UPS Mode Vs Inverter Mode in Inverters
Inverter vs UPS Mode

We have a 800 VA Inverter running on 150 AH battery because in Nepal we face up to 16 hours of daily power cut. Students can’t study, factories are on loss, local entrepreneurs can’t do business. Us bloggers have to wait till power comes at night so that we can charge or laptop, phones etc. Even the telephone and internet (ADSL) goes dead after certain hours. It is because telecom company can’t even support such longer power cut. This is why most of the people use inverters in their home.

Inverter simply a power backup device that is just like a UPS which runs with bigger battery. In general understanding the UPS and Inverter are same. But there is a micro circuit difference between them which creates a huge change in their definition and working capability. To be clear UPS are recommended for providing backup to delicate electronic equipment. For example  like servers, computers, workstations that need continuous power.

The main difference between them is time interval in power switching. In Inverters when the mains go the 12 Volt or 48 Volt DC battery power is inverted to 240 Volt or 110 Volt AC using inverter circuit. This change takes around some milliseconds but the same transition happens in a fraction of time taken by inverter.

This small time delay in electronic circuit causes a large havoc for continuous supply demanding devices. Computers, big TVs and servers restart because of small time interval of no power. So if you want continuous power without any interruption then you should turn into UPS mode.

Details on Inverter vs UPS Mode

UPS mode is used when someone requires continuous supply of good electricity. There is a challenge in this process. The system requires good mains supply to maintain the status quo. Many places don’t have good supply of mains. It means that the voltage fluctuates in huge range. These types of system usually requires good electricity supply for health working.

More battery is used to supply electricity during UPS mode. So the biggest con is if the mains don’t supply standard 220 V-240 V or 110 V for charging, it won’t take input. This the UPS mode will cause to drain the battery. In contrast, 140 V to 240 V is also accepted in Inverter mode which is acceptable. So you will have to compromise your battery because UPS mode will reduce the battery life significantly.

After all the choice is yours if you want uninterrupted power supply for delicate electronic devices then UPS mode is the best choice but if you use household devices like bulb, fans etc then Inverter mode is the recommended because you will save the battery for long time.


  1. This is a old post but . If you want to run on UPS mode while charging at 140 V to 240 V . You just need to plug the inverter into a Voltage Stabilizer .. ( Not sure how safe it is .. but i am running this setup and its working wonders )
