DC connectors are mainly used in solar photovoltaic systems, battery energy storage devices and DC power lines, responsible for connecting cables and equipment. They feature good electrical conductivity, water resistance, dust resistance, high-temperature resistance and UV resistance. Among them, the MC4 type connector is a common product in the photovoltaic field.

In terms of price: The reference purchase price for ordinary domestic MC4 connectors is approximately 1 to 5 yuan per pair. Products with certifications such as TUV and CE are priced at around 3 to 10 yuan per pair. Products from well-known brands are even more expensive. The specific price depends on the rated voltage, current, material, certification and purchase quantity. The above is only for reference in foreign trade quotations.

Requirements of different countries

Europe: Generally, compliance with the IEC 62852 standard is required, and attention is paid to the CE marking, TUV certification, as well as the water resistance and weather resistance of the product.

In the United States, the main focus is on UL 6703 or UL 62852 standards, and it is necessary to comply with local photovoltaic electrical installation regulations.

In the Middle East region, high temperatures, sandstorms and strong ultraviolet environments should be given priority consideration. Attention should be paid to the heat resistance, protection level and long-term stability of the products.

Other countries: Certification standards should be confirmed in accordance with the regulations of the importing country and the requirements of the project.

When exporting for foreign trade, it is recommended to confirm the voltage, current, wire diameter, certification and compatibility of the connector brand with the customer in advance to avoid the risk of return or installation due to non-compliance with specifications.
