My father bought a Luminous Zelio 1100 Inverter with 220AH battery. It worked fine for 8 days and on the 8th day it stopped charging. It started making a ticking noise and the lights of entire house were fluctuating due to this. We had to make several calls to Luminous before anyone visited and fixed the problem. We had high hopes from Luminous and now the product going bad in mere 8 days just shakes our trust on the brand.
