The GoodWe ET Series (GW80K-ET-G10 and GW100K-ET-G10) is a three-phase hybrid inverter for commercial and industrial solar-plus-storage, covering 80 to 100 kW in a DC-coupled design. It carries 8 MPPTs with 200% PV oversizing and up to 21A per string (2 strings per MPPT), plus dual independent HV battery inputs supporting up to 220A total for larger, more flexible storage builds. Efficiency reaches 98.1% max (97.7% European, 98.2% battery-to-AC), and it ships with a GM330 smart meter, RS485 + WiFi + Bluetooth communication, and the WIFI/LAN Kit-20 module (CAN to the BMS). Protection is comprehensive and integrated — AFCI, integrated DC switch, Type I+II SPD on the DC side and Type II on AC, plus PV insulation and string-current monitoring, residual-current monitoring, reverse-polarity protection on both PV and battery, and anti-islanding. It is rated IP66 with C4 anti-corrosion and a −35 to +60 °C operating range, wall-mounted at 97 kg.
