HPWC installed and tested, charging rate is 56/56A 34mi/hr, is this normal?

    Put 100 A breakers and rotary switch positioned D(80A~100A).


    Any advice is welcomed with thanks~

    Did you cycle the power and breaker after setting the rotary switch?

    That's a very strange number. An X without the fast upgrade is limited to 48A, while one with the upgrade is 72A, and the charger should be telling the car 80A.

    What's the voltage showing? Maybe the drop was large enough the car dropped the current draw back in response?

    Try increasing the current on the center screen. You also might want to watching it start to charge to see what the voltage drop is.

    Thanks for time posting an opinion.
    Cycle means Shut the breakers and reconnect?

    Yes, you need to record voltages also as it begins charge and after it ramps up as OP noted. Something odd.

    56/56 means your WC is configured to output 56A. Check the DIP switches inside the WC to make sure it is set to 72A or 80A.

    It is reading as 204 v.

    Switched to D as 80a - 100a.

    204V from a domestic 240V split phase would be serious cause for concern. 242V like your image says isn't - unless your service normally runs very high, there shouldn't be enough drop at that point to get current limiting.

    Thanks,

    The problem is now resolved.

    Reset the breaker as advised and it works great as the attched photo.

    Thanks a lot.
