I purchased Luminous Invertor 650 3 months back from a retail shop in Lakshmi Nagar Delhi at the cost of 2700, after 3 months of using this I find it is nice inverter in this range. It comes up with 24 months warranty and works on square wave power technology.
It is very efficient and consume less power.As a backup I use it to run my Invertor AC, TV, Fan, LED bulbs etc. It works perfectly without any fluctuation.
Specification-
-Support 12 Volt battery
-Net weight - 7 Kg
- It has 3 stage charging
So I think this nice product to have for a small family.
Thanks
