12 and 14 is pretty small wire compared to what I often see around here...just sayin'...
I ordered a kit with the wire length necessary and with it they provided #10 of the panel to the controller and the controller to the battery
. All fit exactly.
This way I can add two other panels without changing the wire.
I thought it was O.K. ..
I used 7 days last week on a site without service and everything worked well.
The price for this kit was a little bit lower, they had a special.
