Huh, weird. I’d have expected any signalling like that to come through the power lines that the solar system is connecting to. Using an internet connection for it seems like adding unnecessary complexity, procedural fragility, and another point of failure—and it’s not like your internet connection is more reliable than your power supply, most have no effective battery backup and go down immediately if they lose power. And not everyone even has a persistent internet connection—living out in rural western Victoria, I use a cell phone for my internet supply (it’s the best non-business service I’ve experienced, actually, though NBN fibre should be better now: clear line of sight to an Optus tower 400m away that serves under a hundred people; the only alternative is satellite—under half the speed, over twice the price, and 600ms latency). (Mind you, I would still expect this to be completely distinct from anything about voiding a manufacturer’s warranty even if it was a grid-connected system which is probably but not necessarily the case.)
