Sigenergy Hosts Sigenergy Day Europe 2026 Highlighting AI and Modular Storage Solutions

STUTTGART, Germany, Sept. 10, 2026 /CourierPR/ -- Sigenergy, a leading provider of battery energy storage solutions, hosted Sigenergy Day Europe 2026 in Stuttgart, Germany, gathering nearly 400 global investors, engineering project companies (EPCs), and industry experts to explore the future of utility-scale energy storage. The event centered on how artificial intelligence (AI), modular storage, and direct current (DC) coupling can enhance renewable energy economics.

One of the key highlights of the event was a visit to the Weissach im Tal project, a 11.6 MWp photovoltaic (PV) and 20 MWh battery energy storage system owned by Deutsche Gesellschaft für Sachwertanlagen (DGS) GmbH. This project, developed by PV specialist Arausol and supported by European distributor Memodo, utilized 1,660 Sigenergy battery modules, each with a 12-kilowatt-hour (kWh) capacity, and 80 units of Sigen C&I PV inverters with a capacity of 100 kW. The project also featured two medium-voltage transformer (MVT) stations equipped with pre-installed low-voltage connections.

Unlike traditional containerized systems, the decentralized SigenStack architecture allowed for installation close to PV strings, significantly reducing complex cabling, heavy equipment, and extensive foundations. The project was completed in just 20 days and commissioned in two hours, showcasing the potential of modular storage to accelerate the delivery of utility-scale projects.

During the event, Sigenergy founder and CEO Tony Xu emphasized the company's strategic expansion from residential storage into commercial, industrial (C&I), and utility-scale power plants. He stated, "Sigenergy is fully prepared for this next phase of growth. Backed by a robust European team and a comprehensive product lineup, including SigenStack, SigenCube, and SigenTerra, we aim to evolve from a standard supplier into a long-term strategic partner in the transition to storage."

Jaime Arau, founder and managing director of Arausol, highlighted Sigenergy's innovative and problem-solving capabilities, which will help accelerate large-scale solar-plus-storage deployment across Europe. He said, "Partnerships like ours between Arausol and Sigenergy are characterized by tackling challenges together and turning them into opportunities. Today is intended to help us further develop this shared journey."

During the event, Bernhard Rill, member of the board of trustees at the Energy Storage System Association (BVES), underscored the critical role of flexible energy infrastructure in driving Europe's renewable energy goals. Rill noted that co-located solar-plus-storage and stand-alone battery energy storage systems (BESS) have become standard requirements for grid resilience. He cited SigenStack's 6-layer safety architecture, which detects and suppresses thermal runaway in seconds, as a key feature for modern deployments.

Sigenergy's utility-scale solar and energy storage solutions completed key technical assessments this year, and the company's utility solar inverter underwent a technical review by DNV, resulting in the issuance of the Sigen Utility Solar Inverter Technology Review Report.

Julian A. Crestani, project lead at DGS, received the prestigious "Iconic Project of the Year 2026" award for the Weissach im Tal deployment, a testament to exceptional engineering, operational efficiency, and rapid execution powered by Sigenergy's advanced solar-plus-storage architecture.

The event explored the economic value of intelligent storage, with Christoph Gardlo, COO of ESFORIN SE, emphasizing that the future of energy flexibility relies on co-located assets. He noted that rising price volatility creates unprecedented profit opportunities for integrated solar-and-battery projects. By deploying ESFORIN's AI-driven FLEXtrading platform to automate asset management and execute real-time power trades, co-located PV-BESS installations can yield up to three times more revenue than standalone solar plants.

Sigenergy's Co-Founder, Roy Zhang, delivered an inspiring call to action, outlining how continuous AI innovation, deep technical expertise, and enduring long-term partnerships will define Europe's clean energy future. He stated, "Backed by over €170 million in R&D investment, 900+ engineers, and 1,000+ patents, Sigenergy stands fully committed to powering this transition. From the innovative SigenStack system and the upcoming SigenCube C&I system to SigenTerra utility solutions and SigenAgent, the industry's first full-domain AI agent, Sigenergy delivers an end-to-end, full-scenario portfolio designed to lead the market."

Björn Lamprecht and Henning Wicht, managing directors at Arausol, shared insights into Arausol’s approach and role in the project, highlighting the Weissach im Tal deployment's three standout advantages: superior system efficiency, optimized land-use efficiency, and seamless end-to-end infrastructure and project delivery.

By pairing decentralized storage with intelligent optimization, Sigenergy has demonstrated how to maximize yield while stripping away deployment complexity. The company remains relentless in putting customers and partners at the heart of innovation, uniting hardware precision with digital intelligence, and accelerating the deployment of next-generation energy infrastructure across Europe and around the globe.
