30A or 40A controller?
I’m going to mount 2 160w panels rated at 9.5 isc amps to feed 2 6v batteries…260ah. If I were to mount a 3rd panel I’m still under 30amps so a 30 amp controller should work fine….or should it. I’ve ...

Hi Joel, What exactly did you buy? If it is MPPT I'd recommend 4 panels in series/parallel configuration. That is what has worked best for me.

Welcome to the "dark side" :B Im an owner who has spent "way" to much time in research on this subject. I would be glad to help. Would you like to know what panel voltages would work best for PWM?
I don't have the panels yet and am still in the "sponge" mode so will try to soak up any info you have to offer.
Did your research include much about panel diodes?
