I'm not 100% sure, but I think i read it was mandatory/required by law to connect your inverter to the internet in The Netherlands, because they need to be able to "turn off" the inverter in case of emergencies when the power grid becomes overloaded. The part i'm not sure about, is whether this system depends on the internet connection, or whether there's some other wireless system build into these things.
