Product Overview
The GoodWe GW100K-GT is a three-phase on-grid string inverter designed for commercial and industrial solar PV systems. With a 100kW nominal output, 8 MPPTs and support for high-current PV strings, it is well suited to larger rooftop and commercial installations that need strong energy yield, flexible array design and dependable grid-tied performance.
Key Features
- 100kW three-phase grid-tied inverter designed for commercial and industrial PV applications.
- 8 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 the DC and AC sides helps improve system protection.
- IP66-rated enclosure supports outdoor installation in demanding site conditions.
- String-level monitoring and remote or on-site upgrade support help simplify system management.
Applications
- Commercial and industrial rooftop solar systems.
- Large grid-tied PV projects requiring multiple MPPTs and flexible string design.
- Installations using high-power solar modules with higher string current requirements.
- Sites where outdoor durability and centralised monitoring are important.
Why Choose This Product?
The GW100K-GT is a practical option for larger C&I solar projects that need strong output capacity, flexible PV design and robust protection features in one inverter. Its multi-MPPT layout, high DC string current support and outdoor-ready construction make it a solid fit for commercial grid-tied installations.
Important Notes
- This is an on-grid inverter intended 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 may depend on the exact model variant or market configuration and should be confirmed before publishing.
- Always confirm final grid-code, protection and communications requirements for the project before specification.
