WIND SOLAR HYBRID CHARGE CONTROLLER FOR OFF GRID SYSTEM
Off-grid type wind and solar complementary power supply system is mainly composed of wind turbine, solar module, controller, energy storage battery, off-grid inverter, AC DC load and other parts. The system is a composite renewable energy power generation system integrating wind, solar and battery power generation technologies and system intelligent control technology.
Wind turbine
Use wind turbine to convert wind energy into mechanical energy, convert mechanical energy into electrical energy through wind turbine, and then charge energy storage battery through controller
Solar Module
Use the photovoltaic effect of solar modules to convert light energy into electrical energy, and charge the energy storage battery through the controller
Controller
According to the changes of sunshine intensity, wind power and load, the controller continuously switches and adjusts the working state of the storage battery: on the one hand, the adjusted electric energy is sent directly to the DC load. On the other hand, the excess power is sent to the storage battery for storage. When the power generation cannot meet the needs of the load, the controller will send the power from the storage battery to the load, and when the power generation exceeds the needs of the load and the storage battery, the controller will control by PWM to ensure the continuity and stability of the whole system.
Off-grid inverter
Convert the DC power from the energy storage battery into stable AC power to provide AC load, automatically cut off the power supply to the load when the energy storage battery is under-voltage, and automatically provide power supply to the load when the under-voltage is recovered, and also cut off the power supply to the load when the load is short-circuited or overloaded
Energy storage battery
Generally, it is composed of multiple energy storage batteries connected in series and parallel, which play the role of energy regulation and load balancing in the system. The electrical energy output from wind turbines and solar modules is converted into chemical energy and stored for use when the power supply is insufficient in the north.
