Dyness Battery Lithium S51314 HV (Stackable)
ETA 2-3 Working Days
The Dyness STACK314 is a high-performance, modular lithium iron phosphate (LiFePO₄) battery energy storage solution designed for commercial and industrial applications. Offering 16.08 kWh per battery module and scalable system capacity up to 241.14 kWh per stack, the STACK314 delivers reliable, safe, and flexible energy storage for solar installations, backup power systems, and energy management projects.
Its innovative cable-free stacking design enables rapid installation and seamless expansion, while support for up to 12 clusters in parallel allows systems to scale to 2.89 MWh of storage capacity. The integrated aerosol fire suppression system provides enhanced safety, and the long-life LiFePO₄ chemistry offers over 8,000 charge cycles for dependable long-term performance.
Built to operate in demanding environments, the STACK314 features a wide operating temperature range and supports a maximum continuous charge/discharge current of 200A, making it ideal for applications requiring high power availability and energy reliability.
BDU200 Required for System Operation
- System Requirement: Each STACK314 system requires one Dyness S51314 BDU200 (Battery Distribution Unit), which serves as the central HV controller, protection hub, and inverter communication interface for all connected modules. The BDU200 is sold separately — confirm your full system design and HV inverter compatibility with a qualified installer before ordering.
