Sineng Electric has showcased its latest innovations and all-scenario energy solutions at SNEC 2026. Centred on advanced grid-forming technologies and AI-powered energy management, the company underscored its commitment to accelerating the transition toward more resilient, intelligent and future-ready energy systems.
Sineng presented its comprehensive grid-forming energy storage portfolio, compatible with 6+ MWh energy storage systems, allowing for large-scale renewable energy integration while improving grid stability, resilience and operational flexibility.
The company’s 1725 kW central PCS can be configured into solutions up to 13.8 MW. Compared with conventional solutions, it reduces overall costs by up to 38%. Supporting both grid-following and grid-forming operating modes across 2-hour, 4-hour and 8-hour systems, the solution is engineered with multi-layered protection and high environmental adaptability, capable of stable operation under demanding operating conditions.
The company’s 430 kW string PCS can be integrated into a 12.5 MW MV turnkey station with transformer, RMU and DC & AC LV panel. Leveraging advanced liquid-cooling technology, the solution achieves highly efficient thermal management, reducing internal temperature rise by 5 K while cutting auxiliary power consumption by 30%. With a modular design, it reduces downtime risks and maintenance complexity. As a result, the system ensures annual availability exceeding 99.5%, improving long-term economic value for utility-scale energy storage applications.
Driven by the growing demand for safer, smarter, and higher-value C&I energy storage solutions, the company has introduced a range of new products designed to enhance operational efficiency and investment returns.
Designed for long-duration energy storage applications, the 125 kW/488 kWh liquid-cooled C&I energy storage system adopts 587 Ah large-capacity battery cells and delivers a round-trip efficiency of over 90%, together with 100% unbalanced load capability. With three-level fire protection, AC/DC terminal temperature monitoring and self-powered fire suppression, the system provides comprehensive safety assurance across the full lifecycle. Integrated AI-powered cell health diagnostics and intelligent operational decision-making functions further enhance system intelligence, enabling smarter and more efficient operation.
Also on display was the new SN75–125HT hybrid inverter. Supporting seamless switching between on-grid and off-grid modes within 10 ms, the product guarantees uninterrupted power supply while delivering 200 kW peak power within 200 ms and 150% overload for up to 10 seconds.
The 5 MWh all-in-one energy storage system for large C&I applications integrates 6 units of 430kW liquid-cooled string PCS within a compact 20-foot design to simplify transportation, installation, and commissioning processes.
In terms of sustainable and low-carbon living for households, Sineng displayed its residential all-in-one energy storage solution, featuring 340Ah automotive-grade battery cells for enhanced safety and reliability.
Through independent battery management and mixed deployment of new and existing batteries, the solution enables flexible capacity expansion. With an 8,000-cycle warranty and multiple layers of fire protection, the system delivers enhanced reliability, safety and long-term operational stability.
The residential lineup also included 3–33 kW hybrid inverters and residential battery systems, further strengthening the company’s diversified product portfolio.
Chairman Qiang Wu commented: “As the global energy transition accelerates, Sineng Electric remains committed to continuous technological innovation. By advancing grid-forming and AI-driven energy technologies, we are dedicated to supporting the development of more resilient, efficient and sustainable power systems worldwide and accelerating progress toward a zero-carbon era.”
