For some reason the SOC calibration isn't what it should be.
I've seen a video on YouTube to adjust settings for solar charging charged voltage 0.3v under absorption voltage in normal operation it should be under float voltage
But when my 75 15 mppt is in end of absorption it resets it's state of charge.
Mppt keeps charging for a few more hours with 4 amps that means the reading is not close to accurate.
BMV and Smart Solar both Bluetooth connected also with a battery smart, if the mppt and the BMW could talk it could reset it's state of charge when it hits float charge.
Any settings to change to get it as close as accurate?
