Envision Energy Smart Liquid Cooled Energy Storage System DC Cabinet Products is an LFP battery energy storage system for commercial and industrial applications, supplied as a DC block. It provides 406 kWh nominal energy in 2, 3 and 4 hour configurations and uses 305 Ah prismatic cells.

Use Cases

The specifications of Envision Energy Smart Liquid Cooled Energy Storage System DC Cabinet Products suggest use behind the meter inside a customer's own electrical installation. By energy capacity, it belongs to the commercial and industrial class.

Capabilities

Envision Energy Smart Liquid Cooled Energy Storage System DC Cabinet Products has a shortest listed configuration of 2 h, which suggests peak shaving, discharging into the hours of highest demand. Its longest listed configuration is 4 h, which makes it a candidate for capacity value, standing in as firm capacity when demand peaks. Its DC block connects through a separate inverter, which points to renewable colocation, operating alongside a wind or solar plant on one site.

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.
