LG Energy Solution Vertech JF2 4HR AC LINK is a containerized LFP battery energy storage system supplied as an AC block. It provides 5.11 MWh nominal energy at about a 4-hour duration. The unit uses liquid cooling and weighs 48 tonnes (105,822 lb).
Use Cases
LG Energy Solution Vertech JF2 4HR AC LINK has nominal energy in the utility-scale size class. That specification points to use in front of the meter on the utility's side of the connection.
Capabilities
Its AC block includes the inverter, which points to renewable colocation, sitting next to a wind or solar plant and sharing its grid connection. LG Energy Solution Vertech JF2 4HR AC LINK lists a configuration of 4 h, and the specifications suggest energy shifting, storing charge and releasing it hours later. Its shortest listed configuration is 4 h, which makes it a candidate for capacity value, standing in as firm capacity when demand peaks.

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.
