In order to reduce the wire connections between PV arrays and inverters, and for better maintenance and reliability of PV power generation system, a confluence device is usually needed. Based on years of design experiences, Clenergy developed ISCB series string
combiner box. ISCB series string combiner box collects the multiple DC outputs from solar panels. With this advantage, the front connections in inverters are greatly reduced. In addition, ISCB is able to enhance the efficiency, safety and reliability of the system by monitoring status of components’ output and providing system protection and fault alarm. By working with Clenergy grid connected inverters, the PV power generation system solution is completed and perfected.
