Introduction
A compact controller helps rooftop turbines run smoother, safer, and far more efficiently.
Reliable Control for Urban Wind Systems
Rooftop wind turbines face fast-changing conditions. Gusts, turbulence, and vibration influence performance every minute. To stay efficient, these turbines need smart control of generator load, yaw orientation, and structural health. The GOcontroll Moduline Mini I gives installers and researchers a rugged, modular platform that handles each of these tasks with confidence. As a result, small urban turbines become cleaner, quieter, and far easier to manage.
A Modular Platform for Rooftop Wind
The Moduline Mini I includes four module slots, two CAN 2.0B interfaces, Ethernet, USB, and a powerful i.MX 8M Mini processor. Its CNC-milled aluminium housing protects the electronics from outdoor and rooftop conditions.
Because the controller accepts not only digital I/O, but also analog inputs, and 4–20 mA inputs, it adapts easily to different wind turbine configurations. It reads rotor speed, generator voltage, yaw position, and vibration sensors. It can also drive actuators, load resistors, and orientation motors.
Smooth Generator-Load Control
Rooftop turbines often run in unstable airflow. Therefore, managing generator load is essential for safe and efficient power production.
The Moduline Mini I reads real-time electrical values and adjusts the load banks or MPPT interface quickly. This prevents runaway RPM, protects the generator, and improves energy capture. Furthermore, controlled load steps keep the turbine stable during gusty conditions, which reduces wear and extends equipment life.
Active Orientation and Yaw Control
Wind direction shifts constantly above buildings. If a small turbine cannot rotate smoothly into the wind, it loses performance and increases stress.
The controller monitors wind direction through sensors or external data. It then drives yaw motors or actuators to align the turbine. Because the logic runs locally on the controller, orientation reacts quickly. This results in better production, lower noise, and less vibration across the tower and mounting structure.
Vibration Monitoring for Structural Health
Rooftop installations must stay safe. Excess vibration can damage mounts, bearings, or nearby structures.
The Moduline Mini I monitors vibration through accelerometers and 4–20 mA sensors. It also compares vibration levels with rotor speed to detect imbalance or worn bearings early. When vibration rises, the controller can reduce load, slow the turbine, or trigger alerts. Therefore, maintenance becomes proactive instead of reactive.
Clear Dashboards Through Node-RED
Node-RED is preinstalled on the controller. It gives users simple dashboards for:
-
Rotor speed and wind direction
-
Generator voltage and load state
-
Vibration trends
-
Orientation position
-
Energy output
-
Warning states
Additionally, Node-RED supports MQTT, HTTP, and other protocols. This makes remote monitoring easy for installers, research teams, and building managers.
A Scalable Control Node for Small Wind
Urban turbines come in many shapes and sizes. Fortunately, the Moduline Mini I grows with them. Teams can add new sensors, revise control logic, or integrate the turbine into a larger microgrid. Its rugged housing and flexible software stack ensure long-term reliability on rooftops.
As a result, installers, researchers, and small OEMs gain a clean, modular, and intelligent controller that keeps rooftop wind systems running at their best.
