CR: You start so simply - a solar panel charger but quickly you enter real issues with solutions involving maths, PIDs (yes, I have seen your PID videos) and experimental evaluation. If only your approach and testing philosophy was the standard of You Tube, real progress would be made by many. Your approach seems straightforward; how is its efficiency? Yes, I understand that you are teaching us not building a product to sell. So very well done, CR.

This is by far one of the better videos I've seen. Very well explained and at the same time entertaining too!

I finally succeeded in doing something that I had been struggling with for a while. Sometimes all it takes is finding the right resource or approach that clicks with you.Thank youu for the video

You are an INCREDIBLE and impressive person, my goodness! This has got to be one of the most well-done tutorial videos on any subject that I've ever watched. Everything about it is perfect, I really mean it. Subscribed and really looking forward to diving into some more of your content!

This video is a piece of art!

Brilliant!. All your videos are amazingly well made and super helpful. Your PID video I watched 100 times and used it in a balancing system. I just got a couple solar panels and wondered how to make a charger. Well, after watching this, I am going to buy an off the shelf one. lol. Thanks again. Keep em coming.

First time coming across your channel and all I can say is….. amazing!! Subscribed and looking forward to digging into your other videos! Tried many times unsuccessfully to get a good PID setup on my Arduinos, hoping watching your videos will yield success! My background is in electronics for the Royal Navy and been writing code in one form or another for over 40 years. Keep up the brilliant work!!

Grate video. I could really have used that when I created a project using 12V, 10A peltier elements. I would have loved to control the voltage, in stead I just turned the elements on when the temp was too high and turned them of when the temp was too low. But the peltier elements is more efficient at say 7 and 10V than 12V, thus it would have been much better if I was able to control the voltage. But I found out really quickly that there are some dynamics effects when you turn on and of a 10A "resistor" multiple time a second. I am just glad my power supply survived.

Concise, excellent starting point to go deeper and a soothing voice which encourage learning, very well done! Suggestions for future videos: you made the buck, how about the boost? BLDC control (mentioned elsewhere, I second that), positioning with Kalman filter and IMU, supercapacitor charging control (not far from this video but with different charging approaches)...

Very nice, detailed modular explanation for both hardware and software! I'm subscribing as i'm eager to try that project.

Awesome job of explaining a complex problem in a very simple and understandable way! You have been amazing! Thank you!

Nice film and I love your channel. Please continue to create more films for us. Thank you.

I wish I've found this channel early. Well, now you have +1 sub.

this channel deserves 10M subs

Echoing the opinion of many other commenters, very impressed by the quality of your work! An organic problem solving process that has been well documented and presented with gorgeous and effective graphics, diagrams and footage. Do you do youtube full time by any chance? So much effort must go into these videos.

This panel can put out close to 100 watts ukposts.infoUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.

Super helpful and informative as always, thanks :)

Hello, thank you for the amazing video. It is helping me A TON w/ my senior (bachelor's) project.

This is amazing. Thank you Madam

Excellent video!!! Thank you!

OMG, Thank You very much for this!

Excellent videos. Proper engineering explanation.

You deserve more subscribers

BEST CHANNEL. Thanks so much for your tutorial. Vielen Dank! Gracias!

whoah this video turned out way more technical than expected. I was kind of expecting you to just hijack one of the pins (feedback or on/off) of an existing LM2596 module tho. There's also kind of a bad shortage of low power boost MPPT chargers for smaller projects out there. Errbuddy just wanna do big stuff; the little guys r left fending for themselves.

very nice tutorial, one quick question. can you modify your code to use I2C lcd?

add an emitter resistor for the NPN, thus converting it to voltage controlled current source. Now select pull up to suit the PMOSFET

I agree with Gary. Thank you so so so so much for this video! You have no idea how much you are helping me with a DIY project. May I please ask you, what do you have your current sensor and Arduino connected to in order to get the graphs that you are showing in the video? Like what software or o-scope are you using? I would be forever grateful for your reply. Thank you again for this content.

Very nice videos, what software do you ude to make the electronic Circuit in your videos? Could you make a video on how you create your nice looking videos here on youtube

Incredible video, super helpful explanation. I have one question, Curio Res can you explain how to stop the battery from charging when its fully charged?

Good narrations and video, pls help to increase current to 10A. I have 40V/10A panel

Nice!!! can't wait to try

have you considered having the PID target power vs current?

Can you please...upload a new video in running condition of your project....? Your video is amazing... A few help is needed when the project is under running... So please help us...🙏❤

This is SO well put together, WOwwwwwwwwwwwww.

hi nice video - is there a solar panel, battery with that additional circuit ready to buy somewhere? i want to use it for some project but just want to connect both and not build it myself...

You are genius

Nice and teaching video. What parameters should change to charge 24V battery from 48V panel?

THANKS A LOT CAN YOU PLEASE POST VIDEO FOR THE (CONTROLLING OF DC MOTOR 'ACTUATOR ' PROGRAMABLE POSITION WITH MEMORY BUTTONS USING ARDUINO. BEST WISHES

Excellent video. A bit of an overkill, but depending on your knowledge and project goals you can take the pieces of this content and build it around it. Thanks for sharing.

well done.

