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.
PVS is 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 DC switch, the output can be connected to inverters directly.
The PV generation system including a PVS is shown in following figure.
