When power generation is unsatisfactory, here are several areas to check first:


When you find that your home wind power generation system is producing significantly less electricity than in previous periods or than expected, don't immediately assume the equipment is damaged. Often, the problem lies in external factors that can be checked and resolved yourself. By prioritizing the following four areas, from outside to inside and from easy to difficult, you can often find the cause.


I. First, check for changes in "wind" and "environment"

This is the most common and easily overlooked reason.


Environmental obstruction: Carefully observe whether any new obstructions have appeared recently in the upwind direction of the wind turbine (the direction from which the wind comes)? For example, rapidly growing trees, newly built sheds, temporarily stacked materials, etc. These can disrupt airflow, placing the wind turbine in a "wind shadow," causing a sharp drop in efficiency.


Blade condition (from a distance): On a clear, windless day, carefully observe all the blades using binoculars or from a safe distance. Check for any obvious bending, cracks, or large amounts of bird droppings, dirt, spider webs, or other foreign objects attached to the surface. Anything that damages the blade shape or increases its weight will seriously affect wind capture efficiency.


II. Next, focus on mechanical and electrical connections

Check the physical condition of the equipment itself.


Listen and feel: When the wind turbine is running, listen carefully for any abnormal friction sounds, knocking sounds, or continuous sharp noises? Is the tower vibration noticeably abnormal? This may be a sign of worn or loose mechanical parts.


Check visible cables and connectors:


Along the line from the tower to the controller, check the cable sheath for damage or aging.


Check that all outdoor electrical connectors and plugs are secure, dry, and free of burn marks. Loose connectors can create high resistance, wasting energy.


III. Then, check the "brain" and "heart": the controller and battery

The controller and battery are the core of the system, and their condition directly affects the recording and storage of power generation.


Check controller data and alarms:


Wind speed comparison: Compare the real-time wind speed displayed by the controller with your actual perception. If the controller shows a very low wind speed but you feel the wind is strong, the anemometer may be stuck or damaged, leading to incorrect data. Check historical alarms: Check the controller for frequent "overspeed protection" or other alarm records, which may indicate that the wind turbine frequently shuts down due to strong winds.


Key assessment of battery health (critical for off-grid systems):


This is a common cause of "perceived low power generation." If the battery is old or damaged, its power storage capacity will be severely reduced. This manifests as: the battery indicator quickly shows "full" when there is good wind, but the power drops rapidly with even minimal use.


Self-check method: Observe whether the battery power drops unusually quickly during periods of no wind or at night.


IV. Conduct a systematic troubleshooting process

First, consider the weather: Confirm whether there has been an unusually calm period recently, ruling out natural seasonal or short-term climate fluctuations.


From outside to inside: Strictly follow the above order, starting with external factors such as the environment and blades, then moving to wiring and sensors, and finally analyzing controller and battery data.


Safety first: All inspections, especially those involving electrical components, must be performed in calm weather and with the power off. Do not attempt to disassemble anything if you are unfamiliar with the equipment.


In summary, when power generation is poor, a clear self-troubleshooting path is:

1. Check for new obstructions in the environment; 2. Check if the blades are dirty or damaged; 3. Listen for unusual noises or vibrations during operation; 4. Check if the cable connections are tight; 5. Verify the accuracy of wind speed data; 6. Check if the battery is aging.


Through these six steps, you have a high probability of finding the problem or providing accurate clues to professional maintenance personnel. Even if you cannot solve the problem yourself, an accurate description will greatly shorten the fault diagnosis time.
