Together for a Zero-Carbon Era: Sineng Electric Unveils All-Scenario Energy Storage Solutions at SNEC 2026

Shanghai, China, June 4, 2026 - Sineng Electric, a global leader in solar PV, energy storage, and hydrogen solutions, showcased its latest innovations and all-scenario energy solutions at SNEC 2026. Centered 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.

Building a More Stable Grid with Grid-Forming Energy Storage Solutions for Utility-Scale Applications

At SNEC 2026, Sineng Electric 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.

With millisecond-level dynamic response and high-precision power control, the PCS delivers superior frequency regulation performance, achieving an industry-leading Composite Frequency Response Coefficient (K) and enabling precise, stable active power support under fast grid fluctuations.

Sineng'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-cooled 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, the solution 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.

AI-Driven C&I Energy Storage Solutions Unlocking Higher Safety and Economic Value

Driven by the growing demand for safer, smarter, and higher-value C&I energy storage solutions, Sineng Electric 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%, along with 100% unbalanced load capability. With the 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.

Sineng Electric also officially launched the SN75–125HT hybrid inverter. Supporting seamless switching between on-grid and off-grid modes within 10 ms, the inverter guarantees uninterrupted power supply while delivering 200 kW peak power within 200 ms and 150% overload for up to 10 seconds.

Supporting VSG and VF micro-grid control modes alongside a built-in diesel generator interface, the solution is well-suited for hybrid and off-grid scenarios. Its 42 A high-current MPPT design and dual 150 A battery ports provide enhanced compatibility with high-power PV modules and large-capacity battery systems.

Additionally, Sineng Electric showcased its 5 MWh all-in-one energy storage system for large C&I applications, integrating 6 units of 430kW liquid-cooled string PCS within a compact 20-foot design to simplify transportation, installation, and commissioning processes.

Residential Solar-Plus-Storage Solutions Empowering Smarter Home Energy Management

In support of sustainable and low-carbon living for households, Sineng Electric 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. In addition, AI-powered charge and discharge optimization strategies enable intelligent energy management based on household consumption patterns and time-of-use electricity tariffs.

The residential lineup also included 3–33 kW hybrid inverters and residential battery systems, further strengthening Sineng Electric’s diversified product portfolio.

"As the global energy transition accelerates, Sineng Electric remains committed to continuous technological innovation," said Qiang Wu, Chairman of Sineng Electric. "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."
