OP states he has two 6V Crown batteries @260 AH. The length of the run from modules to controller is 16'. He does not say what length of run is from the controller to batteries.
If it was me, I'd use #10 MCA cable from the modules to a combiner box on the roof and then run AWG 4 from the box to the controller (interrupting it with a circuit breaker mounted close to the controller). For the controller to batteries, I'd use the same AWG 4, depending on the length of run to the batteries. I tend to use larger wire than most but I reasoning is that I'd rather pay a few dollars more for wire, initially, than give up solar harvest eternally.
