MC4 Solar Connector Pair – Male & Female 4-6mm

What Are MC4 Connectors?

MC4 connectors (Multi-Contact 4mm contact pin) are the globally accepted standard for DC solar cable connections. Each pair includes one male and one female locking connector, compatible with 4mm to 6mm cross-section PV cable.

The push-lock mechanism creates a secure, weatherproof connection that cannot be accidentally disconnected — an important safety feature when working with live solar DC wiring.

Specifications

• Compatible cable cross-section: 4mm to 6mm
• Rated voltage: 1000V DC
• Rated current: 30A continuous
• Ingress protection: IP67 (dustproof and water submersion rated)
• Housing: UV-stabilised polycarbonate
• Contacts: Tinned copper with silver-plated contact surfaces
• Standard: IEC 62852, TUV certified

Applications

MC4 connectors are used to join solar panels in series or parallel strings, and to connect panel strings to the inverter or charge controller input. They are compatible with all major solar panel brands including Jinko, Longi, Seraphim, Canadian Solar, and virtually all panels sold in South Africa.

Installation Note

Always use a dedicated MC4 disconnection tool to separate these connectors. Attempting to pull them apart by hand risks damaging the locking collar and creating an unreliable connection. These connectors should only be mated and unmated when the circuit is de-energised or when rated MC4 tools and personal protective equipment are used.
