Dubai, U.A.E., August 25, 2025 — Sungrow, a globally leading provider of PV inverters and energy storage systems, officially launched its next-generation energy storage solution — PowerTitan 3.0 — at the 2025 MEA PV & ESS Summit in Dubai. Designed specifically for the challenging climates and operating conditions of the Middle East and Africa (MEA), PowerTitan 3.0 incorporates cutting-edge technologies in thermal management, battery design, and grid-forming capabilities, establishing a new industry benchmark for efficiency, safety, and reliability.
The PowerTitan 3.0 is an AC liquid-cooled energy storage system that supports 2–4 hours of operation. In a 20-foot configuration, it integrates a 1.72 MW power conversion system (PCS) with 6.9 MWh battery capacity, enabling a single block to achieve 6.9 MW/27.6 MWh for 4-hour duration.
Equipped with high-temperature-resistant silicon carbide (SiC) devices, the PCS achieves up to 99.3% efficiency and maintains full-power output at 55°C without derating. This ensures long-term reliability, safety, and profitability even under extreme heat. Overall system conversion efficiency reaches 92%, setting a new standard in large-scale energy storage system (ESS) design.
To support increasing power plant capacities, PowerTitan 3.0 utilizes Sungrow’s innovative stacked energy storage cells (684Ah and 661Ah). This design eliminates corner stress found in traditional wound cells, reduces internal resistance, and minimizes risks such as lithium plating, internal short circuits, and thermal runaway.
The battery structure, pioneered by Sungrow, positions exhaust vents and electrode tabs at opposite ends, enhancing safety even in venting scenarios. Each battery pack includes a dedicated exhaust channel, and thermal insulation layers between cells prevent propagation. Additionally, the AI Battery Management 2.0 system offers over 95% accuracy in lithium plating diagnosis and more than 99% precision in thermal risk warnings, enabling proactive and reliable risk prevention.
With an optimized pack design, energy density reaches 467 kWh/m². A 15 cm back-to-back layout allows a 1 GWh plant to occupy only 7,270 m² — a 22% reduction compared to the previous generation — significantly reducing construction work and capital expenditure.
Leveraging Sungrow’s AC-DC integration, PowerTitan 3.0 assigns one PCS per rack to eliminate SOC imbalances between racks. With an SOC estimation error of less than 3% and automated calibration, balancing is maintained at both rack and block levels. This innovation increases discharged energy by up to 8% over the system’s lifecycle, maximizing returns for operators.
The extreme climate in MEA makes auxiliary power consumption a critical cost factor for energy storage plants. Unlike traditional designs that recycle hot air, PowerTitan 3.0 employs a top-only exhaust design for both the ESS and medium-voltage switchgear, preventing heat recirculation. Large-scale simulations show that at 55°C, conventional systems experience an 8°C rise in air intake temperature, while Sungrow’s design limits this increase to just 1.53°C — reducing auxiliary power consumption by 9%.
With AI Bionic Thermal Balance 2.0, the system predicts weather and operational conditions to enable flexible compressor and fan control with ±1°C precision, cutting auxiliary power use by an additional 10%.
Featuring IP55 protection and C5 corrosion resistance, PowerTitan 3.0 delivers reliable performance in deserts, coastal areas, and sandstorm-prone regions. Sungrow has further established global safety benchmarks through large-scale burn tests on its PowerTitan 1.0 and 2.0 systems, demonstrating zero fire propagation under extreme conditions.
Energy storage plays a vital role in absorbing fluctuating renewable power generation while supporting grid stability. PowerTitan 3.0 incorporates Sungrow’s advanced grid-forming capabilities, proven in landmark projects such as Saudi Arabia’s NEOM City — the world’s largest multi-energy system integrating solar, wind, storage, and hydrogen. With a solar-to-storage ratio exceeding 3:1, the system offers millisecond power response, microsecond voltage control, and GW-scale black start capabilities, strengthening grid stability in markets with high renewable penetration.
With over 15 GWh of ESS projects delivered across the MEA region, Sungrow has built a strong local presence over more than a decade. The launch of PowerTitan 3.0, along with the company’s 1+X 2.0 Modular Inverter, underscores Sungrow’s ongoing commitment to advancing the MEA’s energy transition through innovation, resilience, and sustainability.
