GoodWe 125kW GT 3Ph String Inverter - AFCI, Type I+II SPD DC


Engineered for modern C&I solar, the GT Series combines high power density with smart thermal design to deliver strong output, solid reliability and quicker payback.

Multiple MPPTs and high string current (21A) support today’s large-format, high-power modules, while robust surge protection and weatherproofing keep systems running in tough environments. The result is a compact, installer-friendly inverter platform that simplifies commissioning and helps maximise lifetime energy yield on rooftops, carports and small ground-mounts.


KEY FEATURES:

  • 10 MPPTs
  • Type I+II SPD DC
  • Up to 187.5 kW max DC input (150% DC oversizing)
  • Lower CAPEX & OPEX: high power density with up to 137kW maximum power for low voltage grid applications (400V). 
  • AFCI for enhanced arc-fault mitigation.
  • Up to 21 A per string, compatible with high-current PV modules
  • Max PV input voltage: 1100 V
  • European efficiency: up to 98.4%
  • IP66 enclosure with C4 corrosion protection (optional C5) for coastal/industrial sites.
  • Communication: RS485, WiFi or 4G or PLC(Optional)
  • String-level monitoring and remote portal access for fast diagnostics via GoodWe platforms
  • Typical applications: large commercial rooftops (warehouses, distribution centres, schools, hospitals), carports/canopies, and small–medium ground-mount or community solar
  • Warranty: 5 Years
