Enerbond/GTCAP 261kWh Liquid-Cooled Energy Storage Cabinet Achieves CEI 0-21 and CEI 0-16 Certifications

Enerbond/GTCAP's 261kWh liquid-cooled all-in-one energy storage cabinet has officially obtained both CEI 0-21 and CEI 0-16 certifications, issued by TÜV, a globally recognized testing and certification organization.

The achievement marks an important milestone for Enerbond/GTCAP in product compliance, grid adaptability, and international market access. It also provides stronger technical support for the company's continued expansion across the European commercial and industrial energy storage market.

In parallel, Enerbond/GTCAP has initiated certification activities for the North American market, further strengthening the compliance foundation required to support energy storage projects across both Europe and the United States.

CEI 0-21 and CEI 0-16: Supporting Energy Storage Deployment in Italy

Italy is one of Europe's key energy storage markets and maintains strict technical requirements for grid-connected power equipment.

For energy storage systems entering the Italian market, compliance with relevant grid connection standards is essential for ensuring safe and reliable interaction with the local electricity network.

CEI 0-21 specifies technical requirements for equipment connected to low-voltage distribution networks, covering areas such as system performance, protection, safety, and grid interaction.

CEI 0-16, meanwhile, defines technical requirements for equipment connected to medium- and higher-voltage networks, including grid support, reactive power regulation, protection, and system response.

By achieving both CEI 0-21 and CEI 0-16 certifications, the Enerbond/GTCAP 261kWh C&I energy storage system is better positioned to support a broad range of grid connection scenarios, from low-voltage applications to medium-voltage energy storage projects.

This provides greater deployment flexibility for applications such as factories, commercial buildings, industrial parks, shopping centers, distributed solar projects, and other commercial and industrial energy storage scenarios.

261kWh Liquid-Cooled All-in-One C&I Energy Storage System

The certified product is the Enerbond/GTCAP Capmega Series 261kWh liquid-cooled all-in-one energy storage cabinet, developed specifically for global commercial and industrial (C&I) energy storage applications.

The system adopts a highly integrated all-in-one architecture, combining key components within a single cabinet, including:

• Battery system
• Battery Management System (BMS)
• Energy Management System (EMS)
• Power Conversion System (PCS)
• Liquid cooling system
• Fire protection system

This integrated design reduces the complexity of on-site installation and system integration while helping shorten project deployment time and simplify long-term operation and maintenance.

Compared with conventional multi-component energy storage installations, the standardized cabinet architecture can also help reduce engineering workload and overall deployment costs, making it particularly suitable for scalable commercial and industrial energy storage projects.

Liquid Cooling for Stable and Efficient Battery Operation

Thermal management is a critical factor affecting the performance, safety, and service life of battery energy storage systems.

The Capmega 261kWh energy storage cabinet uses a liquid cooling thermal management system to maintain a more stable operating temperature across the battery modules.

More consistent temperature control can help reduce temperature differences between cells, support battery performance, and improve long-term system reliability under demanding operating conditions.

For commercial and industrial users requiring frequent charging and discharging cycles, stable thermal management is especially important for maintaining predictable system performance throughout the lifecycle of the energy storage system.

Solid-State Battery Technology for Enhanced Energy Storage Safety

Safety remains one of the most important considerations in commercial and industrial battery storage.

The Enerbond/GTCAP 261kWh energy storage system incorporates solid-state battery technology, using solid electrolyte materials to improve battery stability compared with conventional liquid-electrolyte designs.

The use of solid-state electrolyte technology can help reduce risks associated with electrolyte leakage, flammability, and thermal instability, providing an additional layer of safety for energy storage applications.

The cabinet also incorporates multiple levels of system protection and fire suppression design to enhance operational safety in demanding environments such as factories, industrial facilities, commercial buildings, and shopping centers.

This multi-layer safety strategy combines battery-level protection, intelligent battery management, thermal management, system monitoring, and fire protection to support more reliable long-term operation.

Intelligent BMS, EMS and Cloud-Based Energy Management

In addition to hardware safety, intelligent monitoring plays an increasingly important role in modern C&I energy storage systems.

The Enerbond/GTCAP Capmega Series integrates intelligent BMS and EMS capabilities to continuously monitor battery operating conditions and overall system performance.

Through data analysis and intelligent diagnostics, the system can support battery health assessment, operational status monitoring, and remote fault diagnosis.

Cloud-based energy management also enables operators to monitor system performance remotely, improving visibility across distributed energy storage assets and helping simplify operation and maintenance.

These intelligent capabilities are designed to meet the growing demand for safer, more reliable, and more manageable commercial and industrial energy storage solutions.

Strengthening Enerbond/GTCAP's Global Energy Storage Strategy

Obtaining both CEI 0-21 and CEI 0-16 certifications represents another important step in Enerbond/GTCAP's international market strategy.

As global demand for commercial and industrial energy storage systems continues to grow, technical compliance and grid adaptability are becoming increasingly important factors for energy storage manufacturers, distributors, EPC companies, and project developers.

Enerbond/GTCAP continues to develop its capabilities across battery technology, system integration, intelligent energy management, thermal management, and energy storage safety.

With a technology platform covering battery applications, BMS, EMS, PCS integration, liquid cooling, intelligent monitoring, and system-level safety design, Enerbond/GTCAP aims to provide reliable and scalable energy storage solutions for customers worldwide.

The CEI 0-21 and CEI 0-16 certifications further strengthen the market readiness of the Capmega 261kWh liquid-cooled C&I energy storage system and provide a solid foundation for future deployment across Europe and other international markets.
