C&I Energy Storage Solutions-Our Commercial & Industrial (C&I) Energy Storage systems are engineered to provide robust, scalable, and cost-effective energy management solutions for businesses and large-scale industrial applications. Designed to integrate seamlessly with renewable energy sources and existing power systems, our solutions help optimize energy usage, reduce costs, and promote sustainability.

C&I (Commercial and Industrial) energy storage system works similarly to a residential energy storage system but on a larger scale to accommodate the higher energy demands of commercial and industrial facilities. The system can be charged with electricity generated from renewable sources like solar panels or wind turbines or from the grid during off-peak hours, with a battery management system (BMS) or charge controller ensuring the safety and efficiency. The charged batteries store the electrical energy as chemical energy, and then the inverter converts the direct current (DC) electricity stored in the batteries into alternating current (AC) electricity to power the facility's equipment and devices. A C&I energy storage system often includes advanced monitoring and control features that allow facility managers to track energy generation, storage, and consumption, helping optimize energy usage and reduce costs. The facilities with energy storage systems can also interact with the grid, participating in demand response programs, providing grid services, and exporting excess renewable energy back to the grid.
