Dyness STACK100 High Voltage LiFePO₄ Battery Energy Storage System

The Dyness STACK100 is a modular, rackless and stackable LiFePO₄ battery energy storage system designed for residential, small commercial and industrial energy storage applications. Its plug-and-play architecture allows flexible system expansion, with up to 12 clusters connected in parallel and a maximum stated system capacity of 921 kWh.

With support for 1C charge and discharge, high depth of discharge and a stated cycle life of ≥8,000 cycles / 10 years, STACK100 is designed for applications requiring flexible and reliable energy storage.

Key Features

Modular & Scalable Energy Storage

STACK100 uses a modular architecture that makes it easy to expand the storage system according to your energy requirements. The manufacturer specifies a system energy range of 15.36–76.8 kWh per cluster, with up to 12 clusters operating in parallel.

This provides a scalable architecture for applications requiring increased battery capacity over time.

High-Performance LiFePO₄ Battery

The STACK100 uses LiFePO₄ battery technology, with each battery module rated at 51.2V / 100Ah and weighing approximately 47 kg.

1C Charge & Discharge

The system supports a recommended charge/discharge current of 50A (0.5C) and a maximum charge/discharge current of 100A (1C). Peak discharge current is specified at 125A for 2 minutes at 25°C.

This makes STACK100 suitable for applications requiring high-power battery operation, including grid frequency regulation and charging-station applications.

Long Cycle Life

Dyness specifies a cycle life of:

≥8,000 cycles / 10 years

The datasheet states that testing is based on 0.2C charging and discharging at 25°C and 95% DOD.

High Depth of Discharge

STACK100 has a specified 95% depth of discharge (DOD), allowing a large portion of the installed battery capacity to be utilized.

Integrated Safety Features

The battery incorporates an aerosol fire extinguishing system and has an IP20 protection level.

The manufacturer describes an intelligent fire-extinguishing system capable of detecting and extinguishing fire within 5 seconds.

Easy Stack-Type Installation

STACK100 uses a rackless stack-type installation designed to simplify installation. The manufacturer describes the system as requiring zero wiring between stacked modules and states that one cluster can be installed in approximately 30 minutes.

Automatic Self-Heating Option

An optional automatic self-heating function is available, with the specified charging temperature range extending from -20°C to 55°C when the option is fitted. The standard charging temperature range is 0°C to 55°C, while the discharging temperature range is -20°C to 55°C.

Battery Equalization

STACK100 supports battery-module mixing within three years according to the manufacturer’s product information, providing additional flexibility when expanding or configuring the system.
