It depends on a lot of different factors. For one 100w panel with a 3% acceptable loss You can have up to -85 feet with a Guage 8 wire -50 feet with Guage 10 wire -30 feet with Guage 12 wire We recommend you use our guage calculator www.renogy-store.com/category-s/1864.htmOur 100w panel runs at 18.9 volts and 5.29 Amps |

what kind of wire should i use bought a 100 watt set up for motor home do i use automotive wire also what size wire from charge controller to batteries panels to controller will be about 20 feet and from controller to batteries about 10 feet thanx I used 12 gauge wire for all the wiring from the controller to the batteries, since I don't ever expect to pull more than 20 Amps (the rating for 12 gauge). If you want to match the maximum specified current capacity of the controller, use 10 gauge wire (it handles 30 Amps). For the wires from the battery to whatever you plan to power, the heavier gauge the better. Again, I went for 12 gauge but if you're going to pull heavy loads, go for a lower gauge suitable for what you expect to draw, plus a safety margin. It doesn't matter where you get your wire (I got mine at Lowe's) as long as it's the proper gauge. |

Pete claas,
This also depends on what type of charge controller you will be using. 12 AWG is usually what we recommend our customers with our 100w panel. If you would like further assistance please contact our technical support department at 1(800)330-8678.
Thank you,
LP
