MC4 Solar Connectors

CHYT is one of the best suppliers and manufacturers of MC4 Solar Connectors in China. We welcome to wholesale or customized MC4 Solar Connectors from our factory. If you are interested in our product, please contact us quickly! MC4 Solar Connectors are preferred by installers and homeowners because they are easy to use. First, the installer would need to strip the ends of the wires connected to the solar panels. Next, these stripped wires are fitted into the MC4 connector and are locked into place using the special locking mechanism found on MC4 connectors. This locking mechanism ensures that the connection is secure, weather-resistant and cannot be disconnected unintentionally. This also makes repositioning the connectors possible without having to re-wire between the two solar panels which helps you save time and money.

MC4 Solar Connectors are also known for their durability and reliability. Made with high-quality materials such as tin-plated copper and PPO (Polyphenylene Oxide), they can withstand harsh outdoor conditions such as extreme heat, cold and humidity. They can also perform well in high-voltage and high-current applications, making them ideal for large solar power systems.

ICHYTI solar panel cable connectors Parameter (Specification)

 

ICHYTI solar panel cable connectors Performance Requirement

◉ Photovoltaic connectors should have good conductivity, and the contact resistance should not exceed 0.35 milliohms.
◉ It is necessary to have sufficient safety performance to ensure the safety performance of solar cell components. The environment and climate in which solar energy equipment is used can sometimes be extremely harsh, so it must have waterproof, high-temperature resistant, anti-corrosion, high insulation and other performance, and the protection level should reach IP68.
◉ The structure of the solar connector should be firm and reliable, and the male and female connectors that are correctly inserted should have a connection force of not less than 80N. For connection 4mm ² The MC4 connector of the cable should not exceed the upper limit temperature of 105 degrees Celsius when carrying 39A current. The MC4/H4 connector is a single core connector with male and female connectors, which has many advantages such as good sealing, convenient insertion, and easy maintenance and repair.

ICHYTI solar panel cable connectors Installation precautions

When selecting a plug, attention should be paid to product quality, including compliance with the size of the internal metal conductor, material thickness, elasticity, and coating that meet the ability to carry large currents and have good contact. The plastic of the plug shell should ensure a smooth surface without cracks, and the interface should be well sealed. When installing component connectors, it is necessary to avoid exposure to sunlight and rain, in order to avoid aging of the connectors, corrosion of internal connectors and cables, increase of contact resistance, and even ignition, leading to a decrease in system efficiency or fire accidents.

The installation and crimping process of photovoltaic connectors are of utmost importance, and professional crimping tools should be used. Before the construction of photovoltaic power plants, relevant engineering installation personnel should receive training on crimping operations.
