So, "jeopardising" in the seense that, say, me driving west on a road which comes to a north-south "T" in the road, would be "jeopardising" the car's safety...if I don't turn the car in an appropriate manner when I get to the "T". Yes, if you add solar with absolutely no changes elsewhere to accommodate that, you will eventually have problems.
But, that's like saying smartphones jeopardized the cell phone infrastructure, which they did except the cell phone companies added capacity. Bicycles can jeopardize the road network of a city if they become widely used, and you don't do anything (e.g. bike lanes) to accommodate that change. Every change in technology can jeopardize the network it is part of, if nothing else is changed to accommodate it.
But, you know, there are several (already known, developed) methods of handling this (big batteries, utilities being able to turn off your solar like they can currently remotely control my thermostat). It seems a bit of an overstatement to say that it's jeopardizing the grid.
