Output Lightning Protection
When lightning occurs, ordinary combiner boxes tend to appear large scale fusing phenomenon for the DC fuse, which can influence for the whole power system to
work normally, or ever can lead to the equipments damages. DK-PV serial PV lightning
protection combiner box, its input terminal has discharge device which can effectively
protect the DC fuse from the damage of lightning over-voltage and over current, to make
surge the PV power system can long-term work steadily.
Anti-Reflection Function
DK-PV serial lightning protection combiner box is designed with large power anti
diode which make it can long-term work steadily in the harsh environment such as high
temperature environment, and can make sure when the PV array is covered or occurs
damages, it can prevent the countercurrent phenomenon and avoid the damages of PV
array.
Application Scope
Lightning protection of solar power plant, PV array yard.
