Question on solar controller hook up?
I finished up most of my solar install today and I noticed an issue when hooking up the solar controller to the batteries. I'm using an A/B Both switch to control what bank or banks I want to run....

OK, If the controller doesn't like a panel only connection what happens if the fuse to the battery blows?
That stopped the controller-battery pos wire from becoming the fuse and melting at the controller terminal, so the controller is toast anyway?
The OP is ok at 14.8v when connecting the 12/24 controller (no array connected yet) ISTR if it sees under 18v it will decide it is on a 12v battery and if over 18v it will decide it is on a 24v battery. so at 15v it will go 12v as desired.
