Luminous inverter and UPS is a nice product presented by luminous in the market which is meeting the ever increasing demands of people from past years.I have been using this product from last 3 years and I have never complained about it.It has a very strong battery backup as compared to other inverters, as battery is the main asset of inverter system.It has high durability and can be charged on both low and high supply of power depending upon the choice.
