Sungrow, a China-based solar inverter manufacturer, has validated the resilience of its 1+X 2.0 modular inverter in Northwestern China’s Taklamakan Desert. The inverter was tested with TÜV Rheinland during a 100-day on-site trial in September 2025, facing extreme environmental conditions throughout. It was exposed to five major sandstorms over 45 days, with wind speeds above Beaufort scale 10 and visibility below 100 meters. According to Sungrow, PM10 concentrations rose above 4,000 μg/m³, but the inverter has performed without derating, maintenance, or component failure. Inspection after the test ensured no dust had entered the electronic compartment, proving effective protection against extreme desert conditions. Sungrow said durability was ensured through a triple-layer system using dual-layer mesh filtration, short airflow paths, and IP66-sealed enclosures. The inverter was also equipped with AI-driven airflow reversal that has cleared obstructions and maintained consistent performance during sandstorm exposure. Earlier this year, Sungrow has supplied SG350HX inverters for a 70 MW solar park in Simo, Finland, located near the Arctic Circle.
