When the wind power or photovoltaic side does not generate electricity, the operating logic and precautions of the system

In the wind-solar hybrid system, wind power generation and solar power generation do not maintain synchronized output at all times, and it is often the case that one side does not generate power temporarily. Understanding the operating logic of the system at this time and responding to it is an important part of ensuring stable household power consumption.

1. How the system automatically responds to "unilateral shutdown"

When one side of the photovoltaic or wind power plant stops generating electricity due to weather, the system will not be paralyzed. The controller will monitor the power generation status of both sides in real time and automatically shift the work focus to the other side that is still generating power. For example, on a sunny day with no wind, the wind turbine may be stationary, but the solar panels will take on all the power generation tasks; at night or on a windy and rainy day, the solar panels will not work, and the wind turbine will become the main source of electricity.

At the same time, the system will give priority to using the electric energy stored in the battery to make up for the gap. The intelligent controller will automatically adjust the discharge intensity of the battery based on the remaining power generation and the current household electricity demand to maintain power supply balance. If single-side power generation and battery discharge still cannot meet the demand, the system will start the backup power supply (such as connecting to the power grid or starting a fuel generator) according to the preset plan to achieve seamless switching and ensure that important power is not interrupted.

2. Practical points that users need to pay attention to

Observe and confirm status

When it is found that one side of the equipment is not running for a long time (such as the fan does not move on a windy day, and the photovoltaic panel has no output on a sunny day), you should first check the specific data through the controller to confirm whether it is a normal shutdown (such as the wind speed is too low, there is no light at night), rather than an equipment failure. The controller usually displays the real-time status and alarm information of each power generation unit.

Adjust electricity usage habits

On days when only a single energy source generates electricity, peak shifts or reductions in electricity demand should be made consciously. For example, on cloudy days when only photovoltaic power is relied on, reduce the use of multiple high-power appliances at the same time; during periods when only wind power is relied on, concentrate high-power-consuming activities at times when the wind is strong. This helps reduce stress on the system and prevents the battery from draining too quickly.

Pay attention to battery status

When one side generates electricity, the battery will cycle more frequently, so special attention needs to be paid to its power and voltage changes. To avoid battery damage due to over-discharge, if the controller shows that the power continues to drop to a low level, you should proactively reduce unnecessary power consumption or activate backup power in a timely manner.

Do daily maintenance

Regularly check the status of the equipment on the side that is not working. For example, in seasons where there is no wind for a long time and photovoltaic power generation is dominant, it is also necessary to check whether the fan blades are normal and clean debris; in winter or when there is continuous rain and wind power is dominant, attention should also be paid to keeping the surface of the photovoltaic panels clean so that efficient power generation can be resumed immediately when the weather improves.

3. Response to long-term unilateral non-power generation

If the equipment on one side has no power generation for many consecutive days and the weather is excluded, there may be a fault. Common problems include loose wiring, blown fuses, or damage to the equipment itself. At this time, it is not recommended that non-professionals dismantle and repair it by themselves. Professional maintenance personnel should be contacted for inspection and treatment.

The advantage of the wind-solar hybrid system lies in "complementarity", and the suspension of power generation on one side is a natural phenomenon in its normal operation. Users only need to understand the logic of its automatic adjustment, and cooperate with reasonable power consumption arrangements and basic maintenance, then they can rely on the system to cope with changing weather and enjoy continuous and stable green power.
