Fantastic Explanation, Others are emphasizing on the useless parts, Your video covered in explaining the foundations of MPPT in the easiest possible way available on the internet
Hi Sir , my name is Majid , I live in Iraq, the area of the most power crises , I bought an mppt type Ipanda 30A a year ago , I used 3 solar panels of 36v , Isc is 5A in series , it wotks well , untill I bought a 4th one with same rating , on sunny days it gives me a full power by connecting them series-parallel , in order not to exceed ths max mppt pv voltage which is 150V , untill I noticed that at cloudy sky or in the morning , my mppt stuck at low voltage , and never goes up unless I disconnect the pv wire snd connect it again so full power goes out , is there any thing I can do ? Please cpnsider my video below which shows the problem .. thank you sir
I'm a big fan of MPPC. The disadvantages seem to be outweighed by the numerous MPPT controllers that easily get lost in tracking with long strings. Bypass diodes are about every 10V and a momentary partial shading can cause locking onto that lower "power point" voltage. I have controls that monitor panel voltage and reset controllers to a higher power power point with significantly higher wattage produced. Example, a 60V string will lock into 18V. A momentary disconnect will restore controller to the 60V region with higher power output. In short there is often a high cost to MPPT tracking too.
sir your explanation is simply awesome,except at one portion while explaining the flow chart of incremental conductance method, you said "left of mpp" instead of "right of mpp" however I finally arrived at the right video
Great video to explain MPPT methods. As you noted there are other methods ---9yrs later it would be interesting to hear what some of the other techniques or methods are ----> Please do a follow-up video. Also it would help if you could clarify why and by how much Imp > Isc.
Mppt works as long as you have somewhere to dump all the power generated, works great with grid tied systems or systems with oversized batteries, not so great with off-grid or lead-acid battery based systems. also mppt works the best for single panels(micro inverters), for a big array several local maximum power points might exist, but there is only one global mpp. Last two(direct) algorithms seemed to be the same to me - adjust voltage and check the impact on the power. Also i think the algorithm should start from open circuit voltage and zero current and start increase the current and not from max current and start increase the voltage( like in the animations). Also microcontrollers these days can work preaty fast(stm32f1 series up to 72MHz with hardware PWM plus you can configure ADC to scan all the channels using DMA for these applications it is almost real time operation for this kind of task if you stay clear of arduino and python, and that's not the top end like F4 or F7 series MCUs of ST, i know there are better ones, its just the ones i had my hands on). But hey, what does a random person on the internet from the future know.
can we connect two mppt solar charger controllers to the same solar array ? This is because i have one mppt that works on grid when i have the grid power and then I have another mppt which charges my battery with solar array when there is no grid .
Very helpful thank you. Im looking for a simpler solution. Say a potentiometer thats lets you set the voltage while watching power either go up or down. You being the tracker. Gets rid of all that overhead and complexitity and coud be worth in some cases where you dont need constant and percise tracking. I have a similar situation with solar tracking as the day goes along. I only need 3 positions, not constant perfect tracking so Im hopig to get an understanding of mppt charge controllers to achieve something like this. Seems like all you'd need is just away to limit the voltage/current, but also not waste it as heat and you should be good for setting up maximum juice for your system. An automated circuit would be ideal, but for educations sake i think a simpler circuit showing the essence of the mppt idea by doing it manualy would be helpful.
hello!!!! can you provide me a video talking about synchronization of two microsources in matlab /simulink by controlling frequency and voltage by using DROOP CONTROLLER
Boost converter diode was drawn in wrong direction! "Implementation of incremental conductance method not easy." Why not? An MCU can calculate G=I/V and dI/dV as well as it can calculate P=I*V, and dP and dV.
MPPT is not unique to PV cells/arrays, it applies equally to hydro generation and wind generation although, in the latter case, the response time may need to be shorter/quicker.
P = VI if you take the derivative of power P with respect to voltage V you get, dP/dV = I + V(dI/dV) [use product rule to get the derivative] Now at maximum power point (MPP) dP/dV = 0 (it's a stationary point) Then make dI/dV the subject of the formula above and you get dI/dV = -I/V hope this helps
It's not unique to PV. Any energy source has a trade off situation that results in an optimum compromise that varies depending on source and load conditions. Consider bicycle gears... These are selected to optimise the trade off between torque and revs so that the cyclist can produce the most power in the specific riding conditions and his dynamic strength.
so basically if i want to implement a basic MPPT controller to a project, I just need to put a buck boost converter to my system, measure the V open circuit to multiply it by the constant, and set this value on my voltage output on the converter.
No matter how profound the content I refuse to watch a 20 min video with 10 ads. And I'll give thumbs down as well without watching. So keep that in mind with your next vid please
CZcams is a free platform and these people are giving you University level instruction for free. And you're going to complain that they're trying to make a penny off of it. 😒
Half panel shading and diode bypass?? In a string this is essential as the shared series resistance will cut total string power. The input voltage must get drawn down until the bypass diodes turn on. Even a weak shading will generate enough voltage to reverse bias the bypass diode. You missed the whole point. Your schematic is not a buck boost it's buck only. You need more training especially for a university. Wow. You don't know how panels are built and configured?
One of the best explanations of MPPTs on the interweb.
yeah - finally found one that gives me the info I was looking for. Great Video.

