The GoodWe ET 15-29.9 Series inverter is suitable for large PV projects in the residential sector and small projects in the commercial sector. The GoodWe hybrid inverter has an integrated switching device for emergency power supply. This allows the inverter to continue supplying the home with 3-phase emergency power in the event of a grid failure. The hybrid inverter is capable of black-start and can charge solar energy. The trend towards more powerful PV modules has an impact on the overall requirements for PV installations. As leaders in development, we are working to ensure that GoodWe's ET Series inverters meet the needs of high-power rooftop solar installations by facilitating backup power, reducing peak loads through peak-shaving and controlling load to increase self-consumption and reduce electricity costs. The ET series can be combined with energy storage of different capacities and brands, including GoodWe Lynx Home F.
