WHES IA-1116 kW/2230kWh-DA10 is a containerized LFP battery energy storage system supplied as an AC block, with 2.236 MWh nominal energy and 4-hour duration. Air or liquid cooling supports 1.092 MW rated DC power. The system weighs 24.8 tonnes (54,675 lb).

Use Cases

WHES IA-1116 kW/2230kWh-DA10 has an energy capacity in the utility-scale class. It is certified to medium- or high-voltage grid connection rules (EN50549-2). Together these specifications indicate use in front of the meter.

Capabilities

Its AC block includes the inverter; that configuration points to renewable colocation, storing output from a wind or solar plant on the same site. The listed configuration of 4 h suggests energy shifting, charging at one time and discharging hours later. The shortest listed configuration of 4 h makes WHES IA-1116 kW/2230kWh-DA10 a candidate for capacity value, counting as firm supply toward a network's peak needs.

Both measured at the grid connection point. The plant's own power use is already included in the losses.

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.
