PV Grid-Connected Power System
PV grid-connected power system includes PV modules, grid-connected inverter, meter and power switch board. The PV modules convert the solar energy to the DC power, then the grid-connected inverter the DC power to the sine wave AC power which has the same frequency and phase with the grid voltage. The AC power feed in the grid partly and the other powers supply the local loads.
