Solar Panel Electrical Connectors Manufacturer Form China

Features and Advantages

♦ Safety-Lock Design: Uses an easy snap-in locking mechanism for a firm and reliable connection; fast and easy installation with many solar connectors.
♦ High-Density Silicone Material: Heat resistance, flame retardancy, functions of waterproof and dustproof contribute to long performance in a tough environment.
♦ Waterproof and Dustproof Function: Equipped with high-density waterproof rubber rings, excellent quality of silicon materials, IP67 class protection for diversified weather conditions.
♦ Thickened Copper Core: The solder-plated copper core is excellent in conductivity, with oxidation resistance. The contact resistance can be as low as 0.5mΩ to guarantee efficient current transmission.
♦ Support High Rated Voltage and Current: It features high-rated voltage up to 1000V DC and high-rated current up to 45A, making the connector a perfect application for large-scale photovoltaic establishment
♦ Wide Temperature Adaptability: Operating at a temperature as low as -40°C and as high as +90°C, while the maximum temperature can reach +105°C, thus making it very adaptable to different environmental conditions.
♦ High Flame Retardancy: It involves UL-94-V0-grade flame retardant and hence meets the demands for safety in high-temperature or fire-prone environments.

Main Applications

Solar panel electrical connectors can be applied to a wide range of uses in photovoltaic power generation systems, including-but not limited to-the following scenarios:

Residential Solar Power Systems: These will be used in rooftop solar panel connections to the grid or inverter for conversion and transmission of power.

Commercial Solar Power Plants: These connectors will find large-scale applications in solar power projects that connect solar panel arrays for effective power transmission.

Industrial Solar Applications: Solar panel electrical connectors can be applied to industrial-scale solar power stations and solar-powered systems.

Maintenance and Care

♦ Regular Inspection: Regularly inspect the contact resistance of the connector in order to ensure that its conductivity is within a normal range.
♦ Cleaning Waterproof Rubber Rings: Clean waterproof rubber rings frequently, because building up dust or other particles may interfere with the sealing.
♦ Check Safety Lock: Check the locking mechanism for stability with a view to ensuring reliability in the connections even after periods of time.
♦ Pay attention to the correct positive and negative terminal connections before installation to avoid system polarity errors that may lead to malfunction.
♦ Protect from Sun and Rain: Where possible, avoid heavy sunlight and rain to help extend the life of the connector.
♦ By following the steps outlined below, the service life of solar panel electrical connectors can be prolonged to ensure the stability of a photovoltaic system.
