Sermatec EASYCUBE Series 261kWh SMT-ESS-CUBE261CE is an LFP system for commercial and industrial use, supplied as an AC block. It provides 261.24 kWh nominal energy with about a 2-hour duration, uses 314 Ah prismatic cells, and delivers 87% AC round-trip efficiency.
Use Cases
Use behind the meter is consistent with the specifications of Sermatec EASYCUBE Series 261kWh SMT-ESS-CUBE261CE. It falls within the commercial and industrial class by energy capacity. It connects at 400 V, a low-voltage AC connection, and is certified to low-voltage grid connection rules (EN50549-1).
Capabilities
The shortest listed configuration of 2 h makes Sermatec EASYCUBE Series 261kWh SMT-ESS-CUBE261CE a candidate for capacity value, standing in as firm capacity when demand peaks, and peak shaving, reducing the peak load at the connection point. Its AC block includes the inverter. That points to renewable colocation, storing output from a wind or solar plant on the same site.

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.
