    I have the MC240 charger. I use it to charge at either 24 or 30 amps. Will it charge at 12 and 16 amps on 240V or does that only work with 120? Question Two: Is the charging rate the same in standard and range modes? Question three: To get charging miles per hour of charge, I figure 80% of the amps I'm charging at which gives me a pretty accurate number (for 24 and 30 amps), for example; 30 amps X .80 = 24 miles, 24 amps X .80 = 19.2 miles, 16 amps X .80 = 12.8 miles and 12 amps X .80 = 9.6 miles. Assuming I can charge at 12 and 16 amps/240 volts, do the numbers look accurate?

    The charging rate should be the same in standard mode and range mode. Range mode just keeps charging to a higher SOC.

    You can manually set the charging current to a lower number of Amps in the car. The MC240 will limit the max current allowed.

    Hope that helps. Enjoy your Roadster!

    Yes, except that the charging slows as the battery gets full, and it slows even more towards the end of the range charge.
