For a quick connect/disconnect between panels and controller, would MC4 or Anderson be better? I think Anderson SB-50 is a no-brainer from controller to battery.
The Renogy suitcase kit comes with SB-50 to alligator clips which I replaced with this:
10-gauge ring to SB-50My thoughts are to add a fuse to another set of these (minus ring terminals) from the controller mounted in basement, then MC4 from panels to a quick connect attached to the controller. I'll add branch connectors for combining another panel to the suitcase.
