You'll need to use the sizing calculator to size each wire length as follows: Solar to Regulator Wire. For this length voltage drop is not critical as the regulator can deal with voltage variations, however the power loss should be kept to less than ~3-5%. Battery to Regulator Wir To avoid excessive voltage drop, select a size wire that will minimize voltage drop. You need to know the length of the wire run and the load (current) that will be on the circuit. To determine the load, add up the wattage of all electrical devices that will be on the circuit and divide this total by the voltage of the circuit, usually 120.
