5.015 MWh nominal energy, EVE Energy EVE S556H201 is a containerized battery energy storage system supplied as a DC block. It weighs 45 tonnes (99,208 lb) and operates across a 1164.8 to 1497.6 V DC window.
Use Cases
The specifications of EVE Energy EVE S556H201 suggest use in front of the meter, connected to the utility network itself. Its nominal energy places it in the utility-scale size class.
Capabilities
For EVE Energy EVE S556H201, the specifications suggest peak shaving, reducing the peak load at the connection point. It is rated at 0.5C. That rating makes it a candidate for grid services, work that helps keep the electricity network running. Its DC block connects through a separate inverter, which points to renewable colocation, storing output from a wind or solar plant on the same site.

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.
