About This Product

GW120K-HT is a GoodWe HT Series three-phase string inverter for commercial, industrial and small utility solar systems. It is designed for high-capacity grid-connected PV arrays where multiple strings and flexible roof or ground-mount layouts are required. The HT Series sits in GoodWe’s larger commercial inverter range and is aimed at projects that need higher DC input capability, multiple MPPTs and centralised monitoring without moving to a central inverter design.

Who This Product Suits

GW120K-HT suits GoodWe commercial solar installations such as warehouses, factories, large sheds, schools, farms, shopping centres and small utility-scale arrays. It is best suited to projects with a three-phase supply and enough panel capacity to justify a 120 kW class inverter. It is also useful where the array has multiple roof faces or string groups, because the high MPPT count gives installers more flexibility when designing around different orientations or string lengths.

Specifications Explained

GW120K-HT is a 120 kW three-phase grid-tie inverter with up to 12 MPPTs and two string inputs per MPPT. The inverter supports a maximum DC input voltage of 1,100 V and a broad MPPT operating range of 180-1,000 V, giving installers flexibility across large commercial PV arrays. It has integrated PV string current monitoring, insulation resistance detection and residual current monitoring, with Type II surge protection on the DC and AC sides depending on the supplied regional configuration. The unit is designed for outdoor commercial use with IP66 protection and can be monitored through GoodWe’s SEMS platform, with commissioning commonly handled through the SolarGo app.

Summary

GW120K-HT is a GoodWe commercial string inverter for large three-phase solar projects that need strong DC input flexibility and detailed string-level design options. Its 12 MPPT layout makes it practical for complex commercial roofs and larger ground-mount systems. For installers, the main appeal is a high-capacity GoodWe inverter platform with monitoring, protection features and a layout suited to serious C&I solar work.
