Description
Description
The GoodWe ET G2 series is a three-phase hybrid inverter family designed for solar systems between 6–15 kW. It can be used with high-voltage lithium-ion batteries and provides management of PV production, battery energy storage, grid operation, and backup output in one device.
The battery voltage range is 150–720 V. The maximum charging and discharging current is 30 or 40 A, depending on the model. On the solar side, lower power models have 2, while larger versions have 3 MPP trackers. The MPPT operating range is 120–850 V.
The maximum PV input power ranges from 9.6–24 kW, depending on the model. The multi-MPPT design allows for system configurations that can be used even with solar systems of different orientations or consisting of multiple arrays.
The backup output is used to supply a separate consumer circuit. The nominal backup power is 6–15 kVA. With adequate PV and battery-side power, short-term overload capacity can be up to 12–18 kVA for 60 seconds, depending on the model.
The enclosure has IP66 protection and is designed for wall mounting. Cooling is achieved by natural convection. The series features DC and AC Type II surge protection. Communication is available via RS485 / CAN, Wi-Fi, LAN, and Bluetooth connections.
