Warsaw, Poland | January 2026 – At Solar Energy Expo Warsaw 2026, energy storage manufacturer AlphaESS presented its latest energy storage portfolio covering residential, commercial and industrial (C&I), and Utility-Scale, including the first offline European appearance of its new large C&I liquid-cooling systems, Aster TB250/TB500 and STORION-LC 836.
The showcase comes as utilities, private power companies and industrial users in Poland increasingly move from planning to execution of energy storage projects, driven by policy support, grid constraints and rising electricity price volatility.
Dos nuevos sistemas grandes C&I que abordan necesidades reales industriales, comerciales y de la red
At the exhibition, AlphaESS introduced two new liquid-cooled systems designed specifically for high-load, high-utilisation environments.
AlphaESS highlighted Aster TB250/TB500, a 400V/800V liquid-cooled battery energy storage system rated at 250–500 kW with energy capacities from 705 to 1,410 kWh, packaged in a 20-foot container for deployment at large factories and PV power plants.
AlphaESS also presented STORION-LC 836, a liquid-cooled outdoor cabinet energy storage system designed for commercial and industrial applications. With a single-unit capacity of 836 kWh, the system supports parallel operation of up to 8 cabinets to 1 DC input, enabling MWh-scale deployment for C&I and even large-scale storage projects. Its cabinet-based architecture and flexible transport approach simplify logistics and support phased installation and scalable project development across a wide range of sites.
Both systems are engineered with simplified installation, grid compatibility and long-term operation in mind, and incorporate UL 9540A-compliant, multi-layer fire protection and electrical safety designs to reduce complexity, downtime and operational risk.
Cartera completa en exposición: desde proyectos residenciales hasta proyectos a escala de red
In addition to the new large C&I systems, AlphaESS showcased products already deployed across different market segments.
- Residencial, Serie SMILE-G3: Sistemas modulares de almacenamiento residencial ampliables hasta 111,6 kWh, cuyo diseño se orienta a hogares que combinan energía fotovoltaica y almacenamiento bajo el programa polaco Mój Prąd. Los sistemas admiten un mayor autoconsumo, energía de respaldo y una mayor independencia energética para los usuarios residenciales.
- Comercial e industrial, STORION-H30/H50-G3 y STORION TB125: Los equipos STORION-H30/H50-G3 son sistemas de almacenamiento híbrido C&I compactos de 30 kW y 50 kW, escalables en paralelo hasta 500 kW y 2,4 MWh. Su diseño se orienta a aplicaciones «detrás del contador» en emplazamientos comerciales pequeños y de industria ligera. El STORION TB125 es un sistema C&I con acoplamiento en CA de 125 kW y 261 kWh que admite el funcionamiento en paralelo de hasta 50 unidades. Esto permite una implementación escalable para proyectos comerciales e industriales de mayor envergadura que requieran una expansión flexible de la capacidad.
- A gran escala, Aster 5000: El Aster 5000 es un sistema de almacenamiento de energía de 5 MWh alojado en un contenedor de 20 pies. Su desarrollo se orienta a la regulación de frecuencia, el soporte de picos de demanda y la integración a gran escala de energías renovables en aplicaciones conectadas a la red.
This portfolio positions AlphaESS to support both behind-the-meter projects at industrial sites and grid-side projects led by utilities and power companies.
El entorno político de Polonia respalda la inversión en almacenamiento.
Poland is expanding policy support for energy storage across residential, C&I and grid-connected segments. The Mój Prąd programme continues to subsidise PV-plus-storage installations for households, while for larger projects, policy mechanisms increasingly support MW/MWh-scale storage through CAPEX grants, preferential financing and access to balancing and ancillary services markets.
Pedido de proyecto de 320 MWh en la República Checa subraya la tracción del mercado
AlphaESS confirmed that it has secured a 320MWh, the largest standalone energy storage project order in Czechia. The project is scheduled for delivery within the next two months, and the contract award demonstrates market confidence in the company’s system design approach and project execution framework.
De la exposición al desarrollo de proyectos
Following the Warsaw exhibition, AlphaESS stated that its priority is to support feasibility studies, technical assessments and early-stage project development with utilities, developers and industrial asset owners across Poland and Central and Eastern Europe.
