What type of connector is a MC4?

MC4 connectors are a type of electrical connector commonly used in photovoltaic (PV) solar power systems. They are named after the Multi-Contact company, which developed this specific connector system.

Key features of MC4 connectors include:

Compatibility: MC4 connectors are standard connectors used in solar installations and are designed to be compatible with most photovoltaic panels and inverters.

Weather Resistance: They are designed to be weather-resistant and can withstand exposure to sunlight, rain, and other environmental elements.

Ease of Use: MC4 connectors are known for their ease of use, featuring a snap-lock mechanism that simplifies the process of connecting and disconnecting solar panels.

Safety: These connectors are designed to meet safety standards for solar power systems and are often used in conjunction with cables and wiring specifically designed for photovoltaic applications.

Waterproof Sealing: MC4 connectors typically have a waterproof sealing mechanism, ensuring that the connections remain secure and protected against moisture.

Rated Voltage and Current: MC4 connectors are designed to handle specific voltage and current levels commonly found in solar power systems. They are available in various configurations to accommodate different electrical requirements.

Standardization: MC4 connectors have become a standard in the solar industry, making them widely adopted and interchangeable among various solar equipment manufacturers.

These connectors are gendered, with male and female versions. Typically, solar panels come with male MC4 connectors on one end and female connectors on the other, allowing for easy daisy-chaining of panels in an array.

When working with solar installations, it's important to use connectors and cables that are compatible with the specific requirements of the system and adhere to industry standards to ensure safety and proper functionality.
