The Goodwe GW25K-ETA-G20 sits one step above the 20 kW unit in the ETA G20 hybrid lineup, delivering 25 kW of three-phase AC output while sharing the same chassis, four-MPPT input stage, and 200% DC oversizing window. It targets larger homes and small commercial sites looking to combine a sizeable rooftop array with high-voltage battery storage scalable to 108 kWh. The integrated 80 A whole-home backup port, sub-4 ms transfer, and AFCI 3.0 arc-fault protection bring the same resilience and safety profile as the smaller models, with IP66 outdoor mounting and a -35 to +60 degrees Celsius operating range.
