Description
MC4 Connector Pairs are specialized electrical connectors primarily used in solar photovoltaic (PV) systems for connecting solar panels. Here’s an overview based on the available information:
Key Features:
-
Design: MC4 connectors come in pairs, with one male and one female connector. The male connector has a metal pin, and the female has a metal socket, forming a tight electrical connection when joined.
-
Material: The connectors are housed in durable, UV-resistant, and flame-retardant plastic (like PPO or PA) for outdoor durability.
-
Locking Mechanism: They include a built-in locking mechanism (often a snap-in lock) to prevent accidental disconnection. Disconnecting usually requires a specific tool or technique.
-
Voltage and Current Ratings:
-
Modern MC4 connectors are rated for up to 1500 V DC (UL and IEC certified) with current ratings that can go up to 95 A with 6AWG PV cable, or 70 A with 10mm² PV cable for the MC4-Evo 2.
-
-
Compatibility:
-
Designed for use with PV cables of various insulation diameters. It’s crucial to use connectors and cables from the same manufacturer to ensure proper mating and safety (as per NEC and IEC standards).
-
They are generally compatible with solar cables of 2.5mm² to 6mm² (AWG14 to AWG10).
-
-
Weather Resistance: They have an IP67 waterproof rating, making them suitable for harsh outdoor environments.
