2 Product Overview
2.1 Components of PV Grid-Connected System
PV grid-connected system consists of PV modules, PV grid-connected inverters, metering
device and power distribution system. The solar energy is converted into DC via PV
modules, and then the DC is converted into sinusoidal AC which has the same frequency
and phase as the utility grid and fed into the utility grid via inverters.
