9. Damaged Inverter Part

In case there is a damaged component in your inverter, be certain you will hear an inverter noise whenever the model is in use. If you are the victim of this circumstance, you might need to seek the help of a professional technician so as to avert this problem.

10. A Failed Inverter’s Self-Test

Most inverters usually perform a self-test after every 2 weeks. Ideally, this test is done in order to check your battery’s integrity. Although there are instances when the test goes on smoothly, there are moments it might fail.

Suppose the inverter fails this test, it shows that your battery is dead and needs to be replaced as soon as possible. If this happens, your inverter will start to make a beeping noise after every 4 to 5 hours.

Other Reasons Why Your Inverter Might Start Clicking Bring Inverter Noise:

Apart from the reasons that we have discussed above, here are other additional reasons why your inverter is producing a clicking sound:

• Your inverter’s motor has burned out.
• Your inverter has a loose wire inside it.
• Presence of a damaged cable.
• You have placed your inverter in a place that has poor ventilation.
• Your inverter has old or bad capacitors.
