Problems solved by technology

However, the negative pulse voltage will be consumed on the charge and discharge control device, causing the charge and discharge control device to generate heat, thereby reducing the service life of the charge and discharge control device
Moreover, the negative pulse voltage consumed by this part of the heat also causes a waste of energy and reduces the utilization efficiency of solar energy.

Abstract

The invention relates to a solar energy storage system which comprises a solar panel, a charge-discharge control device, a main energy storage device, a trigger unit, an inverter and an auxiliary energy storage device. The solar panel is used for collecting solar energy and converting the solar energy into electric energy. The charge-discharge control device is connected between the solar panel and the main energy storage device. The charge-discharge control device is used for converting a DC (direct current) voltage output by the solar panel into a positively and negatively alternate pulse voltage and charging the main energy storage device by using a positive pulse voltage, wherein the positively and negatively alternate pulse voltage comprises the positive pulse voltage and a negative pulse voltage. The trigger unit is connected with the charge-discharge control device and the inverter. The trigger unit is used for switching on the inverter in the time period of the negative pulse voltage. The inverter is connected to the auxiliary energy storage device. The inverter is used for converting the negative pulse voltage into the negative pulse voltage and charging the auxiliary energy storage device. The invention also provides a driving method of the solar energy storage system.
