Sirea and Zetatech form joint venture Enexya to develop and market LFP battery energy storage systems in Europe

Type: Partnership · Technology: Storage · Country: France · Announced: 2026-06-04

French energy management specialist Sirea and Chinese battery manufacturer Zetatech established a joint venture named Enexya to develop and commercialize lithium iron phosphate (LFP) battery energy storage systems (BESS) across Europe. The new entity will combine Zetatech’s LFP battery cells produced in China by its subsidiary Sinotech with Sirea’s energy management system (EMS) developed and assembled in France, targeting industrial, commercial, and large-scale applications. Enexya’s modular product lineup includes three models: the 96 kWh 'qubM' for small tertiary sites and light industry, the up to 2 MWh 'qubL' for large industrial and commercial installations, and the 2.3 MWh extensible 'qubX' container for renewable energy parks and grid services. The systems operate autonomously or integrate with photovoltaic installations to optimize energy costs and grid services. Sirea retains control over EMS algorithm development, automation manufacturing, and final integration in France to ensure GDPR compliance and European cybersecurity standards.
