what is Mppt( Maximum power point tracking) ? "we use MPPT algorithm to get the maximum available power from the Photovoltaic module under certain conditions"
How MPPT works ? Why 150W solar solar panel does doe s not equal e qual to 150 w?
For example you bought a new solar panel from the market which puts out 7 am ps. under charge the s etting 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. T hat 66 watts is not going anywhere, anywhere, but it,s due to the poor match of the s olar output output current and battery voltage .
After After using MPPT algorithm we can get the Maxi Maxim mum available power power Battery gets is now 12 amps at 12 volts Output power power is equal to to p= V*I p=12*12=144w Now you still have almost 14 4 watts, and everyone is happy.

Vitor_A 26 October 2015 at 22:28 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 Reply Replies Abid Jama l

yes you are right Reply
boB 3 November 2015 at 19:43 Problem with boosting voltage because of low light is that there is little to NO power when that happens

Brian C 4 November 2015 at 15:33 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? Reply

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 Reply

25 February 2016 at 14:30
Nice Idea but you need a Relay to cut off Ac charge when it,s sufficient sunlight and vice versa
RBT-Techdepot 25 February 2016 at 16:24 Yes indeed..When the panel is producing enough current, AC charger will be disconnect and the solar panel will charge a battery. Reply

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.

7 May 2016 at 05:31
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 ..
Shahreen On 12 May 2016 at 21:08 hi, nice project.. from the s chematic the buck converter connector output pin is connected at 5V arduino pin. is suppose to be connected there or Vin arduino pin? Reply Replies Abid Jama l
13 May 2016 at 16:39
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

Unknown 20 June 2016 at 00:02 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. Reply Replies Abid Jama l

Powering the MOSFET driver IR2104 from battery terminal ( 12V ) instead of solar panel ( earlier ). If anyone making this controller, make this changes and test it. If you have any test results / suggestions, comments it below.
Lukas 23 June 2016 at 09:20 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 t hat? Reply
