I have a unique set up that contains 2 battery systems. I have a 24 volt system with a victron 100/50 charge controller for the inverter. I also have a victron 100/30 charge controller for the 12 volt items inside the self build RV. I have both of them connected to a victron venus gx. I am only showing the 12 volt side of the system and nothing about the 24 volt side. How can I get it to show both battery banks without the communication error?
