In the vast journey of electricity — from generation, transmission, transformation, and distribution to final consumption — every kW travels thousands of miles before reaching households and businesses. This process is not a sprint but a carefully coordinated relay race. Sieyuan Electric (Stock Code: 002028.SZ) has been a trusted partner in this “relay of power” for over 32 years, delivering high-voltage equipment (10 kV – 1,000 kV) and engineering solutions to over 100 countries — ensuring electricity flows seamlessly from one stage to the next, all the way to the end-user.
For over 16 years, Sieyuan Electric has been a leader in supporting large-scale energy projects across Australia. With a cumulative capacity of more than 9.9 GW and involvement in over 50 projects about MW level, Sieyuan has established itself as a trusted partner for grid operators, energy companies, and major EPC firms. Key clients include Acciona Energy, AusNet, CitiPower and Powercor, Elecnor, Jemena, and Western Power. This extensive experience positions Swatten to continue delivering world-class energy solutions in Australia.
Now, as electrification and energy transition accelerating, Sieyuan is extending its strategy to the end-user side with Swatten, a dedicated brand for residential and small C&I energy storage. This marks the final link in the company’s holistic vision — “From Grid to Home” — creating a complete power loop from generation to consumption. Swatten brings utility-grade engineering into homes and businesses, redefining expectations of reliability, safety, and professionalism in the energy storage sector.
Rather than making a home appliance, Swatten designs its systems as professional-grade electric equipment. Swatten’s product development is guided by seven core principles: universal compatibility with diverse PV and battery systems, integrated on/off-grid functionality, battery-ready configuration for future upgrades, fanless silent operation (<35 dB) for healthier environments, maximised DC input for higher PV integration, maximised off-grid output for critical loads, and lightweight modular design for easy installation and low maintenance. These principles embody both Sieyuan’s grid-level expertise and a strong focus on installer and user experience.
To further empower users, Swatten delivers eight differentiated application scenarios that cover virtually every scenario: maximising self-consumption, flexible grid-tied expansion, energy arbitrage without PV, pure off-grid resilience for remote areas, AC-coupled retrofitting to existing PV systems, dynamic pricing response for ROI acceleration, battery-parallel scalability, and inverter-parallel expansion up to 1.5 MW output capacity.
From households seeking bill savings to commercial facilities requiring industrial-grade power backup, Swatten ensures optimal performance and adaptability.
These innovations also enable users to move beyond consumption to active participation in energy markets. By feeding solar power back to the grid, responding to dynamic tariffs, and supporting VPP (virtual power plant) platforms, Swatten systems enhance grid stability while creating new economic value for users.
From grid to home, Swatten and Seiyuan continues delivering a complete end-to-end power ecosystem. With professionalism and reliability at the core, we provide safe, efficient, and sustainable energy solutions—enabling households and businesses worldwide to embrace a greener and more resilient future.
