PURE SINE WAVE INVERTER WITH LED AND LCD

PURE SINE WAVE INVERTER WITH LED AND LCD

The inverter PCB is easy to assemble by following the label of the components to be inserted. The choice of the voltage to be used to power the inverter ranging from 12v to 96v depends on kva you are designing. for any setup,  a 12v relay is to be used. 
The featuring M.C.U are the Microchip PIC16F72A  and  PIC16F876A