I don’t know if you’re a guy or a girl, but you’re great for doing such projects, they definitely deserve a lot of respect for the work you’ve done! Thank you very much for sharing your experience!

Great Video! Can I get the inductor spec? current value, voltage value...?

Really nice walkthrough the entire process. I also liked how you clearly stated what you weren't going to cover. BTW, what software did you use to overlay the graphs on the video?

The buck converter is more than just an LC filter... You need the diode to allow energy stored in the inductor to supply the output, when the mosfet turns off.

Also does the system still work without the arduino mega and temperature sensor?

Which off the shelf ones are as good as yours?

Great voice!

Can I make the same system, but with 12V solar panel? What parts I have to replace ?

Very nice and neat...i tried it before (writing pid with if loops) it kinda oscillated to set value

Hello, um I have a question, what is a good equivalence for the IRF9540 MOSFET if it's not available?

Thank you for this information. Sorry to ask but if the Vin will only be 12V, what good values of pull up resistor and the resistor that would divide the voltage be? thank you

Is it for Li-io)Li-po battery or leadstorage battery?

Hello! Is it possible to list the components used so we can DIY at home please!😊

Can you post a video boost converter

sweety voice ,very good!

Vary nice and vary nice

Is there an MPPT video on the. way? :D

I am very thankful for your amazing explanation. I have a question and I hope you can answer me. If I use 0.5W Solar Panel, 5.5V, 100mA, 55 x 70mm instead of 24v solar panel with circuit you have made. It will work or I need to consider it as a new circuit and i have to change the value of components in the circuit.

Another great video! That was a good example of windup, and easier to understand than in things like motor control applications I've seen. I also appreciate you working through the basics of a buck converter, step by step. Would it make sense to use both proportional and integral terms? Would that reduce the overshoot once the panels resume generating power? I can see that the integral-only controller ramps up more slowly. I imagine that might be better for the battery.

Hi there, I'm looking for this exact build to go with my solar fire alarm project for my bachelor's degree. Can you advise the panel you used for this? I'm finding it hard to source a 24V panel. :)

Is this suitable for lead acid battery?

your videos are beautifully done. what do you use for the animations?

Incredible Video, Very informative, simple breakdown. Are you an electrical engineer? Self taught?

Seems a voltage controllef relay would work just as well On until voltage rises to full charge then shut off. Using the panel voltage to open n/c side of relay. Maybe a Zener diode to control the relay, maybe put a transistor/mosfet between, use a viltage divider with pot to fine adjust the voltage and a small capacitor to slow switch ocillilation delay shut off slightly, then Keep off (transistor on), longer by the stored voltage in cap the battery may drop voltage then the relay will switch panel vack on possibly taking minutes to charge capacitor through a resistor and pot. Adjust to chsrge speed, possibly another to adjust adjust charge current/speed if cap/transistor , much more simple than Arduino, if using a Arduino, why not make a mppt, add a inductor to convert the voltage above full vharge voltage to current, to gsin wattage?

very good video! could someone help me how exactly to get the integral coefficient and what mathematical equations are used

Hii can I get the coding and the flowchart

Also do you have an idea on how i can connect my Mq2 sensor now that the 5V pin is in use! Im a complete novice out of my depth!

Hello, Excellent work! I cannot access circuit diagrams in that link. Could you make them available?

I do not click on notifications as that fast as fast I came here.

Can you do a further video on the PID controller code for this please? I am trying to make one and need to understand the code on it. thanks. Great Vid BTW!!!!!

I was given a solar charge controller project from my college and after working day in day out for days i finally made this solar charge control with the help of your video Thanks a Lot. And the battery is charging. But I have a question does this circuit have autocutt off feature when the battery is fully charged? because by reading the code you have provided I didn't understand that it has a autocutt off feature or not ?

How did you generated the bode plot? Is there any video related to this?

Are you on twitter also?

Thank you for this great video. Can someone help me to underestand how her class file is .hpp type? How I can I create such file to write my code in? Thank you!

woooooow...

please, can u tell me how much watts of the solar panel is?

There is something I cannot understand. I understand that if my input is 12v and the duty cycle is 0.275, the average is 3.3V. However, devices don't work on the average. Even with a smoothing filter, a spike of 12v would destroy most 3.3v devices. So, how does the equipment survive? Does the RC filter smooth the voltage sufficiently for the equipment to survive?

can I have the code sir ? I want to try it

Noob question, is this mopt charge controller?

Hi there do you have an email address. I'm doing something similar to this for college but I cannot get it to work and I'm having major trouble trying to connect the solar panel to the buck converter and the battery to the breadboard! Kind regards Aisling

what is the difference between using a buck converter and BTS 7960 to charge a lead-acid battery? please, reply me as soon as possible, Currently i'm in a project needed this kind of code

Has anyone else got this to work.

Excellent... please upload BLDC motor control ... mainly trapezoidal and FOC ... please please

Useless, not efficient at all.

I have a question: does the inductor need to have a specific ohm or wattage rating?

Thought this was a how to build not here the structure lol

Congrats for your work. Can you share your email ?
