JinkoSolar JKE-3440K-2H-LAA is a containerized LFP battery energy storage system supplied as a DC block. It provides 3.44 MWh nominal energy with about a 2-hour duration. The unit uses liquid cooling, 280 Ah prismatic cells, and weighs 35 tonnes (77,162 lb).

Use Cases

JinkoSolar JKE-3440K-2H-LAA has nominal energy in the utility-scale size class. This specification points to use in front of the meter, on the utility's side of the connection.

Capabilities

JinkoSolar JKE-3440K-2H-LAA has a DC block that connects through a separate inverter; that points to renewable colocation, storing output from a wind or solar plant on the same site. The specifications suggest peak shaving, discharging into the hours of highest demand. The shortest listed configuration is 2 h. That 2 h configuration makes JinkoSolar JKE-3440K-2H-LAA a candidate for grid services, support for the operation of the electricity network, and points to capacity value, standing in as firm capacity when demand peaks.

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.
