Home Made Maximum Power Point Tracking (MPPT) Charge Controller | Updated 2020

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

Abstract

For maximizing a photovoltaic (PV) power, continuously tracking the maximum power point (MPP) of the system is highly required. MPP of the PV system depends on solar radiation conditions, ambient temperature, and the load demand. Maximum power point tracking (MPPT) techniques can catch MPP of PV system. Such techniques can be realized in many various forms of hardware and software. The goal of this project was to develop, construct, and test a working solution to the MPP problem with a limited budget. This tutorial Contains the general circuit of MPPT, the panel cell and it is a formula, about how MPPT works, the required parts and sub-circuit. we choose buck converter in our project and explained how to use Arduino and how to apply it in Proteus.

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 CHINA because it is the Main contributor by producing 63% Co2 | Alternative energy.

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.

Model of Arduino Based MPPT Algorithm Charge Controller | Alternative energy

 

Project Flow Chart : 

Starts reading its analog inputs:

  • The voltage supplied by the PV panel
  • The current drawn by the PV panel
  • The voltage of the battery

Once all inputs are read, it calculates the current power supplied by the PV panel by multiplying read voltage by reading current.

Then the charging configuration is set according to the above readings:

  • If the supplied PV power is very low (night time, cloudy weather, dirty panels) the charging state is set to OFF, The MOSFET driver is shut down, and the PWM rate is set to 0%
  • If the supplied PV power is low and the battery is not fully charged, the charging state is set to ON, the MOSFET driver is enabled, and the PWM rate is set to 100%.
  • If the supplied PV power is medium to high, and the battery level is not fully charged, the charging state is set to Bulk, the MOSFET driver is enabled, and the PWM rate is set to 100%.
  • If the supplied PV power is medium to high, and the battery level is fully charged, the charging state is set to Float, the MOSFET driver is enabled, and the PWM rate is set to Maximum.

The next task is the settings of the output load control:

  • If it is night time and the battery voltage level is higher than the “Low Voltage Disconnect” threshold which is 11.9V, the output is enabled and the battery supplies its energy to the load.
  • If it is day time and the battery voltage level is higher than the “Low Voltage Disconnect” threshold which is 11.9V, the output is also enabled, but this time the load is energized by the battery and by the excess energy supplied by the PV Panel
  • If the battery voltage level gets below the “Low Voltage Disconnect” threshold which is 11.9V, the output gets disabled and the load gets disconnected.

The next step is to set the Battery voltage indicators by turning on the corresponding LED:

  • If the battery voltage level is lower than 11.9V, then the RED Led is turned on.
  • If the battery voltage level is higher than 11.9V but lower than 14.1V, then the GREEN Led is turned on.
  • If the battery voltage level is higher than 14.1V, then the YELLOW Led is turned on.

Next, the Arduino updates the information displayed on the LCD screen according to the above processes and then starts another reading of the inputs to start the loop phase process once again, and then it continuously repeats this loop over and over. 

Project Simulation in Proteus by Using Arduino Nano ( UPDATED 2019)

This Simulation has been designed in Proteus Software 8.6 version. You can make your own by using Arduino Library for Proteus and a simulation tool known as Proteus. 
Project Schematic Diagram Explanation

Section A: is the input of the system which is the power supplied by the solar panel. The fuse F1 and TVSs represent the protection network against any high current that could happen to the circuit. The Voltage divider network (R1, and R2) are used to scale down the voltage provided by the solar panel  (VPV) so that the maximum voltage supplied to the Arduino analog input (A0) doesn’t exceed it the maximum voltage limit which is 5V. The output voltage of the voltage divides is one-sixth (16) of the input voltage. So the maximum value for the PV panel voltage should not exceed 30V.

VA0= R2R1+R2 VPV= 20100+20 VPV= 20120 VPV= 16 VPV

Section B: is the current sensing network for the power supplied by the PV panel. The ACS712-5 is a hall-effect current sensor chip whose output is an analog signal proportional to the current passing through the chip. The capacitor is a general filter capacitor. The output of the current sensor is connected to the second analog pin of the Arduino (A1).

Section C: represent a blocking circuit that allows the current to flow in only one direction which is from the PV panel to the charging circuit. The aim of this circuit is to protect the PV panel from the battery voltage when the solar panel is not producing electricity. The MOSFET transistor Q1 gate pin is connected to the MOSFET driver chip (IR2104) through the diode D3. So that Q1 is engaged only when the MOSFET transistors are operational.

Section D: is the charging network. The MOSFET driver chip will control the MOSFET pair Q2 and Q3 in a push-pull configuration to enable the current to flow inside the coil. The output of this network is connected to the battery to be charged.

Section E: is another voltage divider connected to the third analog pin (A2) of the Arduino. This network feed the voltage of the battery into the Arduino to measure it.

