As the global energy transition accelerates, the demand for smarter, safer, and more reliable power solutions has never been more urgent. Swatten, an energy storage brand incubated by Sieyuan Electric (Stock Code: 002028.SZ), is bringing utility-grade engineering into residential and commercial energy storage markets—redefining industry expectations around reliability, safety, and professionalism. Backed by more than 30 years of power system engineering experience, Swatten delivers solutions built to operate with the durability and stability of grid infrastructure.

Since the 1990s, Sieyuan Electric has supplied 10kV to 1000kV high-voltage electrical equipment to more than 100 countries. Its client base includes major grid operators such as SGCC (China), National Grid UK, ENEL, REE, and CFE. Swatten builds on this strong technical legacy to serve the evolving energy needs of modern households and enterprises.

Built on decades of expertise in power systems, Swatten approaches energy storage as an ultimate electric equipment, not a home appliance. This foundation informs every aspect of its product design—balancing grid-level engineering with real-world application needs. Every Swatten product adheres to seven core design principles: universal compatibility, integrated on/off-grid functionality, battery-ready configuration, fanless silent operation (<35 dB), maximized DC input, maximized off-grid output, and easy installation with minimal maintenance. These features reflect not only Swatten’s system-level engineering but also its attention to user experience and real-world deployment.

The brand’s design approach is focused on reducing installation complexity and minimizing long-term maintenance. Lightweight, modular hardware significantly reduces the physical strain of equipment handling—helping to protect installers from long-term musculoskeletal injuries. For example, the single-phase hybrid inverter (6kW) weighs just 20kg and can be installed by one person. This installer-oriented thinking enhances job site efficiency while acknowledging the health and well-being of frontline technicians.

The fanless thermal design increases long-term system reliability, eliminates dust accumulation, and reduces acoustic disturbances—all while ensuring a healthier and quieter living environment for end users. All Swatten systems include integrated backup power functionality, enabling whole-home or full-facility load coverage. During grid outages, systems automatically isolate from the grid and maintain secure off-grid operation.

Swatten positions its solutions not as home appliances, but as professional-grade electric equipment—delivering the same level of engineering excellence trusted by utility professionals. As the company puts it: "Do you know the substation in your neighborhood is powered by high-voltage equipment we built? Now it’s time to make the same professional choice at home."

Swatten is actively expanding across Europe, Australia, and Asia through regional compliance adaptation and localized service networks. From Italian villas to Australian farms and remote industrial sites, the company is enabling smarter, quieter, and more dependable energy access—illuminating the Path to Global Energy Freedom.
