I have to set up 4 bear fences that need to be powered by 12V batteries. To charge the batteries, I purchased several 50W solar panels and each has a voltage controller. The controller has terminals for the solar panel, the battery and the load.
My question is around what the fence charger should be connected to. Should I connect the fence charger to the battery directly or should I plug it into the load terminals? Or does it make a difference?
