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 Fig. 3-1.
