Description

Product Description

The Sungrow 150 kW PV Inverter (model SG150CX) is engineered for large‑scale commercial and industrial photovoltaic installations requiring high power, efficiency, and system flexibility. This inverter supports seven independent Maximum Power Point Trackers (MPPTs) with up to 21 PV string inputs, enabling optimal energy extraction from complex array configurations and partial shading scenarios. Its wide DC voltage range (up to 1100 V) ensures compatibility with modern high‑power PV modules. Advanced features such as intelligent PID recovery, global MPPT scanning, and AFCI 3.0 arc fault detection improve safety and maintain output performance over time. Built‑in communication interfaces support remote monitoring and diagnostics, while its rugged IP66 and C5 corrosion‑resistant enclosure makes it suitable for outdoor commercial environments. Overall, the SG150CX offers high conversion efficiency, comprehensive protection, and scalability for demanding solar energy projects.
