These systems are suited to large commercial and industrial facilities, large microgrids, grid‑connected assets and utility‑scale applications where performance, flexibility and reliability are critical.
Each system can be tailored to the specific requirements of the site and application. Optimal integrates proven power conversion systems (PCS) from leading suppliers such as Delta Electronics and Hitachi Energy with battery technologies from established manufacturers, including BYD, Sunwoda and others. This technology‑agnostic approach ensures the most appropriate solution is selected for each project.
Large‑scale systems can be delivered as standalone battery installations or integrated with renewable generation, using either AC‑ or DC‑coupled architectures. This makes them equally suited to new (greenfield) developments and retrofit projects, with the flexibility to participate in a wide range of grid and market services.
Advanced power conversion and control systems enable the BESS to perform functions such as energy shifting, peak shaving, demand charge reduction, frequency regulation, voltage support and microgrid operation. Intelligent control platforms optimise energy flows in real time, maximising system value, improving reliability and helping stabilise the grid.
From concept design through to integration and commissioning, Optimal provides end‑to‑end delivery of scalable, bankable large‑scale energy storage solutions for commercial, industrial and utility‑scale applications.
