Photovoltaic Lightning Protection Combiner Box

XJ Electric GHL-100 Photovoltaic Lightning Protection Combiner Box

The company's self-developed photovoltaic lightning protection combiner box has successively won bids for key projects in photovoltaic power stations of China Power Investment, CGN, and Huaneng Group. As of now, XJ's market share for photovoltaic lightning protection combiner boxes in China is approximately 20%.

In 2016, XJ Group upgraded and transformed the GHL photovoltaic combiner box production line, significantly enhancing the production capacity of GHL photovoltaic combiner boxes.     

The intelligent photovoltaic combiner box is used to connect photovoltaic modules to inverters. In addition to realizing combiner and lightning protection functions, it also features current, voltage, and temperature measurement inside the box, fault diagnosis for lightning protection, fuses, and photovoltaic strings, as well as communication functions with the main station, facilitating the formation of a photovoltaic power generation monitoring system. It is mainly used in large-scale photovoltaic grid-connected power generation projects.
