Contemporary Nebula Technology Energy (CNTE) has launched two new energy storage systems at Intersolar/The smarter E Europe 2026 in Munich. The first of these is its new-generation STAR H-MAX liquid-cooled C&I ESS, further expanding its flexible MWh+ energy storage portfolio for global markets.
Designed for evolving commercial and industrial energy demands, the STAR H-MAX integrates 220kW / 440kWh capacity into a compact outdoor all-in-one architecture, helping customers achieve peak-valley arbitrage, backup power support and grid-interactive energy management.
Built with CATL LFP 530Ah battery cells, the system delivers over 10,000 cycles of lifespan while supporting both 0.5P and 0.25P dual configurations, allowing users to flexibly balance between high-power output and long-duration energy supply across different operating scenarios. The system adopts a transformer-free design with direct load integration for C&I applications, significantly reducing installation complexity, deployment costs and footprint requirements. Each unit occupies only 2.03m², while supporting parallel expansion up to 4.4MWh, making it suitable for factories, industrial parks and distributed energy projects.
To ensure stable operation in diverse environments, the system integrates AI smart temperature control technology, supporting operating temperatures from -25°C to 55°C while maintaining precise thermal management with cell temperature differences within 3°C. The product also operates at just 65dB, enabling deployment in noise-sensitive environments.
For energy resilience and advanced grid services, STAR H-MAX supports seamless grid/off-grid switching through STS technology and delivers fast frequency regulation response times below 250ms at system level, supporting applications including aFRR, mFRR, and FCR. The product has obtained multiple international certifications, including IEC 62619, 63056, 60730-1, 62477-1 and 61000-6-2&4, as well as UN38.3, and is certified for grid connection in 45 countries across Europe, Africa and Asia.
The second product launched in Munich is the STAR X liquid-cooled DC/AC integrated ESS. This latest utility-scale storage innovation redefines large-scale energy storage through highly integrated architecture, intelligent operation, flexible deployment and enhanced safety performance.
Designed for utility-scale and advanced commercial applications, STAR X delivers up to 2800kW / 5644kWh in a highly integrated architecture that combines the battery system and liquid-cooled grid-forming PCS within a single cabinet. With fully internal DC cabling and factory pre-installation and pre-commissioning, the system significantly improves safety while accelerating project deployment.
Powered by CATL’s third-generation 530Ah large-capacity battery cells, STAR X achieves over 10,000 cycles (@70% SOH) and is among the industry’s first integrated liquid-cooled ESS solutions equipped with 530Ah battery packs. The system also adopts CNTE’s cluster-level intelligent control technology, enabling independent cluster management and fault isolation to maintain over 99% system availability. By eliminating cluster imbalance and circulation loss, STAR X improves full lifecycle discharge capacity by 6% while extending system lifespan by 5%.
To support diverse project scenarios, the product offers flexible configurations ranging from 1MW/2MWh to 2.8MW/5.6MWh, with selectable 0.5P high-power mode or 0.25P four-hour duration mode. Its transport-friendly design keeps total system weight within 45 tons, meeting international land and sea transportation requirements.
The system further simplifies operation and maintenance through one-click startup and shutdown, APP-based commissioning, OTA remote upgrades, AI-powered fault diagnosis, intelligent lifespan prediction and automatic SOC calibration, greatly reducing onsite maintenance complexity. For safety, STAR X incorporates a comprehensive multi-level protection architecture covering cell, module, cluster and container levels, alongside 24/7 online insulation monitoring for enhanced operational reliability. Designed for applications including peak shaving, renewable energy integration, frequency regulation, microgrids and grid-forming support, STAR X demonstrates CNTE’s continued commitment to accelerating the global energy transition through advanced energy storage technologies.
