CNTE STAR T-285 is a containerized LFP battery energy storage system, supplied as an AC block with 1.896 MWh nominal energy. Liquid cooling supports 285 Ah prismatic cells. It weighs 35 tonnes (77,162 lb) and operates across a 1164.8 to 1497.6 V DC window.
Use Cases
Use in front of the meter is consistent with the specifications of CNTE STAR T-285. Its nominal energy places it in the utility-scale size class. It is certified to medium- or high-voltage grid connection rules (VDE AR-N 4110).
Capabilities
An AC block with the inverter included makes CNTE STAR T-285 a candidate for renewable colocation, storing output from a wind or solar plant on the same site. It holds about 1.9 h of storage at full power, calculated from 1.896 MWh and 1 MW. That duration points to peak shaving, discharging into the hours of highest demand, and the specifications indicate grid services, work that helps keep the electricity network running.

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.
Site Space Required
Shared: one 3 m aisle serves both neighbours. Dedicated: each unit keeps its own 3 m, so gaps double to 6 m.
Single unit — matches the stored area_sqm convention.
