What Status Indicators Should You Monitor for the Daily Operation of a Hybrid Wind-Solar Power System?

To ensure the healthy and efficient operation of your hybrid wind-solar power system, you don't need to be a technical expert, but you should develop the habit of regularly monitoring several key status indicators. These indicators are like the system's "pulse" and "thermometer," helping you detect abnormalities, assess performance, and manage the system effectively. The focus is on data related to power generation, energy storage, and the overall system status.

First, you should focus on the system's power generation performance, which is a direct reflection of energy input. Daily or every few days, you should check the controller display or the accompanying monitoring software (if available) and record the following core power generation data:

Total daily/monthly power generation: This directly reflects the system's output capacity.  Observe whether the trend of change is reasonable in conjunction with seasonal weather conditions.

Real-time power generation: Observe whether the total power reaches a high level during sunny and windy days; and whether the wind power generation part is working effectively during the night or on cloudy days. This allows for a direct assessment of whether both parts of the equipment are operating normally.

Independent power generation of solar and wind energy (if the system supports separate display): Understanding the contribution of each helps determine which part may be less efficient or malfunctioning under specific weather conditions.

Secondly, you must closely monitor the status of the energy storage unit—the battery—as this is crucial for the continuity of power supply. The battery is the system's "energy reservoir," and its status is vital.

Battery voltage or state of charge (SOC): This is the most critical indicator. Observe whether it cycles within the normal range: the voltage/charge should steadily increase during power generation in the daytime and decrease smoothly during power consumption at night. Avoid prolonged periods of "full charge" or "low charge."

Charging and discharging current: Understanding whether it is currently in a charging state (positive current) or a discharging state (negative current), and the magnitude of the current, can determine whether the energy flow is active and balanced.

Finally, you need to observe the overall health of the system and its environment. Besides data, visual inspection is equally important.

Status indicators/alarm information on the controller and inverter: Any abnormal indicator lights or alarm codes are clear fault signals from the system and should be addressed immediately according to the manual.

Physical condition of the equipment: Conduct regular visual inspections from a safe distance. Check if the wind turbine blades are rotating smoothly, without any unusual noises or vibrations; check if the solar panels are clean, free of obvious damage or obstructions; and check if the tower and support structure are stable.

Ambient temperature (if displayed by the controller):  Extremely high or low temperatures can affect the lifespan and performance of the battery and electronic components.

Develop a habit of keeping records: It is recommended to simply record the above key indicators (total power generation, battery level, and any abnormalities) and the weather conditions of the day in a notebook or spreadsheet. Over time, this log will become the system's most valuable "health record." By comparing historical data, you can easily identify abnormal decreases in power generation efficiency and trends in battery performance degradation, thus shifting from "reactive troubleshooting" to "proactive predictive maintenance," ensuring the long-term stable operation of the system.
