Shanghai Sermatec Energy Technology Co has successfully installed a 5.1 MW/17 MWh battery energy storage system (BESS) in Bulgaria for an undisclosed client operating a solar power plant. This installation aims to address the client’s challenge of excess solar electricity generation, which previously resulted in wasted energy during the day and the need to purchase electricity from the grid at night.
The project features 48 units of Sermatec’s EasyCube Series, each equipped with 372 kWh energy storage systems. These cabinet-style units utilize advanced 3.2V 280Ah lithium iron phosphate (LFP) batteries, achieving a conversion efficiency of up to 99% and a design life exceeding 15 years.
This solution enhances energy storage efficiency, reliability, and safety while tackling issues related to solar overproduction. Additionally, the project incorporates Sermatec’s energy management system, which integrates solar generation, manages energy usage during peak and off-peak times, and allows for real-time monitoring. The system also includes a battery management system (BMS) to ensure battery safety and health.
