Any insight appreciated. Thanks.
The connector in the front goes directly to the battery. You can run a second controller (I do). It will feed the batteries fine when controllers are on bulk mode, but you may get one controller shutting down or going into a trickle as the other panels finish up charging. It will not hurt your batteries.
It does work though and is better than not having the portable panel.
