Sungrow unveiled its latest innovation - the 1+X 2.0 Modular Inverter - during the 2025 MEA PV & ESS Summit held in Dubai. Tailored to the harsh desert environment in MEA, the new inverter is designed for stable full-load operation at 52degC, with a scalable block design from 780kW up to 9.375MW. Featuring significant upgrades in system availability, safety, and grid adaptability, the 1+X 2. 0 sets new benchmarks for utility-scale solar projects in the MEA.

Middle Eastern summer can exceed 52degC, and utility-scale PV plants act as massive heat sources, driving internal temperatures even higher, with notable differences across PV array blocks within the same plant. Traditional inverters often suffer derating or shortened lifespans under such conditions. Sungrow's 1+X 2.0 addresses this challenge with 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, eliminating thermal interference, while redundant thermal design ensures continuous full-power operation. The inverter has passed high-temperature and irradiation tests, and wind-direction disturbance tests, proving its durability in desert heat. With these innovations, the 1+X2.0 delivers stable, full-power performance even at 52degC.

IP66 Protection: Resistant to Sandstorms: With a fully sealed design, high-level protective materials, and a self-cleaning air duct system, the 1+X 2., keeps internal components clean even during prolonged sandstorms. The inverter has successfully endured 100 days of onsite sandstorm testing including 45 days of severe sandstorm testing including 45 days the severe sandstorm, emerging dust-free inside and maintaining stable power output-- demonstrating reliability under the Middle East's year-round sand and dust conditions. Simultaneously, via inverter cluster control technology, other combiner boxes in the same block are synchronously shut down in tandem to prevent any fault contribution. Terminal Overheating Protection System: A high-precision temperature sensor network is deployed to monitor inverter terminal temperatures in real-time.

Upon detecting abnormal temperatures, the corresponding circuit is immediately disconnected, eliminating fire risks caused by poor electrical contact. Pioneering the pyro fuse protection Accurately detects 15 fault types (short-circuit, arc, overload, etc.) and disconnects within 2ms, protecting the equipment from damage. Optimizing LCOE: More Power, Lower Cost: Microgrid Capability: Diesel-Free Commissioning: 1+X Modular Inverter 2.0 can form a microgrid within or across blocks, providing power for construction and commissioning without diesel generators.

For example, a 1GW project in the Middle East with this technology achieved grid connection 30 days ahead of schedule, generating 2.9 million USD in additional revenue, significantly reducing the Levelized Cost of Energy (LCOE). Enhanced System Economics: Larger block designs, longer string access, and MPLC communication reduce initial investment. For example, a 1 GW solar plant can save up to USD 3.24 million in CAPEX.

Combined with intelligent diagnostics function, simplified O&M and night-time medium voltage disconnection, the solution also significantly lowers OPEX. Grid-Forming Technology: Enabling Solar-Plus-Storage Future: Equipped with Sungrow's solar grid-forming technology, the inverter ensures seamless operation in both strong and weak grids. 1+X Modular In Verter 2.0 is compatible with both DC- and AC-coupled solar-plus-storage solutions, further relieving grid absorption stress.

The DC-coupled solution with this new product is more efficient and cost-effective, enabling an initial investment reduction of over 10% and system conversion efficiency enhanced by 5% compared to traditional AC-coupled solutions. The solution enables 100% grid-coupled solutions enables 100% grid-forming capability based on AC capacity, making it a solar-plus-storage generator. A Decade of Commitment to the MEA.
