DYNESS Stack100 (15kWh) to 921kWh parallel expandable

Dyness STACK100

The Dyness STACK100 is a versatile, modular energy storage system (ESS) designed for both residential and commercial and industrial (C&I) applications. The system offers flexibility, high safety, and scalability.

Features & Functionality

• Modular design & scalability
  Each STACK100 unit (or cluster) consists of 3 to 15 modules, each with a capacity of 51.2 V / 100 Ah . For one cluster, this provides an energy storage of 15.36 to 76.8 kWh . Multiple clusters can be operated in parallel (up to 12 clusters), allowing the total capacity to be expanded to approximately 921.6 kWh .

• Battery technology
  The STACK100 uses LiFePO₄ (lithium iron phosphate) cells, known for their safety, stable performance and long lifespan.

• Charging and discharging capacity
  The standard recommended value is 0.5C (charge/discharge current 50A) with a maximum of 1C (100A) for both charging and discharging.
  A peak discharge current is also possible (~1.25C) for short duration (at ~25 °C).

• Depth of Discharge (DoD)
  The STACK100 supports up to ~95% DoD.

• Temperature range

  • Charging: 0 °C to 55 °C

  • Discharge: –20 °C to 55 °C (self-heating option)

• Safety & fire protection
  Each module is equipped with an aerosol fire extinguishing system, which reacts within approximately 5 seconds in case of overheating.
  Cooling: Forced air cooling (forced wind cooling) to promote temperature stability.

• Communication & Control
  Equipped with communication ports such as CAN and RS485. Built-in Wi-Fi module with OTA (Over-The-Air) firmware updates and app-based monitoring.

• Lifespan and warranty
  ≥ 8000 cycles / 10 year warranty.

• Physical properties
  • Weight per module: approx. 47 kg.
  • Cluster dimensions (with max. number of modules): approximately 591 × 390 × 1700 mm (with 11 modules) for a complete cluster.
  • Protection degree: IP20 in many specifications; pay attention to environment during installation (indoor use / sheltered).

Applications

The STACK100 is suitable for various scenarios, including:

• Households that want to store solar energy and maximize their own consumption.

• Small and medium sized businesses / shops / farms / light industry requiring reliable storage capacity.

• Situations where expandability is important — start with a smaller capacity and expand later without purchasing entirely new units.

• Locations with cooling issues or where temperature fluctuations pose a challenge, thanks to air cooling and potential self-heating options.

• Use as an emergency power supply or as a buffer in case of grid unreliability
