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

Hi,

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,

Ralph

If you are using lithium batteries and have a VE.Bus BMS in the system, the Cerbo cannot control the Multi. Thus, the DMC is essential for remote control of the Multi. If you have lead batteries or some variant of lead (AGM, SLA, Gel, etc.) then the Cerbo can remotely control the multi through the VE.Bus protocol.

I am using AGM batteries. Does this mean that the Cerbo can do everything that the DMC can and the DCM would not be needed?

I'm somewhat regretting my purchase of the MultiControl for my Lithium system. It's great to have while onboard, but it prevents me from remote controlling the system while the boat is sitting at idle at the dock. I wish that Victron would put out a firmware update that would allow you to override the DMC from the Cerbo.
