The CSI-25/30/36/40K-T480GL01-UB is a Canadian Solar family of four three-phase grid-tied string inverters that turn PV array DC power into AC power for local loads and the utility grid. The four models are rated at 25, 30, 36 and 40 kW, all on a 480 V grid connection. The 25K model has a maximum output current of 30.1 A and the 30K model has 36.1 A. The datasheet lists a maximum DC input voltage of 1000 V for the 36K model. Peak efficiency is listed at 98.6 percent. The CEC weighted efficiency is 98.3 percent for the 30K and 40K models. The 40K model is specified for a 60 Hz grid and operates between 59.5 and 60.5 Hz. Every model has integrated DC arc-fault circuit protection (AFCI).
