> but otoh you could likely drive a big truck into the right power poles and cause a similar sized outage

I get your comparison and the following is probably obvious to most people, but I feel like it really needs to be said: this requires being there, having a truck and the willingness to risk almost certain jail time, whereas taking down all SolarEdge installations on the planet could probably be done by an anonymous teenager in a foreign country with nothing but a computer and TOR client.

(I mention SolarEdge because I just had to deal with one of their systems and it pissed me off, I don't actually know of any vulns)
