The Dyness Tower S3 Series BMS & Base Unit serves as the updated, central management platform for your high-voltage (HV) energy storage system. This advanced Battery Disconnect Unit (BDU) handles the intelligent communication, real-time monitoring, and active balancing of the Tower S3 battery modules. The package includes the complete set: the premium BMS unit alongside the sturdy Base for secure ground-mount deployment. Boasting an IP54 protection rating, this compact system is ideal for installation inside technical rooms, garages, or sheltered outdoor environments.

  • Complete S3 Set: Supplied directly with the newly refined S3 BMS unit and its matching Base plate.
  • IP54 Certified: Dust and splash-water resistant, granting flexibility for indoor or outdoor installations.
  • HV System Voltage: Engineered to support a wide operating range from 168V to 648V DC.
  • Modular Design Match: Specifically tailored for the Dyness Tower S3 system configurations (TS7, TS10, TS14, TS17, and TS21).

Intelligent S3 Battery Control & Seamless Parallelization

The Tower S3 Battery Controller comes fully integrated with a robust DC main breaker and a physical WAKE button to safeguard startup procedures and manage short-circuit hazards. This modernized S3 platform eliminates the need for complex secondary master controllers: up to 12 complete towers can be linked in parallel for scalable capacity scaling from 7.1 kWh to 255.72 kWh. Equipped with a built-in Wi-Fi antenna and explicit status lights, the BMS flawlessly communicates via CAN / RS485 protocols with major high-voltage inverters.

Installation Requirement:
  • System installation must exclusively be conducted by qualified HV technicians following certified safety regulations.
  • Important Notice: Tower S3 series components must never be mixed or interconnected with legacy Tower (1.5G / T-series) modules or older BMS models.
  • Maintain a minimum clearance space of 100 to 200 mm from the back wall and adjacent electronics to secure sufficient airflow.

Which hybrid inverters are compatible with the Tower S3 BMS?

The Tower S3 platform offers extensive inverter matching, interfacing perfectly via CAN/RS485 with top brands including Solis, GoodWe, Ingeteam, Solplanet, SAJ, DEYE, Hoymiles, and SOLINTEG.

Can I mix or upgrade older Tower T-Series modules into this S3 system?

No, cross-connecting or combining elements from the Tower S3 series with previous Tower 1.5G / T-series hardware is strictly prohibited. The S3 generation works with specialized HV9637S battery modules and distinct BDU configurations.

How many battery modules can be stacked on this BMS & Base combo?

A single tower system can stack a minimum of 2 up to a maximum of 6 HV9637S battery modules (rated at 3.552 kWh per pack). This builds up the specific commercial system layouts spanning from TS7 (2 modules) to TS21 (6 modules).
