  • A Wind Turbine MPPT Regulator with an Arduino Uno 3 months ago

    Hi, the very first time the EEPROM values are set to 255. 131, 51 and 41 are not significant values. It must be something that show that stored values are wrong for the project.
    EEPROM of the ATMega329p can only store unsigned 8 bits values, so from 0 to 255.

  • A Wind Turbine MPPT Regulator with an Arduino Uno 3 months ago

    Hi Philipp, thank you for your feedback, and sorry for late reply, I do not understand why I do not always receive a notification in case of new message.
    Here are my answers:
    1- no problem in fact.
    2- the turbine voltage will NEVER be over the battery voltage. A full charged 24V battery reach 32V. So the turbine higher voltage will be 32V. But you have to understand that if your turbine can get 60V with no current, with a current to voltage will be much lower, for 2 reasons: the ohmic law U=RI with R=L*2pi*freq, and the electomechanical law: as soon as there is a current, the turbine will decrease its speed.
    So there is no problem. With high wind the voltage will reach the battery voltage and will allow a high current: everything is perfect until the battery is charged. The battery charger manuals say that a battery is charged after 12 hours of a Vmax charging voltage, eg 32V for a 24V battery. The charger manuals also say about a Imax current of charge. So if it is very windy and sunny, you will have to take care of point 1...
    3- no problem in fact
