Recently, Jinko ESS, a global leading energy storage solution provider and a subsidiary of Jinko Solar Co., Ltd., showcased SunTera and SunGiga product series, alongside the BMS-EMS-OPS Cloud platform, as well as Tiger Neo 3.0 module and Anti-Dust Self-Cleaning module, at the 14th Energy Storage International Conference and Expo (ESIE 2026) in Beijing. During the exhibition, Jinko ESS hosted the UL 9540A 6th Edition (2026 Draft) Large-Scale Fire Test Certification Ceremony and the“PV-ESS-AI: Future Trinity” themed launch event, systematically presenting its latest achievements in safety, intelligent operation, and scenario-based applications through certified validation, new product unveiling, and field-proven performance data.
SunGiga 520 Debuts, SunGiga 261 Draws Strong Attention
At the product launch zone, Jinko ESS officially unveiled the SunGiga G2 Plus 522kWh liquid-cooling energy storage system (SunGiga 520). Centered on three key values—AI-enabled revenue optimization, enhanced safety, and full-lifecycle O&M—the system integrates AI-based electricity price forecasting with advanced EMS strategies to support intelligent energy trading. Its optimized liquid cooling design and grid-forming PCS enable cell temperature difference within 2℃ and seamless on/off-grid switching within ≤20ms, with an overall protection rating of IP55/C5.
Meanwhile, the SunGiga G2 261kWh liquid-cooling energy storage system, also displayed at the booth, attracted extensive attention. With its modular architecture and flexible deployment capabilities, it has become a key product for large-scale deployment of C&I energy storage.
SunTera G3 and Fully In-House Control System Portfolio
The SunTera G3 6.25MWh liquid-cooling energy storage system was also highlighted, featuring 587Ah cells and serpentine-channel liquid cooling technology, achieving a cell temperature difference of ≤2.5℃.
In addition, Jinko ESS showcased its fully in-house developed control system portfolio, including SCU, BCU, BMU, EMS1000, and the OPS cloud platform, covering the full technical chain from cell-level management to station-level dispatch and cloud-based operation and maintenance.
PV Scenario-Based Solutions and TOPCon Field Data
Also on display were the Tiger Neo 3.0 module, Anti-Dust Self-Cleaning module, and AIDC module designed for AI data centers. These products feature six core advantages, including high efficiency, high bifaciality, strong low-irradiance performance, enhanced fire safety rating, hail resistance, and high mechanical load capacity, meeting the stringent requirements of next-generation energy infrastructure.
According to the latest field data from Jinko's global test sites, TOPCon modules demonstrate consistently strong performance across multiple locations, achieving up to 8.36% higher energy yield per watt compared to BC modules. Tiger Neo 3.0 modules also deliver over 3% gains in both C&I and residential scenarios, with superior partial shading tolerance and hot-spot control compared to BC products.
Exhibition Highlights and Outlook
During the exhibition, Jinko ESS held the “UL 9540A 6th Edition (2026 Draft) Large-Scale Fire Test Certification Ceremony for SunTera Energy Storage Systems”, validating its system-level fire protection and thermal runaway mitigation capabilities in line with leading international standards. The company also hosted technical sessions covering C&I energy storage, Full-Scenario PV+ESS Solution for AIDC, TOPCon field validation, and virtual power plant (VPP) aggregation.
Damon Duan, General Manager of Jinko ESS China, stated during the media briefing, “Our presence at ESIE 2026 represents a comprehensive showcase of Jinko ESS's full-stack capabilities. From AI-enabled revenue optimization with SunGiga 520 to the high-performance and safety of SunTera G3, from grid-forming support to our fully in-house control systems, we are evolving from an equipment provider into an integrated energy ecosystem builder combining PV, ESS, and AI. Moving forward, Jinko ESS will continue to drive innovation and support the global transition toward safer, smarter, and more efficient energy systems.”
