On March 13, 2026, Sigenergy celebrated a landmark moment as its Nantong Smart Energy Center officially launched in Nantong, Jiangsu Province. The event drew nearly 2,000 guests from more than 50 countries and regions, including government representatives, global partners, and industry leaders. A remarkable number of renowned overseas distributors and top-tier installers—many represented by founders, CEOs, and core executives—joined in person, underscoring Sigenergy’s accelerating global influence and the strong confidence that customers and partners worldwide place in Sigenergy’s innovation, intelligent manufacturing, and full-scenario product portfolio.
For Sigenergy, this was more than a launch ceremony. It was a vivid statement of momentum: global collaboration, market validation, and a shared conviction that the next stage of the energy transition will be defined not just by clean power, but by intelligent systems that are easier to deploy, safer to operate, and smarter to optimize.
A Manufacturing Milestone: Turning Innovation into Scaled Global Delivery
Located in the Suxitong Science & Technology Industrial Park, the Nantong Smart Energy Center represents a major step forward in Sigenergy’s global manufacturing strategy. With a total investment of RMB 500 million and a total construction area of approximately 136,000 square meters, the facility is designed to convert Sigenergy’s technology leadership into advanced manufacturing capability, scaled delivery, and stronger global service capacity.
Upon full ramp-up, the Center will enable annual production capacity of more than 300,000 units, covering core products such as inverters and energy storage PACKs. For a company expanding rapidly across global markets, this capacity is not merely “more output”—it is the foundation for reliable global delivery at scale, supporting faster product iteration, stable supply, and consistent quality.
Beyond Automation: From “Single-Point” to Full-Line Intelligent Collaboration
What truly sets the Nantong Smart Energy Center apart is not simply the presence of automation, but the upgrade in manufacturing logic—from “single-point automation” to AI-in-All collaboration.
Powered by an intelligent manufacturing management system, the Center links manufacturing, assembly, testing, and logistics into a unified workflow, achieving equipment linkage, system collaboration, and end-to-end data connectivity. The value of automation here is not only “faster,” but “more consistent”: fewer manual interventions, more stable process execution, and tighter coordination across every key step.
The results are striking. The facility reaches an overall automation rate of 95%, enabling a high-level production rhythm of:
- One storage PACK produced every 15 seconds
- One inverter produced every 21 seconds
Supported by capabilities such as fully automated PACK welding, advanced SMT automated lines, and high-efficiency DIP lines, the Center forms a modern intelligent manufacturing system integrating high-precision production, three-dimensional logistics, and closed-loop quality traceability.
In Sigenergy’s view, manufacturing capability is a direct part of product reliability. Consistency, precision, and quality control in production translate into the long-term stability that customers depend on—whether in premium residential markets or in large, complex commercial and utility environments.
Green Manufacturing in Practice: Producing Clean Energy the Clean Way
As a company building solutions for a low-carbon future, Sigenergy also believes renewable energy products should be made in a renewable-minded way. The Nantong Smart Energy Center is equipped with 3 MW of onsite photovoltaics and a 3 MWh energy storage system, enabling energy collaboration management and supporting higher comprehensive energy utilization efficiency within the manufacturing process.
It is a practical expression of Sigenergy’s sustainability commitment: not only enabling customers to reduce carbon emissions through clean energy systems but also embedding low-carbon principles into the way those systems are made.
“AI in All”: A Strategy for Energy Systems That Think, Coordinate, and Improve
At the launch event, Sigenergy officially introduced its “AI in All” development strategy—an ambitious blueprint to embed artificial intelligence deeply across products, software, manufacturing, and energy management systems. Sigenergy’s vision is to move energy systems from simply “running” to becoming systems that can think, coordinate, and continuously optimize.
In Sigenergy’s perspective, AI is not a decorative feature added to hardware. It is meant to be a foundational capability that improves decision-making, simplifies interaction, and enhances system-level coordination across residential, commercial, and utility scenarios. The objective is clear: energy systems that are not only efficient, but also more intuitive to use, easier to manage, and smarter in real-world operations.
Full-Spectrum Product Launch: New Solutions Across Residential, C&I, and Utility-Scale
To demonstrate the strategy in action, Sigenergy also unveiled a set of new products spanning all major application scenarios—further strengthening its platform approach to smart energy.
Residential: SigenStor Neo—Next-Generation Home Energy, Made Simpler
Sigenergy launched SigenStor Neo, a new-generation home energy system that continues Sigenergy’s signature integrated, stackable design language. It combines key functional modules into a highly unified solution, further enhancing integration and adaptability for modern households, delivering a more seamless, more intelligent, and more user-friendly home energy experience.
Commercial & Industrial: 166 kW PV Inverter + SigenStack Modular Storage
For C&I users, Sigenergy introduced a 166 kW PV inverter, designed to improve generation efficiency with high power density and advanced power electronics. Alongside it, SigenStack, a modular storage solution, brings flexible scalability from 50 kWh to 10 MWh, enabling tailored configurations for industrial parks, commercial complexes, and diverse enterprise energy needs.
Utility-Scale: Ground-Mounted Inverter—Built for Higher Voltage, Higher Intelligence
For large-scale PV plants, Sigenergy launched its ground-mounted inverter, designed to reduce system cost and enhance overall efficiency. Key highlights include:
- Maximum output power up to 500 kW per unit
- Support for 1,650 V DC input and 1,000 V AC systems
- Up to 18 MPPTs, with strong adaptability in complex scenarios
- Advanced arc fault detection with AFCI distance up to 500 meters
- MPPT-level fault localization and intelligent diagnostics to improve operational efficiency
Sigenergy also emphasized the role of AI in utility-scale operations, applying data-driven intelligence to improve PV power forecasting and support better dispatch and revenue optimization—helping large plants progress from “efficient generation” toward intelligent operation.
A Global Trajectory: Built Fast, Built Strong, Built for the Future
Founded in May 2022 and headquartered in Shanghai, Sigenergy is a technology-driven innovator focused on the deep integration of power electronics, digital technologies, and AI, spanning solar PV, smart energy storage, and EV charging. In just over three years, Sigenergy has expanded rapidly, with 1,000+ employees, a broad global footprint, and a growing partner ecosystem including 100 core distributors and 20,000+ installer partners.
Sigenergy’s momentum has been powered by product innovation and market execution—establishing a strong presence in premium markets such as Australia and Europe and building a recognizable advantage in distributed energy systems through integrated design, intelligent control, and user-centric experience.
Looking Forward: Nantong as a Global Anchor for Intelligent, Reliable Delivery
The Nantong Smart Energy Center is a new anchor point in Sigenergy’s global journey—supporting stronger delivery capacity, higher manufacturing consistency, and faster scaling of new products worldwide. Going forward, Sigenergy will deepen the synergy between Shanghai’s R&D strengths and Nantong’s manufacturing strengths, building a more integrated global industrial loop and striving to develop Nantong into a leading demonstration site for intelligent PV-storage manufacturing.
With a new Center, a new strategy, and a renewed full-scenario portfolio, Sigenergy is stepping into its next stage with clarity: advancing the energy transition not only toward cleaner power, but toward smarter, safer, and continuously improving energy systems—in collaboration with partners across the globe.
