New to this....I,ve read that the wire size is very important in DC apps. How would I go about connecting atleast #4 wire from this controler to the battery bank? The holes are so small '> '>
For whatever it is worth anytime I work with battery cable connections I use 4AWG cable where I can in my battery setup. I use BLUE SEA TERMINAL BLOCKS, FUSE BLOCKs, and SWITCHES so that every thing is designed to terminate into a RING TERMINAL LUG.
I only have one spot where the 4AWG cable slips into a ALLEN WRENCH lug which is at the PD9260C.
I use ANCOR Marine quality 4AW cabling and use the same company provided ring terminals which are hand crimped on the bulk 25-foot roll of 4AWG cable using a 8-ton Hand Crimper.
Having a cable marker kit from my working days I can add a nice heat shrink label to pretty things up with.
Any ring terminal I install also gets a good quality weather tight adhesive heat shrink sleeve.
