1 Is the shunt the sending info to a "brain" then bluetoothing to the little round read out on a Victron? How would I size the shunt? We only use 12v. No inverters. The only high draw item we have is the furnace. How close or far from the batteries is acceptable to install the shunt. Should it be very easily accessible? Meaning, is there a reason to view it regularly?

No, that's a hard wire. The bluetooth is to your phone. I'm sure the 500a version would be fine for almost any installation. Mine's close, but I have no reason to think it needs to be. No, but I choose to view mine on the smartphone almost every day to make sure the solar or shore charger is working.
