The expansion marks a strategic milestone for the company. Following the assembly and quality verification of the first 82 CUBE battery modules, the new Xanthi line is now fully operational. Modules will be shipped weekly from Greece to Lehmann Marineís recently expanded headquarters in Hittfeld, Germany, for final system integration, testing, and distribution. Once fully ramped up, the specific automated line is targeted to produce up to 300MWh annually for maritime applications, with the option for additional production lines to be added in the future.

"With Sunlight Group, we have a strong industrial partner whose manufacturing scale perfectly complements our specialised engineering capabilities," said Alexander Lehmann, Managing Director of Lehmann Marine. "Together, we have created the ideal platform to reliably meet growing customer demand for safe, high-performance maritime battery systems while securing supply chain stability."

Labros Bisalas, CEO of Sunlight Group, stated, "Our role at Sunlight Group is to elevate Lehmann Marine´s leading marine capabilities with decades of industrial battery manufacturing experience at large scale and with significant vertical integration in critical components. This integrated European model gives our global maritime partners an unmatched advantage: cutting-edge technology, automated mass production, and stability of supply during global supply chain disruptions."

Strategic Value for the Maritime Sector

To meet tightening environmental mandates, the maritime industry requires rapid, secure access to certified LFP battery systems. The Xanthi expansion combines high-volume industrial-scale production to cut project lead times with European supply chain security that insulates clients from global trade disruptions. Every battery system undergoes rigorous dual-stage quality assurance, starting with automated testing in Xanthi and concluding with final commissioning in Hittfeld, ensuring maximum safety and reliability at sea.
