To guarantee 24/7 power security for high-demand research labs and critical university infrastructure, we engineered and installed a comprehensive, high-voltage off-grid solar system. This solution integrates a robust 60 kWh high-voltage battery storage system for substantial energy reserves and a powerful 75 kW central inverter. Fueled by a total high-efficiency solar capacity of 26.88 kWp, this system allows the university campus to optimize energy resilience and maintain seamless, continuous operations regardless of grid stability.
