Why do solar inverters fail due to overheating?

Electrical components are highly sensitive to temperatures, and if the maximum operating temperature is reached, it may lead to a reduction in electricity production.

Solar power systems comprise of solar panels, inverters, batteries and a meter. As long as the solar PV system is installed properly, they remain low-maintenance devices. Electricity is generated by the solar panels while the solar inverters convert DC electricity to AC electricity to power the household appliances.

Solar inverters have more electrical components than solar panels. And they are much more sensitive to heat and equipment failure.

How Long Do Solar Inverters Last?

String solar inverters have a life expectancy of 10-15 years and micro inverters can last for 20-25 years.

Although they are rated to last for decades, many factors can affect the performance of the inverters such as:

Heat
Faulty installation
Humidity
Poor maintenance

Why Do Solar Inverters Fail?

Overheating: Electrical components are highly sensitive to temperatures. If the maximum operating temperature is reached, it may lead to a reduction in electricity production. It is important to clean the dust filters regularly and ensure that the inverter has open airflow.

Grid Fault: High or low voltage due to a grid fault could prevent the inverter from working. Circuit breakers or fuses can be used to prevent the inverter from failure due to high voltage.

Maximum Power Point Tracking (MPPT): Solar panels generate different voltages – it is important to get the maximum efficiency irrespective of the different voltage levels. MPPT algorithms extract the maximum power from the solar panels. The MPPT tracker adjusts itself constantly to keep the solar panels at their Maximum Power Point. If you are experiencing reduced output, it could be due to a fault in the MPPT module.

Faulty Installation: A very common reason for failure in the solar inverter is faulty installation. If the solar panels are not matched with the inverter capacity, your inverter will not work efficiently. As a rule of thumb, your solar panel capacity should be up to 133% of the inverter capacity. For example, if you are using a 4 kW solar panel, your inverter capacity should be 3kW. If you are using a 6 kW solar panel, your inverter capacity should be 4.5 kW. Solar panels do not generate the power they are rated for

Fault codes: If your inverter is not working properly, it might show the error via a fault code. Refer to the inverter manual to troubleshoot the problem. Alternatively, you can see our troubleshooting guide for solar inverters.

  Damien P from Fallon Solutions was excellent from start to finish.

I was running about ten minutes late when he arrived, and he was kind enough to wait for me, which I really appreciated. Once I got there, he came straight in, got down to business and took the time to properly understand the issue.

Damien was extremely thorough, checking the meter, switchboards and even getting up into the ceiling to locate the fuses and trace the problem. He clearly explained what the issue was, what would be required to fix it, and organised a quote on site to be sent through to the landlord for approval.

He then worked with me to find a suitable date and time to come back and have everything rectified.

The whole process was smooth, friendly and professional. Damien was helpful, informative and clearly knows his stuff. I really appreciated the level of care and professionalism and would happily recommend him and Fallon Solutions.

  Chris Radcliffe from Fallon Sollutions, this morning was so excellent at his job.  He was very knowledgeable about every detail that caused my washing machine to flood and malfunction.

He went the extra mile and pumped all the dirty water out as well, while making me feel listened to, important and valued.

He was super friendly too.

I highly recommend Chris and hope to see him again if I  need to.
