Luminous Inverter and UPS is the best power back up system available in the market. I am using it from the fast two year, it has strong durability power so that it saves money towards repairing inverter repeatedly. Usage of this inverter is also easy. Luminous provided me good service till now and I hope in future also. Luminous inverter comes with warranty so that it saves your maintenance cost to some little time period. So my overall review about Luminous inverter is "Better".
