太阳能并网逆变器PV Grid-Connected inverter
光伏并网发电系统：grid-connected PV system
光伏并网发点系统由光伏组件、并网逆变器、计量装置及配电系统组成（如下图所示）。太阳能能量通过光伏组件转化为直流电力，再通过并网型逆变器将直流电能转化为与电网同频率、同相位的正弦波电流，一部分给当地负荷供电，剩余电力馈入电网。
grid-connected PV system consists of PV modules, grid-connected inverter, metering devices and distribution system components（as shown on the diagram）. The solar energy is converted into DC current by PV modules and then feeding into the local power grid network by the grid-connected in inverters which synchronized the frequency,phase and pure sine waveform with the power network..the synchronized power is partially used for local load demands while the rest power is fed-in the power network.
