  • ARDUINO MPPT SOLAR CHARGE CONTROLLER (Version-3.0)

    The test code is basically used to see if the arduino is generating the pwm signal at the specified 50Khz There are three duty cycles in the void setup(), once you set it there once there is no need to repeat in the void loop(); just test each of the duty cycles in void setup one at a time by uncommenting only one of the three .you will be able to see perceive the various duty cycles by the brightness of the LED also you can use an oscilloscope to see square the waveforms, proteus(with arduino plu-in) can also give you the waveforms if you simulate.

    Then the pwm signal of the arduino is amplified only in magnitude by your charge pump or oprocoupler cct or whatever your using to at least 10V ;to drive your MOSFET

  • ARDUINO MPPT SOLAR CHARGE CONTROLLER (Version-3.0)

    I made some alterations though ;1.the no IR2104 in my Kenya IR2110 did not work so i used opto coupler PC 8172.Did not use arduino nano ,i used arduino uno to program and made it stand alone and burnt the code into the ATMEGA328P_PU3.Instead of many LEDs i used a RGB led4.Use some features of version4 not yet released .Used DS18B20 temp sensor ;replaced using the serial monitor to input charging set points and temperature compensation with a keypad to make it more practical in stand alone
