DC combiner box for PV Array is installed between PV module and inverter, to reduce connecting line between PV module, DC power distribution cabinet, and inverter. DC combiner box for PV Array have the function of converging lightning protection, the counter-attack, waterproof, monitoring, corrosion pevention etc. withstand voltage ≥1000VDC.
DC combiner box is designed for Large-scale photovoltaic grid-connected power generation system
To reduce the wiring between photovoltaic modules and the inverter,
and improve reliability
