Tips: How does the on-grid inverter work?
Simply the inverter has a computer module that senses the grid AC voltage waveform and continuously measures all its parameters instantly like the voltage, frequency…etc. and then starts to inject the AC current, so that the inverter keeps its output voltage to be slightly higher than grid voltage all the time. At the same time, the inverter must have anti islanding feature which quickly disconnects it if the grid power system shuts down for any reason, to protect itself from feeding uncontrollable loads "may be higher capacity" and protect personnel who were sent to troubleshot the power grid.
