Product Description

750VDC Three Phase Dump Load Ground Fault Monitoring On Grid Controller Wind Controller 0

Product Description:

Grid-Tied Controller for Wind Generator Systems

The Grid-Tied Controller is an extremely important component for wind generator systems that are connected to grids. This technology converts Three AC current from the wind turbine into DC current and feeds it into the grid-tie inverter.

GT-PCTC series is a professionally designed grid-tied controller for wind generators that integrates a Double safety control system: a PWM constant voltage system and a three-phase dump load brake system. This innovative solution allows the controller to interface with various solar inverters from brands like Growatt, Deye, Solis, and lvet, enabling these solar inverters to adapt to wind turbine operating conditions.

 

Applications:

In the field of wind power generation, the grid-connected controller plays a crucial role. This equipment enables smooth integration of wind energy into the power grid, allowing parallel operation of both wind energy and the power grid. Real-time monitoring and control of output voltage, current, and other relevant parameters of wind power systems is also possible with the grid-connected controller, ensuring the stable operation of the wind power generation system.

When it comes to the grid-connected controller in the wind power grid-connected inverter, it is equipped with a wide wind turbine voltage input range. The controller also has various safety features like automatic detection of DC output voltage and automatic unloading to ensure the safety of the output voltage. These features make sure that the integration of wind power into the power grid is successful and stable.

This canal flows day and night – I never thought it could make money. After Greef installed the system, it runs by itself. Every day I check my phone to see how much electricity was generated and how much I earned. I'll recover my investment in less than a year, and after that it's pure profit.

My farm is 30 kilometers from town, and connecting to the power grid would cost a fortune. Three years ago, I installed a solar panel system with a battery bank. It was sufficient during spring, summer, and fall, but in winter, we often had a week of consecutive overcast days—and the batteries would run out in just three days. Last year, I decided to add a variable-pitch wind turbine, connected it to the AC coupling port of the Deye inverter, and set up a hybrid solar-wind system. Throughout the entire winter, the battery level never dropped below 45%, and I never had to work in the dark again. The Deye app allows me to monitor both the solar and wind turbine data simultaneously, and the transition between them is so smooth it’s almost imperceptible. Relying solely on solar power during winter on a Nordic farm is a gamble. Only by combining a variable-pitch wind turbine with a Deye inverter—creating a wind-solar hybrid system—can you get through the winter with peace of mind.

“I built a small pico hydro system on the creek behind my off-grid cabin. The water head is only 3 meters and flow rate around 0.2 m³/s – too low for most generators. This axial flux coreless unit starts generating usable power at just 150 RPM. No cogging, no iron loss, and it’s silent. I’m getting 300-400W continuously, 24/7. My old induction generator would barely light an LED at that speed. Absolutely perfect for low-head hydro.”
