Additional portable panel
I have 4 100 watt panels on top of my trailer, Rover 40 amp controller and two wet deep cycles. Because I'm not always in full sun, I also have a 100 watt portable panel with it's own controller to chase the sun with. My question is: What is the best way to connect the portable into my existing system? Can I just add the output of the controller of the portable system directly to the batteries and have have the output of both controllers connected to the batteries?
