PotisEdge PotisBank-L5.0-1500 is a containerized LFP battery energy storage system with 5 MWh nominal energy and 2 and 4 hour configurations. It is supplied as a DC block with liquid cooling and 94% DC round-trip efficiency. The system uses 314 Ah prismatic cells and weighs 41.5 tonnes (91,492 lb).
Use Cases
PotisEdge PotisBank-L5.0-1500 has nominal energy in the utility-scale size class. Its supported protocols include IEC61850 and IEC104, used in utility control systems. Together these specifications indicate use in front of the meter.
Capabilities
PotisEdge PotisBank-L5.0-1500 lists configurations up to 4 h and points to energy shifting, taking in power and returning it hours later. Its longest listed configuration is 4 h, and the specifications suggest capacity value, standing in as firm capacity when demand peaks. Its DC block connects through a separate inverter, making PotisEdge PotisBank-L5.0-1500 a candidate for renewable colocation, sitting next to a wind or solar plant and sharing its grid connection. Its shortest listed configuration is 2 h, which points to peak shaving, discharging into the hours of highest demand; the specifications indicate grid services, support for the operation of the electricity network.

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.
