Battery Energy Storage System Explained

The Benefits

Polarium BESS is simple, safe, and smart all the way. The system is made of our high voltage lithium-ion batteries, Battery Management System to guarantee long battery life, UL9540A tested Propagation Protection System, and highly efficient inverters.

Due to its modular design, our system can be tailored to your needs and to different capacities. We offer both a complete turnkey BESS and the possibility to integrate our BESS into a larger system installation and to additional energy sources, such as solar and wind. In any case, we deliver a solution compliant with specific project demands and all required grid codes.

With Polarium BESS, you have full control of your system. Even at a distance. Our Fleet Management enables you to monitor, update and configure your BESS remotely.

Polarium BESS consists of our Battery Cabinets with a capacity of 146 kWh, Inverter Cabinets with one 70 kW bi-directional inverter per Battery Cabinet, and AC-Interface Cabinets that house our Polarium Controller, switch gear with protection devices, contractors, AC fuses, optional rectifiers, and any site-specific equipment needed. All cabinets are fitted for both indoor and outdoor installation.

The BESS is scalable from 146 kWh and 70 kW to 1 MWh and 0.5 MW per system, as well as to 20 MWh and 10 MW at a site.
