Product Overview
For large-scale PV grid-connected power generation systems, the PV array lightning protection combiner box is essential for reducing the connection between PV modules and inverters. It facilitates easier maintenance and significantly improves system reliability. This device acts as a DC busbar, allowing multiple series PV modules of the same specification to be integrated safely before outputting to the inverter through lightning protection devices and circuit breakers.
