1. Inverter 500W 12V to 220V By IC 4047+2N3055
Using this circuit you can convert the 12V dc in to the 220V Ac. In this
circuit 4047 is use to generate the square wave of 50hz and amplify the
current and then amplify the voltage by using the step transformer.

How to calculate transformer rating
The basic formula is P=VI and between input output of the
transformer we have
1. Battery for this projects.
If you need 500watt output inverter your battery must be 45Ah. (500w/12V = 41A).
Maximum current for 1 hour.
2.The solar battery charger( 18 volts solar voltage)
Full sunrise power on day about 5 hour.
So you need current from the solar is (45A/5hour = 9A)
or 9A x 18V = 160 watts.
