QC Solar 3Qxy Negative Integration

3Q negative pole integrated junction box is a solution specially designed for the sea surface photovoltaics. Its unique integrated design skillfully separates the contact between the connector and the water surface, thus ensuring the stable operation of the junction box in the sea surface environment. This junction box not only has a delicate appearance and a small size, but also has a strong rated current capacity, covering multiple gears such as 20A, 22A, 25A, 30A, and 35A. Users can flexibly switch according to actual needs, easily meet the diverse needs of various photovoltaic systems, and provide strong guarantee for the safe and efficient operation of the sea surface photovoltaic system.

In terms of safety, the 3Q negative pole integrated product also performs exceptionally well. The upper cover adopts the anti-mistake design for preventing stupidity and covering the lid wrongly, which effectively avoids misoperations during the installation process. At the same time, the full three-dimensional gel filling and coating design protects the electrical components in all directions to prevent the risk of electrical exposure and short circuit. In addition, the small structure design and small hot spot shading allow the power generation efficiency of the photovoltaic panel to be further improved.

The gel filling amount of this junction box is small, which not only reduces the production cost, but also enhances the reliability of the product. The quick and convenient current switching greatly simplifies the operating process, improves the work efficiency, shows its precise cost control, and also takes into account the convenience of operation, making the product highly competitive in the market.

From the perspective of mass production, the structure design of the 3Q negative pole integrated product is simple and convenient for large-scale, stable mass production in multiple factories, multiple bases, and multiple countries. This feature enables the product to quickly respond to market demands and provide strong support for the rapid development of the photovoltaic industry.

In addition, 3Q negative integrated products have passed the TUV/UL dual 1500V certification with rated voltage of IEC1500V/UL1500V, which ensures stable operation under various harsh environmental conditions. This authoritative certification not only reflects the excellent quality and reliability of QC Solar (301278) products, but also provides a strong guarantee for its worldwide application. 3Q negative integrated junction box is the preferred product for sea surface PV junction box.
