Grid-Tied Controller is an essential component in wind generator on-grid systems. This state-of-the-art technology is responsible for converting Three AC current from a wind turbine into DC current and sending it to the grid-tie inverter. It plays a vital role in regulating the electrical output produced by wind turbines and ensuring that it is compatible with the power grid.
The GT-PCTC series wind professional grid-tied controller is a remarkable innovation in the field of wind energy. This controller has a double safety control system, which includes a PWM constant voltage system and a three-phase dump load brake system. This intelligent controller helps in managing the intermittency associated with wind energy and thereby ensures grid stability.
In addition, the GT-PCTC series controller also interfaces with solar inverters from brands like Growatt, Deye, Solis, and lvet. This feature enables solar inverters to adapt to wind turbine operating conditions, making it a versatile solution that can integrate with other renewable energy sources as well.
