Hello guys. I have buied that inverter ine year ago. I have used it a lot and I have never see any type of complain in them except the the cleaning and servicing of adjust fan, which basically needed in any machine. With its inherent state of the art charging technology, this unit enhances the battery life. It is very use full in small family like 3-5 members in a family. It can pickup the load of two fan and 3 tube light together. The inverter uses minimum Input Voltage between 185 - 265V and Maximum Input Voltage ranging from 105V to 285V. This smart heavy duty home inverter is offered to you at a very reasonable price. And all these specifications make them very usefull and effective for a small family.
