Dyness STACK280 – Modular HV LiFePO₄ Storage Stack (43–215.04kWh)

3 to 15 battery modules per stack • expandable with multiple clusters up to 2.58MWh

The Dyness STACK280 is a premium, scalable high-voltage (HV) LiFePO₄ energy storage platform built for demanding residential, commercial, and industrial ESS projects. It delivers serious storage capacity in a clean, modular stack design—ideal for modern hybrid systems, peak shaving, backup power, and high-cycle self-consumption applications where safety, reliability, and future expansion matter.

Configurable stack capacity: 43–215.04kWh (3–15 modules)

Design your system exactly to the project requirement:

• Minimum stack: 3 modules → 43.0kWh class

• Maximum stack: 15 modules → 215.04kWh
  This modular approach lets you start smaller and scale later without changing the platform—perfect for phased installations and growing energy needs.

Multi-cluster scalability: up to 2.58MWh total storage

For larger sites and higher energy demands, STACK280 supports multiple clusters. By combining stacks (clusters) in parallel, the total storage capacity can reach up to ~2.58MWh (depending on configuration). This makes STACK280 a strong fit not only for large residential and commercial systems, but also for industrial-scale storage rooms and energy hubs.

Built for performance and daily cycling

STACK280 is engineered for real-world ESS use with strong charge/discharge capability, stable operation under load, and a system architecture designed for high-throughput cycling. Whether the goal is maximizing PV self-consumption, reducing demand peaks, or providing reliable backup power—STACK280 is designed to deliver consistent results.

Safety-first HV architecture

Safety is central to the STACK280 design:

• LiFePO₄ chemistry for high thermal stability

• Intelligent BMS protections (over/under voltage, over-current, temperature, fault handling)

• Cell balancing for long-term stability and consistent performance

• System-level design focused on controlled operation and dependable uptime

Monitoring, connectivity, and integration

STACK280 supports modern ESS connectivity and streamlined commissioning:

• CAN / RS485 communication for inverter/EMS integration

• Monitoring-ready system design for operational visibility and service efficiency

• Built for professional integration with a wide range of compatible hybrid and commercial inverter platforms (protocol/firmware dependent)

Installation-friendly modular design

The stack-based platform simplifies logistics, installation, and maintenance:

• Clean system build-up with scalable module count

• Practical stack layout for technical rooms and controlled indoor environments

• Service-friendly structure for future expansion and module-level access

Important note: Dyness STACK280 is a high-voltage DC energy storage system and must be installed and commissioned by qualified professionals, in accordance with local regulations and applicable electrical standards.