VA2= R8R7+R8 Vbat= 20100+20 Vbat= 20120 Vbat= 16 Vbat

Section F: is the output load control circuit. The Arduino output pin (D6) control the base of the NPN transistor Q5, which in turns control the gate of the MOSFET transistor Q4

responsible for allowing/ block the current to flow from the battery to the load. Whenever D6 is low (0V), the base of Q5 will be high, and the MOSFET Q4 will be passing the current. When D6 switch its state to High, (5V), the base of Q5 will be High, and the MOSFET Q4 will be open circuit and the current flow will be blocked.

Section G: is the Push-Pull MOSFET network driver. It drives the MOSFET transistors Q2 and Q3 based on the signals generated by the Arduino board at pins D8 and D9.

Section H: is the voltage regulator circuit responsible of supplying the Arduino with the rated voltage (5V). The input to the regulator is the battery. The output of the regulator are mainly the Arduino board and the LCD display.

Section I: is the serial LCD display. It uses the I2C protocol to communicate with the Arduino Board.

Section J: is the visual indication LED used to state the voltage level of the battery. The resistors R11, R12, R13 are current limiting resistors used to prevent the voltage supplied by the Arduino (5V) from damaging the LED which requires only 2 volts to operate.

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

Regards

boB November 4, 2015 - 3:43 am

Problem with boosting voltage because of low light is that there is little to NO power when that happens

Brian C November 4, 2015 - 11:33 pm

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.

Thoughts?

waqas sahi February 25, 2016 - 10:24 pm

plz reply if we use this pannel

Abid Jamal February 25, 2016 - 10:27 pm

yes you can use but would need some modification in source code

Abid Jamal February 25, 2016 - 10:29 pm

Maximum is 50 to 60 watt for higher watts you need to modify the circuitry by just placing more transistor in parallel …dont forget the heat sink,…enjoy

Abid Jamal February 25, 2016 - 10:30 pm

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

RBT-Techdepot February 27, 2016 - 3:06 pm

Yes indeed..When the panel is producing enough current, AC charger will be disconnect and the solar panel will charge a battery.

MD Mini 3A Dc Step-Down Power Supply Module LM2596 (Green circuit)
Also, I found a similar circuit on this website
http://www.instructables.com/id/ARDUINO-SOLAR-CHARGE-CONTROLLER-Version-30/
Can you tell me the difference between the circuit and your circuit ? As both circuits have some similarity and I am a bit lost.
Also some of the pictures are not clear enough, what are you using three push switches for?

ali fattah November 1, 2017 - 10:55 pm

hi thanks for your attempts to build a such an amazing design.i have a question.there is a similar project in instrucable site that the developer mentioned the problem that Q3 mosfet got so hot and suddenly burned.did you had the same issue in your schematic?and also i need a simulation flie of your project can you help me with that?thanks a lot and god bless you.

Abid Jamal January 11, 2019 - 2:29 am

We have Resolved that issue by Adding more MOSFETs in parallel along with adding high ampere Diode to Q3

Abid Jamal November 15, 2017 - 10:58 am

its optional, No need to change.

Abid Jamal November 15, 2017 - 11:09 am

Hello,

Did You compile the code ?

Is it error free ?

Have you download Schematic PDF correctly ?

Connection Diagram is given clearly in Schematic

Yes i have used 6 Mosfet for better results + good efficiency.

I have designed this circuit but it did not work. I need to know how to connect the buck IN+, IN-, OUT +, OUT- in your circuit. Also, I see in the pictures that you are using 6 MOSFETS but the design have only 4 MOSFETS. Can you please supply my with the final design. If you help me to make this work, I will donate to you. Thanks. 🙂

how did you get the solar panel in proteus for your simmulation

Abid Jamal December 3, 2017 - 6:06 pm

This Solar Panel Module has been designed manually

Abid Jamal December 3, 2017 - 6:44 pm

I placed Two extra Mosfet Transistors in Parallel with other ones, YOu need to use more Transistors in Parallel with Big size heat sink for higher capacity.

Anonymous December 3, 2017 - 6:06 pm

Hello,
Can you please clarify if this circuit can work for a 400 watt solar panel or not?
Also can you please tell where did you place the two extra mosfets?
I will donate if you help me.

Nikhil Chakravarthy Chukka December 7, 2017 - 5:36 pm

Do we need to change the code if we use 20watt solar panel and could you please send me the circuit diagram.

Abid Jamal December 7, 2017 - 5:40 pm

No you don't need to change the code, Click on "DOWNLOAD Schematic Diagram" kindly read article carefully.

Nikhil Chakravarthy Chukka December 13, 2017 - 9:42 am

In instructables Deba168 said that mosfet is burning how to solve this problem sir?

Nikhil Chakravarthy Chukka December 13, 2017 - 9:42 am

Here you have used 2 extra MOSFETS could how to tell the exact position of their connection.

