Product Description
1000V MC4 Connector with 45A Current Rating
The 1000V MC4 Connector is a photovoltaic DC cable connector designed for electrical connections in solar power systems. With a rated voltage of 1000V DC and a rated current of 45A, it provides a connection option for compatible photovoltaic modules, solar strings, combiner boxes, and inverter equipment.
The connector incorporates male and female mating components, crimp-style electrical contacts, and a snap-lock connection mechanism. Its insulated housing is designed to support outdoor photovoltaic applications while providing mechanical protection around the conductive components.
The 45A version is an alternative to lower-current connectors for appropriately designed PV circuits.
Key Features of the 1000V MC4 Connector
1. 1000V DC and 45A Electrical Rating
The 1000V MC4 Connector is designed for photovoltaic cable connections with a rated voltage of 1000V DC and a rated current of 45A.
It provides a detachable electrical interface for compatible solar modules, PV strings, combiner boxes and inverter equipment. Connector selection should consider operating current, conductor dimensions, ambient temperature and installation requirements.
2. High-Strength Insulating Housing
The MC4 connector series uses PPO/PA engineering plastics to provide electrical insulation and mechanical support for its internal connection components.
The housing is designed for outdoor photovoltaic applications where exposure to heat, moisture and environmental conditions must be considered.
Its protective structure helps separate the conductive contacts from surrounding equipment components.
3. Copper Contacts with Crimp Termination
The connector features copper contact components designed for crimp-type cable termination.
This connection method allows compatible photovoltaic conductors to be secured inside the terminal contacts using suitable crimping tools and procedures.
Correct cable preparation and contact selection help maintain electrical connection quality and reduce the risk of poor contact caused by improper installation.
4. Sealing Ring and Snap-Lock Connection
The connector incorporates a sealing arrangement and mechanical snap-lock structure for compatible male and female connector assemblies.
The sealing components are designed to help protect the internal electrical contacts from dust and moisture.
The supplier’s general MC4 series documentation specifies IP67 protection. Proper assembly, connector mating and cable sealing are necessary for maintaining the intended protection level.
5. Secure Connection and Installation
The connector’s locking mechanism helps retain compatible connector halves and reduce unintended separation during normal photovoltaic system operation.
Its plug-in structure supports convenient connection during solar equipment installation and maintenance.
Only verified mating-compatible connector models should be connected, and photovoltaic connectors should not be disconnected under electrical load unless specifically rated for that operation.

FAQ
What are the electrical ratings of the 1000V MC4 Connector?
This version is specified for 1000V DC and 45A.
Is this photovoltaic connector suitable for outdoor installation?
The supplier's MC4 series specifications list an IP67 protection rating. The intended protection performance depends on correct assembly and suitable installation conditions.
Which PV cables are compatible with the 45A connector?
The general series documentation lists 4 mm² and 6 mm² cables. The specific contact and cable combination should be confirmed for the 45A configuration.
Can this connector be mated with MC4 connectors from other suppliers?
Only connector models with verified mating compatibility should be connected. Similar connector appearance does not guarantee compatibility.
Can a 1000V MC4 connector be installed in a 1500V photovoltaic system?
No. A connector rated and verified for 1500V DC should be selected for a system operating above the 1000V DC rating.
