I ended up buying a 2.5Kva Jasco Generator for almost 26,000/- its Chinese and runs on Natural Gas mostly, without any issue, just have to start on petrol thts not an issue really when u have self start system..
Since I live in a flat the noise is an issue for the neighbors thts why I refrain from running it all the time.
Best solution for ppl living in flats would be to buy the UPS and Generator both if they can afford it.. A bigger UPS so they can run PC and other stuff for 2 hours with ease and a small generator incase electricity forgets when to come home
But for those who cant a generator is a better option than UPS in my opinion because they are pretty reliable in the long run and cost of Gas is negligible..
@ BigNate
Those briefcase type generators are pretty ear friendly, I saw a Honda 1 Kva for 33,000 the dealer said its Honda China which again gives u second thought, but they cant be run on Gas thts a let down but if u r willing to run on petrol they are good option
But again as I said UPS + Generator is the best option available
