    Has anyone checked the reported charging voltage with a calibrated instrument? It seems to be reading quite high, over 1% error for me. I don't have a single calibrated meter but I do have many of them which all read lower.

    My car generally reads 1V higher than my actual voltage.

    The last 5 days or so, I've been suffering from high voltage after a few storms. My solar inverters are reporting 255V, the signature Model S shows 256V, and the Model X was showing 256-257V.
