I would go with with minimum 8 AWG for the run from the controller to the batteries.
Six foot run at 13 volts / 20 amps.
Loss with 12 AWG = 0.38 volts (way too much voltage drop)
Loss with 8 AWG = 0.15 volts (still a bit high)
I appreciate the info. I was thinking 6awg from the controller to the batteries. However the run from the batteries to the 3k inverter is another story. The inverter came with 0AWG wire but, it's only 15" which is about 4' short. What I was thinking was to use the provided 15" 0AWG wire to a 400A waterproof breaker mounted to the tongue of the trailer, then continue to the inverter with more 0AWG wire.
Final piece of the puzzle what size breaker should be used between the panel and the controller. I haven't settled on which controller but, I do know it will be 35A or 40A based on what's needed.(335w panel to 2x 6v battery bank) The reason for a breaker is to give me a simple way to disconnect the panel if any work needs to be done. It's not something I intend to use regularly.Thoughts and or suggestions?
