We bought this inverter a year ago.It takes a long time to recharge the battery and also doesn’t give a good backup .The battery doesnt have any problem.The inverter charge the battery too slowly thats the main reason .And now it stops charging the battery.i dont knw why.I have took this inverter two times to the shop from where I bought it.They made it good and aftr a month it again becomes bad.I have wasted too much money on this .So guys dont buy this .go for luminous or microtek
