BATTERY ENERGY STORAGE SYSTEMS (BESS)
The compact power blocks allow the connection of power cables at input or output of BESS sub-systems control panels such as PCS, central and solar inverters. They combine high

The mobility and flexibility of the system enables novel applications and deployments where BESS previously were unused due to the non-flexible solutions. The system is modular, meaning that the energy storage capacity can be quickly adapted depending on the application case, in contrast to larger and bulkier solutions.
The system is built of two main blocks. The PCS building block, responsible for the main control of the mobile BESS. The nominal power rating of the PCS block is 225 kVA, with a maximum peak power in the peak shaving mode of 275 kW . The second block is the modular battery pack.
If the BESS is in a “dedicated use” building compliant with IFC 1207.7.1, then the kilowatt-hour limits outlined in the table do not apply. This exception is beneficial, especially considering that 600 kWh of energy capacity is approximately equal to a small portable diesel generator's belly tank capacity.
