Wind Turbine 3 Phase Dump Load Voltage 750±5Vdc On Grid Controller Short Circuit / Islanding Protection 9

Product Description:

The most important component in wind generator on-grid systems is the Grid-Tied Controller . This technology converts Three AC current from wind turbine into DC current and sends it to the arid-tie inverter.

The GT-PCTC series is a professional grid-tied controller specifically designed for wind energy. It features two safety control systems: PWM constant voltage system and three-phase dump load brake system.

This innovative solution is compatible with solar inverters from trusted brands like Growatt, Deye, Solis, and lvet. With this feature, solar inverters can adapt to wind turbine operating conditions, which adds to the efficiency of the energy systems.

 

Applications:

Wind generator controller

A wind generator controller is an electronic device that controls the output of a wind turbine. Its primary function is to optimize the energy generated by the wind turbine, prevent damage to the wind turbine, and ensure that it operates safely and efficiently.

The controller is responsible for regulating the speed of the turbine rotor and the pitch of the turbine blades. It achieves this by measuring the wind speed and direction and adjusting the power output accordingly. The controller can also disconnect the turbine from the power grid if there is a fault or if the turbine is not generating enough power.

There are many different types of wind generator controllers available, each with their own features and capabilities. Some controllers are designed for use with small wind turbines, while others are suitable for larger industrial turbines. The choice of controller will depend on the size of the wind turbine, its power output, and the specific requirements of the application.

Overall, the wind generator controller plays a crucial role in the effective operation of a wind turbine and is essential for maximizing the energy output and ensuring the safety of the turbine and surrounding equipment.

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.

I run a small dairy farm in northern Norway, far from the power grid. A few years ago, I installed solar panels and a Deye inverter, but the solar system basically stops working in winter, and the diesel generator was costing me a fortune. This year, I added this variable-pitch wind turbine and connected it to the Deye inverter for a hybrid solar-wind system, and we haven’t had a single power outage all winter. This wind turbine starts up at low wind speeds of just 2–3 on the Beaufort scale. During blizzards, the blades automatically pitch down to slow the turbine, preventing runaway speeds, and it’s much quieter than my neighbor’s fixed-pitch model. The Deye inverter’s switching logic is smart—it prioritizes solar power when available, and automatically switches to the wind turbine when solar output drops. It’s all clearly visible on the app. Now, the diesel generator is practically idle. Wind and solar backing each other up—that’s true off-grid freedom.

“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.”
