Dyness Stack100 S51100 High Voltage Storage Battery 5.12 kWh LiFePO4
The Dyness S51100 is the battery module that makes up the high voltage storage systems of the Dyness Stack100 series. Each module consists of 16 LiFePO4 cells for a nominal voltage of 51.2 V, a capacity of 100 Ah and a nominal energy of 5.12 kWh. The modules are stacked and connected in series, so the tower works at high voltage even though the single module is at 51.2 V.
A Stack100 tower can house from 3 to 15 modules, with system voltages from 153.6 V to 768 V and energy from 15.36 to 76.80 kWh. The module withstands charge and discharge currents up to 100 A (1C), with a peak of 125 A for 2 minutes, and declares a depth of discharge of 95% and over 8,000 cycles. Communication takes place via CAN/RS485 and the system is compatible with numerous high voltage hybrid inverters, including Goodwe, Solis, Deye, Solplanet, Solinteg, Sunways, Hoymiles, SAJ, Growatt, ATESS and Sinexcel.
