MUNICH, June 24, 2026 /PRNewswire/ -- At Intersolar Europe 2026, LONGi Energy Storage officially introduced LONGi ONE to the European market, marking a key milestone in its global expansion. The company also presented OneNexus, extending the LONGi ONE portfolio to microgrid applications while strengthening its commitment to localized delivery and lifecycle support across Europe.
Designed for Reliable Energy Infrastructure
The rollout comes as European power markets continue to see increasing demand for storage systems capable of providing grid stability and long-term performance. Project developers are evaluating storage as critical infrastructure rather than standalone assets. LONGi ONE integrates PV generation, energy storage, energy management, and lifecycle services into a single system architecture that streamlines project delivery and supports long-term operational performance.
Safety as A System-level Imperative
Safety also remains a core pillar of the LONGi ONE architecture. Building on intelligent monitoring and multi-layer protection technologies, LONGi adopts a proactive approach to battery safety that emphasizes early risk identification, coordinated system management, and preventive intervention to support reliable operation throughout the asset lifecycle.
Portfolio Expansion: OneNexus for Microgrid and Distributed Applications
At Intersolar Europe 2026, LONGi Energy Storage showcased its integrated solutions across utility-scale and distributed applications. A key highlight of the exhibition was the European showcase of OneNexus, designed for microgrid and distributed energy scenarios where generation, storage, and loads operate as a coordinated local energy system, extending LONGi ONE to more flexible deployment models.
Strengthening Localized Support Across Europe
Beyond technology, LONGi continues to strengthen its localized presence in Europe through regional teams, engineering capabilities, and project execution support. With multiple deployed projects across the region, the company has accumulated practical experience in meeting Europe's stringent technical standards and regulatory requirements, while supporting customers across project delivery and long-term operation.
Backed by a service network spanning 120 countries and the "2830 Plan" (establishing 30 global local service hubs by 2028), LONGi has achieved an average MTBF of 8,500 hours for its European customer systems, with average issue resolution time shortened to within 48 hours.
A Single Point of Accountability for Long-Term Trust
With the European debut of LONGi ONE, LONGi continues to strengthen its localized approach, combining integrated system design with lifecycle expertise to support reliable solar-plus-storage projects across Europe.

LONGi Energy Storage Debuts LONGi ONE in Europe, Delivering Fully Integrated Solar-Plus-Storage with Localized Lifecycle Support
MUNICH, June 26, 2026 /PRNewswire/ -- Sunwoda, a full-scenario energy storage solution provider, participated in ees Europe 2026 in Munich, Germany, showcasing a broad portfolio of energy storage technologies spanning battery cells from 72Ah to 684Ah, alongside utility-scale and C&I energy storage solutions. The event also marked the official launch of its next-generation ESS portfolio based on Sunwoda's 588Ah high-capacity LFP cell platform.
Launch of Next-Generation 588Ah-Based ESS
The new portfolio includes a 20-foot 6.26MWh Liquid Cooling BESS, a 10-foot 3.13MWh Liquid Cooling BESS, and a 10-foot 3.13MWh All-in-One Liquid Cooling ESS, providing flexible options for different capacities and deployment requirements.
As the flagship product of the series, the 6.26MWh BESS achieves a 24.8% increase in volumetric energy density, a 17% reduction in station footprint, and a 40% reduction in total system components compared to Sunwoda's previous generation.
The platform features a multi-layer safety architecture and hierarchical electrical protection design to enhance fault isolation and system stability. An innovative liquid-cooling and airflow coordination system ensures uniform thermal distribution, while a cluster-level BMS enables active balancing. The system supports centralized and string PCS configurations and is compatible with 2-hour and 4-hour applications, enabling flexible deployment across a wide range of utility-scale projects.
Complementing the flagship system, the 10-foot 3.13MWh BESS provides a compact and flexible option for projects with complex transportation, installation, or site-layout requirements. The 3.13MWh All-In-One ESS further integrates factory-preconfigured AC/DC architectures, reducing on-site integration work and enabling faster installation and commissioning.
Advancing Safety and Compliance Milestones
During the event, Sunwoda received certificates from CSA Group confirming that its 5MWh BESS platform successfully completed large-scale fire testing in accordance with ANSI/CAN/UL 9540A:2026 and was evaluated against CSA/ANSI C800:2025 requirements, further validating Sunwoda's system-level safety.
Sunwoda's 261kWh ESS series also received certification from TÜV Rheinland under Regulation (EU) 2023/1542, confirming compliance with applicable requirements for battery lifecycle management, material traceability, and digital battery passport readiness. These regulatory validations are being extended across its broader portfolio, further enhancing Sunwoda's readiness for the European energy storage market.
Enhancing Global Presence and Localization
The launch of the 588Ah-based ESS platform, together with the latest safety and EU compliance milestones, represents an important step forward for Sunwoda. By combining advanced engineering, system-level safety design, and international compliance capabilities, Sunwoda is strengthening its European localization framework and after-sales technical support capabilities to support local energy storage deployment and the global energy transition.
