e-STORAGE CSI-SolBank-S-PL-5016-4h-EU is a containerized LFP battery energy storage system with 5.016 MWh nominal energy and about a 4-hour duration as a DC block. It uses liquid cooling, has 1.2 MW rated DC power, and delivers 94% DC round-trip efficiency.

Use Cases

Use in front of the meter directly on the electricity network is consistent with the specifications of e-STORAGE CSI-SolBank-S-PL-5016-4h-EU. Its nominal energy places it in the utility-scale size class.

Capabilities

The shortest listed configuration of 4 h makes e-STORAGE CSI-SolBank-S-PL-5016-4h-EU a candidate for capacity value, standing in as firm capacity when demand peaks. Its DC block connects through a separate inverter, and that specification points to renewable colocation, storing output from a wind or solar plant on the same site. The specifications suggest energy shifting, storing charge and releasing it hours later, and list a configuration of 4 h.

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.
