Product Description
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 with PV inverter products. Using the PV combiner box, users can connect a certain number of PV modules of the same specifications in series according to the input DC voltage range of the inverter, facilitating post-inverter output for lightning protection and circuit breaking.
