MPPT chargers are as common as sunshine in the solar charger/controller world.

While MPPT is more efficient, it comes at a higher cost than PWM. In smaller inexpensive systems, PWM charger is a better choice. Also, he mentioned the new "fly-by-wire" steering in newer EV's. While it sounds cool, it's more costly than traditional steering, using dual motors for redundancy and the inevitable lag when turning the wheel. The expression of "reinventing the wheel" is not always better. ;)

Thanks for breaking it down! I have always had a vague idea of what MPPT is, hearing it actually described and explained was very interesting!

Me too. I only had a vague idea. Never new it was so clever..

Was nice video I am working at a solarcompany at the moment and the software team is working on the MPP Tracking at the moment! So was really nice to see how you also shown the difference between PWM and MPP and how they work together!

Really useful and high quality video. In my case, I do not need a fully develop and tested PCB or fancy animations to learn and enjoy the video. However, as an electronics engineer, I never had the chance to learn about MPPT and simple homemade explanations and the project keypoints are enogh. Thank you for all your work. Keep on.

I do like this style of video where you explain the project even before having it completed.

In my experience the INA shunt style sensors work much better than hall effect. I ended up making the switch in my projects after noticing the hall effect sensors after passing current in either direction, still show current after it has completely stopped flowing. This leads to small but inaccurate readings if you are tracking current over long periods of time. Great project. I'm looking forward to seeing the completed version.

I use Hall Effect based sensors professionally. We have to calibrate it when we know the current is 0. This is one of the quirks of using magnetic based sensors. Some applications it’s not possible (have 0A during startup).

@@akhurash These are just my observations, but in the case of a battery monitor, the more current that flows the more the sensor will be offset when the current drops back to zero. I was using a 200A ACS and was noticing plus or minus several hundred mA depending on whether the battery was charging or discharging just before dropping back to zero. Since you work with HE sensors professionally, I'm curious to know how you calibrate for a varying offset. I thought about nulling out the small values, but that would also wipe out the ability to monitor very small loads.

@@ddub9968 Interesting the project we use it on is for a BMS. We do a calibration every key cycle (ignition cycle). The Hall Effect sensor is actually a backup sensor, we use a Shunt as a primary sensor (for the benefits you mentioned).

Here's another comment to feed the algorithm... Nice video! One of my current projects is to have a cheap set of 80V solar panels charge a 12V battery home made out of NiMH cells obtained from an old e-bike battery. All used components are very cheap (

Being off grid we're breaking down Solar instructional as well until growing season ( gardening ). Its awesome sharing knowledge with those that want to learn this beast of a subject matter! When you watching different people doing this everyone picks up a little bit more info as they go along. Best Channel Name! Go Go Electronoobs!

I like the term “exactly 3 hundred and something milliamps “ It made me smile but is also spot on because of the imperfect nature of components

Great video lost my way with electronics for a few years. This video has just got me interested again .thanks mate.

Thank you, I have only touched on MPPT controllers and how they work but now I have a much better understanding of the MPPT method. Keep up the good work.

Very interesting, now I learnt something new. And bonus your video was first in my feed today. I've noticed that if I comment on a video from a channel, even small ones, yt will always recommend me the next video from them regardless of the video performance\views and this is how i trick the algo to keep in touch with channels that otherwise yt doesn't like to recommend. Keep up the great work

Nice video, relaxed style. Looking forward to the circuit and test it out for myself. Don't rush it and stress yourself, we'll be here when it's done...

Very informative. Thank you for the rumbling explanation and yes we will support you more with having conversations here to grow the community

Now this is what i wanted for a long time thanks i hope you'll continue this

I cannot start to explain how useful this explanation video is to me. Thank you very very much

Sir, i had always had a lot of doubts on mppt chargers, your video cleared all my doubts . Thank you sir for this video

You read my mind! I was searching this, but no specific vid like this! Great job!

Awesome video and great production as well. Thanks for your hard work. Subscribed.

I've built your inverter 12V ro 230V and yes, ordered the PCB as well with your design. I see flows :D, but have learnt from it, so Gracias! I'm looking forward to build the MPPT controller next.

Thanks! I find your style of explanation very easy.

I am hooked with your content + quality man, thanks

Thanks dear for best explanation of the circuit❤😊 I'm a regular viewer of your channel and a hobbyist

Thanks! I really like this style of video. Short and more frequent.

Such a great way of answering questions that arise. Great explanations and fulsome information. The graphics are helpful too. One of easier subscription decisions I’ve made…lol…first half of the first video. :)

Nice and comprehensive description! Thank you!

I look forward to your project. I'm not an electrical major, but I really like highly applicable DIY projects like this.

Good explanation of MPP! I am also appreciating your explanations about batteries showing that things are bit more complicated ...

Love the wall art, very original. At least you finish your projects. I'm still perfecting the art of starting new projects in the middle of a previous one.

Love the idea of this project. Looking forward to seeing where it goes. I would be interested to see you post the results either good or bad. I really like the format of this vid too!

Looking forward to this mppt charger. Enjoyed your video , keep on keeping on.

I love your content brother. Very precise and easy to understand.

I was waiting for this! Thanks, friend!

I love the style of the video. For some reason, I loved the video.

Thankyou for putting so much efforts.

I got notified. Glad to be here again. Thanks for the video.

A long awaited tutorial! Thanks !

Haven't watched any of your videos in a while now(haven't been watching any of my favourite channels to be fair). But i have to say this is a great explanation of MPPT. Best iv seen yet.

Thanks for the explanation I've always wondered what the difference was

I like the clear explanation of MPPT that you presented.

Excellent vid, thanks for sharing.

Learned something new about battery charging. Thanks

Great video and good explanations of the MPPT's principle of function

A great video and intetesting project.. looking firward to seeing it progress..

