Post subject:  Wire Sizing, Guage for Turbine Charge Controller to Battery

Off of the charge controller and the battery bank what is the wire sizing that is needed for them to hook up.
Regular battery cable or size 8 AWG or "8 Guage" like the rest of the system. etc. curious

Post subject:  Wire Sizing From Controller to Battery

Sorry I have not already replied to this. I am too busy this weekend to do it justice and provide a FULL answer. I will make a very brief reply that ( IT DEPENDS ). It depends on factors of amps of current, volts of current, and distance of the connection. Add to that, there is a reason that I wire with heavier guage usually than what would be required.

Acceptable guidelines usually go with a wiring that allows 5% of the power to be lost to resistance. Five percent is normally acceptable in low voltage systems, but I like to wire for a 2% figure and I divide the normal distances that a wire would carry, beefing it up. Usually that is divided by 2 to 2.5. Of course, I will think of cost also. Example, on my battery bank, I use beefy welding cable at 1 or 2 guage. I could use less beefy, save money, but over time my system does better efficiency with the heavy cable.

The wiring I use from controller to battery bank is always stranded and I use from 6 to 8 guage depending on what size turbine and how much solar, the length etc. Most people are using 8 guage there.
