The VKCB lightning protection combiner box combines the DC input and sink of 2，3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 24, 30,36, 48 PV modules to 1 output, each channel is equipped with a fuse, and the output is equipped with a lightning arrester and a circuit breakerThe input wiring of the DC power distribution cabinet and the inverter is greatly simplified. Provide lightning protection, short circuit protection and grounding protection.The combiner box is divided into two types, intelligent and non-intelligent. The intelligent lightning protection combiner box is equipped with a sink monitoring unit. It can monitor the current input from each photovoltaic cell string, the summed output voltage, the temperature inside the box, the status of the lightning arrester, and the status of the circuit breaker.Design and configuration are strictly accordances with the requirements of “Technical Specification for Photovoltaic Confluence Equipment” CGC/GF 037:2014. Provide users with security, concise, beautiful, and suitable photovoltaic system products. The product is wall-mounted and can be adapted to a variety of harsh environments. In addition to the relevant core components. Others can be customized according to user requirements.
