Working Temperature: -40°c~+90°c; the maximum Detailed Product Description NYAF 1.5sq mm Electrical Cable Wire , Flexible Copper PVC Insulation Wire Applications Used in the switch control, relay and instrumentation panels of Before purchasing a dc wire, you must ensure that you consider features and specifications such as the inverter technology, type, capacity, max. wattages of solar panel support, load capacity, Oct 02, 2022 · Let’s do the math: 12-volt, 100W solar panel, and 18V Vmp To solve, you’ll divide 100-watts by 18-volts = 5.5 amps. Presuming that you merely require 100W of power, you can utilize a 14 AWG solar wire. We arrived at this conclusion because the capacity of a 14 AWG wire with a 2 percent drop in volts is 15 amps.
