The design of the Storion Smile 5 energy storage unit recalls the cuboids and blocks from the computer game Tetris. This modular design lends the device a distinctive appearance and allows easy assembly and disassembly of the individual battery elements. Storion Smile 5 can be monitored and controlled via an app. The system’s integrated uninterruptible power supply (UPS) guarantees a reliable supply even in the case of a power failure.
