For large-scale PV grid-connected power generation systems, DC busbar devices are essential between PV modules and inverters to reduce connections, simplify maintenance, and enhance reliability. This PV array lightning protection combiner box is engineered to meet these requirements, providing a complete solution for PV power generation systems. Users can configure a specific number of PV modules in series based on the inverter's DC input voltage range, connecting them to the lightning protection box for centralized output control via circuit breakers.
