Solar overvoltage protection - necessary?

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!

Will, I assume you are using a smart solar 100/50. If so, you just need to select the correct battery charging profile in the settings and the unit will take care of everything else.
