Definition – Inverter and UPS
When I mention UPS, I am not talking about the popular parcel delivery company. UPS stands for uninterrupted power supply, and it’s an electric device with an inbuilt battery used to backup power in the case of a sudden outage. It is commonly found in an office where it is used to backup a computer device. Some of its characteristics are, charging, surge protection, and short backup time.

An inverter is an electronic device that converts DC ( direct current) power to AC ( alternate current) power or vice versa depending on the design. We have frequency inverters and solar inverters but I would be discussing solar inverters. It does not generate current, it converts.
Why should I buy an Inverter Instead of a UPS?
| Attributes | UPS | INVERTER |
|---|---|---|
| Definition | An Electric device that provides backup power | An Electronic device that converts unidirectional current into bidirectional current |
| Main Function | Power Storage | Current conversion |
| Switch over timing | Instantly | Delay |
| Types | An Electronic device that converts unidirectional current into the bidirectional current | Offline, Online, and Standby |
| Connection | directly connected to the appliance | Its connected to the battery and the appliance |
| Backup Power | Electricity | Electronics |
| Backup timing | Short | Long |
| Voltage fluctuation | Nil | Yes |
| Circuit type | Inverter and controller | Battery |
| Cost | More | Less |
| USE | Stand-alone and Grid tie | It’s connected to the battery and the appliance |
Conclusion
It is my opinion that the UPS is more effective because of its ability to backup appliances without delay and fluctuations. While the inverter is more cost-effective because of its flexible nature like the ability to backup more appliances over a longer period of time and it is not restricted to any type of primary power source. As you already know, it is just a medium between the primary power source and the batteries. The batteries store energy that comes into use during an outage.
Depending on what needs to be taken care of, you are most like going to make a good choice from the table above. For a less complex connection where you would need to backup a particular appliance for a limited period of time, I would recommend the UPS.
When you have a bigger picture in mind like backing up a house which would require a complex connection. With a longer backup time, and multiple primary power sources, I would recommend an inverter.
