MC4 Connector - Male and Female Set

MC4 (Multi-Contact 4mm) connectors are widely used in photovoltaic systems to connect solar modules to cables. There are two main types of MC4 connectors: male and female , which fit together to ensure a safe and efficient connection, suitable for withstanding demanding environmental conditions. Each type of connector performs a specific function within the system, enabling the efficient and safe transmission of power.

MC4 Male Connector:

• Function : The MC4 male connector is the part of the connector that contains the metal pin and fits into the female part of the system. Its function is to ensure the transmission of electrical current when it comes into contact with the female connector.
• Features :
  • Metal pin : The male connector has a metal pin that connects to the female part, creating the electrical connection.
  • Insulation and sealing : The connector is coated with an insulating material and sealed, ensuring that the connection is protected against water, dust and other adverse environmental conditions.
  • Durability : Designed to withstand harsh outdoor conditions including exposure to solar radiation, rain and extreme temperatures.
  • Ease of installation : The connector is designed to be easily connected and disconnected, without the need for specialized tools, but requiring a secure snap force to ensure a flawless connection.

MC4 Female Connector:

• Function : The female MC4 connector is the part that receives the metal pin from the male connector, completing the electrical connection.
• Features :
  • Pin cavity : The female connector has a tube-shaped cavity where the metal pin of the male connector fits, establishing the electrical connection.
  • Sealing : Like the male connector, the female connector is also sealed to protect the connection against water, dust and corrosion.
  • Resistance : The female connector is robust and reliable, ensuring a long-lasting connection without failures over time.
  • Simple Installation : It is equally designed to be easy to install and disconnect, providing flexibility and security in system configuration.

Common Features:

• Protection rating : Both male and female connectors are IP67 rated, meaning they are dustproof and can be submerged in water up to a certain depth, ensuring high resistance and durability in outdoor environments.
• Compatibility : MC4 connectors are compatible with solar cables from 4mm² to 10mm² and can be used in photovoltaic systems of any type, from residential to commercial.
• Secure connection : These connectors ensure a firm and watertight connection, minimizing the risk of electrical faults, short circuits or loss of efficiency due to poorly made connections.

Advantages:

• Easy installation and disconnection : No specialized tools are required for installation or removal, making it easy to assemble and maintain the system.
• Reliability : MC4 connectors ensure a stable and efficient connection, essential for the good performance of the photovoltaic system.
• Weather Resistance : Designed to withstand extreme temperatures, UV exposure and other environmental conditions, making them ideal for outdoor applications.

MC4 connectors are essential to ensure safety and efficiency in solar installations, providing a stable and long-lasting connection between the solar modules and the inverter.
