Sunlight Group Expands Global Maritime Footprint with Lehmann Marine Battery Production in Xanthi
New automated production line for Lehmann Marine battery systems now fully operational, with annual capacity of up to 300 MWh
Athens, 10 September 2026 – Sunlight Group is positioning Xanthi as a key production hub for advanced battery systems serving the global maritime industry, with a new, dedicated and automated production and assembly line for its subsidiary, Lehmann Marine, now fully operational. Through this new activity, Sunlight Group, a member of Olympia Group and a leading company in integrated and innovative energy storage technologies, is further strengthening its presence in the growing maritime electrification market.
The launch of the new production line marks another strategic step in Lehmann Marine’s growth, while leveraging Sunlight Group’s capabilities in large-scale industrial battery manufacturing in Greece. Following the successful assembly and quality control of the first 82 CUBE battery units, production is now fully operational, targeting an annual capacity of up to 300 MWh for maritime applications, with the option to add further production lines in the future.
The new production model combines Sunlight Group’s long-standing expertise and capabilities in large-scale industrial battery manufacturing with Lehmann Marine’s specialization in the sale, installation and maintenance of energy storage systems for the maritime sector. Automated assembly and product preparation take place in Xanthi, while the final Factory Acceptance Test (FAT), conducted in the presence of the customer, is carried out at Lehmann Marine’s facilities in Hamburg, Germany.
Through this model, Sunlight Group combines in-depth knowledge of the market and customer needs with demanding, large-scale manufacturing capabilities for high-performance applications. The aim is to establish an integrated European production chain for advanced maritime battery systems, delivering cutting-edge technology across the entire value chain, from design and production to installation and service.
Lampros Bisalas, CEO of Sunlight Group, commented: “At Sunlight Group, we invest with a long-term perspective in technologies, production capabilities and specialized expertise that enable us to expand into new markets and applications with strong growth potential. With Lehmann Marine as part of our Group ecosystem, we are leveraging significant synergies, combining its expertise in advanced maritime battery systems with Sunlight’s industrial scale and manufacturing know-how.
“At the same time, we are building on our strong industrial base in Greece, contributing to the transition towards cleaner and more efficient maritime transportation, while supporting employment growth in border regions through highly skilled, high-value jobs.”
As the maritime industry accelerates its transition towards electrification and lower-emission solutions, the new production capacity in Xanthi enables Lehmann Marine to respond at greater scale to growing demand for certified LFP systems. At the same time, production in Xanthi expands the export footprint of Greek industrial activity into a rapidly growing international sector. Manufacturing within Europe also reduces exposure to disruptions in global supply chains and helps shorten project lead times.
