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)
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
Problem with boosting voltage because of low light is that there is little to NO power when that happens
Problem with boosting voltage because of low light is that there is little to NO power when that happens
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?
Visit this link here is the clean explanation
http://www.mpptsolar.com/en/solar-panels-in-parallel.html
yes you are right
then difinitley it,s efficiency will be degrade
Nice project! I can't find IR2104 on my market, It can replace with IR2184 or IR2110 (need to modify schematic??)
check out this one in market IRF3205
It mean driver mosfet IR2104, on your project
Nice project!
Can I use another arduino controller like arduino mega2560 instead of arduino Nano?

MY solar pannel is 100Watt rated vtg:-17.5V & rated current :-5.75amp
Hi,
Is it possible to incorporate an external AC charger in case of insufficient sunlight for several days?
plz reply if we use this pannel
yes you can use but would need some modification in source code
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
Nice Idea but you need a Relay to cut off Ac charge when it,s sufficient sunlight and vice versa
Yes indeed..When the panel is producing enough current, AC charger will be disconnect and the solar panel will charge a battery.
just transister place in parrallel no other circutiry changes ?
hi.hope you are well.will you please tell me that is it works with boost convertor?will it be efficient system as in low insolation conditions the voltage may be very low.please guide me about this.
hi. i have project i am working on it. it is only about to get the power from solar and then apply MPPT algorithm using Buck. i just want output source with MPPT without battery charging . Is your code helpful for me or i have to apply new code or my case .
regard
no need a change you can use this code
latest one
Hello wanted to ask what they have for a firmare the ESP8266
LCM1602 is not avalible in market so what we use replace of this one
check this one IRF3205
waqas bhai please app apna question sahi bata dae app ka matlab hai k Market main LCD nai mil rahi am i right ???
IR2104 mosfet driver is not available please suggest another device
Try to fing out 20X4 LCD with module attached you can get this LCD from college road rawalpindi
LCD with module is available at "IC MASTER" shop located at college road go there and buy for your self ………other wise you can change the program and connect lcd without module but i would be a little bit difficult.
I want mosfet driver not mosfet
16×2 lcd is avilible on ic master shop not 20×4

Hi
can I use a fixed inductor that is like resistor in shape instead of the toroid? and what is the effect of doing that?, please
salam.sir we are doing it on atemage8 but we are facing difficulty regarding coding.can u provide it.and secondly we need buck boost or only buck converter.plz explain
NO reply on my comment plz reply.salam.sir we are doing it on atemage8 by using perturb and observe method but we are facing difficulty regarding coding.can u provide it.and secondly we need buck boost or only buck converter.plz explain
i have never used atemage8 if you are using so you must need to update each and every Out/in pins declaration in code …. buck boost is best option otherwise you can use Boost also ..
hi, nice project..
from the schematic the buck converter connector output pin is connected at 5V arduino pin. is suppose to be connected there or Vin arduino pin?
Connect to Vin arduino pin ….You need to do a calibration turn on arduino uno properly using this buck converter ….for this read my article How to Turn on Arduino Using Buck Converter
thanks for the clarification. i notice from picture you posted that there is two(2) extra mosfet is being used..can you show the exact circuit.
hi I have flashed to esp8266 aswell as included the relevant libraries in ardduino IDE but getting this message espcom_open failed
Good day I connected the circuit as on the schematic, but when I add the battery to the project, it keep on burning the 3rd MOSFET the one connected to pin 5 of the mosfet driver. any idea on what might be the cause please.
Thank you.

hi . when i have run this simulation in proteus . the lcd wont display .
same happen with me you resolve it???????? please help me
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
This issue has been resolved By just adding a High ampere Diode at a forward biased direction toward battery input terminal.
Is this project avaialable for sale?? Price tell me…

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
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?
Yes you can use but first, make sure that your solar panel voltage and current is enough to charge your battery
If pv voltage is higher than battery, high-side FET -> Current always flows to the body diode. I think the polarity has changed.
GOOD WORK INDEED. THE CODE IS COMPILING 100% BUT U HAVE TO USE ARDUINO IDE SOFTWARE
Enjoy!
SIR EDIT THE CURRENT READING UP TO 30AMPS AND VOLTAGE UP TO 96V IN UR NEXT UPDATE SIR
You can do some Modification by yourself
* Add More Mosfets in parallel Q1 Q2 Q3
* Increase inductor value
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.

Hello sir,
If I have to write a new code based on my algorithm. Do I Need to make any changes in schematics?
hello, can i have your contact Mr abid
#EZE OLUCHUKWU can you help me
Where Is Schematic Diagram Link
hello sir,what about the algorithm controlling MPPT is P&O ?
Hello sir,
How can I create the library file for the solar panel in Proteus software?
“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.
please how do it get a the circuit diagram used for the above project. thanks
Buy it
where is the aurdino code for this project?
Hi sir i want the same project with a little added feature at the end i.e converting the battery output via inverter and running the load incase if the mains fail .can it be done
