Vacations Parked

I am leaving the car in the garage for 3 weeks - I am leaving it plugged to wall charger (220v), at 75 % battery limit (to assure car has charge even if electricity stops) and at 30 A max (to have charge less aggressive when needed) - Thoughts ?

I would like to know pro's and con's too. I just left mine in garage for 2 weeks while out of country on 110 power with sentry mode on. keeping the charge at 80% so basically it charges in early morning the 10 miles it burns on sentry mode per day. I don't know the difference in cost (and don't care) between 110 and 220 but in my mind a slower charge rate might be safer if nobody home. who knows.

I left on 11/18 with ~ a 240 mile charge on my S - I left it unplugged. When I returned home on 12/12 I had ~ 170 miles remaining. I do have sentry mode off when it's at home in the garage. I've plugged it in on similar trips in the past and it will top up the charge once in a while - you'll be fine either way if sentry mode, preconditioning, overheat protection, etc is turned off.

Thoughts ?

Plug it in and leave, the car will take care of itself.

My question is more about 30 A as the correct option

It matters not one bit. Sure, choose 30. Or 40. Or 20. Heck, maybe 17 if you’re feeling frisky.

Generally I think a few amps below the maximum supported for the charging type is always a good idea, whether you need the vehicle the next day or more than a week later (e.g. for 14-50 a good value might be 35 A, or for 6-20 it might be 14 A). This will help to generate less heat and strain on the system.
