Solar Cable Compatibility
CN4U-P supports commonly used photovoltaic cable sizes of 2.5 mm², 4.0 mm² and 6.0 mm², corresponding to approximately 14 AWG, 12 AWG and 10 AWG.
The appropriate cable size should be selected according to the PV system current, installation conditions, cable specifications and applicable electrical requirements.
Before installation, ensure that the cable, connector, crimping method and mating connector are compatible with the specified CN4U-P configuration.
MC4 Compatibility
The CN4U-P Solar Panel Connector is designed as an MC4-compatible PV connector for photovoltaic module and solar cable connections. It is developed to work with compatible MC4-type connection systems and provide a secure electrical and mechanical connection for solar PV applications.
CN4U-P supports up to 1500V DC and 52A, with IP68 protection and contact resistance below 5mΩ, making it suitable for demanding outdoor photovoltaic installations.
However, MC4 compatibility should not be determined by physical fit alone. Electrical, mechanical and certification compatibility must also be considered. For safe and reliable PV system installation, mating connectors should be verified as an approved and compatible combination.
When replacing or matching an existing connector, we recommend confirming the connector manufacturer, model, electrical specifications and certification requirements before installation. TREASUN can provide technical information and compatibility confirmation for specific connector combinations.
