Key points for daily operation and maintenance of wind power systems

Once a small household wind power system is put into operation, daily care and maintenance are the key to ensuring its long-term stable power generation and extending its service life. You don’t need complicated tools, just develop the habit of regular observation and simple maintenance, and you can understand its health like an old friend. Maintenance work mainly focuses on the four aspects of "seeing, listening, checking, and remembering".

1. Daily observation and monitoring (seeing and listening)

This is the most direct and frequent maintenance.

Running status from a distance:

Check the rotation: Regularly observe whether the fan starts smoothly at different wind speeds, whether the rotation is smooth, and whether there is obvious jitter or swing. The blade rotation trajectory should be a stable circle.

Look at the appearance: When the weather is good, observe from a distance whether the leaves are intact and whether there are visible cracks, deformations or foreign matter attached.

Listen to the running sound:

Be familiar with the steady "whirling..." sound of the fan when it is operating normally. Be alert to any new abnormal noises, such as sharp grinding sounds, periodic banging sounds or irregular vibration noises. These may be early signs of bearing wear, loose components or blade damage.

View data and alarms:

Check the controller display or accompanying mobile APP regularly. Pay attention to: whether the real-time power generation changes reasonably with the wind speed; whether the battery voltage/power is charged and discharged normally; whether the cumulative power generation is consistent with expectations.

Pay attention to whether there are fault codes or alarm lights on the controller (such as excessive wind speed, undervoltage, etc.).

2. Regular inspection and maintenance (check)

When it is safe to do so (in calm or breezy weather and with electrical connections disconnected), proceed in cycles.

Structural inspection (quarterly or half-yearly):

Check whether the tower anchor bolts and main unit connecting bolts are loose or corroded.

Check the appearance of the cables, especially the corners of the tower body and pipe penetrations, for signs of wear, aging or animal gnawing.

Inspection and maintenance of core components (at least once a year):

Blade inspection: If conditions permit (for example, the tower pole can be tilted down), carefully inspect the leading edge, surface and root of each blade at close range to look for fine cracks, dents, lightning strike points or surface peeling. Minor injuries should be taken seriously.

Cleaning: Remove insects, dust and other attachments on the surface of the leaves. Clean bird's nests and debris on sensors (such as anemometers).

Lubrication: According to the requirements of the equipment manual, add the appropriate type of grease to the designated bearings (such as main shaft bearings and yaw bearings). This is key to ensuring long-term smooth operation.

Electrical connection inspection (annual):

In the power-off state, check whether all electrical connectors and terminals are tight and free of oxidation or ablation.

3. Battery system maintenance (for off-grid systems)

The battery is the "heart" of the system and requires special care.

Keep it clean and dry: Clean the battery surface and terminals regularly to prevent corrosion.

Check the liquid level (if it is an open lead-acid battery): Make sure the electrolyte level is within the specified range and use distilled water to replenish it.

Balanced charging: As recommended in the manual, perform a balancing charge on the battery pack regularly to maintain consistent performance of each cell.

4. Records and emergency response (recording)

Establish a maintenance log: simply record the date of each inspection, problems found, and actions taken (such as which bolts were tightened and what grease was added). This is a valuable device archive.

Clarify the response to exceptions:

Immediate shutdown: If you find that the blades are broken, the fan is swinging violently and abnormally, smoke or has a burnt smell, you should immediately remotely shut down or cut off the power supply, and contact a professional.

General abnormalities: For persistent abnormal noises, significant decrease in power generation, etc., after recording the phenomenon, consult or report for repair in a timely manner.

In summary, the daily maintenance of the wind power system can be summarized as: daily observation (watching the rotation, listening to the sound, reading data), regular physical examination (tightening the bolts, checking the blades, adding lubrication), paying more attention to the battery, and reporting abnormalities early. Through this combination, you can greatly improve the reliability and economy of the system, allowing clean wind power to serve your family longer and with greater peace of mind. Remember, the cost of preventive maintenance is much less than breakdown repairs and loss of power generation.
