Product Description
1500V 50A MC4 Connector for Solar Power Systems
The 1500V 50A MC4 Connector is a photovoltaic DC cable connector designed for compatible solar power systems requiring a 1500V voltage rating and 50A current capacity. It provides a detachable electrical connection for photovoltaic modules, DC string wiring, combiner boxes, and solar inverter equipment.
The connector features male and female mating components, crimp-type copper contacts, and a mechanical snap-lock connection. Its insulated housing supports cable connections in outdoor photovoltaic environments when correctly installed.
The 50A configuration provides an additional current rating within the SOLKV MC4 photovoltaic connector range, supporting selection for solar equipment with suitable electrical and cable requirements.
Key Features of the 1500V 50A MC4 Connector
1. 1500V DC and 50A Electrical Rating
The 1500V 50A MC4 Connector is designed for photovoltaic cable connections with a rated voltage of 1500V DC and a rated current of 50A.
It provides a detachable connection interface for compatible photovoltaic modules, solar string circuits, combiner boxes and inverter equipment.
Connector selection should consider maximum DC system voltage, operating current, cable conductor size, ambient temperature and applicable installation requirements.
2. Insulated Connector Housing
The supplied MC4 connector series documentation identifies PPO/PA engineering plastics as materials used for electrical insulation and mechanical support.
The housing provides insulation around the conductive contacts and is intended for photovoltaic cable connections in outdoor operating environments.
The exact housing composition and environmental performance should be checked against the selected 1500V 50A connector model.
3. Copper Contacts with Crimp Termination
The MC4 connector series uses copper conductive contacts and crimp-type cable termination.
This termination method allows compatible photovoltaic conductors to be secured to the electrical contacts using suitable crimping tools.
For a 50A connector configuration, correct cable size, contact selection and crimping quality are important. Installers should follow the approved conductor and contact specifications for the selected model.
4. Sealing Structure and Snap-Lock Connection
The connector series incorporates a sealing arrangement and mechanical locking mechanism intended to protect the connection interface and retain compatible connector halves.
The supplier’s general MC4 series documentation indicates IP67 protection. This rating should be confirmed for the exact 1500V 50A configuration before being treated as a model-specific specification.
Proper cable sealing, connector assembly and mating are necessary to maintain the intended environmental protection.
5. Connection Design for Solar PV Systems
The connector’s plug-in mating structure supports photovoltaic cable assembly where compatible male and female connectors are used.
Its mechanical locking arrangement helps reduce unintended separation during normal operation.
Only electrically and mechanically compatible connector halves should be mated. PV connectors must not be disconnected under load unless specifically designed and rated for that operation.

FAQ
What is the rated voltage and current of this 1500V 50A MC4 Connector?
This version is specified for 1500V DC and 50A.
Is the connector suitable for outdoor photovoltaic applications?
The manufacturer's general MC4 series specifications list IP67 protection. The exact 50A configuration and installation requirements should be verified.
What cable sizes are compatible with the 50A connector?
The supplier's series documentation lists 4 mm² and 6 mm² PV cables. Contact selection and cable compatibility for the 50A current rating should be confirmed before installation.
Can this connector be mated with MC4 connectors from other manufacturers?
Only connector halves with verified mechanical and electrical mating compatibility should be connected. Similar appearance does not guarantee compatibility.
How does this product differ from the 1000V 50A MC4 connector?
The primary difference is the specified voltage rating. The 1500V version is intended for systems requiring a verified 1500V DC connector, while the 1000V version is limited to its stated voltage rating.
