Waterproof Wire to Wire MC4 Solar PV Cable Connector for 4 sq mm and 6 sq mm wires

High-Quality MC4 Connectors Male-Female Pair with pins.

These connectors are suitable for crimping on to 4 sq mm and 6 sq mm cables.

MC4 connectors are single-contact electric connectors commonly used for connecting solar panels. MC4 stands for the manufacturer Multi-contact and a 4 sq mm contact assembly pin. MC4s allow strings of panels to be easily constructed by pushing the connectors from adjacent panels together by hand, but require a tool to disconnect them to ensure that they do not accidentally disconnect when the cables are pulled.

FAQs:

1. How to connect connectors?

The wire needs to be crimped at the ends provided for the purpose, and then it clicks into its place. Then the threaded back cover to be put on. This gives a weatherproof joint. The male to a female connector is a click on the type of simple assembly.

2. What is the current-carrying capacity or ampacity of these mc4 connectors?

30 AMPS

3. Is this suitable for 10 sq mm wire?

No. For 10 sq mm wire, you will need high capacity MC4. This is suitable for 4 and 6 sq mm wires.

4. What is MC4 and where it can be used?

MC4 stands for the manufacturer Multi-Contact and the 4 for the 4 mm diameter contact pin. Solar MC4 connectors are used for secure DC connection from solar panels to the inverter, charge controller, VFD, etc

5. Are these connectors waterproof?

Yes, it has IP67 which means waterproof, Weather resistant. Also, it is UV protected.
