I got home from work and plugged in to my HPWC. I normally get 47/48 A 37 mph charge at 12kw an hour. In the middle of the night the wind was owing hard and the lights flickered on and off for about 10 seconds. I went out to the garage to check, and the car had some errors thrown up about closing the port and stepping on the brake. I unplugged, did that, and held in the reset button on the HPWC. plugged in and it started checking, the charging, except now it's at 11kw and 44A. Is this normal for it to reduce for protection and it will increase later or could something be amiss?
