GoodWe GW6000-SDT-30 String Inverter 6kW Three-Phase 2 MPPT
The GoodWe GW6000-SDT-30 is the three-phase 6kW photovoltaic string inverter of the SDT G3 series, intended for systems without storage, from medium-large residential to small commercial. It features 2 MPPT with an input current of 22A per tracker, a maximum PV voltage of 1,100V and a wide MPPT range of 140-1,000V, which allows long strings and production starting from as low as 160V.
Maximum efficiency reaches 98.4% with a European efficiency of 97.7%; cooling is by natural convection and the IP66 protection rating allows outdoor installation, with temperatures from -30 to +60 °C. For communication, 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 disconnector and remote shutdown; AFCI arc fault detection is available on the dedicated versions.
