Contains (2) 20' wires pre-assembled with a male and female MC4 connector on one end of each; the other end is blunt. This type of connector system is easy to install and uses “snap-in” type of safety locking clips to lock the two mating connectors, thereby, avoiding unintentional disconnection. Also, the mating contacts are sealed against ingress of dust and water. These wires are used to connect the output of the solar panel to the various components of a solar installation.
