BESS PowerBox 1.2 MW/2 MWh, 690 VAC
Grid-ScaleAC Block20 ft containerUpdated Aug 28, 2026
Capture Energy BESS PowerBox 1.2 MW/2 MWh, 690 VAC is a containerized LFP battery energy storage system. It provides 2.064 MWh nominal energy at about a 2-hour duration and uses an AC block. Forced air and integrated HVAC cool its 280 Ah prismatic cells, and the system weighs 26.5 tonnes (58,422 lb).
Use Cases
Use in front of the meter is consistent with the specifications of Capture Energy BESS PowerBox 1.2 MW/2 MWh, 690 VAC. Its nominal energy places it in the utility-scale size class, and it is certified to medium- or high-voltage grid connection rules (EN 50549-2).
Capabilities
Its AC block includes the inverter, which points to renewable colocation, storing output from a wind or solar plant on the same site. Its shortest listed configuration is 2 h, which points to peak shaving, discharging into the hours of highest demand. For Capture Energy BESS PowerBox 1.2 MW/2 MWh, 690 VAC, the specifications suggest grid services, support for the operation of the electricity network, and that configuration 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.
