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.
Dva nové velké komerční a průmyslové systémy reagující na reálné potřeby průmyslu, komerce i sítě
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.
Kompletní portfolio: od domácností až po projekty na straně sítě
In addition to the new large C&I systems, AlphaESS showcased products already deployed across different market segments.
- Rezidenční segment - řada SMILE-G3 Modulární rezidenční systémy ukládání energie s možností rozšíření až na 111,6 kWh navržené pro domácnosti kombinující fotovoltaiku a úložiště v rámci polského programu Mój Prąd. Systémy podporují vyšší vlastní spotřebu, záložní napájení a větší energetickou nezávislost uživatelů.
- Komerční a průmyslový segment - STORION-H30/H50-G3 a STORION TB125 STORION-H30/H50-G3 jsou kompaktní hybridní komerční a průmyslové systémy o výkonu 30 kW a 50 kW škálovatelné paralelně až na 500 kW a 2,4 MWh, které jsou určené pro aplikace tzv. „za elektroměrem" v menších komerčních a lehkých průmyslových provozech. STORION TB125 je komerční a průmyslový systém o výkonu 125 kW a kapacitě 261 kWh připojený na střídavé straně (AC-coupled), který podporuje paralelní provoz až 50 jednotek a umožňuje škálovatelné nasazení ve větších projektech s požadavkem na flexibilní rozšiřování kapacity.
- Velkokapacitní segment - Aster 5000 Aster 5000 je kontejnerový systém ukládání energie o kapacitě 5 MWh ve 20stopém provedení, určený k frekvenční regulaci, podpoře špičkového zatížení a integraci obnovitelných zdrojů v projektech připojených k síti.
This portfolio positions AlphaESS to support both behind-the-meter projects at industrial sites and grid-side projects led by utilities and power companies.
Podpora investic do ukládání energie v Polsku
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.
Projekt o kapacitě 320 MWh v České republice potvrzuje tržní potenciál
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.
Od výstavy k realizaci projektů
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.
