Specifications
Product Description
The Sungrow SG125CX-P2 Three-Phase Solar Inverter | 125 kW is a multi-MPPT platform for 1000 Vdc systems designed for large-scale commercial and industrial projects. With 12 independent MPPTs (24 strings in total), it reduces losses due to mismatches and shading and allows string design by roof section, orientation, or module type. The IP66 enclosure, C5 corrosion resistance, SPD DC Type I+II and SPD AC Type II protection, along with AFCI 2.0 and PID recovery, enhance safety and availability. Intelligent I-V curve diagnostics and full integration with iSolarCloud enable predictive O&M, shortening intervention times and reducing costs.
Main Features
- Nominal AC power 125 kW and apparent power 125 kVA; max./nominal AC current ~181 A at 400 V.
- 1000 Vdc platform with max. input voltage 1100 V; MPPT range 180–1000 V (Vnom 600 V; startup 180/200 V).
- 12 MPPT / 24 strings (2 per MPPT); max. input current 360 A (30 A×12) and max. Isc 480 A (40 A×12).
- Max. efficiency 98.5% (European 98.3%) and night consumption <5 W.
- Comprehensive safety: AFCI 2.0, anti-islanding, ground fault, DC reversal, PID recovery, SPD DC Type I+II and SPD AC Type II.
- Connectivity and O&M: RS485 standard; optional WLAN/Ethernet; app with Bluetooth; Smart IV Curve and iSolarCloud with OTA updates.
Advantages or Benefits
- Higher annual yield thanks to 12 MPPTs that optimize each generator area and minimize losses from shading or module mismatch.
- Superior availability due to active protections (AFCI 2.0 and SPD I+II/II) and proactive string-level diagnostics.
- Flexible and robust installation: AC up to 240 mm² Al/Cu, drawer-type sealing plate, and DC connections MC4-Evo2 (≤6 mm²).
- Reliability outdoors and in coastal areas with IP66/C5 and intelligent forced cooling that maintains power in hot climates.
- Reduced O&M costs due to 24/7 monitoring, alarms, network logs, and remote maintenance.
Purpose or Applications
Designed for three-phase self-consumption in industrial warehouses, logistics, agri-food, shopping centers, photovoltaic car parks, and rooftop plants. Ideal when export control, reactive power management, and compatibility with high-current modules (500 W+) are required.
