STUTTGART, Germany, Sept. 19, 2026 /CourierPR/ -- At Sigenergy Day Europe 2026, Sigenergy outlined its next phase of growth beyond residential energy storage into commercial and industrial (C&I) and utility-scale applications. The event, which brought together nearly 400 investors, EPC companies, industry experts, distributors, and partners, focused on project delivery, system safety, and the commercial value of storage.
One of the key projects highlighted was the 20 MWh Weissach im Tal project in Baden-Württemberg. This project combines 11.6 MWp of solar generation with approximately 20 MWh of battery storage. Owned by DGS GmbH, the project was developed by solar specialist Arausol and supported by European distributor Memodo. It entered commercial operation in early August 2026.
The system at Weissach im Tal comprises 1,660 Sigenergy battery modules, each rated at 12 kWh, and 80 Sigen C&I PV inverters, each rated at 100 kW. Two medium-voltage transformer stations with pre-installed low-voltage connections were also part of the setup. The project utilizes a decentralized SigenStack architecture, which Sigenergy describes as its modular battery energy storage system (BESS) solution for commercial applications.
Installation of the system was completed in just 20 days, followed by a two-hour commissioning process. Unlike conventional container-based storage, the modular units were installed beneath the PV mounting structures and close to the PV strings. This arrangement minimized the need for additional land, complex cabling, heavy equipment, and extensive foundations. By integrating Sigenergy inverters, transformers, and system management, the project reduced multi-vendor coordination.
The decentralized architecture also allowed for DC coupling, keeping the PV-to-battery energy path on the DC side. This avoided an intermediate AC conversion and eliminated the need for dedicated battery transformers, driving a 3%, 4% uplift in overall energy yield.
Sigenergy’s portfolio now addresses different project architectures and scales, from modular, decentralized SigenStack deployments to centralized C&I and utility-scale applications. The upcoming SigenCube provides an integrated option for centralized C&I applications, while SigenTerra extends the portfolio to large-scale storage and solar-plus-storage projects.
Founded in 2022 and headquartered in Shanghai, Sigenergy Technology Co., Ltd. (HKEX: 6656) is a technology company focused on renewable energy solutions. Its business spans photovoltaic generation, energy storage, and electric vehicle charging for residential, commercial, industrial, and utility-scale applications. Guided by its “AI in All” strategy, Sigenergy integrates artificial intelligence across its products and energy management systems to support safer, smarter, and more efficient energy use.
The announcement of the Weissach im Tal project and Sigenergy’s broader strategy underscores the company’s commitment to expanding its presence in the European market. The project and the company’s detailed approach to storage solutions demonstrate a clear path to meeting the growing demand for sustainable and efficient energy storage systems.
