Hi friends,
In a metro city, there are no power cuts at all except for rare emergencies. But when I am at my native place in South India, often there is routine load-shedding and power outages.
To overcome this problem, I have made an inverter circuit which draws 9.4 volts from 2 Solar Panels and drives a Transformer giving 240 Volts AC power. The direct output from a single solar panel can be used to charge a mobile phone / USB-charging device directly. It has a Nokia-type pin provision too.
This works as long as there is bright sunlight falling on the panels. The output from the inverter is enough for a 40Watts tubelight, a table-fan, a small tv or a laptop. Also if we add one more panel and make few changes in the circuit, a car battery of 12V can be charged and used to drive the transformer to power devices when there is no sunlight.
