Dunext Unveils C&I Energy Storage Excellence at Intersolar Europe, Advancing Its Global Market Leadership

Installers, EPCs and industry journalists alike converged on the Dunext booth, where live demos highlighted the system’s all‑in‑one cabinet and state‑of‑the‑art thermal management. Dunext experts walking visitors through every safety layer, performance parameter and diverse application scenarios, cementing Dunext’s reputation for innovation in the fast‑evolving commercial and industrial storage arena.

Why Europe Demands New-generation C&I Energy Storage

Europe’s rapid deployment of renewables like wind and solar, driven by carbon neutrality goals, has outpaced grid flexibility, resulting in instability, negative electricity prices, and forced curtailments. The recent large-scale blackout in Spain and Portugal underscores the urgent need for energy storage to stabilize supply and enhance resilience. Yet despite these growing risks, many commercial and industrial (C&I) enterprises still lack dedicated energy storage systems, leaving them fully exposed to market volatility, power disruptions, and rising energy costs. Coupled with restricted access to grid services and the high cost and complexity of traditional BESS deployments, the need for safe, scalable, and intelligent storage solutions has become not just a competitive advantage but an operational necessity.

PowerHill Series‑233 kWh Takes the Spotlight

At Intersolar Europe 2025, Dunext addressed these challenges head-on with the launch of its new PowerHill Series-233kWh liquid-cooled BESS—an all-in-one cabinet featuring 233 kWh capacity at 0.5C rates. Designed for maximum design flexibility, it integrates seamlessly with both DC-coupled PV arrays and AC-coupled inverters. A live demonstration highlighted how the liquid cooling system enhances energy conversion efficiency and extends system lifespan while enabling diverse business models such as peak shaving and grid services. Together with the existing PowerHill (143–215kWh) air-cooled system, the full PowerHill lineup offers scalable and scenario-driven storage solutions tailored to a wide range of C&I customer needs.
