Product Description
Model: GW20KN-DT
Smart DT Series 12-20KW | Three Phase | 2 MPPT
The GoodWe Smart DT series of inverters is specially designed for three-phase rooftop systems, the power range of 12kW, 15kW, 17KW and 20kW are ideal for small commercial usage. The integrated two MPPTs allow two-array inputs from different roof orientations. The SDT series inverter is small, light and easy to install. Suitable for both outdoor and indoor installations, this inverter offers a quiet operation due to its fan-less, natural convection cooling.
