1000V MC4 Connector for Solar PV Systems
The 1000V MC4 Connector is a 30A photovoltaic DC connector designed for connecting solar panels, PV cables, combiner boxes, and inverter systems. It provides a secure electrical connection for compatible 1000V DC solar power installations.
Featuring male and female connector components, the product combines crimp-type copper contacts with a snap-lock mating mechanism. Its PPO/PA insulating housing and IP67 protection design make it suitable for outdoor photovoltaic applications when properly assembled.
The connector supports 4 mm² and 6 mm² solar cables, providing a practical connection option for residential, commercial, and industrial PV systems.
Key Features of the 1000V MC4 Connector
1. 1000V DC and 30A Electrical Rating
The 1000V MC4 Connector is designed for photovoltaic DC connections with a rated current of 30A. It provides a connection interface for compatible solar modules, PV strings, combiner boxes and inverter equipment.
2. High-Strength Insulating Housing
The connector series uses PPO/PA engineering plastics to provide electrical insulation and mechanical support. The housing is designed for outdoor photovoltaic applications, with material properties intended to support resistance to heat, environmental aging and mechanical wear.
3. Copper Contacts with Crimp Termination
Copper contact components provide the electrical connection between compatible photovoltaic cables. Crimp termination helps secure the conductor within the contact when suitable tools and installation procedures are used.
The supplied series specifications indicate contact resistance of ≤0.5 mΩ, supporting low-resistance electrical connections when correctly assembled.
4. Sealing Ring and Snap-Lock Connection
The connector incorporates a sealing structure and a mechanical snap-lock mechanism. The locking components help retain compatible male and female connector halves, while the sealing arrangement is intended to protect the electrical connection against dust and moisture.
The supplied MC4 series specifies IP67 protection. Correct mating, cable sealing and assembly are essential for maintaining the intended protection level.
5. Secure Connector Assembly
The connector features a locking arrangement designed to help prevent unintentional separation during normal operation.
Its crimp-type contacts and plug-in mating structure support installation and maintenance of compatible photovoltaic cable assemblies. Only verified mating-compatible connectors should be used together.
