Stand-alone inverter includes power supply system of remote
village,households use solar power system,communication signal
power supply,cathode protection,solar street lamp etc,those
independent power generation system with storage battery.
Photovoltaic(PV)grid-connected power system is connected and
transmitting electric to the power network.The system receives
solar radiation energy through photovoltaic component,after the
high frequency DC conversion,solar radiation is changed into high
voltage DC,then it goes through the inverter and becomes sine wave
AC current which same frequency and phase to the power network.
