Description
35A MC4 Connector for 1000V Solar PV Systems
The 35A MC4 Connector is a photovoltaic cable connector designed for use in compatible 1000V DC solar power systems. With a rated current of 35A, it provides a detachable connection solution for solar panel wiring, PV string circuits, combiner boxes, and inverter equipment.
The connector features male and female mating components, crimp-type electrical contacts, and a snap-lock connection mechanism. Its insulating housing is designed to support electrical connections in outdoor photovoltaic installations.
The 1000V 35A configuration offers an additional current option within the SOLKV photovoltaic connector range, allowing equipment manufacturers and solar installers to select products according to their system requirements.
Key Features of the 35A MC4 Connector
1. 1000V DC and 35A Electrical Rating
The 35A MC4 Connector is designed for photovoltaic cable connections requiring a 1000V DC voltage rating and 35A current capacity. It provides a detachable connection interface for compatible solar modules, PV strings, combiner boxes and inverter systems.
The connector should be selected according to the operating current, cable dimensions and electrical requirements of the installation.
2. High-Strength Insulating Housing
The MC4 connector series uses PPO/PA engineering plastics to provide electrical insulation and mechanical support for the internal contact assembly.
The housing is intended for outdoor photovoltaic installations where resistance to heat, mechanical wear and environmental exposure is important.
3. Copper Contacts with Crimp Termination
The 35A MC4 Connector uses conductive copper contacts with a crimp-type cable termination structure.
Crimping provides a mechanical and electrical connection between compatible photovoltaic conductors and connector contacts. Correct cable preparation and suitable crimping tools help maintain connection quality.
4. Sealing Ring and Snap-Lock Connection
The connector incorporates a sealing structure and snap-lock mating mechanism designed to retain compatible male and female connector halves.
The supplied MC4 series specifications indicate IP67 protection. Correct connector assembly, cable sealing and mating are necessary to achieve the intended protection performance.
5. Secure Connector Assembly
The connector’s locking structure helps reduce unintended separation during normal photovoltaic equipment operation.
Its plug-in mating arrangement supports installation and maintenance of compatible PV cable assemblies. Mechanical and electrical compatibility must be confirmed before mating different connector models.
