GoodWe 40kW SDT G3 3Ph String Inverter - 4 MPPTs, DC & AFCI
The SDT G3 25–40 kW series is purpose-built for three-phase commercial and industrial PV systems using modern high-power modules. It accepts high input currents, supports generous DC oversizing and delivers quiet, reliable operation thanks to its fanless, IP66 design.
Optional Type II SPDs on both AC and DC sides, together with Arc Fault Circuit Interrupter 3.0 (AFCI 3.0), raise site safety by detecting arc faults, sending alarms via monitoring and shutting the inverter down when needed.
Note: G99 Certificate pending