2019 Uber explanation, I wish my university teachers were as good!
really gud presentation
Good explanation
good job done
Thank you
sir,
your lecture is simply superb with the clarity explanations and pronounsations.thank you sir..
4:40 Sir, how can the irradiance change the I-V and P-V curves? Isn't irradiance an extrinsic property?
excellent....
very nice lecture

But hey, what does a random person on the internet from the future know.
I like your flow, future man.
Was thinking the same.
"Wont using any shitty none mppt solution work as long as im nowhere near the peak panel output?"
thanks :)
can we connect two mppt solar charger controllers to the same solar array ?
This is because i have one mppt that works on grid when i have the grid power and then I have another mppt which charges my battery with solar array when there is no grid .
Thanks :)
hey! could you help me with building a MPPT? i'm a dutch student on the Hanze Hogeschool Groningen. i love the innovation!
thank you sir ......
how does mppt increase current to the battery ??
@17:35, he makes a small mistake, says 'left' instead of 'right'.
why solar charger controller use with pv-panel if by-pass diode are used with pv -panel
Very helpful thank you. Im looking for a simpler solution. Say a potentiometer thats lets you set the voltage while watching power either go up or down. You being the tracker.

What's the k constant, exactly?
hello!!!! can you provide me a video talking about synchronization of two microsources in matlab /simulink by controlling frequency and voltage by using DROOP CONTROLLER
VERY COMPREHENSIVE. THANK YOU!
Thank you a lot but i have a question about icremental conductance algorithme : What if we had DV=Vt-Vt-1 =0 what should we do ?
We control dV. If 0, means control loop is dead or stuck.
Boost converter diode was drawn in wrong direction! "Implementation of incremental conductance method not easy." Why not? An MCU can calculate G=I/V and dI/dV as well as it can calculate P=I*V, and dP and dV.

MPPT is not unique to PV cells/arrays, it applies equally to hydro generation and wind generation although, in the latter case, the response time may need to be shorter/quicker.
ΔI/ΔV = −I/V, at MPP why is the R.H.S negative. Please clarify
For delta V as positive (moving towards right), delta I is negative at MPP.
P = VI if you take the derivative of power P with respect to voltage V you get,
dP/dV = I + V(dI/dV) [use product rule to get the derivative]
Now at maximum power point (MPP) dP/dV = 0 (it's a stationary point)
Then make dI/dV the subject of the formula above and you get dI/dV = -I/V
hope this helps
Thanks Lucifer for explaining this to me
Some people can be so heartless, don't you think?
12.45 struggle of mppt is wind turbine I'm i right
There is still space for more ads. I could still follow you, that means you missed the point of showing us a mass of ads!
Wel goed uitgelegd maar alleen hij moet nog even werken aan de Engelse taal :)
Excellent explanation on MPPT. Just the Ads OMG, its just so annoying.
Can you provide me mppt technology
Good video but too many ads
It's not unique to PV.
Any energy source has a trade off situation that results in an optimum compromise that varies depending on source and load conditions.
Consider bicycle gears...
These are selected to optimise the trade off between torque and revs so that the cyclist can produce the most power in the specific riding conditions and his dynamic strength.
I don't know what are you talking about?
Why cant good quality and funded videos like these be made for our niche subjects. Like wtf, I'm paying thousands of dollars anyways.
so basically if i want to implement a basic MPPT controller to a project, I just need to put a buck boost converter to my system, measure the V open circuit to multiply it by the constant, and set this value on my voltage output on the converter.
I made it by myself. I used inplix scripts for that.
I’m confused because he sounds like an Indian man but looks anything but Indian.
some thing wrong with this guy 🤔🤔
he is reading his text from a sheet and he is pronouncing it in dutch but at least he gets his points across...how is your dutch?
No matter how profound the content I refuse to watch a 20 min video with 10 ads. And I'll give thumbs down as well without watching. So keep that in mind with your next vid please
You're a controlling jerk... Keep that in mind next time you make a comment.
CZcams is a free platform and these people are giving you University level instruction for free. And you're going to complain that they're trying to make a penny off of it. 😒
And your a comment troll. My comment was actually relevent. Your just slinging names at ppl. Boohoo you really got me

You need more training especially for a university. Wow. You don't know how panels are built and configured?
It’s a buck-boost.
This lecture is a more basic introduction. you’re referring to more advanced issues. Gotta learn to walk before you can run.
