GoodWe GW50KSDT-C30 AFCI

The GoodWe SDT G3 50 kW combines 180% PV oversizing with C&I-grade safety. High current input — 40 A per tracker, 21 A per string — connects today's high-power modules without clipping, 8 strings across 4 MPPTs handle split-orientation roofs, and the oversizing headroom keeps output at 50 kW even in low-light months. Integrated Shadow Scanning recovers yield on partially shaded strings, while AI-driven AFCI 3.0 detects DC arc faults, alarms through monitoring and shuts down instantly; Type II surge protection on both sides, remote shutdown and string-level monitoring are standard, optional PID recovery protects modules long-term. IP66 and −30 °C operation handle Baltic weather, and SunSpec-compliant Modbus RTU/TCP plus SEMS cover monitoring and third-party control — from a BNEF Tier 1 manufacturer with 100 GW installed worldwide, in a 33 kg body that's light for the 50 kW class

The GoodWe SDT G3 50 kW (GW50K-SDT-C30) is a three-phase string inverter for C&I rooftops with 4 MPPTs, two strings each. Every MPPT takes 40 A (21 A per string) across a wide 140–1000 V window (max. 1100 V), with peak efficiency of 98.7% (98.0% European). Protection comes integrated — AFCI 3.0 arc-fault protection, Shadow Scanning, string current monitoring, insulation and residual current detection, anti-islanding, DC switch, Type II surge protection on DC and AC — with PID recovery optional. IP66, −30 to +60 °C, under 50 dB, 33 kg; RS485, WiFi + LAN + Bluetooth, Modbus RTU (SunSpec compliant) and Modbus TCP.
