Autarsys Mini ESS

The Autarsys Mini 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 is rated at 40 to 120-kW of power and has an energy storage capacity between 33 and 302-kWh, depending on the cell type and the application of the ESS. It is insulated within an 8-ft. (2.44m) storage container that protects it from harsh elements.

The military grade air conditioning system allows the Mini 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.
