As Europe accelerates its energy transition, distributed photovoltaics, battery storage, electric vehicles, and intelligent energy management are becoming increasingly interconnected. Germany, in particular, is driving this transformation through dynamic electricity pricing, expanding electrification, and stronger grid-interaction policies, creating growing demand for energy systems that are not only efficient, but also intelligent, reliable, and fully integrated.
Against this backdrop, Sieyuan Group and Swatten made a strong appearance at Intersolar Europe 2026, showcasing a complete "From Grid to Home" energy ecosystem that extends utility-grade engineering from national power grids into homes and businesses.
Unlike conventional exhibitors focused on individual products, Sieyuan demonstrated a fully integrated power value chain covering power transformers, GIS, medium-voltage switchgear, low-voltage switchgear, the esGrid 3.0 utility-scale BESS, and Swatten residential & C&I energy storage solutions. Together, these technologies illustrated one of the industry's rarest capabilities—delivering a seamless energy chain from generation, transmission, substation, distribution, and utility-scale storage to end-user energy consumption.
Backed by more than three decades of power engineering experience, Swatten carries forward Sieyuan's grid engineering DNA into residential energy storage. Swatten's philosophy is equally straightforward:"We build grid gear to build home gear."
Rather than adapting consumer electronics into energy products, Swatten applies utility-grade engineering standards to every residential energy solution, bringing grid-level safety, reliability, and intelligent power management directly into everyday homes.
One of the highlights at Intersolar Europe was the Swatten Real All-in-One System. Unlike many conventional "all-in-one" solutions that still require an additional EV charging module or external energy management components, Swatten integrates the hybrid inverter, battery system, intelligent EMS, BMS, and AC EV charger into one factory-engineered platform.
There is no need to install extra charging box out of the stackable or extend additional charging module in the existing stackable. Swatten All-in-one contains built-in charger without any other purchase or any installation or extention. The end user can DIY a plug-play charging handle anytime without any installer help. It will save charger cost and installation fee and time.
Supporting direct solar-to-EV charging, intelligent Time-of-Use (TOU) optimization, peak shaving, backup power, and future Virtual Power Plant (VPP) connectivity, the system enables homeowners to manage solar generation, battery storage, household loads, and electric mobility through one unified energy platform. A true All-in-One is designed as one system—not assembled from multiple boxes.
Swatten also introduced its latest 5.12 kWh modular stackable battery, designed specifically for premium European households. Each module delivers flexible capacity expansion while incorporating a comprehensive four-layer protection architecture, including thermal insulation buffering (MPP) to limit heat transfer, electrical insulation (PC sheets) to prevent propagation, high-temperature mica protection capable of withstanding up to 800°C, and an integrated aerosol fire-suppression system for early-stage intervention. By bringing utility-grade safety technologies into residential applications, Swatten extends the reliability standards traditionally reserved for national power infrastructure to every household.
As Europe's electricity system becomes increasingly decentralized, the future of energy lies not only in smarter products, but in stronger system integration.
At Intersolar Europe 2026, Sieyuan and Swatten demonstrated that "From Grid to Home" is more than a brand slogan. It is a complete engineering philosophy that transforms decades of grid expertise into safer, smarter, and more sustainable energy solutions—connecting national grids with every home and every business across Europe.
