MC4 Connectors How to Make Solar Panel Cables DIY
What is an MC4 connector (male connector & female connector) and an MC4 extension cable?
If you're asking this question, you've probably noticed that most modern high power solar modules are manufactured with wire leads that have MC4 connectors on the ends. Years ago, solar modules were built with a junction box on the back that required the installer to manually attach wires to the positive and negative terminal posts. This method is still used, but it's slowly becoming a thing of the past. Modern solar modules tend to use the MC4 connectors because they make wiring your solar array much simpler and faster. The connectors come in both male and female types which are designed to snap together. They meet the requirements of the National Electric Code, they're UL certified and the preferred connection method of electrical inspectors. Due to the locking mechanism of the MC4 connectors, they will not come unplugged and are well suited for outdoor environments. The connectors can be separated but it requires a special MC4 unlocking tool.
