Sungrow 110kW 3 Phase 9 MPPT With WiFi, DC Cover, DC Switch Built-in (P2 Version)

Sungrow SG110CX-P2 110kW Three Phase 12 MPPT Commercial String Inverter

The Sungrow SG110CX-P2 is a high-performance 110kW three-phase commercial string inverter engineered for large rooftop, commercial and industrial solar installations. Combining high power density, flexible array design, advanced safety features and intelligent operations and maintenance, it helps maximise energy yield while reducing project installation and operating costs.

With 12 independent MPPTs and support for up to 24 PV strings, the SG110CX-P2 is ideal for complex commercial rooftops with multiple orientations, varying shading conditions or diverse array configurations. It supports up to 154kW recommended PV input, delivers 110kW rated AC output, and achieves up to 98.5% maximum efficiencyfor outstanding project performance.

Designed for demanding Australian environments, the SG110CX-P2 features an IP66-rated enclosure, C5 anti-corrosion protection, smart forced-air cooling, integrated surge protection and AFCI 2.0 arc-fault protection. Smart IV curve diagnosis, grid-fault recording and optional WLAN / Ethernet connectivity support efficient remote monitoring and maintenance across commercial solar portfolios.
