I am been facing the electricity problem in my town. So decided to but an luminous inverter. I had also looked for other inverters. But their cost were too high.
Thus I later decided to buy an liminous inverter. One of my friend have the same at his home since 6 months. And it works fine for him. Well on this inverter my Desktop, TV, Refrigerator, Washing Machine etc works fine with no current fluctuation. Battery charging commences even at as low as 110V Mains AC.
