Detecting a Faulty Solar Inverter: 10 Key Indicators

Are you experiencing a drop in solar energy production? Worried that your solar power system might not be performing optimally?

Understanding the health of your solar inverter is crucial for maximising your solar energy output. In this article, we'll explore the key indicators that help with detecting a faulty solar inverter and provide insights on what to do next.


How do I know if my solar inverter is bad?

1. Decreased Energy Production: 

One of the most noticeable signs of detecting a faulty solar inverter is a decrease in energy production. If you've observed a significant drop in the amount of energy your system is generating, it could indicate an issue with the inverter.

2. Error Messages:   

Modern solar inverters are equipped with diagnostic features that display error messages in case of malfunctions. Keep an eye out for any error codes (see below) or warning lights on your inverter's display panel.

3. Fluctuating Output:   

Are you noticing inconsistent energy output? Fluctuations in energy production, especially without any changes in weather conditions, could point to an underlying problem with your inverter.

4. Inverter Not Turning On:

If your solar inverter fails to turn on or consistently shuts down unexpectedly, it's a clear indication of a problem that needs attention. Contact us today, and we'll help you out!

5. Physical Damage:  

Inspect your solar inverter for any signs of physical damage such as cracks, corrosion, or water ingress. Physical damage can compromise the functionality of the inverter and should be addressed immediately.

6. Strange Noises:   

Unusual sounds like buzzing or clicking emanating from your solar inverter may signal internal component failures, requiring prompt investigation. Fortunately, with over 30 years of expertise in component-level repair, ENS stands out as your trusted solution. It's our mastery in this very field that sets us apart.

7. Overheating:

Touch your solar inverter's shell occasionally to check for overheating. Excessive heat buildup can lead to performance issues and even permanent damage to the inverter.

8. Age of the Inverter:  

Like any electronic device, solar inverters have a lifespan. If your inverter is approaching the end of its expected lifespan, it may be prone to failures and should be monitored closely.

9. Inconsistent Monitoring Data:  

Review the monitoring data of your solar power system for any irregularities or inconsistencies. Anomalies in data patterns could signify underlying issues with the inverter.

10. Frequent Tripping:

Is your circuit breaker frequently tripping? While it could be due to various factors, a malfunctioning solar inverter is one potential cause that shouldn't be overlooked.

If you've noticed any of these signs, it's essential to act promptly to diagnose and rectify the issue. Contact European Network Services for professional solar inverter diagnostics, repair, and sales of new and refurbished inverters.
