QC Solar 3Qxy Vertical 

1. The vertical outlet design is more convenient for installation and will not touch the aluminum frame of the module during installation;
2. Excessive bending of cables in the traditional way of exiting leads to cable failure; vertical exiting can protect the cables and reduce the risk of cable failure.
3. Integrated module design, the same box body, the same module meets multiple current needs;
4. The cable and the copper plate adopt resistance welding welding technology, which is reliable in connection and higher stability.

QC solar 3Qxy Vertical Outlet junction box is a revolutionary product that combines innovation and functionality to offer you an exceptional electrical connection solution.

This junction box features a modular design with a small box body and a compact structure. This not only reduces the amount of glue filling but also minimizes shadow occlusion, making it more efficient and aesthetically pleasing. The smaller size and compact design also mean it takes up less space, providing more flexibility in installation.

The vertical outlet design is a significant advantage. It makes the installation process much more convenient as it eliminates the hassle of dealing with awkward angles and ensures that the aluminum frame of the module is not touched during installation. This saves time and effort, reducing the potential for damage and ensuring a smooth installation.

In traditional cable exiting methods, excessive bending often leads to cable failure. However, with the vertical exiting of the 3Qxy junction box, cables are well-protected, significantly reducing the risk of failure. This feature prolongs the lifespan of the cables and enhances the reliability of the entire electrical system.

The integrated module design is another standout feature. With the same box body and module, it can meet multiple current needs. This eliminates the need for multiple types of junction boxes, simplifies inventory management, and reduces costs.

Finally, the cable and the copper plate adopt resistance welding technology. This ensures a reliable connection and higher stability, reducing the possibility of loose connections and electrical faults.

In conclusion, the QC solar 3Qxy Vertical Outlet junction box is a game-changer in the field of electrical connections. Its numerous advantages make it a reliable, efficient, and cost-effective choice for all your electrical connection needs.
