It provides 5.015 MWh nominal energy as a DC block with liquid cooling. The unit uses 314 Ah prismatic cells, weighs 42 tonnes (92,594 lb), and operates across a 1164.8 to 1497.6 V DC window.","Use in front of the meter is consistent with the specifications of Sermatec SMT-ESS-L20CB-5015CE-C. Its nominal energy places it in the utility-scale size class. It supports IEC 61850, used in utility control systems.","About 2 h of storage at full power, calculated from 5.015 MWh and 2.50794 MW, makes Sermatec SMT-ESS-L20CB-5015CE-C a candidate for grid services, support that helps operators run the electricity network, and points to capacity value, being counted on as supply when the network is tight. Its DC block connects through a separate inverter, and the specifications suggest renewable colocation, storing output from a wind or solar plant on the same site. That duration points to peak shaving, cutting the power drawn from the grid at peak times.","2026-08-28T10:19:51",5.02,"MWh",5015,"kWh",null,2.51,"MW",2507.94,"kW",1,"Outdoor-capable",1331.2,"V",1164.8,1497.6,2438,6058,2896,"mm",8,19.88,9.5,95.98,238.5,114.02,"in",42,"t",42000,"kg",92594,"lb","LFP",314,"Ah","Prismatic","BatteroTech",[133],"IP55","Aerosol
