Hoenergy EFIS-D-W50/100-AIO is an LFP battery energy storage system for commercial and industrial use, with 100.35 kWh nominal energy and about a 2-hour duration. It is supplied as an AC block, uses fan cooling, and has 280 Ah prismatic cells. The unit weighs 1.3 tonnes (2,866 lb).

Use Cases

Hoenergy EFIS-D-W50/100-AIO has nominal energy in the commercial and industrial size class. It connects at 380 V, a low-voltage AC connection, and these specifications indicate use behind the meter.

Capabilities

Hoenergy EFIS-D-W50/100-AIO has a shortest listed configuration of 2 h. That configuration points to capacity value, being counted on as supply when the network is tight, and peak shaving, reducing the peak load at the connection point. The specifications suggest renewable colocation, sitting next to a wind or solar plant and sharing its grid connection, and note that its AC block includes the inverter.

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.
