A solar energy storage system typically includes components such as solar panels storage batteries, and inverters. lts operation principle is as follows:
Solar panels: Convert sunlight into direct current (DC) electricity. When sunlight isreceived by the solar panels, they generate DC electricity and send it to the storage batteries for storage.
Storage batteries: Store the electricity generated by the solar panels. During the day, the storage batteries can store excess electricity generated by the solar panelsfor use at night or during cloudy weather. When electricity is needed, the storage batteries release the stored energy.
Inverter: Converts the DC electricity stored in the storage batteries into alternatingcurrent (AC) electricity for use. The inverter converts the DC electricity stored in thestorage batteries into AC electricity, which is supplied to household appliances.
