5 MWh String PCS Power Container
Grid-ScaleAC Block20 ft containerUpdated Aug 28, 2026
Envision Energy 5 MWh String PCS Power Container is an LFP battery energy storage system supplied as an AC block for utility-scale use. It provides 5.03 MWh nominal energy, uses liquid cooling and 315 Ah prismatic cells, and delivers 99% DC round-trip efficiency.
Use Cases
Envision Energy 5 MWh String PCS Power Container 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, operating alongside a wind or solar plant on one site. It holds about 2 h of storage at full power, calculated from 5.03 MWh and 2.52 MW, which indicate peak shaving, discharging into the hours of highest demand, and grid services, support that helps operators run the electricity network. That configuration makes Envision Energy 5 MWh String PCS Power Container 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.
