BYD Energy Storage MC12C-B6437-E/U-R4 is a containerized LFP system with 6.431 MWh nominal energy and 1.608 MW rated DC power. It is supplied as a DC block with liquid cooling, operates across a 1081.6 to 1497.6 V DC window, and weighs 53.01 tonnes (116,867 lb).
Use Cases
Use in front of the meter, directly on the electricity network, is consistent with the specifications of BYD Energy Storage MC12C-B6437-E/U-R4. Its nominal energy places it in the utility-scale size class.
Capabilities
A duration of about 4 h at full power, calculated from 6.431 MWh and 1.608 MW, makes BYD Energy Storage MC12C-B6437-E/U-R4 a candidate for energy shifting, charging at one time and discharging hours later, and points to capacity value, counting as firm supply toward a network's peak needs. Its DC block connects through a separate inverter. That configuration suggests renewable colocation, operating alongside a wind or solar plant on one 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.
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.
