GoodWe GT Series 100-125kW Three Phase String Inverters
Model Series: GT Series
Manufacturer: GoodWe
Product Overview
The GoodWe GT Series string inverter is engineered for commercial and industrial (C&I) applications, aiming to enhance productivity and achieve high power density. This series features up to 10 MPPTs and a high input current of 21A per DC string, which collectively increase the overall yield when used with high-power PV modules. The design includes a new DC & AC cover and a flexible AC entry box that accommodates 95mm² AC cable, facilitating faster and easier installations. An optional PID (Potential Induced Degradation) recovery function is available to improve module performance. Safety is a paramount concern, with both DC and AC sides equipped with Type II surge protection to safeguard the inverter against lightning, thereby enhancing the safety and reliability of the PV system. The GT Series boasts a noise level of 70dB, IP66 rating, 150% DC input oversizing capability, and can be paralleled with up to 60 units. These features combine to offer a comprehensive solution for increasing return on investment (ROI) in C&I PV projects.
A white GoodWe GT Series inverter unit is shown, featuring a sleek, modern design with ventilation grilles. It is positioned against a blurred background of a modern building facade with illuminated windows, suggesting an industrial or commercial setting.
