Microtek inverter is the most trustable inverter.I am using it from last 4 years and still its working fine.Never stopped working uptil now.And it save power also by automatically disconecting when battery full charged to prevent battery from overcharging.There are indicators given which notify us about fuse, battery discharged and when battery discharged a sound come which is helpful to know that battery is fully discharged.And when battery gets fully charged than also it indicated.All an all its the best inverter I would say.I recommend it to buy without second thought
