Experimental work | Using an optocoupler for AC polarity detection

In PV grid connected inverter, in order to inject the current at unity power factor we need to know the polarity of the grid . To do so various solutions exists. Among these solutions is the use of optocoupler. I have verified the use of 4N26/4N37 for the said purpose. The circuit is very simple and its working is given below. ...
