GoodWe GW30K-SDT-30 String Inverter 30 kW Three-Phase 2 MPPT
The GoodWe GW30K-SDT-30 is the three-phase photovoltaic string inverter of 30 kW from the SDT G3 series, intended for systems without storage, from medium-to-large residential up to small commercial. It has 2 MPPTs with an input current of 42 / 32 A per tracker, a maximum PV voltage of 1,100 V and a wide MPPT range of 140-1,000 V, which allows long strings and starts production from as little as 160 V.
Maximum efficiency reaches 98.6% with a European efficiency of 98.3%; cooling is by smart fan cooling and the IP66 protection rating allows outdoor installation, with temperatures from -30 to +60 °C. On the communication side, RS485, Wi-Fi, LAN and Bluetooth (with optional 4G) and the Modbus-RTU (SunSpec) and Modbus-TCP protocols are available. Protections include string and insulation monitoring, residual current control, anti-islanding, DC switch and remote shutdown; AFCI arc fault detection is available on the dedicated versions.
