Thank you for checking for this new innovation. One thing I want you to know is that ups( uninterrupted power supply) can be used as inverter. Is what Many of us don't have the idea of on what their ups can for them except short time back it does.

Note that due to the some good functionality of ups many inverters have been have ups mode to prevent interruption during power failure.

UPS has the following merit overr sachet inverters.
1. It regulates voltage during fluctuation
2. It provides quality power to load
3. It provides constant voltage
4 it serves as isolation btw mains and load

How to turn it into inverter for use
Step 1
Unscrew the ups casing
Step2
Locate the internal connected battery(ies) and disconneft them
Step3
Those two wires of black and red are your positive and negative
Step 5
Get a flex wire of black and red and connect them together
Step 6
Get any inverter battery of either 45ag,75ah, 100ah, 200ah as u can afford and connect them on it
Step 7
Get a battery charger plugged on wall socket to charge the battery
Step 8
Below is a picture of mine
This can save you cost instead of buying inverter . It is cheap and afordable
Suitable for a room , self contained , mini flat and 2bedroom flat.
Total of this cannot cost you more 40k, 50k, 60k,70k depending your battery choice.
