Male & Female MC4 Set

Contains a Set of Male and Female MC4 connectors.

An MC4 connector is the industry-standard, weatherproof electrical connector for solar panel installations, allowing easy connection of panels into strings by hand but requiring a tool for secure disconnection, with "MC" for manufacturer Multi-Contact (now Stäubli) and "4" for the 4mm contact pin diameter; these touch-proof connectors ensure safety and performance, preventing dangerous arcing common with improper setups. They're essential for reliable DC power transmission in solar systems, rated for high voltages (up to 1500V) and harsh outdoor conditions.
