Solar Inverters

If this occurs check what time of day, it is or take note of the weather conditions. It may be the sun is going down and it may just be that your system is shutting down for the day. We advise that you check it again in the morning when the sun is up to see if it is still showing the same fault light.

The same can be said if the weather is inclement.

If it is not either of these things it may indicate there is a potential fault with your system, please contact us at Solar Integrity immediately.

Give me all the details

Seeing a red, orange, or fault light on your solar inverter is not a cause for panic, but it does require attention. By understanding the potential causes behind these warning lights and taking appropriate steps, you can ensure the optimal performance and longevity of your solar power system.

Regular maintenance, timely professional intervention, and a proactive approach to addressing issues will help you make the most of your investment in renewable energy. If in doubt, always consult with a qualified solar professional to diagnose and resolve any concerns promptly.

When a red, orange, or fault light appears on your solar inverter, it can be a cause for concern. However, these indicators are designed to communicate issues rather than instigate panic. 

What does a red light mean?

If you observe a red light on your inverter, it indicates a critical issue that requires immediate attention. This could range from a malfunction in the inverter itself to a severe fault in the solar panel system. To resolve this, call us or if out of hours and you really want to know refer to your inverter’s user manual, as it frequently contains a troubleshooting guide specific to your model. Access to your user manual is in your post installation documentation, it may be a QR code in the manual. Or if your inverter is older you may need to google the model number.

What does an orange light mean?

An orange light generally denotes a less severe issue compared to red, suggesting a potential problem that necessitates investigation but may not be an emergency. Common reasons for an orange light include minor faults, communication issues between components, or an upcoming need for maintenance. Once again, calling us or consulting your inverter’s manual is a good initial step in comprehending the specific concern.

What is a fault light?

A fault light, whether red or orange, indicates a specific problem within the inverter or the solar system. Faults may involve issues with the inverter’s internal components, problems with the DC or AC connections, or even issues related to the solar panels themselves. When the fault light is activated, it is vital to promptly contact a professional solar installer to evaluate and address the underlying problem.

Causes and solutions

Overheating, often due to inadequate ventilation or excessive ambient temperatures, can trigger a red or orange light. The solution may involve improving the inverter’s cooling system, ensuring proper airflow, clearing the airways of leaves or debris so the cooling fan can operate properly or relocating the inverter to a cooler space.

Fluctuations in voltage, whether too high or too low, can cause warning lights. This may be due to issues with the electrical grid or the solar panel system. In such cases, a certified electrician or solar technician should be consulted to assess and rectify the voltage irregularities.

Orange lights often indicate communication errors between system components. This may involve the inverter’s inability to connect with monitoring devices or issues with data transmission.

Checking the connections and contacting your solar system provider for assistance can help resolve communication-related problems.

In some instances, internal components of the inverter may be faulty, leading to warning lights. Repair or replacement of these components may be necessary, requiring the expertise of a qualified solar technician.

What is a green light

The green light means everything is working as designed.

What to do when lights appear?

Your inverter’s user manual or the internet are valuable resources. It often contains troubleshooting steps and explanations specific to your model.

If you cannot resolve the issue based on the manual or if the problem persists, it is crucial to contact us. We have the expertise to diagnose and address complex issues within the solar system.

Consider scheduling regular maintenance checks for your solar system to prevent potential issues. Professional inspections can identify and address issues before they escalate, ensuring the continued efficiency of your solar setup.
