Sungrow has unveiled two groundbreaking products during a PV&ESS summit in Dubai, with over 300 partners and industry experts witnessing the launch of the 1+X 2.0 modular inverter and PowerTitan 3.0 ESS.
Both products feature the industry’s leading safety and durability applications to ensure stable, high-efficiency operation in the MEA’s extreme conditions. The 1+X 2.0 features a scalable block design ranging from 780kW to 9.375MW, with a front-in, rear-out cooling design ensuring stable full-load operation even at 52°C. The PowerTitan 3.0 boasts the industry’s first large-scale fully liquid-cooled Silicon Carbide Power Conversion System (SiC PCS), delivering exceptional efficiency (up to 99.3%) and consistent full-power output even at 55°C, raising the overall energy storage system conversion efficiency to 92%.
The 1+X 2.0 is engineered to be robust in harsh conditions, including high temperatures and sandstorm areas. It features high-performance components, efficient heat exchangers and built-in safety margins across all critical parts. Its unique dual-duct cooling system separates hot and cold airflow to eliminate thermal interference, while redundant thermal design ensures continuous full-load operation even at temperatures up to 52°C. The IP66-rated fully sealed design, high-level protective materials and self-cleaning air duct system ensure the product maintains clean internal components and high reliability. It has successfully withstood 100 days of real-world sandstorm testing, emerging dust-free inside and maintaining stable power output.
Its split modular design allows quick field replacement of critical components, reducing O&M time to just one hour per module. Equipped with an intelligent diagnostics function, it also delivers real-time fault detection to speed up repairs and minimize manual intervention.
With DC faults potentially resulting in short-circuit, arcing or even fire, the inverter, equipped with an Intelligent DC-Side Safety Management System, can disconnect faulty circuits within 40 milliseconds to prevent such risks when an arc fault is detected, simultaneously shutting down related combiner boxes. Additionally, a high-precision temperature sensor network monitors inverter terminal in real-time, disconnecting circuits immediately upon detecting overheating to further enhance fire safety.
In response to customer needs in the MEA, Sungrow has introduced the PowerTitan 3.0 AC liquid-cooled energy storage system, supporting 2–4 hours of operation. The 20 ft configuration integrates a 1.72 MW PCS with 6.9 MWh batteries, delivering a 4-hour system where a single block reaches 6.9 MW/27.6 MWh. Equipped with high-temperature-resistant SiC devices in the new PCS, the PCS achieves up to 99.3% efficiency and sustains full-power operation without derating at 55°C, ensuring long-term safety, reliability and profitability.
PowerTitan 3.0 adopts a top-only exhaust design for both ESS and MVS, preventing hot and cold air from mixing. In GW-level simulations at 55°C, traditional setups showed an 8°C air-inlet rise, while Sungrow limited it to just 1.53°C, reducing auxiliary power by 9%. Its AI Bionic Thermal Balance 2.0 further predicts weather and operational plans, enabling flexible compressor and fan control to achieve ±1°C precision in temperature regulation and reduce auxiliary power consumption by an additional 10%.
For projects demanding large capacity and cost-effectiveness, the product comes with Sungrow’s third-generation stacked 684Ah and 661Ah energy storage cells. Through stacked cells and optimized pack design, energy density reaches 467 kWh/㎡. With a 15 cm back-to-back layout, a 1 GWh plant needs only 7,270 ㎡—22% less than the previous generation—significantly reducing construction work and lowering CAPEX.
Leveraging Sungrow’s AC-DC integration, PowerTitan 3.0 assigns one PCS per rack to eliminate SOC imbalance and the “barrel effect” inside cabinets. With an SOC estimation error of less than 3% and automated calibration, balancing is extended to both rack and block levels. This ensures up to 8% more discharged energy over the system’s lifetime, maximizing returns for plant operators.
With the MEA region rapidly advancing its power infrastructure to handle growing renewable energy integration, advanced technologies including microgrids, BMS and digital substations are being deployed to maintain flexibility and stability. Within this dynamic context, grid-forming technology is emerging as a critical enabler of resilient, renewables-rich power systems.
With over 20 years of grid-forming experience, Sungrow showcased at the event its core grid-forming capabilities – a vertically integrated holistic solution, enhanced DC safety features, a wide operating SCR range, a full-stack simulation platform and parallel PCS black start (30-level). The company has deployed more than 15 GWh of grid-forming projects globally, with successful validation already achieved across numerous projects in the MEA region.
According to the latest data for the MEA market, Sungrow has delivered over 25 GW of PV inverters and more than 15 GWh of ESS projects. The company currently operates 6 regional business offices with 200 professionals, supported by 14 warehouses and over 20 authorized service partners.
VP Thompson Meng commented: “With abundant natural resources and strong energy transition policies, MEA has become a key growth market for the global solar and energy storage industries. Sungrow has enhanced technologies, including AC block design, high-level dust protection and DC safety features to address local needs. Looking ahead, Sungrow remains committed to delivering not just competitive products, but superior quality, safety, lifecycle management and maximum ROI to accelerate the integration of renewable energy across the region.”
