Dyness STACK280 battery module 14.34 kWh / 51.2 V / 280 Ah

Overview

The Dyness STACK280 (model S51280) is a high-voltage stackable LiFePO4 battery module designed for residential and small commercial energy storage. Each module delivers 14.34 kWh nominal energy (13.62 kWh usable) at 51.2 V / 280 Ah. Modules connect via blind-mate composite connectors with no cables between modules, allowing 3 to 15 modules to be stacked into a single cluster for 43 to 215 kWh of capacity.

Key Features

• Plug-and-play stacking: rackless design, modules stack onto the SBDU with composite blind-mate connectors. No inter-module wiring.
• Built-in aerosol fire extinguisher in every module, suppression in approximately 5 seconds.
• LiFePO4 chemistry, 8000+ cycle life at 95% DOD, 10-year warranty.
• 200 A continuous, 280 A peak (2 min) charge/discharge per cluster.
• Forced air cooling with built-in air duct between modules.
• Module mixing tolerated within 3 years of production date.
• Self-discharge low: up to 10-12 months in storage without charging.

Technical specifications
