Easy Tips to check Inverter Battery Heating Problem

Ever witnessed unusual heating of Inverter Battery at home? Although most devices heat up while working, but sometimes overheating causes panic among consumers. As we have already discussed that inverter works round the clock in our previous blog, it is important to keep a thorough check on its working. While witnessing a mild heating up of inverter battery is common sight, but make sure it doesn’t get unusually high.

In this blog, we will be discussing some easy tips to keep a check on heating of inverter batteries and some DIY steps to keep this issue at bay.

Let’s Discuss Some Tips To Check Inverter Heating


Check the battery selection switch at the back of Luminous Inverter. At the back of Luminous Inverter there is a switch which lets you to select the inverter operations basis the selected battery type. Choose the option according to the type of battery attached with the inverter. Refer below table for the same:

Battery Type Switch Selection
Tubular TUB
Flat Plate FLAT
Local LOC

Inverter tend to heat up if switch selection is different from the type of battery attached with the inverter.


Check the charging current jumper on your Luminous Inverter. At the back of Luminous inverter, there is a switch of current jumper, if you have selected higher current jumper against the low Ah battery it will lead to heating up of battery. Select the switch based on the below table

Battery Capacity Charging current selection Jumper position
80Ah- 100Ah L
120Ah- 150Ah M
165Ah- 225Ah H

IExample : If you have attached 80Ah battery with the inverter, make sure current jumper switch is on L and not M or H.


In case of No cut-off of charging voltage beyond the upper charging limit it may lead to Inverter failure.

Battery Check point

Battery problem majorly arises due to internal issues like:

•   Short circuit

•    Loose inter-connection.

•    Contamination from external objects.

•    Being discharged then being undercharged for a long time makes the battery sulphated from inside.This is due to battery is not charged properly due to regular power cuts

•    Use of wrong electrolyte or contaminated water

For HKVA inverter where high voltage battery banks are used, using battery of different models, capacity and sizes may lead to overheating of the weakest battery.

Hope these tips will help you to diagnose and take corrective action in case of any heating problem in you power backup system. For more such content visit: https://www.luminousindia.com/
