Goldencell presents ESS power battery system. It is a large source of backup power with energy storage between 50-300KWh. Its primary spare parts comprise of LiFePO4 battery pack, charger, inverter, and protection devices for voltage-stabilization and frequency stabilization power source. It provides a long service life. Other features include quick charging and high current discharging.
ESS is suitable for use in grid substation of cities, storage of wind and solar power, emergency power supply, etc. For example, in emergency power supply, while the grid normally supplies power, the ESS supplies load after voltage stabilization. Simultaneously, the battery gets charged within the ESS and energy is stored in the battery. In case of an unforeseen breakdown of the city grid or an input defect, load is supplied by the UPS by transforming the battery's energy to 220V AC to ensure normal operation.
