I'm leaving for a 15 day business trip on Sunday morning, and trying to decide if I leave my Model S plugged in or not while I'm gone. I know it should be plugged in ideally, but my concern is we get some decent spring thunderstorms, and god forbid there is a power surge it could hurt the car. I have a PV system with a net meter, and I regularly have fuses that get blown when there are surges. So far nothing has ever been damaged (but I have lots of surge protectors). Thoughts? Am I being paranoid? Of course, my wife will probably plug it in the moment I leave and then move the car seats from her car, making this all moot.
