CNTE Unveils STAR H‑PLUS Energy Storage System at KEY ENERGY 2026

Contemporary Nebula Technology Energy (CNTE), a prominent global player in the energy storage sector funded by CATL, recently showcased its groundbreaking STAR H‑PLUS energy storage system at the KEY ENERGY 2026 event in Rimini, Italy. This innovative outdoor energy storage solution emphasizes a commitment to performance, safety, and lifecycle value, catering to a diverse range of energy storage needs globally.

Overview of STAR H‑PLUS

The STAR H‑PLUS is equipped with a robust 125 kW / 254 kWh capacity and integrates intelligent thermal management along with high energy density, promoting simplified operations. With an impressive energy density of 83.6 kWh/m³, the system allows up to 14 units (totaling 3.56 MWh) to fit within a standard 40-foot container, significantly reducing transportation and storage costs.

Maintenance and Operational Efficiency

Designed with ease of maintenance in mind, the STAR H‑PLUS features a one-button start/stop function, facilitating quick deployment and operation. A lightweight configuration tool replaces traditional software methods, ensuring quick access for maintenance. The innovative liquid cooling system not only promotes automatic coolant replenishment but also features a gas detection sensor requiring no maintenance for a decade, effectively reducing operational costs.

Performance and Noise Management

The STAR H‑PLUS operates at a noise level of approximately 65 dB under full load, making it suitable for noise-sensitive areas. The AI-based adaptive temperature control mechanism keeps the cell temperature variance within 3° C, enhancing longevity and performance despite extreme conditions. With a lifecycle exceeding 10,000 cycles, powered by CATL LFP cells rated at 306 Ah, the STAR H‑PLUS achieves a remarkable round-trip efficiency of over 88%. Optional 314 Ah cells can be implemented for specific project requirements.

Configurable and Scalable

The system supports parallel operation for up to 10 units (2.54 MWh) and allows for rapid frequency adjustment, with response times below 200 ms. Integrated with a Static Transfer Switch (STS) cabinet, it ensures seamless switching between grid-connected and off-grid modes for uninterrupted power supply.

Global Certification and Standards

Achieving compliance with grid requirements across 45 countries and holding the IEC and UN38.3 certifications, the STAR H‑PLUS is designed for reliable international deployment.
