IN Brief:
- Sermatec has presented a broad energy storage portfolio at Intersolar Europe 2026.
- The showcased systems include the SERLATTICE 7.04MWh liquid-cooled system, SERLATTICE 6.26MWh system, and EASYCUBE 261kWh all-in-one cabinet.
- The company also highlighted digital energy management, VPP aggregation capability, thermal runaway warning, and self-developed PCS and battery-management components.
Sermatec has presented utility-scale and commercial energy storage systems at Intersolar Europe 2026, setting out a portfolio that combines battery hardware, system integration, digital operation, and lifecycle service support.
The company showcased the SERLATTICE 7.04MWh liquid-cooled energy storage system, which is designed around high energy density and a DC-side round-trip efficiency of at least 95%. It also presented the SERLATTICE 6.26MWh energy storage system, using an integrated AC/DC architecture and supporting four-unit parallel configuration.
For commercial and industrial applications, the EASYCUBE 261kWh all-in-one cabinet is designed for plug-and-play deployment and parallel expansion. Alongside the physical systems, Sermatec displayed its Nebulos intelligent operation platform for electricity trading participation and virtual power plant aggregation.
The MOFS intelligent early-warning box is designed to provide non-destructive thermal runaway prediction two to three hours in advance. Self-developed components on show included a 430kW string liquid-cooled PCS, active balancing BMU, battery cluster controller, and battery stack management unit.
European storage procurement is increasingly focused on integrated systems rather than isolated battery containers. Storage assets now have to satisfy several requirements at once: energy capacity, power conversion performance, thermal management, safety monitoring, grid-code compliance, cyber security, market participation, asset optimisation, and long-term serviceability.
That movement is visible across the wider market, with integrated European BESS platforms and charging, storage, and site-energy systems moving storage suppliers toward broader energy-system packages. Procurement is shifting from component selection toward operational outcomes, where the value of an installation depends on coordinated operation across batteries, PCS, software, switchgear, transformers, and grid interfaces.
Liquid cooling continues to gain ground because higher energy density and larger containerised systems increase the importance of temperature control. Thermal performance affects battery life, safety, efficiency, availability, and warranty conditions. Poor thermal management can reduce usable capacity, accelerate degradation, and increase operational risk, which makes advanced warning systems and predictive diagnostics part of the core storage package.
The C&I system offer reflects another growth area. Commercial and industrial sites are increasingly considering batteries for peak shaving, tariff optimisation, solar self-consumption, backup, resilience, and participation in flexibility markets where local rules allow. A 261kWh cabinet sits below utility-scale projects but above small building-level storage, addressing sites where electrical demand, tariff exposure, and onsite generation can justify a dedicated storage asset.
VPP aggregation is also becoming more important as distributed batteries move beyond standalone site operation. Individual assets can provide local value, while aggregated fleets can participate in electricity trading, ancillary services, flexibility markets, and balancing arrangements. That requires metering, communications, dispatch capability, data reliability, and control systems able to coordinate assets without compromising site-level requirements.
Safety remains central to storage deployment. As battery systems become larger and more common in dense electrical networks, early fault detection, fire safety design, ventilation, access control, monitoring, emergency response planning, and insurer requirements all influence project delivery. Hardware specification is increasingly being assessed through operational risk and lifecycle performance, rather than nameplate capacity alone.
Sermatec’s emphasis on localised service across Central, Eastern, and Southeastern Europe reflects a maturing storage market. Storage assets have long operating lives, and their performance depends on commissioning quality, firmware management, spare parts, inspections, corrective maintenance, warranty handling, and operating data.
The company’s Intersolar presentation adds another example of storage suppliers positioning themselves as integrated energy-system providers. As Europe’s storage market grows, the strongest systems will be judged by availability, safety, degradation control, market access, and the quality of their grid behaviour over time.
