The Dyness STACK280 is a robust, modular high-voltage (HV) LiFePO₄ energy storage solution designed for residential, commercial, and industrial ESS applications where reliability, safety, and scalability are essential. Based on a high-capacity 14.34kWh / 51.2V / 280Ah battery module, STACK280 allows system designers to build flexible storage configurations by combining modules in series to reach the required voltage window—ideal for modern hybrid systems and large-capacity energy storage projects.

Scalable architecture for flexible system sizing

STACK280 uses a practical stack-based modular design that supports a wide range of system sizes. Modules can be combined to form clusters suitable for mid-size and larger ESS installations, and expanded further through parallel cluster configuration—making it a future-proof platform that grows with energy demand.

High usable energy and long service life

Engineered for high real-world capacity and long-term performance, STACK280 delivers high usable energy with a deep discharge capability and long cycle life. This makes it a strong choice for daily cycling applications such as solar self-consumption, peak shaving, backup power, and energy cost optimization.

Strong power delivery for demanding loads

STACK280 is built to handle demanding charge and discharge conditions with stable performance, supporting continuous current operation and strong peak discharge capability—well suited for high-load environments and dynamic energy management.

Advanced safety and monitoring

The system integrates intelligent battery management with multi-level protections, including over-charge, over-discharge, over-current and temperature safeguards, plus cell balancing for stable operation over time. Remote monitoring is supported via integrated communication interfaces, and the system is designed for modern connectivity and streamlined maintenance.

Professional installation and system integration

STACK280 is intended for professional HV ESS installations and supports communication-based integration with a wide selection of hybrid and commercial inverter platforms (depending on protocol and firmware compatibility). It is an excellent building block for scalable storage systems in energy storage rooms, technical areas, and controlled indoor environments.

Installation and physical details

• Module dimensions (W×D×H): 770 × 425 × 230.5 mm

• Module weight: 110 kg

• Protection class: IP20 (intended for controlled environments)
