Industrial battery manufacturer scaling lithium tech and energy storage systems

Renewable Energy Semiconductor Manufacturing Kifisiá, Attiki 1,001–5,000 employees Founded 1991 Privately Held

Sunlight Group manufactures lead-acid and lithium-ion batteries for industrial, mobility, and renewable energy storage across five continents. The tech stack reveals a manufacturing-first operation: heavy investment in PLC/SCADA/CNC systems paired with SAP ERP and plant maintenance modules, plus emerging ML/AI tooling (TensorFlow, PyTorch, scikit-learn) applied to load forecasting and grid optimization. The hiring mix is production-weighted (manufacturing and engineering dominate), with deliberate focus on preventive maintenance, component sourcing, and sales function buildout — signaling a shift from pure manufacturing toward commercial scaling.
