Essentially this is simply what solar panels have done for ages, feed back electricity to the grid, sure it's not through a power outlet but essentially it connects to the grid in a similar way.
What's new is cheap and ubiquitous micro-inverters. Before it wasn't worth putting a $800 inverter on a small 2-panel 600 or 800 installation. Now with micro inverters being so cheap, this tech becomes viable. And with loads so limited (less than a microwave) the regulation is equally light to allow this convenient plug-in solution.
