Daily operation status monitoring and basic data interpretation of wind and solar hybrid systems

After installing a home wind-solar hybrid system, through daily monitoring and understanding a few key data, you can easily grasp its "health status" and power generation performance to ensure stable and efficient operation of the system.

1. What should we look for in daily monitoring?

Daily monitoring does not require complicated operations. The main thing is to develop observation habits:

Look at the controller display panel: This is the "dashboard" of the system. Take a look at it every day to understand whether solar power is the main power generation, wind power is the main power generation, or both are working at the same time.

Listen to the sound of the fan running: there should be a steady whistling sound when the fan is running. If there is abnormal metal friction, impact sound or severe vibration, the fan should be shut down remotely and inspected immediately.

Check the appearance of the equipment: Regularly (such as weekly) visually inspect the surface of the solar panel to see if there is any obvious dust, bird droppings or obstructions. Check whether the fan blades are intact and whether there are any foreign objects wrapped around them.

Observe battery status: Most system controllers display the battery percentage. Pay attention to the changing trend of the battery capacity after charging and discharging every day to avoid the battery being too low (such as less than 20%) or overfull for a long time.

2. Interpretation of key data: understanding the “dashboard”

The system controller or supporting mobile APP usually displays the following types of core data, and it is important to understand their meaning:

Instantaneous power (unit: kilowatt kW)

What it is: How fast or slow the combined power generated by solar panels and wind turbines is at this moment.

How to see it: During the day when it is sunny, this number should be higher; at night or when it is windy, it may show the power of the wind power. If it is 0 for a long time or much lower than expected, it means that the power generation part may be faulty.

Daily power generation (unit: kWh)

What it is: How much electricity has the system produced in the past 24 hours. This is the core data for measuring system effectiveness.

How to see it: Record and compare the daily power generation in different weather conditions (sunny days, cloudy days, windy days) to intuitively understand the complementary effects of the system. For example, solar power generation decreases on cloudy and rainy days, but if wind power generation increases significantly, this reflects complementary advantages.

Battery voltage/capacity (unit: volts V or percentage %)

What it is: Reflects the "remaining fuel level" of the battery.

How to see it: The voltage or percentage slowly drops when electricity is used and rises back up when power is generated. You should avoid the battery being in the red low battery range (such as less than 25%) for a long time, which will affect the battery life. When charging, you should also avoid staying at 100% full charge for a long time (some systems will intelligently manage this).

Load consumption (unit: kWh)

What it is: How much electricity the household actually used from the system in the past 24 hours.

How to see it: Compare "daily power generation" and "load consumption". If the power generation continues to be greater than the consumption, it means that the system has surplus power, the battery is always full, and the operation is ideal. If consumption exceeds power generation for a long period of time, it means that the system scale may be insufficient, or household electricity consumption habits need to be adjusted.

3. Simple judgment of abnormal situations

You need to be more vigilant when you find the following situations:

A long-term anomaly in the data: several days in a row of very low power generation on sunny and windy days.

Abnormal battery power: The battery power cannot be charged during the daytime power generation period, or the battery power is discharged abnormally fast.

Abnormal equipment status: the fan stalls for no reason, the solar panel displays zero power, and the controller alarms.

Summary suggestions: The core of daily monitoring is to observe trends and detect abnormalities. You don’t have to obsess about the fluctuations in numbers every moment, but you need to establish a basic understanding of the range of data under normal circumstances (such as how much electricity is usually generated on a sunny day). Developing the habit of spending a minute or two every day to check key data, or reviewing the data report of the mobile APP once a week, can make you a "qualified steward" of your own home energy system, ensuring its long-term reliable operation while enjoying clean power.
