As I am using sukam sine wave inverter falcon plus 850VA since 7 years without any fault it is working fine and I have replaced 2 batteries on that, it is pure sine wave inverter and it has smart charging features which increase the battery life more than its rated life. So I would say that sukam is the best technology based organisation which is launching best products every year which fullfill the customers satisfaction. We are proud of sukam brand. I am very happy to using sukam Inverter.
Thank You.
