i'd be careful telling someone that they don't know about power grids. All the microgrids you describe provide basic needs. None power serious industry anywhere. Batteries are a good solution for certain situations, not as a fix-all. All the batteries in the world can power a large power system like California or Quebec for minutes. That's right - minutes.
