Nifty Maintenance Tips For Solar Inverters To Last Longer

Nifty Maintenance Tips For Your Solar Inverter

A solar inverter is a vital component in your solar power system. A solar inverter converts your solar panels’ direct current (DC) energy into alternating current (AC) electricity. It can power your household appliances, lighting, and electronic devices.  

When your inverter has issues, it hampers the connection of solar panels in your home. And it potentially leads to unexpectedly high utility bills.  

So, how can you ensure the smooth operation of your solar inverter?  And how can your solar inverter last longer? Therefore, here are some nifty maintenance tips for solar inverters to last longer. 

We will also provide essential insights into your solar inverter’s maintenance, repair, and service information, which are significant in your solar power setup. 

Signs of Inverter Failure

While solar panels usually last 25 years or more, solar inverters tend to have a shorter lifespan. Even the best solar inverters typically have warranties lasting 10 to 12 years. After the warranty period, you should mentally prepare yourself for a replacement.  

Here are signs that your inverter may not be functioning correctly: 

Unusually High Power Bill: If your inverter isn’t generating enough energy, you’ll get more electricity from the grid. And it will result in a spike in utility costs. 

Error Messages: Error messages on the inverter’s display indicate a problem; contacting a certified solar technician is advisable to diagnose and address the issue. 

No Indicator Lights: A lack of status lights or the presence of yellow, red, or flashing lights often indicates an issue with your inverter. 

Solar Battery Doesn’t Charge: Some solar batteries rely on AC power from the inverter; it may signify inverter issues if the battery isn’t charging. 

Disconnected Appearance: It likely requires repair if the inverter seems unconnected or damaged in its connections. 

What Damages Inverters?

Several common issues can cause damage to your inverter: 


Inverters may become excessively hot during operation, especially in Australia’s harsh environment. It reduces energy production. Proper ventilation and cleaning of dust filters are essential to prevent overheating. 

Faulty Installation

Even professionals can make errors, including physical connections or programming components. Following the manufacturer’s guidelines during installation is crucial. 

Isolation Issue

Isolation issues can occur due to a short circuit in the circuitry. It will trigger an “isolation alarm” and reduce inverter performance. Cable damage, moisture, incorrect installation, and poor DC cable connections may contribute to this issue. 

Maximum Power-Point Tracking (MPPT) Problems

Inverters utilising MPPT may face problems when connected to different PV module strings. These issues can affect the inverter’s performance and require professional repair. 

Inverter Restarting Issues

If grid-related issues disrupt your solar power system, the inverter should restart automatically. However, you’ll need a service team or installer to restart it manually if it doesn’t. High-quality systems with 24/7 monitoring can help avoid this issue. 

What to Do If Your Solar Inverter Fails

If your inverter experiences issues, you have several options for resolution: 

Contact Your Solar Installation Company:  

Contacting the company that installed your solar system is helpful. They can assess and potentially repair or replace the inverter. 

Contact the Inverter Manufacturer:  

If the installer is no longer available, contact the manufacturer for assistance. They may send a technician or collaborate with a local solar company to address the problem. 

Consult a Trusted Solar Company:  

You can also contact an established and reputable solar company, like Solar Emporium, to resolve any inverter issues. Providing documentation from the installation can speed up the process. 

Maintenance Tips For Solar Inverters To Last Longer

Following these maintenance tips for your inverter is essential to ensure optimal performance from your solar power system. 


Ensure your inverter system’s installation is in a well-ventilated, dust-free environment. It would save you a lot of money. It may overheat when you install it in an area with no ventilation. The heat forms dew, which can lead to rust. Preventing heat, moisture, and dust will help your inverter system run more efficiently. 

Also, install your inverter sheltered to protect it from rain, snow, and direct sunlight. Environmental exposure can cause damage and reduce efficiency. Check for water flow and corrosion regularly. 

Overloading the Inverter

Refrain from overloading your system with electrical devices and appliances larger than capacity. As stated before, heat or flames can damage your inverter system and battery. So avoid any flame or heat around your inverter after installation to make your inverter last longer. 

Maintain Proper Ventilation

As the inverter converts DC electricity to AC, it generates heat. Keeping at least twelve inches of open space around the equipment is recommended to ensure proper airflow. Avoid blocking the inverter’s fan.  

Additionally, keep flammable items away from the inverter to prevent fire hazards. 

Clean the Air Intake Filter

Depending on the location of your inverter, the air intake filter can collect dust and debris over time. A dirty filter can hamper cooling and reduce the inverter’s efficiency. It is advisable to seek professional assistance cleaning the filter, as it may require disassembling some equipment. 

Check for Error Codes

While daily checks are unnecessary, periodic inspections are recommended to ensure everything functions properly. Look for any error codes or unusual lights on the inverter screen. If any abnormalities are detected, contact a professional to assess the situation. 

Utilise Solar Monitoring Technology

If your solar power system includes monitoring technology, such as a smartphone app, use it. This technology provides regular updates on your solar panels and inverter status.  

And it allows you to access customer service and technicians. However, it is still advisable to physically inspect the inverter regularly for any signs of trouble, as technology can occasionally encounter issues. 

Regular Inspection

Begin by visually inspecting your solar inverter. Look for any indications of physical damage, loose wires, or abnormal signs of wear and tear. Ensure that the inverter is clean and free from debris. Over time, dust, and dirt can accumulate and impact its performance. If necessary, gently clean it using a soft brush or cloth. 

Maintain Optimal Temperature

During operation, solar inverters can generate heat. Proper ventilation for the inverter to spread this heat effectively is necessary. Avoid installing it in direct sunlight or near other heat sources, as excessive heat can shorten lifespan. 

Secure Connections

Loose electrical connections can lead to inefficiencies and potential inverter failure. Regularly inspect and tighten all electrical connections, including DC and AC terminals. Exercise caution and adhere to safety guidelines when performing this task. 

Refer to the Manual

The manufacturer’s manual is a valuable resource for maintaining your solar inverter. It contains specific maintenance instructions and troubleshooting tips tailored to your particular model. Keep the manual easily accessible and follow the recommended maintenance schedule. 

Professional Inspections

While you can perform basic maintenance tasks, having a professional inspect your solar inverter at least once a year is advisable. They can identify potential issues that may not be evident during routine checks and ensure the safety and efficiency of your system. 

Check for Software Updates

Inverter manufacturers often release firmware updates to enhance performance and address potential issues. Regularly check for updates and install them as recommended by the manufacturer. Keeping your inverter’s software up-to-date can improve its longevity and efficiency. 

Make a Plan for Replacement of Damaged Parts

Solar inverters have a typical lifespan of 10 to 15 years. Consider replacing your inverter as it nears the end of its useful life to avoid unexpected system failures. Upgrading to a newer, more efficient model may improve your solar power system’s overall performance. 

In conclusion, maintaining a functioning solar inverter is crucial for an efficient solar power system. Regular maintenance, prompt, professional help, and access to monitoring services can help maximise the lifespan and performance of your inverter.
