Product Description
1500V 45A MC4 Connector for Solar PV Installations
The 1500V 45A MC4 Connector is a photovoltaic power connector designed for compatible 1500V DC solar installations. With a rated current of 45A, it provides a detachable connection for PV module cables, solar string wiring, combiner boxes and inverter circuits.
The connector features male and female mating components, crimp-type copper contacts and a snap-lock mechanism. Its insulated housing is designed for photovoltaic applications where outdoor exposure and secure electrical connections are important.
This 1500V 45A configuration gives solar equipment manufacturers and system integrators another current option within the SOLKV MC4 connector range.
Key Features of the 1500V 45A MC4 Connector
1. 1500V DC and 45A Electrical Rating
The 1500V 45A MC4 Connector is designed for photovoltaic cable connections with a rated voltage of 1500V DC and a rated current of 45A.
It provides a detachable electrical connection interface for compatible solar modules, photovoltaic strings, combiner boxes and inverter systems.
When selecting connectors for 1500V photovoltaic installations, engineers should consider the maximum system voltage, operating current, conductor size and installation conditions.
2. High-Strength Insulating Housing
The supplied MC4 connector series documentation identifies PPO/PA engineering plastics as housing materials for electrical insulation and mechanical support.
The insulated housing is intended to protect the internal connection components and support installation in outdoor photovoltaic environments.
Housing material and environmental performance should be verified against the actual 1500V 45A connector model before making model-specific claims.
3. Copper Contacts with Crimp Termination
The connector series uses copper conductive contacts with a crimp-type cable termination structure.
Crimp termination allows compatible photovoltaic cable conductors to be mechanically secured to electrical contacts using appropriate installation tools.
For a 45A connector configuration, correct conductor selection, contact sizing and crimp quality are important for maintaining connection performance.
4. Sealing Ring and Snap-Lock Connection
The MC4 connector series incorporates sealing components and a mechanical snap-lock connection arrangement.
These components are intended to help retain compatible male and female connector halves and protect the connection interface against environmental exposure.
The supplier’s general series documentation specifies IP67 protection. This rating should be confirmed for the exact 1500V 45A configuration before being presented as a certified model specification.
5. Secure Connection for Solar PV Systems
The connector’s plug-in mating structure supports photovoltaic cable installation and maintenance where compatible connector assemblies are used.
Its locking mechanism is intended to reduce unintended connector separation during normal operation.
Installers should verify connector compatibility and follow the manufacturer’s assembly requirements. PV connectors must not be disconnected under electrical load unless specifically rated for load-breaking operation.
