Goodwe GW20K-ET 20kW Three-phase Hybrid Inverter

Goodwe GW20K-ET 20kW Three-phase Hybrid Inverter

GoodWe GW20K-ET high voltage hybrid inverter from the ET series with emergency power output. The 20kW three-phase hybrid inverter is suitable for large PV projects in the residential sector and small projects in the commercial sector. Equipped with an integrated switching device for back-up power. This allows the inverter to continue to supply the home with three-phase emergency power in the event of a grid failure. It is capable of operating in black-start mode.
The trend of increasing PV module yield is influencing overall PV system requirements. At the forefront of development, GoodWe’s ET inverters efficiently meet the needs of powerful solar rooftops to facilitate energy back-up, peak shaving and load management for optimised autonomy and reduced energy cost. The ET series can be combined with a range of battery capacities and brands, including the GoodWe Lynx Home F.
