Home Made Maximum Power Point Tracking (MPPT) Charge Controller | Alternative energy

Arduino Based MPPT Charge Controller | Alternative energy |renewable energy sources | clean energy


What is Mppt ( Maximum power point tracking)?
We use MPPT algorithm to Extract the maximum available power from the Photovoltaic module under certain conditions. MPPT is a Most Popular tool that helps us to use Solar Energy (Renewable Energy Source) in an efficient way. If we want to Reduce the Graph of Carbon footprints then we must need to move towards clean Energy which is called Renewable Energy ( Energy we can get from Natural resources) Like SOLAR, HYDRO, WIND e.t.c otherwise we will directly move toward Global Warming.
Every Country needs to Move towards the Green Energy especially the CHINA because it is the Main contributor by producing 63% Co2.

How MPPT works? Why 150W solar panel does not equal to 150 w?
For example, you bought a new solar panel from the market which can deliver 7 amps current, under charge the setting of a battery is configured to 12 volts: 7 amps times 12 volts = 84w (P=V*I) You lost over 66 watts - but you paid for 150 watts. That 66 watt is not going anywhere, but it,s due to the poor match of the solar output current and battery voltage.

After using MPPT algorithm we can get the Maximum available power Battery gets is now 12 amps at 12 volts Output power is equal to p= V*I p=12*12=144w Now you still have almost 144 watts, and everyone is happy.

  1. Hi, nice project. There are some solar converters that are buck boost . The boost will increase PV low voltage under low luminosity condition. For example if the solar panel is generating 5V, it could be boosted and deliver some battery charging current

  4. What would be the pitfalls of trying to run multiples of these in parallel. I'm thinking a system with multiple panels/controllers charging a single battery bank. Much like a system with multiple panels and multiple inverters (like the enphase micro-inverter) running in parallel.

    1. Nice Idea but you need a Relay to cut off Ac charge when it,s sufficient sunlight and vice versa

    2. Hello,
      tried that solution, pin 5 MOSFET is getting rly hot over here too.
      But only on low PWM-states like 40% and less.
      The ir2104 timing diagramm shows that on lower pwm-states its mostly on (IN=0).
      When IN = 0, LO = VS => Q3-Gate-Source = 12V.
      That means it shorts Bat + to - via the inductor.
      Am I right with that?

  37. Hello,

    Nice project. Very similar to: http://www.instructables.com/id/ARDUINO-SOLAR-CHARGE-CONTROLLER-Version-30/

    His is based on the timnolan tracker: http://web.archive.org/web/20130430163911/http://www.timnolan.com/index.php?page=arduino-ppt-solar-charger

    but the problem with the instructables article that as he said, it is NOT working.

    I want to do a hybrid grid standby installation where if there is enough juice in the batteries the loads are operated from them but if the batt voltage falls below a critical level (night or cloudy) then an AC transformer would kick in to charge the batteries and also power the load right away in an uninterruptable fashion.

    For just switching seamlessly between the grid voltage and battery I could use PicoUPS which can handle load up to 10A.

    Can you please confirm that your design is fully working, it does not overcharge or damage the battery or other problems? If so I will base my design on yours.

    Thank you!
