For large-scale PV grid-connected power generation systems, in order to reduce the connection between the PV module and the inverter, and to facilitate maintenance to improve reliability, it generally needs to add a 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 integrated into a complete PV power generation system solution. Using this combiner box, users can connect specific specifications of PV modules in series according to the input DC voltage range of the inverter, facilitating post-inverter operations through lightning protection devices and circuit breakers.
