I thought I could go right to a chart for the capacity of amps on wire size. I cannot find the chart I used before. I have a 24 v system and need to go either 420 ft or 375 ft from the solar panels to the control room. 5 panels 240 w 24v. ea panel is fused at 10 amps. 2 wires from the combiner box to controler. Could some one direct me to a chart. 13
