So I am kind of lost on what is causing the car reducing the charging amps. I usually arrive home around 5ish in the afternoon to a piping hot Florida Garage. The car starts charging at 40 amps and 248 Volts and once it's ramped up the Service voltage is around 242Volts. The car keeps charging at 40 amps for at least 90 mins and then ramps down to 32 amps. I wonder if my grid tied solar system might also have an effect on this and causes fluctuations in the voltage as it happens around sunset or if the UMC detects the high temperature in the NEMA 14-50 plug. It seems that when I plug in later around 10PM the car never has to reduce the amps.
