About the product

The ET 40–50 kW series from the EMEA catalogue targets commercial and industrial systems with a battery. GW50K-ET-10 combines 50 kW rated power with a 75 kW maximum PV input.

The battery input operates between 200 and 800 V at up to 100 A, i.e. up to 55 kW of charge and discharge power. Backup supply (50 kVA rated, 60 kVA for 60 s) requires the GoodWe STS box; the datasheet does not state a switch-over time in milliseconds.

Communication via RS485, WiFi + LAN + Bluetooth or a 4G module; BMS via CAN. The 25 and 30 kW models of the same series are not intended for the European market according to the datasheet note.
