Basic Configuration

Working principle

The product uses the solar cells which convert solar energy to electrical energy through photovoltaic effect and the wind-driven generator which convert the wind energy to electrical energy. The electrical energy is stored in the battery through the smart controller. When the illumination reduces to *0lux and the solar-cell open circuit voltage is lower than 4.5V, the batteries tart to discharge.

During the days with sunlight, electricity is generated from the solar cell. During the cloudy and rainy days, electricity is from the wind. Together with the solar and wind energy, the integrated system can provide **-hour power to the light. The electricity can be stored by the battery unit and power the light through the controller at nights. The controller ensures the light working and data acquisition.
