The GoodWe GT Series string inverter is an ideal choice for commercial and industrial (C&I) applications, designed to enhance productivity and realize high power density. With multiple MPPTs and a high input current of 21A per DC string, these inverters increase the overall yield, especially when paired with high-power PV modules. The optional PID (Potential Induced Degradation) recovery function is also supported for improved module performance. Safety is paramount, with both the DC and AC sides equipped with Type II surge protection to safeguard the inverter from lightning strikes, ensuring upgraded safety and reliability for the PV system. The GT Series inverters are engineered with an unrivaled set of features to deliver increased return on investment (ROI) for C&I PV projects.
