Autarsys Medium ESS

The Autarsys Medium is a modular Energy Storage System (ESS) that serves a variety of applications. As a turnkey solution, we can integrate the Mini into both off-grid and on-grid settings. Whether combined with conventional -such as diesel- or renewable- like photovoltaic, wind, or biogas- energy sources, the Mini’s intelligent energy management system (iEMS) can be tailored to any energy set-up.

The system has a rated power of 100 to 800-kW and an energy storage capacity between 65 and 1092 kWh, depending on the cell type and the application of the ESS. It is insulated within a 20-ft. (6.1m) storage container that protects it from harsh elements. 

The military grade air conditioning system allows the Medium ESS to operate under ambient temperatures of up to 55°C. Because of the optimally designed container, the battery and inverter suppliers offer an extended warranty of up to ten years.
