Dyness is discontinuing the original Tower (T7–T21) series and replacing it with a new generation of high-voltage storage. The direct successor for homes is Tower Pro; for scalable and commercial installations there are Stack100 and Stack280.
Why Tower Pro instead of Tower?
Same-class comparison (288 V, 3 modules): Tower T10 vs. Tower Pro TP11. Figures from official Dyness datasheets.
| Dyness Tower T10 | Dyness Tower Pro TP11 | |
|---|---|---|
| Nominal energy (tower) | 10,66 kWh | 11,52 kWh |
| Battery module | HV9637 · 3,55 kWh (37 Ah) | HV9640 · 3,84 kWh (40 Ah) |
| Continuous power (chg./dis.) | 6,39 kW (0,6C) | 11,52 kW (1C) ★ |
| Cycle life | ≥6000 | ≥8000 ★ |
| Protection (IP) | IP54 | IP55 |
| In-module fire suppression | none | Built-in aerosol (<5 s) |
| Module self-heating | none | Automatic, to −20 °C (optional) |
| Free module mixing | – | Yes, within 3 years |
| Depth of discharge (DoD) | 95 % | 95 % |
| Max. per tower / parallel | 21,31 kWh / 12 | 23,04 kWh / 12 (276,48 kWh) |
* Not listed in the Tower series specification. Both systems: LiFePO4, cable-free stacking, CAN/RS485 communication.
What this means for you
In plain terms: Tower Pro stores the same kind of energy as before, but it can release it faster and lasts longer. For most homes that means it can run more appliances at once, cope better with a heat pump or backup, and serve you for several more years.
- Almost 2× power: At the same capacity Tower Pro delivers 1C instead of 0.6C – ideal for heat pumps, cooktops, EV charging and backup power.
- Longer life: ≥8000 cycles vs. ≥6000 on the original Tower – about a third longer life at 95 % DoD.
- Higher safety: Built-in aerosol fire suppression activating within 5 s and module self-heating down to −20 °C.
- More flexibility: Up to 12 towers in parallel (7.68–276.48 kWh) and free module mixing within 3 years.
Which successor to choose?
Three new-generation lines by project type. All LiFePO4, high-voltage, with cable-free stacking and aerosol fire suppression.
- Tower Pro (TP7–TP23): 7,68–23,04 kWh. Homes, backup power, heat pumps. Direct Tower successor. IP55.
- Stack100: 15,36–76,8 kWh / tower. Homes and smaller commercial installs needing fine 5.12 kWh scaling. IP20 (indoor).
- Stack280: 43 kWh – 2,58 MWh. Commercial and industrial projects, high-capacity and container storage. IP20.

Frequently asked questions
Is the Dyness Tower being discontinued?
Yes. The original Tower (T7–T21) series is being phased out and sold while stocks last. Tower Pro is the direct successor.
What is the difference between Tower and Tower Pro?
Tower Pro delivers almost double the continuous power (1C vs 0.6C), lasts longer (≥8000 vs ≥6000 cycles), and adds built-in fire suppression, self-heating and IP55 protection. Installation stays just as easy with cable-free stacking.
Can I add Tower Pro modules to my existing Tower?
No. Tower (HV9637) and Tower Pro (HV9640) modules can't be mixed in one tower. Expand an existing Tower with Tower modules while they last, or add a new Tower Pro tower.
How much capacity do I need, and what about a heat pump?
A typical home is fine with 7–11 kWh. A home with a heat pump, higher use or backup benefits from 11–19 kWh and especially Tower Pro's 1C power, which runs demanding appliances with ease.
Is Tower Pro compatible with my inverter?
Tower Pro works with GoodWe, Solis, Solinteg, Deye and many more. Always confirm your exact model and firmware before installing.
Are the batteries safe, and can they go outside?
Yes. They use safe LiFePO4 chemistry with built-in aerosol fire suppression. Tower Pro is IP55 (indoor or sheltered outdoor); Stack100 and Stack280 are IP20 (indoor).
