An inverter is a very important device which everyone must own for their homes as well as the offices. This device helps you to get electricity in the most important appliances when there is no power otherwise. But what if your inverter encounters some problems and thus doesn’t work properly? Well this could lead to several issues such as no lights, no microwave power and several others. Thus it is best to know the common inverter problems along with their solutions so that you can resolve the issues yourself. They are given as follows:
1. Inverter not turning on
Inverter not turning on is one of the most common inverter problems. The few possible causes for the same include tripped inverter, battery disconnected, battery terminals loose, weak battery, discharged battery or battery terminals are reversed etc. In case the power switch is defective you must take it to service centre for repair. In case of faulty battery, replace it however if the inverter is tripped then you may need to press the trip reset button given on the device to reset it. If your battery has gone weak, then it is advisable that you charge it for a few hours. Else if it is old, then it is a good idea to replace it altogether. if the terminals of the battery are loose, check them for corrosion and give them a good cleaning before clamping them firmly.
2. Battery is not getting charged
Another one of the common inverter problems is battery not getting charged. One reason for this could be a dead battery and in this case the battery must be replaced. Other possible causes for this could be burnt rectifiers, melted fuses and loose battery connection. In these cases, you must either get professional help or check battery terminals for corrosion.

3. Shortened backup time
Another problem which an inverter can encounter is shortened backup time. This could be due to too much power consumption and in such a case, you must remove the extra load. If battery is not properly charged, then even in that case this problem could crop up. Also, if the battery has lost electrolyte, then the backup time may become shortened. In this case, top up battery with distilled water regularly. remember that the water level must be maintained between the maximum and minimum water limit.
4. Power inverter working in just the inverter mode
If this problem comes up, then either the input is not connected or the fuse must have melted. Check the power cable and change the fuse respectively for the above given reasons for a power inverter working just in the inverter mode. However, if the cause is input protector being effective, then you must reset it. An input protector is basically a protector circuit which saves the inverter in case of high voltage conditions. Some other causes for this common inverter problem include low input and high input etc. What happens is that in case of low input, the Inverter does not switch to main power supply and hence works only in inverter mode. you may need to make sure that you choose a wide range from the UPS if this is the reason for the unit working in inverter mode only. You can also get a stabilizer installed to fix the issue of voltage.
5. Alarm beeping continuously
A lot of times, the alarm of the inverter may keep beeping continuously. In such a case, the possible cause could be either overload on the inverter or a stuck cooling fan. Disconnect all the extra load in case of overload. If the problem still doesn’t get resolved, then you may have to take the inverter to the service centre or contact a professional for help. Every inverter has a cooling fan which needs to run as long as the unit is operating. if the cooling fan is not able to maintain a temperature cool enough for safe working, the inverter will shut off automatically or it will give out an audible alarm to inform you that the device needs to be turned off. Similarly, if the fan gets stuck due to some reason and is not able to cool off the inverter, the unit will give out an alarm so as to notify you to shut it off.
6. Power inverter LCD displays false codes
Another common problem related to inverters which you may experience is LCD displaying false codes. In this case, either there is some internal problem in which the inverter circuit may need to be replaced or there is an external issue. If the issue is external, then you may need to check the battery cables, the output and input wires and load etc.

7. Noise coming out from Power inverter
Sometimes, you may also hear some noises coming out from your power inverter. It is important to know that every inverter gives out some wind noise which is normal. However if you hear the noise from the fan then your fan may need some cleaning through professionals. In some of these cases, the fan may need to be replaced as well to solve the issue.
Now that you know the various common inverter problems and their solutions, you can solve the issues yourself at home. However if the problem is beyond your comprehension, then you can contact a professional through Mr Right for inverter not working.

I appreciate you sharing common inverter problems and their solutions! With this blog at my fingertips, I will be able to solve most of my problems!
When my growatt spf6000tdvm is on SBU in parameter 1, inverter woks fine through all day. But at nights, it begins to fluctuate voltage on inverter, until I change it from SBU and put on SOL. The problem is just on SBU at nights. It’s turn off my refrigerator and even my a/c inverter in bedroom give me P1 (low voltage) code because that fluctuation on solar inverter.
My 20kwh lifepo4, 200ah batteries are in very good shape. Does anybody figures it out what is could happening?
very clear and good article easy to understand. Thank you
