GoodWe GT Series Inverters
High-Performance Solar Solutions for Commercial and Industrial Applications
Overview
The GT series inverters from GoodWe are the ideal choice for commercial and industrial (C&I) applications, designed to enhance productivity with superior energy yields and high power density. Featuring multiple MPPTs and a high input current of 21 A per DC string, these inverters optimize performance with high-power photovoltaic modules. An optional PID (Potential Induced Degradation) recovery function further boosts module performance.
Safety is paramount. Both DC and AC sides are equipped with Type II surge protection to safeguard the inverter against lightning strikes. Integrated AFCI (Arc Fault Circuit Interrupter) technology provides enhanced safety and reliability for the photovoltaic system. With an unparalleled set of features, the GT series inverters are engineered to deliver a higher return on investment (ROI) for C&I projects.
