Energy for the future – about Sunlight Group
Sunlight Group is a globally operating energy technology company headquartered in Athens, Greece. The company develops and manufactures state-of-the-art energy storage systems for industrial, commercial and grid-scale applications – based on lead-acid and lithium-ion technology (including LFP). Manufacturing takes place in the company's own plants, including the Industrial Complex in Xanthi (capacity 9 GWh/year), the lithium battery plant in Greensboro (North Carolina, USA) and the Triathlon subsidiary in Glauchau, Germany. With its own recycling facilities in Komotini, Kilkis, Xanthi, Glauchau and Greensboro, the company closes the material loop for lead-acid and lithium-ion batteries. The portfolio covers battery systems for intralogistics, cold chain, airport ground handling, electromobility, marine, rail, data centers and defense, complemented by chargers, accessories, IoT solutions and a comprehensive service network. With more than 3,500 employees, 35+ locations worldwide and supply to more than 115 countries, Sunlight is one of the leading manufacturers of industrial batteries and energy storage systems in Europe.
