DC combiner box with SPD

Summary

PVB series PV Array Combiner Box is used for the connected of PV inverter and PV array to lessen the cable for the connecting,easy to maintain and improve the reliability.We always fix the DC convergence device between the PV inverter and PV array.With many years of experience in the PV power system,it is specially designed for the high efficiency and reliability ;it is the supporting components of our PV inverter for the PV power generating.You could connect a certain number of PV components in series to be the PV array according to the voltage range of DC input;then,connect the PV array to PV lighting protection combiner box for the converge, through the output of lightning protection device and breaker,it is easy for switching-in of PV inverter and improve the system safety and lessen the installing time.

  

Product Overview‌

As a key component of a solar power generation system, the PVB series photovoltaic combiner box significantly simplifies the connection architecture between the photovoltaic array and the inverter by combining multiple photovoltaic module inputs into a single output. The product adopts an industrial-grade wall-mounted installation solution, which saves space and facilitates daily maintenance by operation and maintenance personnel. Parameters such as the number of input channels and rated current can be customized according to project requirements to adapt to various photovoltaic power station scenarios. The built-in intelligent protection system includes: diode isolation to prevent reverse current, fuse overcurrent protection, MOV overvoltage absorption device and Type II surge protector, which fully guarantees the stable operation of the system in harsh environments. Its protection level reaches IP65 and the operating temperature range is -25℃ to +60℃, meeting the technical specifications of the mainstream global photovoltaic market.
