High-voltage Dyness Tower Pro (HV9640) battery module with LiFePO4 cells, 3.84 kWh energy, and 96 V nominal voltage. Used in the scalable, modular Tower Pro energy storage system.
Dyness ES-Dyness-PRO-HV-9640-3.84-EU is a high-voltage battery module from the Tower Pro series, built with lithium iron phosphate (LiFePO4) cells. A single HV9640 module provides 3.84 kWh of energy at a nominal voltage of 96 V and a capacity of 40 Ah. The Tower Pro stack can be expanded from 2 to 6 modules (7.68–23.04 kWh), and up to 12 stacks can be connected in parallel, achieving a maximum capacity of 276.48 kWh. The modular, stackable design with automatic configuration and wireless connection facilitates installation and maintenance. The system supports 1C fast charging and discharging and is suitable for indoor and outdoor installations thanks to its IP55 protection rating.
