Hi,
I’m installing solar to charge an existing 12v lead acid battery system, I’ve got 2 panels, a 100/50 smart solar mppt controller and I’m also going to install a smart shunt or BMV 712 smart to monitor the battery state of charge etc... ( the current system doesn’t have any battery monitoring in place)
My question is do I need to be concerned about protecting the batteries from an overvoltage event from the solar charging, or will the charge controller provide protection? I was considering using the ve direct non inverting on/off cable between the shunt/BMV and the charge controller?
Thanks in advance!
