My marine electrical includes an Automatic Smart Battery Switch and was wondering how to install a trickle solar charger to it.
Should I bypass the switch, or should it be installed just like a Guest battery charger to the “house” battery? If so, do I still need a charge controller, and where should it be located (between battery and panel, or battery and smart battery switch)?
Thanks for all of your help.
Connect the positive lead of the charger to the battery switch stud with red cable from your house battery and connect the negative lead of the charger to the ground bus. Connecting the charger to the switch will help reduce the amount of clutter on the battery.
If you want the solar charger to charge the starting battery also, turn the switch to either ON (VSR will control the charge) or COMBINE (batteries are mechanically paralleled with the switch).
Hope this helps,
