Sungrow SG40CX V112

Three-phase | 40 kW | 2 MPPT | AFCI



The SG33CX, SG40CX and SG50CX are a range of three-phase multi-MPPT string inverters from Sungrow. This system offers comprehensive monitoring integrated with Smart IV Curve Diagnose, a feature that uses current-voltage (IV) curve analysis to assess the health and performance of solar panels. By comparing actual IV curves with reference curves, it detects potential problems such as shading, degradation or faults. Smart IV Curve Diagnose enables timely maintenance and helps maximise system efficiency.

These inverters are compatible with bifacial modules rated at over 500 Wp.

SG33CX-V112: 3 MPPT, 33 kW
