Product Description:

The use of wind turbine controllers finds its major application in wind power systems. These controllers, being intelligent devices, play a crucial role in optimizing energy utilization and ensuring the safe and stable operation of the system.

Wind turbine controllers find several specific applications in the system, some of which are:

Active power control to maintain the wind turbine output within the desired limits
Reactive power control to maintain the voltage at the desired level
Yaw control to keep the wind turbine aligned with the wind direction for higher energy capture efficiency
Pitch control to regulate the blade angles to match the wind speed and maintain a constant rotational speed
Over-speed protection to prevent any damage due to excessive wind speed
Emergency shut-down in case of system faults or failures

The efficient functioning of wind power systems is largely dependent on the effective use of wind turbine controllers.

Applications:

A solar and wind controller is an essential component in any off-grid power system. The GBBC wind controller, manufactured by the renowned Controller Brand for Greef, is a reliable and efficient solution for managing wind power systems. The product is made in Qingdao and comes with a CE certification, ensuring its quality and safety. The controller is adjustable with wind dump load rotate speed (Rota) and wind charging range that can be set between DC(20-150)V/DC(120-400)V. The under-voltage (Low) can also be adjusted to 40.8V/210V depending on the requirements of the system.

The GBBC wind controller has a rated wind power of 1KW/2kw/3kw/5kw/10KW and a nominal system voltage of 48V/240V. It can be used in various settings, including remote homes, cabins, telecom stations, and remote monitoring systems. The controller is also suitable for wind turbines in low wind speed areas.

The GBBC wind controller ensures that the wind turbine is charging the battery within the required range, preventing overcharging and undercharging, which could damage the battery. The controller also has a wind dump load function that protects the battery from overcharging when the wind speed exceeds the rated speed.

The GBBC wind controller is easy to install and use. It comes with foam and plywood case packaging, ensuring its safety during transportation. The minimum order quantity is 1 set, and the price is negotiable. The delivery time is 25 working days, and payment terms include T/T, Western Union, MoneyGram, and L/C. The supply ability is ample, ensuring that the product is always available to customers.

In conclusion, the GBBC wind controller is a reliable and efficient solution for managing wind power systems in off-grid settings. Its adjustable settings, reliability, and ease of use make it an ideal choice for a wide range of customers. If you are looking for a quality wind controller, the GBBC wind controller is an excellent choice.

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 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.
