AllGood AG-DK-PV Solar PV Combiner Box with Lightning Protection
AllGood AG-DK-PV Solar PV Combiner Box with Lightning Protection is used for large-scale PV grid connected power generation power system, in order to reduce the connecting lines between PV modules and inverter, easy maintenance and improve the reliability, generally it needs to increase the DC bus system between photovoltaic modules and inverter. This PV combiner box is specially designed to meet this requirement, it can match with inverter products to compose complete PV system solution. DK-PV series PV combiner box, there are Surge Protective Device(SPD)in the output terminal, which can protect the DC fuse cutout of the PV combiner box, inverter and other terminal equipments, to ensure the whole PV power generation system operate long-term and steadily.

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. AG-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.
AG-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.
