When your solar inverter makes a clicking sound, there is usually no need to worry. This is a common problem that can often be resolved quickly and easily. There can be several reasons for the inverter to make a clicking sound, including inverter overload, the need for resetting, or a problem with the AC coupler. If there is a clicking sound accompanied by flashing indicator lights on the inverter, it may indicate a serious error. While noise issues with solar inverters can be unpleasant, there are ways to address buzzing, clicking, or other types of noise. Let’s explore the reasons behind these issues.
How to Fix a Noisy Inverter? One common cause of noise in an inverter is when the inverter load exceeds its capacity. The noise from an inverter is not only unpleasant but also often leads to operational issues. Therefore, it is wise to regularly check if the inverter is making noise and if noise is detected, try to find the root cause of the problem. Here are some methods to fix a noisy inverter: Check battery status When the inverter starts making noise, it is very important to check the battery first. If the battery is in good condition, the problem may lie with the inverter itself. So check the battery first. In some cases, a low-power battery can generate a lot of noise and affect the performance of the inverter.
Dust or debris in the fan cover can increase noise levels and cause damage. Regularly check the fan for wear or damage and replace it if necessary.
Warning: Never operate the inverter without a fan installed. If the fan is missing or damaged, it may cause the inverter to overheat and be damaged. Regularly clean the inverter. Clean the inverter with a soft brush regularly to prevent dirt from adhering to internal components, resulting in more frequent vibration and greater noise when the inverter is running. Note: When cleaning the inverter, unplug the power cord and turn off the switch to ensure the device is powerless. Clean the motor unit. The motor unit is a common noise source in the inverter. Dust and other foreign matter accumulated on the motor windings often cause a loud buzzing sound. To clean the motor, remove the cable connector, blow away any loose particles with an air compressor, and let the motor cool before reinstalling the cable. Note: Never use water or other liquids to clean the inverter. Any moisture entering the device may cause damage. Cable inspection. The inverter transmits power from the solar panel through cables. Over time, these cables may be damaged, resulting in voltage drop or short circuit, which can cause the inverter to emit a burnt smell or smoke. If you suspect cable damage, consider replacing it as soon as possible to avoid further damage and potential danger. How to identify whether inverter noise is dangerous. It is difficult to determine whether the noise emitted by the inverter is dangerous. Some sounds are normal, while others may indicate a malfunction. If the noise comes from inside the inverter, it is usually normal. If the noise comes from outside, it may be a sign of a fault. Here are some common sounds and their meanings: Buzzing or humming: This is usually caused by the operation of the internal fan of the inverter and is a normal phenomenon. You should not hear this noise when the system is unloaded. Clicking/cracking sound: This may also be caused by the operation of the internal fan of the inverter. If it is only heard when the system is unloaded, it is a normal phenomenon. If this occurs when the system is loaded, it may be due to insufficient ventilation in the attic or confined space where the solar panels are installed, resulting in overheating. Final suggestion. The clicking sound emitted by the solar inverter is usually caused by loose wires. If all other possible causes are excluded, check the wire connections and tighten them if necessary. If the problem persists and you cannot solve it yourself, you should contact a solar technician for inspection.
