LFP battery energy storage system LONGi Hi-MO One Pro-DC is supplied as a DC block for commercial and industrial applications, with 261.24 kWh nominal energy. It supports 2, 4, 6 and 24 hour configurations. The system has liquid cooling and 314 Ah prismatic cells.
Use Cases
Use behind the meter at a customer's own premises is consistent with the specifications of LONGi Hi-MO One Pro-DC. Its nominal energy places it in the commercial and industrial size class.
Capabilities
Its longest listed configuration of 24 h makes LONGi Hi-MO One Pro-DC a candidate for capacity value, counting as firm supply toward a network's peak needs. Its DC block connects through a separate inverter, which points to renewable colocation, sitting next to a wind or solar plant and sharing its grid connection. Its shortest listed configuration of 2 h points to peak shaving, discharging into the hours of highest demand.

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.
