2.1 Preface
Dear users, thank you for using photovoltaic grid-connected inverter
products manufactured by our company which is experienced in
development of photovoltaic grid-connected generating sets. We hope
this product can meet your demands and welcome you to put forward
more suggestions on performance and functions of this product.
2.2 PV Grid-connected Generating System
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.
