Key Points for Daily Operation Monitoring and Management of Wind-Solar Hybrid Systems

After the installation of a wind-solar hybrid system, establishing a habit of daily monitoring and management is crucial. Simple and continuous observation and maintenance can ensure efficient and stable system operation, extend equipment lifespan, and promptly identify potential problems.

I. Core Contents of Daily Operation Monitoring Daily monitoring primarily involves observation, listening, and inspection, requiring no complex operations.

Checking Controller and Display Data: The controller is the system's "dashboard," and daily checks should be a habit. Key Focus Areas:

Power Generation: Observe whether solar or wind power is currently generating electricity, or both simultaneously.

Battery Charge/Voltage: Monitor the battery's "remaining charge," ensuring it remains within a reasonable range (generally avoiding prolonged periods below 20% or above 95%).

Load Status: Understand the current power consumption of electrical appliances.

Alarm Messages: If fault codes appear, address them promptly.

Observing Equipment Appearance and Status:

Solar Panels: Regularly (e.g., weekly) visually inspect the surface for obvious dust, bird droppings, fallen leaves, or snow accumulation, as these can severely impact power generation efficiency.

Wind Turbine: When wind conditions are suitable, observe whether it rotates smoothly and listen for any abnormal friction, impact, or violent vibration sounds.

Lines and Connectors: Inspect main cables and connectors for looseness, aging, or signs of animal chewing.

II. Regular Maintenance and Management Perform periodic maintenance according to the season and usage.

Regular Cleaning: Clean the solar panels every 1-3 months, depending on the local environment. Choose a time when the panel surface temperature is not high, such as early morning, evening, or cloudy days, and wash with a soft cloth or clean water to remove dirt that affects power generation efficiency.

Check Fasteners: Before and after the windy season, focus on checking and tightening the solar panel brackets, wind turbine towers, and all connecting bolts to prevent loosening due to vibration.

Daily Management of Batteries:

Keep the battery installation site well-ventilated, dry, and clean.

For lead-acid batteries, regularly check the terminals for corrosion and apply a special protective grease after cleaning.

Avoid prolonged deep discharge of the battery and avoid prolonged full-charge float charging.

III. Data Recording and Performance Analysis Proper record-keeping helps in understanding the system's health and promptly identifying problems.

Establish an operation log: Simply record the total daily or weekly power generation, major weather conditions, and any abnormal situations.

Conduct seasonal comparisons: Compare power generation data across different seasons (e.g., summer vs. winter). A sustained and unreasonable decrease in power generation under the same weather conditions may signal equipment performance degradation or a malfunction.

Monitor electricity consumption matching: Analyze the relationship between power generation and household electricity consumption. If power generation consistently exceeds consumption, and the battery is always full, the system configuration may have a surplus; conversely, it may require adjusting electricity consumption habits or considering capacity expansion.

IV. Abnormal Situation Handling and Safety Bottom Line

Adhere to the principle of safety first: Before performing any inspection or maintenance, always safely shut down the system according to operating procedures, especially disconnecting the battery. Live work is strictly prohibited.

Preliminary Judgment of Common Abnormalities:

Sudden Drop in Power Generation: First, rule out consecutive cloudy and windless days. If weather is not the cause, check in sequence whether the solar panels are obstructed, and whether the wind turbine is stopped or making abnormal noises.

Continuous controller alarms: Based on the codes in the instruction manual, common causes include battery overcharge/over-discharge, load short circuit, and abnormal input from the wind turbine or photovoltaic system.

Seek professional help promptly: When encountering electrical faults, structural problems (such as abnormal noise from the wind turbine main shaft or tower swaying), or complex controller alarms that cannot be resolved, contact a professional service provider immediately. Do not attempt to disassemble critical equipment yourself.

Summary: Frequent observation, data-driven approach, and early maintenance. Effective daily management hinges on integrating "observation, recording, and simple maintenance" into your daily routine. It doesn't require you to be an expert, but it does require meticulousness and persistence. By checking the data daily and performing regular cleaning and inspections, you can become a qualified "steward" of your home energy system, maximizing its efficiency and reliability, and ensuring this green investment serves you for a long time.
