How to plus MC4 to Solar cable
How to plus MC4 connector to solar cable
Attention: There are multiple types of interlocking PV connectors. This article addresses MC4 connectors(EVO2), but the same principles apply to other connectors such as Amphenol H4, Tyco, and SMK.
What is an MC4 connector (male connector & female connector) and an MC4 extension cable (8ft, 15ft, 30ft, 50ft, 100ft)?
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 or TUV 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.
Apply tool:
PV cable strip tool
PV cable crimping tool
MC4 wrench
Step
1. Strip the wire
Firstly Chosee the right wire gauge
Length should be 3~5mm
Step2
Crimp the wire
Firstly chosse the right wire gauge hole.
Put the pin in the hole, open side up.
Insert stripped cable end until insulation comes uo against crimp insert.
Step 3
Insett crimped-on contact into insulator and pull gentlu on lead.
Black cable insert male connector(-), red cable insert female connector(+)
Step4
Tighten the nut.
