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?
