/PRNewswire/ –CLOU Electronics, a BNEF Tier 1 provider of energy storage systems, showcased its next-generation liquid-cooled energy storage systems for commercial and industrial applications (C&I) models at the Solar Energy Expo Aqua-E261 and Aqua-X261. The company also showcased its portfolio of integrated solutions, including the Aqua-C3.0 series of liquid-cooled utility-scale energy storage systems.
CLOU received the Excellence Award in Energy Storage Category from exhibition organizer PTAK WARSAW EXPO
Aqua-E261 and Aqua-X261 C&I Storage Systems
For its groundbreaking products and solutions, CLOU was awarded the Excellence Award in the energy storage category by trade fair organizer PTAK WARSAW EXPO. The company thus received significant recognition in the industry for the further development of energy storage technology and the scaling of applications.
Energy storage technology accelerates the energy transition in Europe and helps companies significantly reduce their electricity costs, for example through peak load capping and valley filling, self-consumption from photovoltaics (PV) and electricity arbitrage. Millisecond emergency response ensures critical operations remain uninterrupted. Nevertheless, the industry faces three major challenges: eliminating revenue bottlenecks, increasing operational efficiency and strengthening security precautions.
Aqua-E261- und Aqua-X261-C&I-Storage systems: Ultimate security, maximized returns
As flagship products in CLOU’s liquid-cooled C&I energy storage series, the Aqua-E261 and Aqua-X261 are equipped with 314 Ah battery cells and up to 261 kWh of storage capacity. Both models are certified according to IEC, UN and CE standards. The Aqua-X261 is CLOU’s first integrated PV and energy storage system, offering optional 120 kW PV and STS modules.
Ultimate security
In the electrical circuit, both products have one four-stage overcurrent protection on Battery pack, cluster, PCS and control cabinet levelto achieve precise and quick shutdown level by level. In the thermal cycle a three-stage system security design with “early warning, exhaust ventilation and fire protection” used so that proactive intervention can be made before thermal runaway occurs. Active ventilation combined with fire suppression at cabinet leveladditionally protects the neighboring systems.
AI Smart Monitoringprovides real-time data, displays cell abnormalities and thermal runaway risks, and reduces thermal runaway damage. In addition, the European solution operates the central control and monitoring platforms on local servers, thereby meeting the region’s strict reliability standards.
Maximized return
In terms of yield, the product achieves Through balanced heat dissipation at the battery pack and cell level, a cell temperature difference of ≤2.5°Cwhich extends the life of the system by 2 years with two charging and two discharging cycles per day.
Midea’s proprietary AI temperature control technology reduces auxiliary energy consumption by 30% with extremely low static losses. In conjunction with a powerful PCS and an intelligent planning strategy of the energy management system (EMS), the system achieves a maximum system efficiency of ≥ 90%.
The standardized modular design allows for flexible capacity expansion, while on-site pre-commissioning reduces construction time by 50%. The updated EMS offers intelligent operation and maintenance functions. An AI diagnostic system performs real-time failure analysis, enables 15-minute algorithm updates, and dynamically optimizes scheduling for maximum cycle efficiency.
Aqua-C storage systemson a utility scale: Ultimate performance, global reach
In addition to the new storage offerings for residential and business customers, CLOU also presented several liquid-cooled energy storage systems for utilities. The flagship Aqua-C2.5 product, already in commercial use worldwide, achieves groundbreaking results in safety, performance and integrated innovation. As CLOU’s first utility-scale energy storage system with fully proprietary String-PCS core technology, it meets and exceeds stringent North American, European and international compliance requirements. This product enables global market penetration and demonstrates CLOU’s dual leadership in energy storage technology and commercial implementation.
Building on the core technologies of the Aqua-C2.5, CLOU launched the liquid-cooled energy storage systems Aqua-C3.0 and Aqua-C3.0 Pro in 2025, responding to the application trend in the current era of large cells. The Aqua-C3.0 is equipped with a 587 Ah battery cell with high energy density and a capacity of 6.25 MWh for a single control cabinet. Based on CLOU’s self-developed active balancing technology, string PCS and integrated AC/DC design, the discharge capacity is increased by 4% over the entire life cycle and a system RTE of ≥91.5% is achieved.
The Aqua-C3.0 Pro is equipped with a 600+Ah ultra large capacity cell that has a capacity of up to 7,354MWh in a single housing. With numerous technological innovations such as direct cooling, active balancing, SIC string PCS and integrated CTR architecture, it achieves a significant leap in system efficiency, safety and ease of operation and maintenance, thereby defining a new generation of energy storage systems.
Midea Group drives empowerment and accelerates global deployment
CLOU’s energy storage products and solutions are used worldwide. In Europe, cumulative orders for major projects exceed 1.5GWh, affecting Greece, Bulgaria, Romania and North Macedonia. For C&I storage, CLOU operates more than 250 locations in China, more than 20 in Southeast Asia and more than 50 in Europe (UK, Germany, Netherlands, Switzerland, Poland, Czech Republic). These European locations enable a variety of application scenarios, such as peak load capping and valley filling, demand management, integration of photovoltaics and energy storage, and virtual power plants.
CLOU’s significant growth in global energy storage markets provides a strong foundation for the company’s future. At this crucial time, Midea Group launched its New Energy division in December 2025. As the core of Midea’s energy strategy, CLOU will draw on the Group’s extensive resources, with its research and development fully supported by the Corporate Research Center. With the comprehensive support of Midea Group, CLOU will expand its capabilities and accelerate its global expansion.
