VictronConnect differences in screens "Demo" vs Actual on MultiPlus

Hello Everyone,

In my MotorHome I have the following Victron Equipment:

Multiplus 12/3000/120-50 120V

CCGX (w/DVCC turned on)

Plus Smart MPPT's

I also have some lithium batteries and I want to put low temp protection on them. The Mppt's were easy - done! After researching for the Multiplus I was pointed to that option being available in the "Demo Library" version of Victron Connect - So I just purchased and installed the VE.Bus Smart Dongle onto the Multiplus.

However the screens are completely different and I don't have access to the screens that will allow me to change the charger settings:

Demo Library Screens:

However when I installed the VE.Bus Smart Dongle, I don't get those screens on the VictronConnect app in the settings screen. I tried unplugging the CCGX so the Smart Dongle was in Primary position - but still no help.

What am I doing wrong or do I need to change?

Thanks

Unlike the MK3-USB interface, VE.Bus Smart Dongle only provides limited access (just to some functions).

But since you have a CCGX, you should be able to see/change all Multiplus settings via VRM and VEConfigure software. For details and requirements, check the manuals.

Unfortunately the demo library shows the options available via the MK3 Interface not the VE.Bus Smart dongle, but this is shown and explained in the manual of the smart dongle.

If the CCGX is online and connected to the VRM portal you could use the remote VE.config feature.

@Matthias Lange - DE Thanks for the proper path to find the settings. As I connected the VictronConnect through my MK3-usb I have the correct screens - all except there was no "Low Temp Cuttoff" field.

It should be just below the Absorption Time. Is the reason I don't have it because I don't have a temp sensor on my Multiplus? I have one on my SmartShunt and am using DVCC to pass temp, volts & current.

So does this mean my option is to get it programed is to use the " remote VE.config feature ".

Thanks for all the help!

Not sure because I never use VictronConnect because in almost every system we need assistents. I only use it for FW updates and setting up a 3 phase system because this is super easy with VictronConnect.


If you click on that option in the demo library it says that the temperature sensor is used for that so it is possible you don't get that option without the sensor connected.

Normally the battery/BMS should do that.

@Matthias Lange - DE 

Normally the battery/BMS should do that.

It works only w BMS with CAN bus connection.

When "2 signal BMS" assistant is used, MultiPlus gets confused when BMS sends "do not charge" signal when battery temp is below 5C.

MP assumes that battery is full and sets the SOC at 90%
