3.1 System introduction
For a large-scale grid-connected PV system, it is widespread to install a DC
combining device between PV modules and inverters to minimize cable
connections, facilitate maintenance and enhance reliability.
Our SunBox PVS combiner box series (PVS) are designed for meeting these
requirements, which provides a turnkey solution for PV plant systems.
Considering different types of PVS, a certain number of PV strings can be
connected to the input side of PVS. After combining work done, at the output
side, there will be one DC+ and one DC- main line. By using of surge protection
device (SPD) and circuit breakers, the output can be connected to inverters
directly.
The PV generation system including a PVS is shown in following figure.
