For large-scale PV grid-connected power generation system, in order to reduce the connection between the PV module and the inverter, and to facilitate maintenance to improve reliability, it generally need to add DC busbar device between the PV module and the inverter. The PV array lightning protection combiner box is designed to meet this requirement and can be designed to a complete PV power generation system solution with PV inverter products. Using PV combiner box, the user can put certain number of same specifications PV modules into series PV module according to input DC voltage range of the inverter, and then a number of series PV modules access to the PV array lightning protection box. It is convenient to facilitate the post-inverter through the output for lightning protection device and circuit breaker.

Established in 2002, the manufacturing facility is a specialized manufacturer of AC/DC magnetic contactors, definite purpose contactors, AC/DC circuit breakers and Moulded case circuit breakers, Combiner Boxes, PV components products, and more. Located in the industrial zone, we enjoy convenient transportation. The production facility occupies an area of 80,000 square meters and features advanced equipment including injection molding machines, automatic pressers, monitoring stations, and more. The annual production capacity is 100,000 pieces for combiner boxes and 5,000,000 pieces for contactors. With export licenses, products are exported to America, Australia, Europe, South America, and Southeast Asia. The products have gained wide praise at home and abroad. Strict quality control is performed in every procedure from material sourcing, processing, and testing to packing. Our tenet is "Quality First; Improve Technology; Expecting Future".
