The Dyness Stack100 PRO Extension Pack is the add-on battery module used to increase the capacity of a Dyness Stack100 Pro storage system. Built with LiFePO4 (LFP) battery technology, it offers a strong combination of safety, cycle life, and modular flexibility for residential and light commercial energy storage projects. According to the datasheet, each module provides 5.12kWh nominal battery energy, 4.864kWh usable energy, 51.2V nominal voltage, and 100Ah nominal capacity.
As part of the Stack100 Pro platform, the Extension Pack is designed for cable-free stacking, helping speed up installation and keep the system layout clean and compact. Dyness states that each cluster can be built with 3 to 15 modules, delivering a total energy range of 15.36kWh to 76.8kWh per cluster. The product overview on page 1 also highlights that the wider system supports up to 12 clusters in parallel, making it suitable for projects that may need future capacity expansion.
The module supports a recommended charge/discharge rate of 0.5C (50A) and a maximum charge/discharge rate of 1C (100A), with 95% depth of discharge and a stated cycle life of at least 8000 cycles under the listed test conditions. It also benefits from IP66 protection, natural cooling for quiet operation, and CAN/RS485 communication within the Stack100 Pro platform. Compatible inverter brands listed in the datasheet include Solis, GoodWe, Growatt, Deye, and Solinteg.
The datasheet lists the module dimensions as 657 × 460 × 193 mm with a weight of 23.5kg, making the Dyness Stack100 PRO Extension Pack a practical building block for scalable high-voltage battery storage systems.
