The GoodWe GT 125kW inverter is a high-performance three-phase string inverter, purpose-built for commercial and industrial (C&I) solar PV applications. With up to 10 MPPTs, a maximum efficiency of 99%, and support for 21A per string input current, it is optimized to work seamlessly with today’s high-power PV modules.
Engineered for maximum energy yield and reliability, the inverter allows 150% DC input oversizing and 110% AC output overloading, ensuring superior flexibility in system design. Its IP66-rated enclosure with optional C5 protection makes it suitable for harsh outdoor conditions.
Safety is a top priority: the GT 125kW features Type II surge protection (AC & DC sides), integrated DC switch, residual current monitoring, and optional AFCI & rapid shutdown functions. With smart monitoring, remote upgrade capabilities, and user-friendly maintenance (lightweight design, fan replacement), this inverter offers the ideal balance of performance, safety, and reliability for large-scale PV projects.
