Short Description:

The battery energy storage system (BESS) containers are based on a modular design. They can be configured to match the required power and capacity requirements of client’s application. The battery energy storage systems are based on standard sea freight containers starting from kW/kWh (single container) up to MW/MWh (combining multiple containers). The containerised energy storage system allows fast installation, safe operation and controlled environmental conditions.

The energy storage system (BESS) containers are designed for neighbourhoods, public buildings, medium to large businesses and utility scale storage systems, weak- or off-grid, e-mobility or as backup systems. The energy storage system containers make it possible to store the energy produced by photovoltaics, wind turbines, or CHP. Due to its high cycle lifetime, The energy storage system containers are also used for peak-shaving, thereby reducing the electricity bill.

Our containerised energy storage system (BESS) is the perfect solution for large-scale energy storage projects. The energy storage containers can be used in the integration of various storage technologies and for different purposes.
