The Dyness Tower T17 is an enterprise-grade 17.76 kWh high-voltage home battery system (480V) built for high-consumption households and maximum energy autonomy. With an impressive 480V DC nominal voltage and five stackable modules, it delivers exceptional performance with minimal energy loss—ideal for peak demand, high self-consumption and resilient backup integration.

Its robust IP54 enclosure provides installation flexibility for indoor use and protected outdoor locations. The large usable capacity helps you ride through grid outages and peak-load moments with confidence, while keeping your system efficient and future-ready.

  • High capacity: 17.76 kWh for heavy users.
  • Superior 480V HV: Higher efficiency, lower losses.
  • IP54 protection: Indoor & protected outdoor.
  • Cable-free stacking: Clean, fast installation.

High-end energy storage built for the future

  • Maximum efficiency: 480V high-voltage technology minimises resistive losses for optimal overall system efficiency.
  • Plug & play design: The innovative stackable concept eliminates cables between modules for a safer, cleaner and faster installation.
  • Scalable power: The T17 includes 5 modules and can be expanded (up to T21) to reach a total of 21.31 kWh.
  • Proven safety: Premium LiFePO4 cells with intelligent BMS monitoring for safety, temperature and long service life.
Installation notice: High-voltage system (480V DC). Installation must be performed by a certified professional in accordance with local regulations. For inverter selection, ensure support for the 420–547V operating range.
