Product Overview
The GoodWe GW80K-SMT is a three-phase on-grid string inverter designed for commercial and industrial rooftop PV systems. With an 80kW nominal output, 6 MPPTs and support for high-current PV strings, it is well suited to commercial sites that need reliable energy yield, flexible array design and robust outdoor performance.
Key Features
- 80kW three-phase grid-tied string inverter for commercial and industrial PV applications.
- 6 MPPTs help improve design flexibility across different roof sections, string layouts and orientations.
- Supports up to 21A DC input current per string for compatibility with modern high-power PV modules.
- Up to 150% DC input oversizing supports stronger solar harvesting and improved design flexibility.
- Type II surge protection on both DC and AC sides helps improve system protection and reliability.
- IP66-rated enclosure and smart fan cooling support dependable outdoor operation in demanding conditions.
Applications
- Commercial rooftop solar PV systems.
- Industrial grid-tied solar installations.
- Projects using high-power solar modules with higher string current requirements.
- Sites requiring multiple MPPTs for more flexible rooftop array design.
Why Choose This Product?
The GW80K-SMT is a practical option for commercial PV rooftops that need strong output capacity, flexible string design and reliable outdoor performance. Its 6-MPPT layout, high-current string support and compact high-power design make it a strong fit for C&I rooftop projects.
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 AFCI, PID recovery, reactive power compensation at night and power supply at night should be confirmed against the exact supplied variant before publishing.
- Final communication method, grid-code compliance and monitoring setup should be confirmed for the project before specification.
