On January 11, 2023, the 2.88MW/7.296MWh battery energy storage system for Kansai Electric Power Project of Japan, supplied by Vilion, was successfully shipped in the factory in Shenzhen. The project includes 6 sets of 480kW/1216kWh 3rd-generation Containerized Energy Storage System---EnerCube, which will connect to the 3.5MW PV, and the system has the functions of on-grid & off-grid operation and switching. In the on-grid mode, the solar + storage system participates in the regulation of the power market and realizes the application of peak-load shifting and virtual power grid. In the off-grid mode, the solar + storage system will work as an intelligent microgrid to supply power to the area independently, and solve the problems of power outage, production shutdown and suspension of the industrial and commercial enterprises and users in the area.
