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 configured as a complete PV power generation system solution with PV inverter products.
Using the PV combiner box, users can connect a specific number of PV modules of the same specifications into series PV modules according to the input DC voltage range of the inverter. These series are then accessed via the PV array lightning protection box. It is convenient to facilitate the post-inverter process through the output for lightning protection devices and circuit breakers.
