviously not right and increases the parasitic drain and with cloudy days predominant and alternator charging not working, batteries are only getting solar charging.

That's the back drop. The short question is: with DMC in off position, why are AC mains getting any juice?

To reiterate, this is not a new build and I didn't do it. Im a total dummy when it comes to all things electrical. Nothing in the setup changed in ~2-1/2 years.

Issues changing from Digital Multi Control to Cerbo GX

I am replacing my Digital Multi Control with a Cerbo GX and a GX Touch 50. Everything worked fine with the DMC, but when I remove it and replace it with the Cerbo GX, my Quattro comes on but keeps turning off and on about every 5 seconds.

Digital Multi Control - 200/200A vs 200/200A GX

Hi there!

Besides the difference in price and look, I'm wondering what the functional difference is, between the
Digital Multi Control 200/200A
and the
Digital Multi Control 200/200A GX

Thanks in advance :)

Current limit display won’t turn off on Digital Multi Control

I have a DCM connected to a Multiplus 12/3000/120. I also have a VE Bus BMS and an Octo GX. Recently I installed a VE Bus Smart Dongle and although the Multiplus seems to operate correctly when I turn the DCM switch to Off all the lights go out except for the numeric current limit display, this now stays illuminated in all three DCM switch positions. How can I restore the DCM to normal operations?

Digital Multi Control - not able to set current limit over 7 amp

Digital MultiControl 200A GX
Quattro FW 2634497

Using VEConfig or VictronConnect settings I cannot make the 16A current limit "stick" in the settings when I select "overruled by remote" when the Multicontrol is connected.

Any idea?

Digital Multi Control - Inverter Only

Setup: The DMC is connected to the Multiplus-II via RJ45-UTP. A Lynx Smart BMS 500 and a Cerbo GX are part of the system.

The DMC offers the following settings: Charger only, Off and On. When the physical switch is set to "On", it activates the charger and the inverter at the same time.

Is it possible to configure the DMC in a way that the Multiplus-II is set to "Inverter Only" if the physical switch is set to "On"? I don't want to enable the charger at the same time. Current workaround is to physically disconnect A/C input to ensure that only power from the batteries is taken and not from the grid.

Thanks a lot,

DMC 200/200A with non-parallel MultiPlus

For anyone not familiar with RV shore power (at least in the US/Canada), there are two options - 30 amp and 50 amp. 30 amp is entirely straightforward - 2 wires plus ground, 120V 30A across the two wires. 50 amp should really be called “100 amp” because it is three wires plus ground, so there are two “legs” with 120V 50A across each leg (100A total). You could run 240V appliances across the two hot wires, but there are no 240V appliances in my RV, so each leg originally attached to 1/2 of a split breaker panel, with half the appliances on each leg.

When I added the batteries/solar/inverters, etc, I installed two MultiPlus 24/3000/70 inverter/chargers, one attached to each shore power AC input leg. I then attached the AC output of each MultiPlus to 1/2 of the split breaker panel. So even though I have two Multiplus units, their outputs are not connected to each other. I.e., it is neither a split phase nor parallel installation. The only connection between them is the connection to the battery bank.

I now wish to add a DMC 200 control panel so I can quickly adjust the input power limit when I attach to a generator or 30 amp shore power. In both cases, a dogbone connector sends the single phase 30A power to both legs of the 50A shore power connector, so I need to set the MultiPlus input power limit to 15A each to avoid overloading the generator or popping the shore power breaker.

(finally) My question is: Can I connect the two MultiPlus units together (master/slave) via RJ45 and then attached a single DMC 200 to the master even though they are not connected in a parallel or split-phase configuration? Put another way, is it OK to connect the two MultiPluses with RJ45, even though their AC outputs are not connected together?

programming DMC with a Multiplus 3000

Trying to configre the DMC to set a current level for my genset that is higher than my shorepower setting (V.E. Bus Multisystem+external transfer switch). I have initially used VEconnect to set up the Multiplus parameters. With the DMC and Multiplus on, when I push the button on the back of the DMC to start the programming nothing happens-no flashing LEDs. What am I missing?

Digital multi control. GX or not?

My system will have a Multiplus, a CCGX & a ve bus Bms. The Multiplus will not be easily accessed. I want to be able to turn the inverter off/on remotely. Can I do this with a Digital Multi Controller plugged into the remote port in the ve bus Bms? If so, do I need the GX version or a standard Digital Multi Controller?

Cerbo GX with Digital Multi Control - any benefit of having both?


I am installing a Multiplus II on my boat. I already have installed two MPPT solar chargers and a Smart Shunt. I have bought both a Cerbo GX with the 50 touch display and a Digital Multi Control for the Multiplus II. I realize that some of the Cerbo touch functions are disabled and controlled by the Digital Multi Control if both are connected per section 2.4.1 of the Cerbo manual.

My question is this: Do I need the Digital Multi Control if I have the Cerbo GX with the 50 touch display? Is there anything that the Digital Multi Control can do that the Cerbo GX with the 50 touch display can not do?

Thank you,

Flashing LEDs on multicontrol when in 'off' position
Hi all
Just finished setting up my Multiplus 12/3000/120 with the digital multicontrol remote.

When the unit is switched off via the multicontrol all the LEDs on the multicontrol flash rapidly. They are fairly dull however.. The multicontrol works as it should otherwise and the multiplus responds correctly (shutting off when this occurs). It is fine when turned on or 'charger only' and only the appropriate LEDs are lit..

I have tried different cables and updated the Multiplus firmware.

It functions completely normally when I tried unplugging the Multiplus from the Cerbo but then the above issue happens as soon as it plugged in again

Had anyone come across this before?

Multiplus, Digital Multicontrol and Cerbo GX


When I connected the Digital Multicontrol AND the Cerbo at the same time to a Multiplus 3000 it stops working.

If I only connect one of the 2 it starts working again.

Is this normal? can I only connect one of the two? any tips.
