Dyness 5.12kWh High-Voltage Lithium Battery (Tower/Stack Series)

Product Overview

The Dyness HV 5.12kWh module (often referred to under the Tower or Stack100 series) is a premium energy storage solution designed for high-demand residential and commercial applications. Available at Powernest Limited, these high-voltage modules are engineered to be connected in series to reach the high DC voltages (up to 800V+) required by industrial-grade three-phase hybrid inverters. By operating at a higher voltage, the system reduces current flow and heat generation, resulting in industry-leading efficiency and simplified wiring for large-scale energy projects.

Key Features

• Industrial High-Voltage Design: Unlike standard 48V batteries, these modules connect in series within a “Tower” or “Stack,” allowing the system to match the high-voltage input requirements of large commercial inverters for maximum round-trip efficiency.

• Exceptional Cycle Life: Rated for over 6,000 cycles at 80% to 90% Depth of Discharge (DoD), providing a reliable service life of 15+ years in high-cycling environments.

• Vertical Stackability: Features a “plug-and-play” stackable design. Modules are stacked vertically without the need for external battery cables between them, creating a clean, space-saving, and professional-looking installation.

• Safe LFP Chemistry: Built using Lithium Iron Phosphate (LiFePO4) technology, which offers the highest thermal stability and safety profile of any lithium-ion chemistry.

• Flexible Scalability: Start with a minimum cluster (typically 3 modules) and expand up to 15 modules in a single stack, providing up to 76.8kWh of storage. For megawatt-scale needs, multiple stacks can be paralleled.

• Intelligent HV Management: Controlled by a dedicated High-Voltage BDU (Battery Distribution Unit) that manages cell balancing, SOC (State of Charge) calibration, and multi-layered safety protections for the entire string.
