As the world embraces the importance of reliable and low-risk renewable energy storage systems, wind power plants and dams are becoming popular sources. However, a backup power supply is still essential, which is why we utilize ESS batteries. ESS stands for energy storage systems, where battery cells are organized based on power supply ratings to serve as reliable backups. Additionally, ESS technologies can power portable devices like solar air conditioners, dehumidifiers, and other low-power devices.
