On-Grid PV Inverter 3500W/5000W
On-Grid PV Inverter3500W/5000W
The photovoltaic (PV) grid inverter is the coreequipment in the PV grid power station. It has high reliability, efficiency and security. It has a direct bearing on the power capacityof the power station and operation.
The solar PV grid power system is composed of PV modules,metering device, grid inverter and distribution system. The PV module transforms solar energy into DCpower and the grid inverter transforms DC power into sine wave current with thesame frequency and same phase of electricity grid and puts it into anelectricity grid.
This system is the developing trend of solar PV power,which is the most attractive energy utilization technology in 21stcentury. It is able to put energydirectly into the electricity grid without an energy storage battery. It allows full use of electric power fromrenewable energy, decreasing the energy loss and reducing the cost ofsystem. It uses both mains power andrenewable energy as power supply for the AC load, thereby reducing the loadpower shortage rate of the entire system. The renewable energy grid system is used for peak modulation against thepublic electricity grid.
