Hello friends. I have purchased Luminous Inverter and ups for my home in 2013. Price of the set is very reasonable. It is very good in use and safe for use. Luminous Battery is very very good and long lasting back power. I am using this since 4 and half year and I never faced any problem with this. We have to care about battery water and timley cheking of its minimum level. You can use the water by purchase from market to pour in this. Comany gives a good response even if there any requirement. I got 3 years warranty of this set.Good and If you want to purchase a Inverter I advice to purchase this.
