Contemporary Nebula Technology Energy (CNTE) is unveiling its latest innovation, the STAR H‑PLUS outdoor liquid‑cooled all-in-one energy storage system, at the 2026 edition of Key Energy in Rimini, Italy, the flagship product underscoring the company’s commitment to performance, safety and lifecycle value in outdoor energy storage.
The system (125 kW / 254 kWh) integrates intelligent thermal control, high energy density and simplified operation to meet diverse global energy storage needs. With an energy density of 83.6 kWh/m³, up to 14 units (3.56 MWh) fit into a 40‑ft container, reducing transport and storage costs.
Its maintenance-friendly design streamlines field service, with one-button start/stop enabling fast commissioning, a lightweight configuration tool replacing traditional software and rear-access service plus quick connectors reducing maintenance time. The liquid cooling system supports automatic coolant replenishment and the upgraded combustible gas detector is maintenance-free for 10 years, lowering operational costs.
STAR H‑PLUS operates at ~65 dB under full load, suitable for noise-sensitive sites, while AI-driven adaptive temperature control maintains cell variance at ≤3 °C, enhancing longevity and stability in extreme conditions.
Powered by CATL LFP 306 Ah cells with ≥10,000 cycle life, the product delivers >88% round-trip efficiency, with optional 314 Ah cells supporting specific project needs. The system allows parallel operation of up to 10 units (2.54 MWh) and rapid frequency regulation (<200 ms response) and, paired with an STS transfer cabinet, it ensures seamless switching between grid-tied and off-grid modes for uninterrupted power.
Already meeting grid requirements in 45 countries and holding IEC and UN38.3 certifications, STAR H‑PLUS is ready for reliable international deployment.
