Effectively Troubleshooting Common Inverter Issues

Dec 1, 2025

In a country like India, frequented by voltage fluctuations, power outages or load shedding, inverters are god-sent. The manufacture of general-purpose inverters revolutionised the power backup industry in the late 20th century. Soon, every home had a mini power station installed in some corner of the house, ready to switch into place during a power cut.

Apart from providing battery backup, they help stabilise the voltage being supplied to various home appliances. We have grown accustomed to a life made convenient by the advent of inverters. Naturally, we get a little stressed when this electricity stand-in begins to malfunction.

Inverter troubleshooting is just as easy and doable as owning a model. Like any other electrical appliance, it can run into trouble without notice. Understanding how to fix inverter problems is handy knowledge. It saves you panic as well as the additional expense of hiring an expert. Here are a few common inverter problems and solutions:

  1. Inverter Not Turning on

Is your inverter showing error when you try to turn it on? If your inverter does not turn on the way it usually does, it can be due of the couple of following reasons: 

  • The battery isn’t connected to the inverter
  • Wiring has been damaged
  • Inverter’s hardware has run into an issue
  • The battery is too weak to support turning on
  • An internal fuse has blown up

Ways to fix it:

  • Try restarting the inverter
  • Check the fuse/MCB for damage
  • Make sure the battery terminals are free of corrosion or rust
  • Get your hardware checked. Repair it in case of damage.
  • Replace the dead battery with a new functional one

  1. Overload

Every inverter owner is sure to encounter an inverter beeping problem. When one or multiple heavy-duty appliances are connected to the inverter, it can start beeping from the excess power load. Recognise that your inverter has exceeded its capacity and is bearing load far past its limit. Sometimes, attaching faulty appliances to the inverter connection can also make the alarm blare.

Ways to fix it:

  • Unplug a few appliances
  • Check for short-circuiting in the connected appliances
  • Inspect the wires
  • If the beeping persists, try restarting your inverter after reducing the load.

 

  1. Low Battery Backup

Although commonly noticed in older systems whose batteries have been strained from wear and tear, inverter batteries in new systems can drain quickly, too. Such a problem can arise due to:

  • Faulty battery device
  • Excessive power consumption in a short period of time
  • Low levels of electrolytes in the tubular batteries
  • Wear and Tear

Ways to fix it:

  • Get a faulty battery replaced with a tested functional one
  • Reduce the number of appliances connected to the inverter
  • Check the water levels. Replenish with electrolytes if required.
  • Replace the old battery with new ones

  1. An Overheated System

If your inverter is hot to the touch or does not cool down properly, there might be serious problems in the internal operation of the system. It’s best to tackle the issue with immediate attention. 

Reasons your system might be overheating:

  • Blockages in the vents 
  • Overcharging a battery
  • Malfunctioning or not working fan
  • Unusually high room temperatures
  • Internal faults in the device

Ways to fix it:

  • Clear out the vents to ensure free passage of air
  • Replace a defective fan
  • Move the system to moderate temperatures
  • Disconnect appliances and let the system rest
  • Check for visible signs of melted fuses 

  1. Faulty PCB

The PCB (Printed Circuit Board) is an internal hardware component in appliances that ensures the smooth functioning of all other connected parts. It is the neural network of the device and central to its proper functioning. The PCB might be damaged due to:

  • A component having fried internally
  • Frequent power surges
  • Defects in the device manufacturing
  • Choking of internal parts from dust

Ways to fix it:

  • Reset the device
  • Replace the PCB 
  • In case of a manufacturing defect, replace your complete device
  • If you’ve successfully done it before, clean the PCB of dust or dirt
  • Hire a professional to look into the inverter parts

Conclusion

Most households encounter one or multiple of these problems during the lifetime of an inverter. Often, though, inverter troubleshooting for common problems can be managed systematically, without cause for grave concern.

FAQ's

Why is my inverter tripping?

Inverters tend to trip due to power surges or from internal malfunctioning of the PCB. Sometimes it is accompanied by a burning smell or flicker of the display. Check the PCB of your inverter. In case you’re not a technician, contact one promptly.

Unless errors in functioning are visible, inverters do not require frequent health checkups. Monitoring the water level from time to time and a full servicing every 6-12 months is adequate to sustain the battery’s health.

Yes. It’s normal to monitor the electrolyte level of your battery yourself and pour distilled water when the system needs it. Make sure to wear gloves or avoid any physical contact with the liquid.
