As the global transition to renewable energy accelerates, the demand for reliable and safe solar photovoltaic (PV) system components has never been higher. Wenzhou Shangnuo, a leading manufacturer of low-voltage electrical distribution products, underscores its commitment to this vital sector with its specialized range of high-performance Solar PV Connectors and Combiner Boxes. Manufactured in our 11,532 sqm facility under stringent ISO 9001 quality management and holding relevant IEC and TUV certifications, these products are engineered for longevity, efficiency, and safety in the most demanding environments.

Understanding the critical role connectors and combiner boxes play in system efficiency and fire safety, Wenzhou Shangnuo subjects its solar components to exceptional quality control protocols. Our connectors feature premium materials resistant to UV radiation, extreme temperatures, and moisture ingress, ensuring minimal voltage drop and secure, reliable connections over decades. Compatibility with major industry standards and connector types is a key focus. Similarly, our Combiner Boxes are designed for optimal protection, featuring robust enclosures (IP65 rated or higher), high-quality DC disconnect switches, appropriately rated fuses or circuit breakers (also manufactured by us), and integrated Surge Protection Devices (SPDs) crucial for safeguarding expensive inverters and other downstream equipment from lightning strikes and voltage transients.
