Solar MC4 Connector - Secure & Reliable Solar Cable Connections
Solar MC4 Connector
An MC4 (Multi-Contact 4mm) connector is a standardized single-contact electrical connector used globally in solar photovoltaic (PV) systems to connect solar cables, especially for DC connections between solar panels. Designed for quick, waterproof, and safe plug-and-play connections, MC4 connectors ensure secure, low-resistance electrical continuity with long-term reliability.
Key Components of an MC4 Connector:
- Male & Female Ends – Lock together securely to form a weatherproof seal
- Tinned Copper Contacts – Provide high conductivity and corrosion resistance
- Insulated Housing (PC/PA) – UV-resistant and flame-retardant
- Locking Clips – Prevent accidental disconnection
- Crimp Terminal – Ensures tight connection to the cable conductor
Key Features & Advantages:
- Quick Installation – Push-fit design makes connections fast and tool-friendly
- Weatherproof (IP67/IP68 Rated) – Ideal for outdoor use in any climate
- UV & Flame Resistant – Built to withstand harsh solar farm conditions
- Low Contact Resistance – Ensures efficient power flow
- High Current & Voltage Handling – Supports up to 1500V DC and 30A
- Locking Mechanism – Ensures tamper-proof and secure cable joins.
