Product description
GoodWe GW20K-ET – 20 kW Hybrid Inverter, 3-phase
The GoodWe GW20K-ET from the ET 15–30 kW series is an advanced solution for large photovoltaic installations, including commercial and industrial PV systems with energy storage. The unit provides AC power of 20 kW, supports HV batteries 200–800 V and a maximum charge and discharge power of 20,000 W. With 2 MPPT trackers (30 A, 200–850 V range) it ensures flexible system design and high conversion efficiency. The backup section delivers 20 kVA (up to 24 kVA for 60 s), enabling supply of critical loads during grid failures. The inverter features numerous protections — DC SPD Type II, AC SPD Type III, anti-islanding, current monitoring — and optional AFCI and Rapid Shutdown. With a protection rating of IP66, active cooling (smart fan) and quiet operation (<45 dB), it is reliable in demanding conditions. The standard warranty is 5 years with an option to extend to 10 years.
