LFP CNTE STAR Q is a commercial and industrial battery energy storage system with 109 kWh nominal energy, supplied as an AC block. It has 306 Ah prismatic cells. The system weighs 1.8 tonnes (3,968 lb) and uses air cooling.

Use Cases

CNTE STAR Q has nominal energy in the commercial and industrial size class. It connects at 380 V, a low-voltage AC connection, and is certified to low-voltage grid connection rules (EN 50549-1, VDE-AR-N 4105, NRS 097-2-1). These specifications indicate use behind the meter.

Capabilities

It holds about 2.18 h of storage at full power, calculated from 109 kWh and 50 kW. That configuration indicates capacity value, standing in as firm capacity when demand peaks. For CNTE STAR Q, the specifications suggest renewable colocation, sitting next to a wind or solar plant and sharing its grid connection: its AC block includes the inverter. A 0.5P rating makes CNTE STAR Q a candidate for peak shaving, cutting the power drawn from the grid at peak times.

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.
