4 Common Reasons Inverters Fail During Summer (And How to Avoid Them)

Summers in India are no joke. The heat gets extreme. Power cuts become more frequent. Everyone looks for cool air and cold water. And that’s when inverters become lifesavers.

But there’s a problem. Just when you need them the most, many inverters stop working. They either shut down suddenly or stop giving backup. Sometimes they don’t even charge properly.

If you have experienced such issues, don’t fret. This is a typical problem during summer. Now, let's find out from this blog about the reasons why an inverter doesn’t work well during the hot season and how you can bypass that.

Inverters Failing to Perform During Summers: Reasons and How to Avoid It?

You will encounter many reasons why all inverters do not function well during the hot summer days. However, there are also certain ways to dodge such issues:

1. Overheating

This is the number one reason inverters fail in summer. When it’s 40°C outside, the inverter also gets hotter while charging and discharging. Too much heat can damage the internal components.

Signs of overheating:

• The inverter shuts down suddenly.
  
  

• It becomes too hot to touch.
  
  

• It stops charging the battery.
  
  

• It makes a buzzing sound.
  

How to detour:

• Keep your inverter in a cool, shaded area.
  
  

• Never place it in direct sunlight.
  
  

• Ensure there’s good airflow around it.
  
  

• Keep it away from walls and other heat sources.
  
  

• Use a fan in the room if needed.
  

Remember, machines also get tired in the heat. Help your inverter stay cool to work well.

2. Poor Ventilation

Inverters and batteries release heat when they work. If you keep them in a closed cabinet or a tight space, that heat gets trapped. This causes overheating and early failure.

Where people go wrong:

• Keeping the inverter under the stairs or inside a wooden cabinet.
  
  

• Blocking the air vents.
  
  

• Placing items on top of the battery or inverter.
  

How to avoid:

• Make sure to place the inverter and the best inverter battery in a space that is airy and open.

  
  

• Do not try to cover up the vents or try to place things right above them.

  
  
  

• Keep the area clean and dust-free.
  
  

3. High Power Load

In summer, we use more electrical items. This puts extra pressure on the inverter. If you run too many devices together, the inverter gets overloaded. This can cause failure or shorten its life.

Common mistakes:

• Connecting the AC to the inverter.
  
  

• Running multiple fans and appliances at once.
  
  

• Not knowing the inverter’s power limit.
  

How to avoid:

• Know your inverter’s capacity (VA rating).
  
  

• Check the wattage of your devices.
  
  

• Only connect essential items during a power cut.
  
  

• Avoid running heavy appliances unless your inverter is made for it.
  

Using an inverter beyond its capacity is like forcing a bike to pull a truck.

4. Battery Water Drying Up

In summer, battery water evaporates quickly. When the water level becomes much lower, the battery will not charge well and will also not discharge correctly. This causes backup failure.

What you may notice:

• Low backup time.
  
  

• Charging stops midway.
  
  

• The battery gets hot.
  
  

• Unusual sounds from the battery.
  

How to avoid:

• Check the water level every 30–45 days.
  
  

• Top up only with distilled water.
  
  

• Don’t use tap or filtered water.
  
  

• Never overfill the battery.
  

The low water level is like low blood pressure for the battery. Keep it in check.

5. Loose or Rusty Battery Terminals

All battery terminals become rusty, particularly during hot or humid conditions. Erosion breaks the link between the battery and the inverter, which can lead to impulsive shutdowns or poor charging.

What to look for:

• White or green powder near the terminals.
  
  

• Loose battery wires.
  
  

• The inverter is beeping randomly.
  

How to avoid:

• Clean terminals with a soft brush and baking soda mix.
  
  

• Tighten all connections properly.
  
  

• Apply petroleum jelly to prevent rust.

A healthy battery is like the heart of your inverter. Keep it strong.

Microtek: A Brand That Understands Indian Summers

When it comes to power backup, not all inverters are equal. You need a system built for Indian weather, especially the brutal summer heat. That’s where Microtek comes in.
