DC cable sizing calculator

The size of DC cabling you use with your solar panel array or wind turbine system is very important. If cable of too thin a diameter is used, this can lead to heating of the wire. At best, this can seriously impact efficiency through wasted energy and at worst, it can cause a fire and other damage to your system.

Our DC cable sizing tool will help ensure you select the right cable for your application. Please choose the voltage of your system, the number of amps and the length of cable required.
