Could have the terminology wrong. Where I live we typically call the interior the warm side. I'd also guess it is about temperature differential. The condensation problem is much worse going from humid 20c into dry -30c.... plus the moisture on the cold side isn't warm enough to dry the insulation and foundation. So vapour barrier goes on the inside with it's most important job being to keep warm interior air from condensing into a cold wall. In the summer, any moisture inside a wall can dry out and escape out the non-barriered wall.

The vapour barrier is behind the interior wall? If so there is some rule of thumb ratio that I can't really remember about adding insulation on the warm side of a vapour barrier. Guessing 1/3rd r value of the insulation on the cold side.(look it up) IMO you don't want anything touching the warm side of the plastic that would trap condensation and grow mold. An air gab between would be a good thing.

This makes sense. But couldn't the same thing be accomplished via signaling sent at a different frequency? I'm assuming both would require a simular control system, but with the controller needing a simple low power transmitter VS the inverters varying the power frequency.

So if I'm reading this right, it is using the grids frequency to communicate/regulate the power sources. I read three lengthy articles on this and all have a very vague explanation of how this is done. It would be really interesting to know the frequency varies based on loads. Anyone know more about this than the OP article?
