Nowadays there is no power supply to our homes for many numbers of days due to natural calamities. This requires a technology that may run the tube lights and fans, by using battery means and so there will be no darkness at any areas and anytime. Normally inverters in combination with battery are used as backup power. But these inverters are larger in size and weight. Also, the efficiency of inverters is about 60% only and with the upcoming technologies we can minimize the size, with an increase in the efficiency of the inverters greatly. Micro inverter is the key for next generation inverters. They are in the size of a person‟s palm and weighs less than 2kg. They have an efficiency of about 95% and can be used anywhere, even with the help of bike or car batteries. One micro inverter has the capacity to supply 200Watts which is enough to supply the basic equipment in our house.
