MC4 connectors are the electrical devices used to connect solar panels through a single contact. They tie up the connections of a solar system by joining several solar panels or several groups of solar panels together. 

Here MC refers to Multi-Contact and 4 indicates the dimension of diameter pin in mm. The high-quality tool with a sealed tip and metal pin is a great way to establish electrical contact between the modules.

The designation of the connector consists of a plug and a socket that are plastic shells from inside. The plug is a male connector with a cylindrical shape while the socket is electrically female having a square body. The plastic fingers of the female socket are pressed to insert into the plug. Popping outwards, the two components get locked together to serve the purpose.

Solar MC4 connectors and branch connectors are available in several types. So it’s worth spending 10 minutes reading the complete information about all these solar MC4 connectors for choosing the best that meets all your needs.

Tools Required With MC4 Connectors

Using the MC4 solar connectors in a solar system is a very simple process. All you’ll need are a few tools to crimp the connectors. 

The two main gadgets required to connect the MC4 connectors to the solar panels are-

  • MC4 Crimping Tool
  • MC4 Spanner

#1. MC4 Crimping Tool

An MC4 crimping tool, also known as, a crimper and crimping pliers, is used to deform and join the ends of the wire and the connector.

The grip obtained creates a solid contact between the two ends. With strain relief, the tool makes a superior connection mechanically while avoiding solder wicking.

#2. MC4 Spanner/Wrench

The MC4 spanner or MC4 wrench is a tool used to screw and unscrew the connector. The lightweight gadget can save your time and power for installing the connectors. 

An MC4 spanner is an efficiently working device you’ll need to assemble and disassemble the MC4 connectors.

#10. How to Use MC4 Connectors

MC4 connector can be used to connect multiple solar modules in series as well as in parallel. Both the combinations require different input and hence provide distinctive outcomes.

In simple words, you can use an MC4 connector to wire the solar modules in either of the two combinations according to your need. 

MC4 Connectors Wiring in Series:

Connecting solar panels in a series combination is the easiest of all wirings. To use this arrangement, you’ll need to connect the positive lead of the panel to the negative lead.

In simple words. Snapping the male connector into the female one can do your work.


When you connect two or more solar panels in series, the resulting voltage is the sum of the individual voltages while the current remains constant. 

MC4 Connectors Wiring in Parallel:

The parallel combination is the most preferred wiring of solar panels used to generate optimum benefits. Here, the positive leads are connected, the same is the case with the negative leads.

Since the arrangement is not possible naturally, you’ll need an MC4 multi-branch connector to achieve the purpose.


When connected parallelly, the solar panels generate an optimum current that is the sum of the individual current quantity. Whereas, the voltage of the solar system remains the same.

Frequently Asked Question

An MC4 connector is a device that connects the adjacent solar panels using a single contact.

Yes, one of the biggest advantages of using an MC4 connector is that it is waterproof.

Yes, MC4 connectors are universal in the solar industry.

Yes, for establishing a flawless connection to operate your solar system at its highest efficiency, you’ll need a solar MC4 connector.

MC4 solar connectors are easy to use devices that can be unlocked just by the simple press and pull out. You can use MC4 spanner for the same.

To crimp an MC4 connector, you’ll need wire cutters, wire sippers, a crimping tool and a connector tool.

A plier with a flat head can work similarly.

Crimping is possible with regular pliers but the quality degrades when compared to the MC4 crimping tool.

Generally, the female connector of an MC4 device is linked with a positive lead though checking the terminals is always recommended.

You can use the MC4 branch connectors to wire the solar panels making a parallel combination.

You’ll need an MC4 crimping tool to crimp the MC4 connectors.

Yes, you can connect several solar panels using MC4 solar connectors.

Solar panels can be connected in any of the two sequences, however, parallel connection is most preferred for it increases the current being generated.

Though MC4 connectors are not necessary, they are extremely effective to increase the overall productivity of your solar system.
