Utility-scale Freqcon BESS MAX PB.4 8.8 MW / 37.5 MWh is a containerized LFP battery energy storage system supplied as an AC block. It uses liquid cooling and has about a 4.26-hour duration. Its round-trip efficiency is 98.3% AC and 99.4% DC.
Use Cases
Freqcon BESS MAX PB.4 8.8 MW / 37.5 MWh has nominal energy in the utility-scale size class and certification to medium- or high-voltage grid connection rules (VDE 4110). It ships as a block of 7 containers. These specifications indicate use in front of the meter.
Capabilities
Freqcon BESS MAX PB.4 8.8 MW / 37.5 MWh lists a 4.26 h configuration. That configuration points to capacity value, being counted on as supply when the network is tight, and energy shifting, charging at one time and discharging hours later. Its AC block includes the inverter, which suggests renewable colocation, storing output from a wind or solar plant on the same site.

Plant Round-Trip Efficiency
The calculator estimates the full "plant" round-trip efficiency (RTE) at the point of interconnection. Some values are pre-blocked depending on information on a particular ESS. The rows that are marked "each way" are one-way efficiencies; they are applied on charge and again on discharge. We then square them. To enter a bundled PCS efficiency value, use its rated-power value, not peak. If the PCS skid already includes the LV/MV transformer, set Transformer LV/MV to 100 % so those losses are not counted twice.
