1. Description of system

Solar-grid hybrid power system consists of solar panels, solar module, rectifier module, integrated controller and battery. Among the system, the power of solar panels is more than load power, solar energy is preferred to power the loads,  when solar energy is inadequate, the grid will power the loads, If the grid is power failure, the battery will power the loads, when the gid power is available, the controller will start the grid power to charge the battery.

For solar-grid hybrid power system, the voltage of solar module and rectifier module is controlled to supply power as per the sequence of solar-battery(at high voltage)-grid-battery to maximum utilize the solar energy and reduce the grid consumption.

The solar-grid hybrid power system can be widely used at most occassions in both urban and rural areas, which can save about 30% grid power consumption.
