I am just setting up a system in a self-build camper/RV. I have a Multiplus (12/2000/80) with DMC, Smartsolar 100/20 and BMV-712, all of which I want to connect to the Cerbo GX. I hadn't planned on the Cerbo GX initially, but the dealer told me about it when I was buying the other kit so I added it in without much research. When I started to research it came to light that I no longer needed the DMC for the Multi plus, and in fact if you connect it in you lose the option of setting current limits or switching the MP to 'Charger Only' mode via the Cerbo screen. I also thought that I didnt need the BMV-712 screen and that I could just conncet the shunt directly into the Cerbo GX, however it seems the shunt has an RJ12 connection and it is looking like I will have to wire the shunt to the BMV-712 screen and then back with a VE.direct cable to the Cerbo GX - is this correct? It seems a little silly to be wiring in the BMV screen when all the information will be on the Cerbo GX screen.
