Use Cases
Use in front of the meter is consistent with the specifications of WHES IA-744 kW/1490kWh-DA10. Its energy capacity places it in the utility-scale class, and it is certified to medium- or high-voltage grid connection rules (EN50549-2).
Capabilities
The shortest listed configuration, 4 h, makes WHES IA-744 kW/1490kWh-DA10 a candidate for capacity value, counting as firm supply toward a network's peak needs. Its AC block includes the inverter and points to renewable colocation, storing output from a wind or solar plant on the same site. The specifications suggest energy shifting, charging at one time and discharging hours later, and list a configuration of 4 h.

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.
