    If you build according to diagram it should be work well.

    what is sec coil output in AC ? and what was the input voltage. if your home electricity voltage is low then 220 V then you have to do some thing for it.

    It is very useful project for the beginners and hobbyists.
    I think you will have to add one more D1047 or D313 transistor as darlington pair on both heat-sink plates to the transistors then this inverter cercuit will work perfectly.And if you want to charge battery add 4 diode of 6 amp on each heat-sink emitter to collector of transistor.And if you add relay it will automatically charge the battery.But be careful while charging battery with it. it will over charge your battery if you are charging battery with it for a long time.Check battery voltage with digital meter if it is showing more then 14 volts stop charging battery otherwise battery will be over charged.
    I am From Sialkot and I love electronics.

    @Ali Muhammad Thanks.
    I did’nt experiment with PN Junction Diode.
    the main purpose of resistor is to start inverter, for 1500 watt inverter 1k ohm resistor is good to starts inverter but you can try different resistors.
