Sigenergy Opens Nantong Smart Energy Center with AI Focus

On March 13, 2026, Sigenergy celebrated a significant milestone with the inauguration of the Sigenergy Nantong Smart Energy Center located in Nantong, Jiangsu Province, China. This facility is a testament to the company's ambitious vision, attracting over 2,000 distinguished guests from more than 50 countries to witness this landmark event. At the center of the inauguration was the unveiling of the 'AI in All' strategy, alongside innovative product offerings that signify the next phase of rapid global business growth for Sigenergy.

The 'AI in All' Strategy

Sigenergy's 'AI in All' approach places artificial intelligence at the forefront of all operations, evolving the company from basic functions to creating intelligent, interconnected, and continuously optimized energy systems. According to Tony Xu, founder and CEO of Sigenergy, "We aim to lead the global energy transition through 'AI in All' innovations." This strategy highlights Sigenergy's commitment to utilizing AI to develop smarter and more adaptable energy systems while setting industry standards that align with the changing landscape of renewable energies and storage technologies. The ongoing shift within the industry is moving focus from standalone hardware to integrated systems designed around user experiences. By employing AI as the fundamental technology, Sigenergy enhances energy management, ensuring efficient optimization, even in complex scenarios for residential, commercial, and utility applications.

Nantong Smart Energy Center: A Benchmark in Intelligent Production

The newly launched Nantong facility spans an impressive 136,000 square meters, built with an investment of 500 million RMB (approximately 70 million USD). It boasts an annual production capacity exceeding 300,000 inverters and battery packs. More than just a manufacturing site, it integrates advanced research and development, smart manufacturing capabilities, and global logistics. This center embodies the heart of Sigenergy's manufacturing network, featuring a fully digital platform that supervises production in real-time while coordinating processes across the entire facility. Unlike traditional factories reliant on isolated automation, Nantong employs interconnected systems for manufacturing control, warehouse management, and energy management. This interconnectedness seamlessly synchronizes material dispatch, equipment configuration, and production adjustments, resulting in industry-leading precision across all manufacturing stages.

The integration of visual inspection technologies like Charge-Coupled Device (CCD) for automated welding achieves an astounding 99.9% yield, while Surface-Mount Technology (SMT) lines process components at speeds of 0.043 seconds per unit, with accuracy levels of 20 to 30 microns. Moreover, the advent of AI-driven quality checks replaces manual sampling procedures, and the three-dimensional smart logistics system optimizes material transportation. Overall, this combination of sophisticated technology and intelligent systems sets new standards for throughput, achieving the production of one battery pack every 15 seconds and one inverter every 21 seconds. The Nantong Smart Energy Center, thus, signifies a major leap in mass production, equipping Sigenergy to enhance both output and established product quality, ensuring high precision, consistency, and long-term reliability.

New Product Innovations

Accompanying the factory's inauguration, Sigenergy proudly introduced three new product lines aimed at enhancing its portfolio in residential, commercial, and utility sectors.

1. SigenStor Neo: A New Residential Energy Storage Solution

The SigenStor Neo represents Sigenergy’s latest residential energy storage system, showcasing modular architecture and a unique circular light ring design. This all-in-one system integrates essential components including a PV inverter, battery packs with management systems, and an Energy Gateway for backup power.

2. Advanced PV Inverter for Commercial Applications

The company also launched a powerful 166 kW PV inverter designed for commercial use. Leveraging advanced power electronics, it offers higher performance density and enhanced system efficiency for enterprise customers looking to more effectively integrate PV with storage systems.

3. Utility-Specific High-Power Inverter

In the utility domain, Sigenergy revealed an innovative utility inverter boasting a capacity of up to 500 kW and supporting DC input voltages of up to 1650 V. The new 1000 V AC standard exemplifies Sigenergy's efforts to reduce system costs while improving overall energy generation efficiency. With 18 MPPTs, it allows for the management of higher energy yields over challenging terrains and features advanced safety mechanisms, including AFCI detection up to 500 meters. Furthermore, its intelligent maintenance functions, including MPPT-level fault detection and real-time monitoring, empower operators to optimize performance and reduce costs.

Through these product innovations, Sigenergy is set to provide tailored energy solutions across residential, commercial, and utility applications, further cementing its role as a leading player in the global energy landscape.

The Nantong Smart Energy Center not only enhances Sigenergy’s production capabilities, but also paves the way for a smarter, more integrated energy future powered by AI technologies.
