I understand DC power more than AC power. I know that given multiple DC power generators, easiest way to sum them is by connecting them in series. In paralel you'd need every generator circuit to protect itself from reverse current coming from other generators.
But I'm currently learning about solar PV systems and noticed that 'net metering' is just us putting our inverter paralel to the grid.
Thing is I am really not knowledgeable enough about AC to make this oversimplification – is it really that easy?
