2 80W 12-120V simple inverter project



The output of this inverter project is square wave  750ma max using 144 ohm load.


Load  must not include equipments with motor that operates in purely sinewave source of 50 or 60 Hz frequency .

the circuit is good in lighting like cfls and incandescent lamps. but ensure first that the load must not exceed the 90W for proper operation.



Resistor is parallel combination of three  27ohm 10W

transformer 12A   120V to 12V-0-12V

for more protection, provide 8A fuse and a switch in series to the battery
