    Hello world,

    Is there anybody will help me to find the schematic of MPPT Solar Controller??:)
    I just wanted to know about MPPT solar controller. This is my final task in Polytechnic. Would you like to find me something benefit about solar controller with AVR especially ATmega16, buddy? :)

    Thanks a lot for your contribution, I'll be appreciated it :D

    No, I'm Indonesian people :). This is my final task in Polytechnic. I will make the MPPT solar controller based AVR ATmega16 to control display :D

    would you like to help me finding something useful about MPPT, solar controller tutorial?? :) or something else about solar controller. I'll accept that with pleasure :D

    Thanks a lot

    I don't have the schematic and I use PICs. You could try contacting the manufacturer about a service manual.

    thanks a lot buddy. Is there another one concept about MPPT? :D

    I want to build the MPPT with ATmega controller, maybe my lecturer will help me :)

    Mppt

    The problem is very little people know what MPPT stand for especially the T. Out of all, over 200 documents not one of the authors know that the T is for tracking the sun, in other words a MPPT system is to make the solar panel to track the sun and the only way to do it is by using a Micro Controller, I recommend a PIC MCU.

    If one is busy designing a circuit there can't be a manufacturer nor a service manual.

    If your looking for a design idea, there is a relatively easy way to do it. Place 4 solar cells (circular, cut in 4) at the bottom of a tube and condition the output of each of the cells (I to V) converter. Rectangular cells should work too. When the light is maximized in the tube, each cell will have the same current.

    Now you have to figure out which way to move the motors and you need some algorithm that avoids unnecessary movement due to clouds.

    Only dwarves know what the T stands for?

    Err... no. The tracking in MPPT (maximum power point tracking) refers to tracking the maximum power point of the panel; not the position of the sun. There is a reason so many authors disagree with you.

    There is >1 way.