Abid Jamal December 13, 2017 - 9:58 am

Just like the others, simply put 2 extra mosfets in parallel with others…

Hi there great project you have there,

Just wondering if I already have a built up working buck boost converter.
How should I go about integrating this project with buck boost converter?

Regards
John

tzitzu February 3, 2018 - 11:40 pm

hello,
Is there any chance to improve the load and the charging current?
irfz44 goes up to 50 amps properly cooled, also acs712 there’s a 30 A version.
a mppt with 25A charge would be great

Abid Jamal February 6, 2018 - 2:52 pm

You can Improve its performance by adding more irfz44 in parallel with other ones.

The sourde code is compiling perfectly well. What i did in my own case was that i download an earlier version of the arduino IDE i.e version 1.6.1. And thats it. try and see.

Manuel March 20, 2018 - 3:27 am

¿ Would it work using a 10 W solar panel ?

Abid Jamal March 20, 2018 - 3:35 am

yes

Manuel March 20, 2018 - 3:57 am

My panel’s characteristics are these:
1.Rated Voltage= 12V
2.Maximum input current = 0.55A
3.Load current support up to =not sure, I suppose 1A
4. Input Voltage = Solar panel 18 V
5.power of Solar panel = 10 Watts

¿ What changes do you think I need to do it in your schematic to get the proyect running ?
Thank you in advance

Abid Jamal March 20, 2018 - 11:29 am

No need to do Changes ✅

Manuel March 20, 2018 - 11:55 am

Hello, I am looking to use a 2s LiFePo4 battery to charge each cell to 6.25 volts. The nominal voltage is 3.3 v/cell. Our solar array consists of 15 SunPower Maxeon solar cells, producing 8.175 v and 6 A at full sun. What changes will we need to make the MPPT charge controller and its code? Thank you.

nick April 2, 2018 - 10:40 pm

would it work using a 6.25 volt battery?

nick April 2, 2018 - 10:41 pm

would it work using a 6.25-volt battery? with 15 cells charging it

haffizi April 19, 2018 - 9:08 pm

hi Sir, can this simulation(proteus) get the charging algorithm. If can, how to get data analysis from charging algorithm.

Egon April 23, 2018 - 7:14 pm

Will this work with a bench top power supply as input in stead of a solar panel?

Egon April 23, 2018 - 8:04 pm

JOAQUIN SANCHIZ May 10, 2018 - 2:28 am

Hi Abid
thank you for sharing your project
I have a couple of questions. Probably I do not fully understand the schematic but I find two issues. Can you help me?
IRFZ44N are N channel Mosfets and Q1 and Q2 are in the high side of the circuit with the source in the positive pole. Aren’t they always on?
is this what you want? isn’t it better in this situation a P channel Mosfet?
and, when Q3 is on, doesn’t it shortcut the positive pole of the battery to ground?
thanks in advance
Joaquín

Abid Jamal January 21, 2019 - 2:30 am

This issue has been resolved By just adding a High ampere Diode at a forward biased direction toward battery input terminal.

hello sir i am doing project it is like battery should be charged from and solar panel and in night automatically load should get ON and whenever the solar is not charged due to climate problem or rainy season that time it should get charged by an home supply automaticaly . if you help me it will be very help full .

Thank you

Umai Ahmed November 6, 2018 - 6:05 pm

Sir, Iam making the similar project but using the 3watt solar panel inplace of 50watt due to cost of solar panel , can i use the same circuit for 3watt solar panel and my battery is of 12volts?

Abid Jamal January 21, 2019 - 2:33 am

Yes you can use but first, make sure that your solar panel voltage and current is enough to charge your battery

UNKNOWN December 22, 2018 - 9:09 am

If pv voltage is higher than battery, high-side FET -> Current always flows to the body diode. I think the polarity has changed.

EZE OLUCHUKWU January 20, 2019 - 11:40 am

GOOD WORK INDEED. THE CODE IS COMPILING 100% BUT U HAVE TO USE ARDUINO IDE SOFTWARE

You can do some Modification by yourself
* Add More Mosfets in parallel Q1 Q2 Q3
* Increase inductor value

Anupam Dasgupta January 22, 2019 - 8:16 pm

Hi, I am Anupam, it is a very interesting project and I would love to construct it because at present I am charging my inverter battery directly from PV panel. Would please kindly give me the code. Further the details of construction of the Inductor is not there which is also required.

Naha Arjun N September 15, 2019 - 3:50 pm

Hello sir,
How can I create the library file for the solar panel in Proteus software?

Freja Meincke January 19, 2020 - 8:15 pm

“we use MPPT algorithm to get the maximum available power from the Photovoltaic module under certain conditions” For example, you bought a new solar panel from the market which puts out 7 amps. under charge the setting of a battery is configured to 12 volts: 7 amps times 12 volts = (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.

Jerry Ikenna March 15, 2020 - 12:20 pm

please how do it get a the circuit diagram used for the above project. thanks

Abid Jamal March 16, 2020 - 10:00 am
