Product Overview
The GoodWe GW125K-GT is a three-phase on-grid string inverter designed for commercial and industrial solar PV systems. With a 125kW nominal output, 10 MPPTs and support for high-current PV strings, it is well suited to larger rooftop and C&I installations that need flexible array design, strong energy yield and dependable grid-tied performance.
Key Features
- 125kW three-phase grid-tied string inverter for commercial and industrial PV applications.
- 10 MPPTs help improve design flexibility across multiple roof sections, string layouts and orientations.
- Supports up to 21A DC input current per string for compatibility with modern high-power PV modules.
- Type II surge protection on both AC and DC sides helps improve system protection and reliability.
- IP66-rated enclosure supports outdoor installation in demanding site conditions.
- Supports up to 150% DC input oversizing and 110% AC output overloading for improved design flexibility.
Applications
- Commercial and industrial rooftop solar systems.
- Large grid-tied PV projects requiring multiple MPPTs and flexible string configuration.
- Installations using high-power solar modules with higher string current requirements.
- Sites where outdoor durability, monitoring and serviceability are important.
Why Choose This Product?
The GW125K-GT is a practical option for larger C&I solar projects that need higher output capacity, broad PV design flexibility and robust protection features in one inverter. Its 10-MPPT layout, high-current string support and outdoor-ready construction make it a strong fit for demanding commercial grid-tied installations.
Important Notes
- This is an on-grid inverter for commercial and industrial PV applications.
- Installation and commissioning should be completed by a qualified electrician or solar installer.
- Optional functions such as PID recovery, C5 protection and AFCI should be confirmed against the exact supplied variant before publishing.
- Final grid-code, communications and project-specific compliance requirements should be confirmed before specification.
