SUNGROW - SG125CX-P2 Inverter

The Sungrow SG125CX-P2 inverter is a 125 kVA three-phase string inverter designed for commercial and industrial photovoltaic installations. Intended for medium to high-power projects, this inverter integrates 12 independent MPPTs with 2 inputs per tracker, allowing for a flexible configuration suitable for complex roofs or installations with multiple orientations.

The recommended photovoltaic input power reaches 175 kVA , allowing for a calculated oversizing of the PV array to optimize production under real-world conditions. Each MPPT input accepts a current of 30 A , compatible with the Solar panels power greater than 500 Wp , including the latest bifacial and high-density generations.

The maximum efficiency of 98.5% and the European efficiency of 98.3% minimize conversion losses and improve the return on investment over the lifetime of the system. The extended MPPT voltage range (180-1000 V) allows for optimal adaptation to different chain configurations and seasonal variations.

IP66 protection and C5 anti-corrosion certification guarantee outdoor installation in harsh environments, including marine and industrial settings. The intelligent forced-air cooling system maintains performance even at high ambient temperatures.

Advanced diagnostic features include intelligent IV curve, string monitoring, AFCI 2.0 arc fault protection, and network fault logging for easier remote maintenance. The integrated PID recovery function allows for the regeneration of modules affected by potential-induced degradation.