Thank you Great effort All the best for your future endeavors

Great stuff! Need to implement MPPT in a project

I like the torches, lol. That's pretty cool. I see you have them wired up too, very nice.

Thanks for the clear explanation of an MPPT controller.

Moltes gràcies pel vídeo! Agraït de que els tornis a fer i espero que et vagi molt bé el canal!

I like this style video because this format encourages electronic engineering approach to both design and understanding. This creates a forum on a specific engineering topic. I currently am investigating strategies for low power solar systems. (like for a van). This buck boost converter, the LM5118MH/NOPB-ND from Digikey may be useful to squeeze more power from solar panels at lower light levels. Your videos represent a lot of good work! For many of us, even though much effort can be required,............... this is a lot of fun!!

Thank you, I didn't know about MPPT controllers before.

Great video! Keep up the great work. Thanks

Nice video! When I was at university I wanted to do a solar mppt lithium battery charger, but I finally finished uni without doing that.

I'm really looking forward to the new MPPT controller with ESP 32 and graphs etc. Your videos are amazing and I really like you.

thanks for the sharing information that was so simple and clear

alright, alright, a comment for you... seeing your Keysight power supply inspired me to go look up what that cost, to see how it compared to some other options I've been considering lately... well, a lot more expensive, and definitely way out of my current budget. But that inspired me to go refresh some research on other options, which... led me t a purchase of something much less expensive (and, I'm sure, less good in ways) to get me at least started off on having a real bench power supply. So, thanks for that. :D

Hi your project are inspiring a lot of people like me👏👏👍 and somehow got me as an power electronic student I built an isolated mppt charger and it is nightmare. I know that doing project in such verity is hard. Well done.

Thanks for this video. I learned a lot! Best wishes.

Keep going this was very interesting to understand MPPT cheers

thanks for all these information 🎉

Measure current with shunt will limit your maximun power, maybe is better hall sensor, shielded inductors, and software filters.

Very clear and concise explanation

Thank you for all your work

For measuring currents with a very low voltage drop I'd suggest a INA180A2. This is a fixed x50 current sense amplifier. Thus you can use a very low shunt resistor around like 10 or 5mΩ for 10A. There is no fixed module, but you can get them for rather cheap from mouser or digikey.

Love your videos! Keep it up!

i like this format thanks for your time

Keep up the good work bro!

thankyou for the informative video! just to mention something about electric cars that they can use two separate DC systems - one for the motors around 600 - 800 vdc and then one for the instruments etc which as you mentioned is 48vdc or lower. cheers again!

I've learned so much from you.thanks

I can’t wait to be able to get this pcb and code to try for myself!

Very cool, i seen some DIY mppt videos but they made it more complicated that it has to be. Diodesgonewild had a great illustration of it showing a VI curve on an old scope of something unrelated. But it really showed that all MPPT controllers does is what he was doing with the knob dial, adjusting the power, and you could see the curve grow and shrink. Which gave me the idea of manual MPPT controller with just a dial knob, since you dont need it all the time only on cloudy variable weather, it might be good enough to adjust the dial a bit to get maximum power, dont even need an MCU. But mcu would automate all that which is a cool project so im looking forward to the rest.

Those do exist already, they are just a normal DC-DC converter, can be boost, buck, or both, but they have a 3rd adjustment in addition to the usual 1 or 2. The first 2 limit the maximum output voltage and sometimes output current as per normal, but the third limits/sets the minimum input voltage. You just set that 3rd adjustment to slightly below your panel's max power voltage. You set it a little low because the panel voltage drops when the panel temperature goes up so if you set it too high you will form a positive feedback loop of the panel gets hot dropping its max power voltage below the converter's setting so it ends up drawing less power from the panel which gets hotter which drops the voltage more so even less is drawn, Etc. That's the advantage of the tracking, conditions like the panel's temperature are not an issue.

Class video sir. I shall comment. I love your work and your presenting style. Best wishes. :)

Good Video, im also like this side Fakts beyond the project.

I am working on a buck converter and decided to use ina226 at input and output to measure power. My sampling speed for shunt and bus voltage is 256us. So for power, my complete conversion time will be (1/512) us for shunt and bus voltage. Plus I also have moving average filter in a code to filter some noise. Is this sampling speed enough for a buck converter for a stable output current and voltage operation?

Nice video, I learned a lot! Will you do a video on how exactly to make the MPPT? I want to make one that serves as a backup to another battery in my rv. I want it to have two sources: the other battery & solar panel. I’m thinking this would actually be two different mppt, is that the correct approach?

This is flawless man💙😌

Nice video. Can't wait for the main video

Love your info on MPPT. I am looking at 48volt system, not 12v or 24v.

Nice and very informative, thanks.

Very interesting project, will wait on part 2.

Great work. Really like the explanation and if you create a pcb i would love to make my own mpp from it.

Nice one, keep it up!

Great summary, thanks!

It would be also nice to see the design process which you had to go through for the MPPT. Calculations and testing in the upcoming video Great video and explanations.

This is very helpful Thanks

I look forward to the upcoming project.

11:46 I don't know if you know, but lead-acid batteries with 10.5V on their terminals are considered 100% discharged! About 13V = 100% charged, 10.5V = 0% charged. There is no question of using them at a voltage of 7 or 5V because such a voltage means irreversible damage/sulfation of the lead plates from which such a battery is made. This is why almost all converters/inverters cut off the power supply to the receivers when the voltage at its DC/AC input (from the battery side) drops to 10.5V

great video, thank you

Hey Bro,great project. As for the hall sensor, you may put the ferrite coil inside a cage, it may work. magnetic lines are trapped int he steel.

Thank you for this video
