Dyness Tower TS17 – 17.76 kWh HV Home Battery (LiFePO4)
Couldn't load pickup availability
The Dyness Tower TS17 is the second-largest variant of the Dyness Tower S3 high-voltage (HV) energy storage system and offers a nominal capacity of 17.76 kWh at a nominal voltage of 480V DC. The system consists of five HV9637S LiFePO4 battery modules and a Tower S3 BMS & Base Unit as the central management unit. With a usable capacity of 16.872 kWh at 95% DOD and a maximum continuous charge/discharge power of 10.65 kW, the Tower TS17 is suitable for residential energy storage with a high power profile, in combination with a compatible HV hybrid inverter. The system is modularly expandable to a maximum of 255.72 kWh via parallel connection of up to 12 complete towers.

- Installation must be carried out exclusively by qualified HV installers in accordance with applicable safety regulations.
- Tower S3 and Tower T-series must not be mixed: Tower S3 components (HV9637S modules and S3 BMS) are not compatible with the older Tower T-series (1.5G, HV9637 modules). Combining or connecting both series in parallel will result in system malfunctions and loss of warranty.
- Maintain a minimum ventilation clearance of 100 to 200 mm from the back wall and adjacent equipment during installation.
What is included in the package?
The Tower TS17 is supplied as a complete system consisting of:
- 5x Dyness Tower S3 battery module HV9637S (3.55 kWh per module)
- 1x Dyness Tower S3 SBDU (BMS controller with DC breaker, WAKE button and integrated Wi-Fi)
- 1x Dyness Tower S3 Base (baseboard with adjustable levelling feet)
- 1x Red DC power cable (positive, 2m)
- 1x Black DC power cable (negative, 2m)
- 1x Inverter communication cable (RJ45, 2m)
- 1x RJ45-CAN-120 Ohm termination resistor
- Assembly hardware (screws and OT4-6 grounding terminals) and user manual
The BMS & Base Unit and battery modules are also available separately for expanding an existing Tower S3 system.
Which inverters are compatible with the Dyness Tower TS17?
The Tower S3 series communicates via CAN/RS485 with a wide range of leading HV inverters, including Solis, GoodWe, Ingeteam, Solplanet, SAJ, DEYE, Hoymiles, SOLINTEG and Kaco. Please consult the user manual or contact us for the most up-to-date compatibility list and the required firmware settings per inverter model.
Can I mix Tower S3 components with the older Tower T-series?
No. Connecting or mixing Tower S3 components with the older Tower T-series (1.5G) is strictly prohibited. The Tower S3 series uses HV9637S battery modules and a fully redesigned BDU topology that is not compatible with the Tower T-series (HV9637 modules). Combining both series will result in system malfunctions and loss of warranty. Please refer to the comparison sheet for a full overview of the differences between both series.
Can I expand the Tower TS17 to the maximum capacity at a later stage?
Yes. The Tower TS17 is expandable to the maximum single-tower configuration TS21 (21.31 kWh) by adding one further HV9637S battery module. For larger projects, up to 12 complete towers can be connected in parallel for a maximum system capacity of 255.72 kWh. Always verify the maximum configuration of the connected inverter before expanding.
Why does the Dyness Tower TS17 become more attractive as solar export rates decline?
As solar feed-in tariffs continue to decline across Europe and time-of-use energy pricing becomes more widespread, storing self-generated solar energy locally is becoming increasingly financially relevant. The Dyness Tower TS17 enables you to use solar energy generated during the day in the evening and at night, reducing low-value grid exports and maximising self-consumption at the full retail electricity price. With a usable capacity of 16.872 kWh and a continuous power of 10.65 kW, the Tower TS17 is particularly well suited for homes with a heat pump, electric vehicle or high daily consumption, where sufficient capacity must remain available throughout the night. The actual financial benefit depends on your consumption profile, PV yield, energy contract and applicable feed-in tariffs.
