4. Product Information
FL5.2 photovoltaic energy storage system is a 48V energy storage system based on
lithium-ion ferrous phosphate battery. It is equipped with a customized battery management system
(BMS), which is designed for energy storage applications of household photovoltaic power generation
users. In the daytime, the surplus power of photovoltaic power generation can be stored in the battery. At
night or when necessary, the stored energy can be provided to the electrical equipment, it can improve
the use efficiency of photovoltaic power generation, peak-load shifting, and provide emergency standby
power.
