I bought a new inverter for my home because in India there are lot of electricity cuts in summer season.battery pack up is very good. It works for long hours after electricity cut.its ups have good features like. Charging indicator, baterry Low indicators, etc.before buying this product I had done little research on inverter, which conclude that luminous is the best one in price, its working ability for more hours, very compatible, dont took too much space in House as compare to other inverter brand's in market, and luminous provide me free service of installing it. Warranty is for long time period, overall I'm satisfied with service of luminous and also satisfied with this product, well done luminous
