For commercial and industrial use, Ampace UniC AG440 Internal Inverter 2H System is an LFP battery energy storage system supplied as an AC block. It stores 440 kWh of nominal energy for about a 2-hour duration. The system has pack liquid cooling, PCS air cooling and 530 Ah prismatic cells.
Use Cases
Use behind the meter is consistent with the specifications of Ampace UniC AG440 Internal Inverter 2H System. Its nominal energy places it in the commercial and industrial size class. It connects at 400 V, a low-voltage AC connection.
Capabilities
Its shortest listed configuration is 2 h, which makes Ampace UniC AG440 Internal Inverter 2H System a candidate for capacity value, counting as firm supply toward a network's peak needs, and suggest peak shaving, cutting the power drawn from the grid at peak times. Its AC block includes the inverter and points to renewable colocation, sitting next to a wind or solar plant and sharing its grid connection.

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.
