Its is very useful Inverter. Its capacity is very high. It improves the battery life. It has several types of indicator which has thier own functions like indicating wheter electricity is available or not, It is on battery or supplied electricity, fuse is gone or not, voltage is high or low, battery is charging or charged.
It has been a year since I bought this UPS It works very fine. It prevents the home appliances from sudden change is voltage attacks. It chargea the battery very efficiently. It has more capacity than usual. Once established forget about maintenance. It is a life saver during night and summers.
