Availability :

The photovoltaic grid-connected generating system is composed of solar cell module, grid-connected inverter, metering devices and power distribution system (as shown in Figure 1). The solar energy is converted to DC electric power through solar cell module, which is further converted to sine-wave current synchronous with grid frequency and phase via grid-connected inverter. Such electric power is then fed into power grid. The photovoltaic grid-connected inverter is the key equipment in solar power system.
