Dyness Stack100 Battery S51100

The Dyness Stackable 100 Battery S51100 is a high-voltage lithium iron phosphate (LiFePO4) energy storage solution designed for residential, commercial, and small industrial solar and backup applications. Built for scalability, safety, and long-term performance, this modular battery system delivers reliable energy storage for grid-tied, hybrid, and off-grid systems commonly used in South Africa.

High-Performance Modular Energy Storage

Each S51100 battery module operates at 51.2V / 100Ah and forms part of the Dyness STACK100 system, allowing flexible system configurations from 15.36kWh up to 76.8kWh per cluster, with support for up to 12 clusters in parallel, enabling maximum system capacities of up to 921kWh. This makes it suitable for everything from residential backup to commercial load shifting and grid support.

The system supports 1C charge and discharge, ensuring fast energy response during peak demand, load shedding, or grid instability.

Long Service Life and Proven Safety

The Dyness S51100 uses LiFePO4 (LFP) cell chemistry, known for its superior thermal stability, inherent safety, and long lifespan. With a design life of 6,000+ cycles at 95% depth of discharge, it delivers dependable performance over many years.

Integrated safety features include:

• Intelligent Battery Management System (BMS)
• Built-in aerosol fire extinguishing system
• Multiple layers of electrical and thermal protection

These features make the system suitable for both indoor and controlled technical installation environments.

Stackable, Rackless, Plug-and-Play Design

The rackless, stack-type design allows for quick installation without complex mounting hardware. Modules stack directly on top of each other, reducing installation time and space requirements. A single cluster can typically be installed in under 30 minutes by qualified installers.

Forced air cooling ensures stable operation across a wide temperature range, enhancing durability in demanding local conditions.

Smart Monitoring and System Integration

The Dyness Stackable 100 Battery includes:

• CAN and RS485 communication
• Built-in WiFi module
• Remote monitoring and OTA firmware updates via mobile app

The system is compatible with a wide range of popular hybrid and commercial inverters, including brands such as Sunsynk, Deye, GoodWe, Growatt, Solis, Solplanet, SAJ, Ingeteam, Hoymiles, and others, subject to model compatibility.
