Sungrow 125CX On-grid 3 Phase Inverter (SG125CX-P2)

The Sungrow 125CX On-grid 3 Phase Inverter (SG125CX-P2) is a multi-MPPT string inverter designed for large commercial and utility-scale 1000 Vdc PV systems, delivering 125 kVA rated AC output power (181.1 A max current) at 230/400 V with 98.5% maximum efficiency and 98.3% European efficiency. Featuring 12 independent MPP trackers (2 strings each), 175 kW recommended max PV input (360 A total, 20 A per connector), 180–1000 V MPP range (1100 V max, 600 V rated), and dynamic shading optimization, it supports high-power 500W+ modules with smart forced air cooling in an IP66/C5 corrosion-resistant enclosure weighing 87 kg (1020 × 795 × 360 mm). Advanced safety includes DC Type I+II/AC Type II surge protection, AFCI 2.0 arc detection, PID recovery, ground fault monitoring, DC reverse polarity protection, leakage current protection, an integrated DC switch, and PV string-level monitoring compliant with IEC 62109, VDE-AR-N 4105, G99, and global grid codes. Smart O&M features IV curve diagnosis, grid fault recording, Q at night, LVRT/HVRT, active/reactive power control, and connectivity via RS485 (optional WLAN/Ethernet), Bluetooth/APP, LED display for remote management with <5 W night consumption operating from -30°C to +60°C up to 4000 m altitude. The SG125CX-P2 uses transformerless topology with Evo2 DC (6 mm² max) and OT/DT AC terminals (240 mm² Al compatible) for cost-effective installation.
