Description
Dyness STACK100 5.12kWh 51.2V LiFePO₄ High-Voltage Lithium Battery Module
The Dyness STACK100 is a high-voltage LiFePO₄ lithium battery module designed for projects that need dependable storage and room to grow. With 5.12kWh nominal capacity, 51.2V nominal voltage, and 100Ah capacity, it gives you a strong building block for modern solar and backup power systems.
What makes the STACK100 especially attractive is its expandability. A single cluster can be built from 3 to 15 modules, and the system can scale further up to 12 clusters in parallel, reaching a total of 921.6kWh. That makes it suitable not only for larger homes, but also for offices, apartments, schools, shops, and other commercial installations where energy demand may grow over time.
Its cable-free stackable design helps keep installation work cleaner and more organised, while CAN and RS485 communication support easier integration with compatible inverter systems. The battery also supports 1C charge and discharge, giving it the performance needed for real operating conditions rather than just light-duty storage.
The use of LiFePO₄ battery chemistry means better safety, stable performance, and long life. With 95% depth of discharge, 8000+ cycles, and a 10-year warranty, the Dyness STACK100 is built for clients who want a serious storage solution that can serve reliably for years.
