3 Configuration of the PV Power Generation System
Overview of Basic System
The PV inverter converts DC power generated by PV modules into AC power and supplies it to the AC grid.
1
Photovoltaic (PV) modules
This converts photovoltaic (PV) energy into DC power.
A group of solar cells makes up PV modules.
A group of PV modules is called a PV array.
2
DC disconnector
At the bottom of the PV inverter, the DC disconnector disconnects/connects
the circuit on the PV side.
3
PV inverter
Converts the DC power generated in the solar cell into AC power.
4
AC disconnector
Installed between the grid and the PV inverter, the AC disconnector
disconnects/connects the circuit on the grid side.
5
Ground-fault current interrupter (GFCI)
Installed between the grid and the PV inverter, this device blocks current
leakage.
