261kWh Energy Storage System

SMT-ESS-CUBE261CE


The 261kWh outdoor energy storage cabinet, model SMT-ESS-CUBE261CE, is designed to meet industrial and commercial energy storage needs. The cabinet features multiple electrical safety designs, including an emergency shutdown (E-STOP), insulation de- tection, water ingress protection, lightning protection, and other safety functions. The fire protection system supports active explosion preven- tion and aerosol fire extinguishing to ensure product safety. It inte- grates local EMS functions, supports various energy management strategies, and meets the application scenarios of photovoltaic con- sumption, peak-valley arbitrage, demand control, and electricity market trading, promoting the development of commercial and industrial energy storage.
