Spanish energy storage specialist Cegasa presented EScal HV, its new modular and scalable battery, at Intersolar. The company claims that the new solution will address an unmet demand for high-voltage systems at industrial and commercial levels.
The new system offers installations from 17 kWh to 350 kWh using a stackable system that allows up to 15 modules in series and four strings in parallel.
The minimum string consists of three modules with a total capacity of 17 kWh and a nominal voltage of 173 V. The maximum string consists of 15 modules with a capacity of 86 kWh and a nominal voltage of 864 V.
It allows up to four strings to be connected in parallel per 60-module system, expanding the capacity to 344 kWh.
The rated power of a basic string consisting of three modules is 9 kW; it weighs 175 kg and measures 706 mm x 375 mm x 870 mm.
