Q/A

  • What are solar connectors?

    Solar connectors are electrical connectors used for connecting solar panels in a system. The MC stands for the manufacturer Multi-Contact. The 4 refers to the 4mm diameter of the contact pin. Modern solar modules use solar connectors because of their simplicity and ease in installation. In the past, modules were built with a junction box that required an installer to manually attach wires to the terminal posts. This is still sometimes used, but it’s becoming more of rarity. Solar connectors, which come in both male and female types, makes it easy to wire your solar array on your own.

Then, it’s just a matter of simply aligning the female connector with the male connector and securing. The Renogy solar connector assembly tool makes connections and disconnections quick and painless.
