Description
Three-Phase Sungrow SG125CX-P3 Inverter
Multi-MPPT string inverter for 1,000 Vdc photovoltaic systems
The Sungrow SG125CX-P3 three-phase inverter is a 125 kW solution designed for commercial and industrial photovoltaic installations and large-scale solar plants. It features 10 independent MPPTs, supports up to 198 kWp of recommended PV input power and achieves a maximum efficiency of 98.5%.
Its high input capacity, with up to 40 A per MPPT and 30 A per DC connector, makes it suitable for modern high-power, high-current PV modules. It also features global MPPT scanning, intelligent PID recovery and individual string current monitoring.
The SG125CX-P3 enhances safety and maintenance through AFCI 3.0+, active fault identification, intelligent I-V curve diagnosis and module-level insulation fault location. Its IP66 protection rating, C5 corrosion resistance and smart forced-air cooling system make it suitable for installation under a wide range of environmental conditions.
