The journey of electricity—from generation, transmission, transformation, and distribution to end-use—is a finely tuned relay race. Sieyuan Electric (Stock Code: 002028.SZ) has been a trusted runner in this relay race for over 32 years, delivering high-voltage equipment (10kV–1000kV) and engineering solutions to more than 100 countries. In the UK, Sieyuan has worked with major clients such as National Grid, SSE, ILOS, and HVSS for over a decade, supplying instrument transformers, power transformers, circuit breakers and shunt reactors to ensure safe, stable, and efficient electricity for businesses and households nationwide.
Swatten Solutions: Utility-Grade Reliability and Flexibility for the UK Energy Future
Extending this expertise to the end-user, Swatten defines residential BESS as a professional-grade household electric equipment rather than a simple white appliance. At Solar & Storage Live in Birmingham, Swatten showcased how its systems go far beyond traditional storage by providing a highly flexible and safe energy ecosystem that integrates solar PV, batteries, EV chargers, and SG-ready heat pumps. For households and businesses, this means lower energy bills, greater independence from volatile tariffs, and a seamless shift to green mobility and heating.
Swatten’s 10–50kW three-phase hybrid inverter, supporting up to 30 units in parallel (1.5MW output, 3MWh storage) and 1.8MW PV integration, making it ideal for factories, farms, commercial buildings, and advanced home applications. Key features include a 16A PV input current, 20A short-circuit current, wide compatibility with most panels, and a 3-MPPT, 6-string design supporting 200% oversizing for higher energy efficiency and multi-orientation installations. Its 150V ultra-low start-up voltage and 150–950V MPPT range enable earlier start-up, longer generation, and reliable output under the UK’s weak sunlight. A true highlight is its powerful 55kW on-grid bypass output, perfectly tailored for the UK’s Future Homes Standard (FHS), which mandates the integration of solar, storage, EV charging, and heat pumps in new homes from 2025. With this capability, the system ensures that an 11kW EV charger and high-demand appliances such as heat pumps can run simultaneously—delivering not only whole-home backup but also seamless support for the UK’s transition toward greener mobility, heating, and household energy independence.
Installer-Friendly, User-Centric Design
Swatten’s entire product line is built on the principle of “benefiting both installers and end-users”. With lightweight, high-density, and modular designs, the brand not only reflects Sieyuan Electric’s utility-grade engineering strength but also optimises every stage of installation and daily use. In the UK, where single-phase systems dominate the residential market, Swatten’s 3–6kW inverters weigh less than 20kg and require no additional distribution boxes—enabling easy, single-person installation while reducing labour intensity. For households, the 50V ultra-low start-up voltage ensures earlier power generation each morning and extended operation into the evening. Even under cloudy skies or weak light, the system maintains stable performance, securing an uninterrupted home electricity supply. Meanwhile, with up to 330% DC oversizing, Swatten allows more solar modules to be connected, injecting households with greater volumes of clean, renewable energy.
From Consumers to Prosumers
Beyond reliability and convenience, Swatten empowers users to actively participate in the energy market. Its solutions are VPP-ready, enabling households to feed excess solar back to the grid, respond to dynamic tariffs, and provide aggregated flexibility services. This transforms users from passive consumers into prosumers—saving money while earning new income and supporting grid stability.
With Swatten powered by Sieyuan, the same utility-grade reliability trusted by national grids is now available at the user side. From grid to home, Swatten delivers flexible, future-ready solutions that combine professional engineering with real-world savings—helping the UK accelerate its clean energy transition.
