Use Cases
The specifications of LONGi Hi-MO One Pro-AC together point to use behind the meter, on the customer's side of the utility connection. Its nominal energy places it in the commercial and industrial size class. It connects at 400 V, a low-voltage AC connection.
Capabilities
LONGi Hi-MO One Pro-AC specifications suggest capacity value, standing in as firm capacity when demand peaks. Its longest listed configuration is 24 h. Its AC block includes the inverter, which points to renewable colocation, operating alongside a wind or solar plant on one site. Its shortest listed configuration is 2 h, which 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.
