261 kWh is now the C&I standard—Ecosolex already delivers it across Europe, plus full-scenario storage and in-house EMS/BMS/PCS
Ecosolex, the energy storage brand of Topband New Energy, is presenting its commercial, industrial and residential energy storage portfolio at ees Europe 2026 in Munich, Germany.
The company is exhibiting at Hall C2, Booth 320, where it is showcasing a range of integrated energy storage systems, modular C&I storage solutions, large-scale containerized systems, residential storage products, and its cloud-based energy management platform.
The portfolio is designed to address applications across commercial and industrial facilities, industrial parks, distributed renewable energy projects, EV charging infrastructure and residential energy use cases.
Standardized C&I storage systems
At the core of the portfolio is the EcoStor C Series, which includes the M125G261A and P125G261A liquid-cooled all-in-one energy storage systems.
Both systems are based on a 125 kW / 261 kWh configuration, which has become a widely adopted format in European C&I storage projects due to its balance between capacity, footprint and deployment efficiency.
The M125G261A integrates LFP battery modules, battery management system (BMS), power conversion system (PCS), energy management system (EMS), thermal management and fire protection within a single cabinet. It is designed for applications including peak shaving, PV self-consumption and commercial energy cost management.
The P125G261A extends system functionality to hybrid applications, supporting PV generation, diesel generator integration and grid interaction. It enables functions such as backup power switching, anti-backfeed protection, reactive power control and coordinated energy dispatch.
Flexible deployment solutions
For smaller and more flexible C&I applications, Ecosolex is presenting its Flexo Series.
The Flexo 50 is a 30 kW / 50 kWh all-in-one system designed for small commercial facilities, EV charging sites and distributed PV-storage applications. It features a pre-integrated cabinet design that reduces on-site installation complexity and supports fast deployment.
The Flexo 200 system targets medium-sized commercial and industrial projects requiring scalable capacity and outdoor installation flexibility. It is designed for applications such as industrial facilities, logistics centers and distributed energy sites.
Large-scale C&I and industrial storage systems
For industrial parks and large-scale user-side applications, Ecosolex is showcasing the Valtrix String 3.0 containerized energy storage system.
The system is based on a 1.5 MW / 3.13 MWh string architecture and is designed to support higher system granularity, improved fault isolation and enhanced operational safety. It uses cluster-level battery management, precision thermal control and multi-layer safety design.
Ecosolex said the Valtrix String 3.0 system has recently completed factory testing and shipment for a project in the Czech Republic, marking a new delivery milestone for the company in the European market.
In addition, Ecosolex is presenting the Valtmax 800 system, which features a 215 kW / 418 kWh configuration and a transformerless 800V architecture. The system is designed for large-scale commercial and industrial applications, focusing on improved efficiency and reduced balance-of-system costs.
European project deployments
Ecosolex also highlighted its ongoing project deployments in Europe.
In Spain, the company has delivered a 125 kW / 261 kWh integrated energy storage system for a project in Western Granada. The system is used for backup power applications, supporting local commercial energy resilience requirements.
Together, the Czech Republic shipment and Spain deployment reflect Ecosolex’s growing presence in distributed C&I energy storage projects across Europe.
Residential energy storage portfolio
Alongside its C&I systems, Ecosolex is also presenting residential energy storage solutions, including the Opti L16 high-capacity battery system, a 6 kW all-in-one energy storage system, and high-voltage and low-voltage rack battery platforms.
These systems are designed for residential applications such as solar self-consumption, backup power and energy cost optimization.
Digital energy management platform
Ecosolex is also demonstrating its Ecosolex Cloud platform, which enables centralized monitoring and management of distributed energy assets, including solar PV, energy storage systems and energy consumption data.The platform supports remote monitoring, system diagnostics, data visualization and energy optimization functions, allowing users to manage distributed energy assets through a unified interface.
Ecosolex said its participation at ees Europe 2026 reflects its strategy to provide integrated energy storage and management solutions across commercial, industrial and residential applications.The company aims to support the transition toward more distributed, digital and flexible energy systems through standardized C&I platforms, scalable storage architectures and cloud-based energy management capabilities.
