Product Description
35A MC4 Connector for 1500V Solar PV Systems
The 35A MC4 Connector is a photovoltaic DC connector designed for compatible 1500V solar power systems. With a rated current of 35A, it provides a detachable cable connection for solar modules, PV strings, combiner boxes and inverter equipment.
The connector features male and female mating components, crimp-type contacts and a snap-lock connection structure. Its insulated housing supports use in appropriately designed outdoor photovoltaic installations.
The 1500V 35A configuration offers an additional current option within the SOLKV MC4 photovoltaic connector range, allowing installers and equipment manufacturers to select connectors according to system requirements.
Key Features of the 35A MC4 Connector
1. 1500V DC and 35A Electrical Rating
The 35A MC4 Connector is designed for photovoltaic cable connections with a rated voltage of 1500V DC and a rated current of 35A.
It provides an electrical connection interface for compatible solar modules, PV string wiring, combiner boxes and inverter equipment. Connector selection should consider the maximum system voltage, operating current, conductor dimensions and installation conditions.
2. High-Strength Insulating Housing
The supplied MC4 connector series uses PPO/PA engineering plastics for electrical insulation and mechanical support.
The housing helps separate internal conductive components from surrounding electrical equipment and is intended for outdoor photovoltaic installations.
Actual housing materials and environmental performance should be verified for the selected 1500V 35A configuration.
3. Copper Contacts with Crimp Termination
The MC4 connector series uses copper electrical contacts and crimp-type cable termination.
This connection method secures compatible photovoltaic conductors to contact terminals using appropriate crimping tools.
Proper conductor stripping, contact selection and crimping procedures help maintain dependable electrical contact. The actual contact plating and approved cable sizes should be checked for the 35A model.
4. Sealing Ring and Snap-Lock Connection
The connector series incorporates sealing components and a snap-lock mating mechanism intended to retain compatible male and female connector halves.
The supplied general MC4 specifications indicate IP67 protection. This rating should be verified for the exact 1500V 35A connector configuration.
Correct installation of cable seals, locking components and connector halves is essential for maintaining the intended protection performance.
5. Secure Connection for Solar PV Applications
The connector’s plug-in connection structure supports cable assembly and maintenance in suitable photovoltaic systems.
Its locking mechanism helps prevent unintended separation during normal operation, provided compatible connector halves are correctly assembled.
Only connectors with verified mechanical and electrical mating compatibility should be connected. Photovoltaic connectors must not be disconnected under load unless specifically rated for load-breaking operation.

FAQ
What is the rated current and voltage of this 35A MC4 Connector?
This version is specified for 35A and 1500V DC.
Is the connector suitable for outdoor photovoltaic applications?
The supplied MC4 series documentation lists IP67 protection. The exact connector configuration and assembly conditions must be verified.
What cable sizes are compatible with this connector?
The general series specifications list 4 mm² and 6 mm² photovoltaic cables. The specific contacts and cable size for the 35A version should be confirmed.
Can this connector be used with MC4 connectors from other manufacturers?
Only connector halves with verified mating compatibility should be connected. Similar appearance does not guarantee compatibility.
How does the 1500V 35A connector differ from the 1000V 35A version?
The primary distinction is their stated voltage rating. A 1500V-rated connector should be selected for PV installations requiring a verified 1500V DC connection.
