Dyness Tower T21 S3 Energy Storage System 21,31 kWh LiFePO4 High Voltage
The Dyness Tower T21 S3 is a high-voltage storage system of 21,31 kWh made up of 6 battery modules of 3,55 kWh each plus the BDU control unit and base. Modules stack into a tower and connect by plug, so installation needs no hand-made power wiring.
Cells are LiFePO4, a cobalt-free chemistry that does not go into thermal runaway and withstands thousands of cycles. The BDU talks to the hybrid inverter over CAN and works across a very wide system voltage window, 48 to 1000 V, so it suits most high-voltage hybrid inverters on the market.
Protection is IP54 on both modules and control unit: the system lives in a garage, plant room or cellar with no extra cabinets. Charging is allowed from 0 to 50 °C and discharging from -10 to 50 °C. The system is certified to IEC 62619 and UL 1973.
