As a new type of clean energy, solar energy is highly praised by environmentalists, but "the moon is cloudy and sunny, and the sky is windy and rainy", what should we do when there is no sun? Solar batteries exist for this situation.
Photovoltaic off-grid power generation system is a power generation system that uses the principle of photoelectric effect to convert solar energy into electrical energy. It usually consists of solar cell components, controllers, battery packs, and DC/AC inverters.
According to the plan, the role of the solar cell module is to convert solar energy into electrical energy, supply the load to work or charge the battery pack; the role of the controller is to protect the charging and discharging of the battery pack; the battery pack is used to store electrical energy; the role of the inverter is to Convert direct current to alternating current. At night or in cloudy and rainy days, when the solar cell module cannot work, the battery pack supplies power to the load to work.
The working mode of the battery can be divided into two types: cyclic use and floating charge use. Often in the state of frequent charging and discharging, that is, cyclic use; often in the state of charging, it is used for floating charge, which can make up for the capacity loss caused by the self-discharge of the battery. The VRLA battery used in the photovoltaic power generation system belongs to the recycling mode.
