Luminous zelio 1100 VA shine is the best inveter compered to other brands.i bought it 2 years ago .it gives me total satisfaction .this inveter comes with two year warnty period but I did not have any manufacthring problem in it.
Luminous Zelio has great battary back up .its battary back is 7-8 hours after full charge which is very long lasting back up.
I bought it about 10000 rupees .which is not very much in this class of UPS.
Customer care support of Luminous brand is quit good.its durablity is very good no doubt it.
So want to buy do not think so much.
