I use luminous zelio 1100VA Sine Wave home UPS inverter and I find it quite reliable and its usability is really awesome.
No doubt about the looks it has.
It gives a backup time upto 8hrs and this is a very good feature according to me.
It also comes with a 2year warranty with makes it more reliable than any inverter.
The output voltage is around 220-230V which is enough for our usage.
The cost is Rs.10, 000 which is for its very good performace and reliability.
I recommend you this inverter if you are searching for a good and reliable inverter ahead.
