I have a few questions about the electric setup and hopefully someone can help. I’ve just installed a 280w solar system with a 12v 140ah deep cycle battery, inverter and charge controller.
I want to add a second battery and split charge from the starter battery as well.
My questions are:
1 . Do I need to wire the split charge through the charge controller or can it go straight to the battery? (Also I’m assuming both the solar system and split charge system need to be feeding the same battery)
- Does wiring the second battery in parallel require me to have a fuse or anything between the batteries or can it be a straight connection?
