The energy storage specialist Sermatec used its Intersolar Europe 2026 presence to lay out a complete, vertically integrated offering that spans core components, system integration and cloud-based operation. On the show floor the company emphasized how hardware advances and digital orchestration combine to cut lifecycle costs, raise reliability and enable participation in energy markets.
Alongside product demonstrations Sermatec announced new international cooperation agreements and hosted partners at an evening event on June 24. The portfolio showcased solutions for utility-scale installations as well as commercial and industrial (C&I) deployments, underpinned by a localized service and lifecycle support model for Central, Eastern and Southeast Europe.
Utility-scale systems: SERLATTICE performance and configurations
Sermatec highlighted two primary utility-class platforms. The flagship liquid-cooled system, SERLATTICE is offered in a 7.04 MWh configuration and achieves an industry-leading volumetric energy density of 477 kWh/m². That compact footprint is paired with a direct-current round-trip efficiency (RTE) of ≥95% on the DC side, delivering a high energy conversion performance that reduces both space and energy losses.
A second variant, the SERLATTICE 6.26 MWh model, incorporates an integrated AC/DC architecture that raises total system efficiency by roughly 2 percentage points. The 6.26 MWh unit is designed for modular expansion: up to four systems can be paralleled to scale capacity. Built-in intelligent thermal controls further cut auxiliary power needs by about 25% lowering operating expenditures across the unit life.
C&I and plug-and-play options: EASYCUBE and fleet orchestration
For commercial and industrial customers Sermatec showcased the EASYCUBE a 261 kWh all-in-one energy storage cabinet. The product targets fast deployments with plug-and-play installation and supports parallel expansion to match changing load profiles. Typical use cases include peak shaving, improved renewable self-consumption and bolstering resilience for critical processes.
Beyond physical systems Sermatec demonstrated its software layer. The Nebulos Intelligent Operation Platform connects devices to cloud services, enabling market participation, aggregated bidding and formation of a virtual power plant (VPP) to monetize flexibility. Complementing Nebulos, the MOFS Intelligent Early Warning Box provides non-destructive prediction of thermal anomalies up to two to three hours in advance enabling proactive interventions that raise fleet safety.
Components, field track record and localized service
The booth also featured several in-house hardware components that illustrate Sermatec’s internal integration capability: a liquid-cooled 430 kW string PCS the 104-string active balancing BMU the Battery Cluster Controller (BCC) and the Battery Stack Management Unit (BSMU). These elements are intended to work together to improve diagnostics, control and operational availability.
Sermatec pointed to a growing set of international projects as proof points. In Bulgaria a deployed system is optimized to extract value from spot-market arbitrage and ancillary services. Installations in Croatia and the Czech Republic demonstrated resilience to low winter temperatures and variable industrial loading, while Spanish projects validated protection schemes and thermal management under high humidity and coastal salt exposure.
To support long-term ownership the company described a regional service network that bundles extended warranties, performance guarantees, preventive maintenance, corrective repairs and operational reporting. This localized model aims to make lifecycle costs transparent and to deliver predictable outcomes for customers across multiple countries.
Partner engagement and industry outreach
Sermatec reinforced commercial ties during its annual Partner Night on June 24 gathering key collaborators from across Europe. The evening combined executive presentations, product briefings and discussions about after-sales service frameworks, creating a setting for strengthening distribution channels and exploring regional deployment opportunities.
At Intersolar Europe 2026 Sermatec positioned itself as a company that merges hardware innovation with software orchestration to enable flexible revenue streams, resilient operations and lower lifecycle costs. The exhibit underscored the company’s strategy of offering vertically integrated systems from cell management and power conversion to cloud-based aggregation and predictive safety tools.
