I have a system with a 200ah battery that I wish to monitor with a BMV-712. It is currently hooked up to a victron mppt solar charge controller as well as the battery of my van via a smart battery isolator that allows for charging when the car battery is above some certain voltage threshold.
I'm wondering if I need to do anything special to ensure that I'm monitoring the aux battery and not the "system" of both batteries which can read voltages of 14.4V while the aux battery has a voltage of <12V.
Thanks
