An inverter is an essential appliance which is present in almost all homes and offices across the world. This device powers our essential appliances in case of power cuts by providing back up. Inverters run on batteries which need to be maintained properly along with the rest of the unit. If not, then there are certain problems that can crop up in these devices. One of the problems which many inverter users report is inverter beeping continuously. The following are the possible causes and solutions for inverter beeping continuously that might prove useful.

1. The inverter is operating on battery power

REASON: One of the common reasons for inverter beeping continuously is it running or operating on battery power.  The beeping or alarm basically points towards the fact that the unit is transferred from on line operation to battery operation.

SOLUTION: In this situation, the battery power supplied outlets have now become battery powered.

2. The inverter is in low battery condition

REASON: Another reason for the beeping sound could be an alarm for low battery.  This means the device may soon turn down and is an indication for you to charge the battery.  In order to protect the device’s batteries from discharging too much, the inverter will be forced to shut down.  Generally, the alarm rings for 2 minutes before shutting down but this time period can be changed too.

SOLUTION: In order to stop the beeping sound or alarm, you must recharge your inverter as soon as possible. This might take a few hours time.

3. Capacity overload

REASON:  Another common cause for inverter beeping continuously is capacity overload.  If the device is in overload condition then you will hear the alarm and must remove the non essential equipment.  The alarm will keep ringing until you remove the extra load.

SOLUTION: You must try and buy an inverter of the right size and capacity to avoid the beeping issue due to overload. Else you can also try removing some extra load of possible.

4. Inverter must have failed a self test

REASON: Though not common, but a possible reason for the beeping could be that the inverter must have failed a self test.  Most inverters perform a self test every 2 weeks to check the integrity of the battery.  If it fails in the test then this means that the battery may be near its end and needs to be replaced.

SOLUTION: This means you must replace the battery within the next 2-4 weeks.

These were the top most common reasons for inverter beeping continuously. Well if you are someone who is facing the same problem, then you must try and find a solution based on the above given causes. However each beeping sound is different and indicates a different issue. For example, continuous beeping indications battery being too low whereas a constant solid beeping tone is an indicator of capacity overload. Thus you may need to learn the various tones and their meanings to find a quick resolution of the problem.  If you wish to contact a professional to help you with inverter noise problem, you can reach out to Mr Right.

Super long beeps. Now, it’s beeping twice with the 2nd beep holding for about 3 seconds and continuously repeating What could be the issue? Thanks ahead and thank YOU once again Mr. Right 👍

    Thanks for pointing out the reasons of this inverter cause. Well, I have been using a Microtek inverter for more than 10 years without a single problem. You can say I am the winner.

    When the Microtek inverter was in its warranty period, I had to call the serviceman because the UPS function was not working properly, the serviceman came on time and replaced the transformer. After the transformer replacement, the inverter has been giving the best performance as of now. But it is a modified sine wave inverter. I am planning to change it to a pure sine wave for the good quality electricity.

    I have an eliminator 400 watt inverter mobile power outlet. Open the box hooked it up to my charged battery. Consistent alarm when powering on. Same procedure done in my vehicle 12 v plug in and consistent alarm again. Does the inverter need a charging mode time itself? Out of the box I thought this was a plug in and power up instantly device.

    I bought an off grid inverter of 2000W.
    When I switch it on, the terminals of the battery (140 ah) gives me an electric shot. the terminals of the battery have very large current. But the battery is 12V. When switch off the inverter then no current on terminals. What is the problem with inverter?

      Hi Mr Right
      My inverter now makes a continuous noise after discharging my battery due to low power supply from grid.what could be faulty, battery still charging from that little power

    If you are using the inverter without the engine running it will probably keep doing what doing.. it’s not an app. If you do have vehicle running and it does same thing. Check connections make sure some of the cable insulation has not interrupted power.

    I have a power converter 410w, the battery I’m using is fully charged and we ran it for about an hour an a half with a small wat fan and a phone charger the box claims that it can run two 12v cords and a USB port at once. It began beeping and now it wont run but for 2 or less minutes an itll start beeping again. The contact number for the power converter is faulty so I’ve no ideas what to do.

    Hi. My inverter keeps beeping even though the battery is full. On my 24v400A bank system, it reads 25.2v
    Something funny happens, when I disconnect a terminal from the inverter, and I attempt to power it,, it tries to come on (I guess stored charge in the capacitor.) but when I connect that terminal back, I see a huge spark almost like I’m bridging the battery.
    I opened the inverter up and all looks good. Please what do I do?
