MPPT CHARGE CONTROLLER

Dear all,
Here we are with Arduino based MPPT charge controller.This project is inspired from Mr. Tim Nolan’s Arduino MPPT. We can share this as long as we mention his website link.
Here is the link:  Click here

The display part is taken from the KIBI: Click here
We didn’t use Tim Nolan’s hardware as we wanted to be different and simple (No MAX IC’s).
Our circuit diagram is given below:


We tried to make the circuit using IRF5210 because of high input capacitance we shifted to IRF9540. We used instrumentation amplifier TL082 to amplify the solar current. To generate –ve voltage required for TL082 we used 555timer and lm7905 for -5volts generation Modification in the software:
We modified the code so that PWM is around 20 KHz and our MOSFET’s are happy at this lower speed.


For your reference this is the link for Mr. Tim Nolan’s circuit:

    Hi, I like the idea of doing the Tim Nolan simple design with easier to get IC's. Is it really necessary to use the TL082 or can I use a different opamp with single supply (358 or 741) and forget the NE555? And what shunt do you use? Greetings, DJ

    Your project is amazing, i really feel good when i see stuff related to renewable energy. I have Designed my own Mppt by using Arduino nano with given Electrical specifications:

    1.Rated Voltage= 12V

    2.Maximum input current = 5A

    3.Load current support up to =10A

    4. Input Voltage = Solar panel 12 to 24V

    5.power of Solar panel = 50 Watts

    Such good Information provided by you about MPPT solar charge controller. MPPT or Maximum Power Point Tracking is an algorithm that includes charge controllers used for extracting maximum available power from a PV module under certain conditions. Enertech also provides smart MPPT charge controller with 30 amps, 12-24V - loom solar save 10% of energy.
