These MC4 solar connectors are color coated single connector leads. White MC4 cable extensions come with a single MC4 Female connector for your negative wire lead, and Black extension wires come with a single MC4 Male connector for your positive wire lead. You can contact us with any questions you have about our solar MC4 connectors.Will MC4 connectors work with older MC3 type connectors?
MC4 will not connect with older MC3 type connectors. The MC4 connectors work best with 4mm and 6mm solar cable. When you buy any new solar panel (usually over 30 Watts) it will be already fitted with two 500 - 900mm leads with MC4 connectors attached for you to get the power safely out of the solar panel.What is an MC4 extension cable?
Just like an extension cord has a male plug on one end and a female plug on the other, an MC4 extension cable has a male connector on one end and a female connector on the opposite end. They are available in many different lengths from 8 feet to 100 feet long. Let's go back to our first example of wiring two modules in series.How do I Disconnect my MC4 cables?
If for some reason you need to disconnect your MC4 cables, you will need one of these. You must insert the two extended posts on the end of the tool into the side of the female MC4 connector. This disengages the locking mechanism on the male connector and allows the two connectors to separate.
