Is it possible to connect a single GX Touch to a cerbo GX and a multiplus GX. The Cerbo will be connected to a 12v Bank with a REC BMS and the Multiplus to a 48v Bank with REC BMS.

Hi @luckybeanz
There is no way to connect the GX touch display to the MultiPlus-II GX.
It is an accessory that is only compatible with the Cerbo GX.
Okay, but if the GX touch is connected to the cerbo. The 12v battery to the cerbo and the 48v to the GX, what happens when the cerbo and the GX are connected together? Can the GX touch display information for both batteries?
There is no way to connect two GX devices together.
Do you have a system wiring diagram?
Thanks for the reply and sorry for my delay, I am trying to wrap my head around this all. You say there is no way to connect two GX devices, but what happens if one connects them via a VE.Bus port?
Here is a diagram, basically what I am trying to achieve is having both the 48v and the 12v data displayed on a single screen.
Connecting the VE.Bus cable from a MultiPlus-II GX (with it's internal GX card also still connected) to a Cerbo GX will do nothing (at best). It is not a supported configuration.
That VE.Bus cable connection on the MultiPlus-II GX is intended to connect to another MultiPlus-II Inverter Charger for Parallel or 3 phase configuration options.
Given the complexity of your setup, I would strongly consider consulting with a local distributor, who is willing to support you all the way.
It might be possible to get a reasonable interface for the two battery banks (12V and 48V) using a marine MFD, which is designed to show multiple BMVs.
BUT PLEASE TALK TO A MARINE SPECIALIST, I am not one, and this info should just be treated as potential options to consider and investigate, and not advice from Victron.
Additional resources still need to be added for this topic
