You don't need a fuse on the PV to controller line but it is handy to have some sort of switch for disconnecting that line before you disconnect the controller-battery line for any reason. Some guys use a fuse there so they can just pull it as their on/off switch.
Excellent point. I "know a guy" that had energized panels connected to the controller when there was no battery connection. This caused a malfunction within his controller whereby it would show 100W+ output in pitch black. There's a thread on that somewhere. :)
