Solar Inverter Fan Running Continuously | Is It Bad?

As you may know, with an inverter fan in the solar inverter, you can maintain an uninterruptible pace while the electricity drops down and reduce electricity consumption. Basically, the fans draw cool air into the inverter section and then exhaust it over the inverter components out of the vents.

Now here’s a thing. When users find that their inverter fans are running continuously, a number of them are concerned about whether the fans should act like that or if it’s a bad sign.

In this post, we’ll break down the entire concept of this activity. So, without any further ado, let’s get into them. 

Why Is Solar Inverter Fan Running Continuously?

The fact is solar inverter fans are designed to vary their speed based on the cooling needs of the room or the temperature settings you have chosen by utilizing advanced technology. They automatically adjust their speed according to the room’s temperature, ensuring that the room stays at a consistent temperature without drastic fluctuations. 

But when they’re running continuously, it means something else. There are a few reasons that cause this anomaly. Those are –

1. Inverter Is Overloaded

When you’re running high-watt appliances on the solar inverter, it faces an overload and has to work harder to keep up. As a result, the fans have to run continuously.

Ideally, inverters must not be loaded to their maximum rated output wattage for a long time. Rather it should always and only be loaded up to 80% of the maximum operational output.

2. Insufficient Ventilation

Another notable reason is the solar inverter isn’t getting enough ventilation. If the inverter fails to intake cool air and exhausts it, it won’t be able to cool itself down. Therefore, the fans need to run continuously.

3. Ambient Temperature Is High

If the ambient temperature is too high at the installation point, it can force the inverter fans to run without taking any breaks.

NOTE: In this case, it’s important to find the exact reason. If it’s due to overloading or insufficient ventilation, you can do the necessary things to reduce the load on the inverter or improve the ventilation. When the ambient temperature is high, make sure that nothing can impede the airflow in the air vent.

Is It Bad for Inverter Fan to Run Continuously?

In general, it isn’t so bad for a solar inverter fan to run continuously as most of the time the anomaly is temporary. It does so to maintain the overall performance while saving energy simultaneously. But if the fan is running excessively, it could be a sign of a problem. In every way, it’s best to consult with the manufacturer or a qualified technician to verify the condition of your solar inverter fan.

Frequently Asked Questions and Answers (FAQs)

What happens if the fan runs continuously?

When the fan runs continuously in a normal state, it ensures a more even distribution of heating and cooling, circulating the air if you have cold or hot spots in your place. If your fan starts and stops frequently, it doesn’t bring any benefit. Otherwise, running continuously can reduce stress and potentially help extend the fan’s lifespan.

How do I reduce the noise of my solar inverter fan?

If your solar inverter fan is making noise, you can reduce this issue by utilizing a combination of shielding, filtering, and noise cancellation or suppression. Sometimes metal enclosures for the inverter and the use of shielded, twisted pairs for wiring prove effective practices in this case.

Conclusion

To conclude, it can be said that your inverter fan is meant to run or pause according to the room temperature. Even when it runs, it typically tends not to do this continuously. Moreover, even though it runs continuously, it shouldn’t do this excessively. In short, continuous running of the inverter fan isn’t a bad sign (rather it indicates maximum usage), unless it becomes excessive.
