Assistant Manager – Product Application Sungrow SAVEK DUBEY Q The PowerTitan 2.0 has been gaining global traction for utility-scale storage. Could you explain the key techno- logical innovations behind this solution and how it improves efficiency and performance? Savek Dubey: The PowerTitan 2.0 stems from a combina- tion of system-level integration, thermal management, and grid-forming intelligence. These are three areas where it sig- nificantly advances to support utility-scale storage perfor - mance. First, the innovation lies in the fully integrated AC block de - sign, where battery modules (rack) and the power conversion system (PCS) are built within a single containerised solution. This architecture reduces energy losses associated with long DC cabling and enables each battery rack to operate inde - pendently via string-type PCS control. As a result, the system achieves over 7–8 percent higher lifetime discharge capacity and significantly lowers fault propagation, enhancing both reliability and usable energy output. Another key breakthrough is its cell-to-grid (C2G) energy con - version approach, which streamlines the DC-to-AC process. This contributes to a round-trip efficiency of around 89.5 percent, which is an improvement over conventional systems by simplifying system architecture and reducing conversion losses over DC cables. The thermal management system employs full liquid cooling across both battery packs and PCS, ensuring uniform heat dissipation and maintaining a temperature differential of just ~2.5°C across cells. This tight thermal control not only improves charge/discharge efficiency but also extends system lifespan to around 20 years. In addition, the platform integrates advanced grid-forming capabilities through its ‘Stem Cell Grid Tech’. This enables features such as fast voltage and frequency response, seam - less transition during grid disturbances, and even black-start capability. These functions are increasingly critical for grids with high renewable penetration, where stability and power quality must be actively managed. Finally, its modular, high-density design – packing up to 5 MWh in a 20-foot container – improves land use efficiency and accelerates deployment through factory pre-integration. This reduces installation time, lowers balance-of-plant costs, and enhances scalability for large projects. Q Utility-scale battery energy storage systems are expand- ing rapidly worldwide. What key trends are driving the demand for BESS solutions in India? Savek Dubey: The rapid growth of utility-scale battery en - ergy storage systems (BESS) is being driven by a powerful combination of energy transition goals, grid challenges, and improving economics in India. One of the biggest drivers is the accelerating shift toward re- newable energy. As solar and wind capacity expand, the need to store intermittent energy and deliver it reliably becomes critical. In India, for example, renewable capacity is expected S ungrow’s strategy is to combine local partnerships, global expansion, and continuous innovation, position - ing itself not just as a technology provider but as a long- term partner in building large-scale, reliable energy storage ecosystems in India and worldwide, said Savek Dubey, As- sistant Manager - Product Application, Sungrow, in an in- terview with Energetica India. 24 energetica INDIA- Mar-Apr_2026 INTERVIEW
