MPPT explained (AKIO TV)

[@nhikoid]

Best explanation of MPPT I've come across yet.

[@doctorcollector8676]

Anyone who is able to explain complex subject in the easiest way is a good educator. Thanks a lot for your explanation.

[@AKIOTV]

no problem :)

[@leeziegel7447]

Im 64,Now I know what the purpose of an mppt is. What a smart young man you are

[@Janzer_]

This is the only video that has explained what an MPPT does with clear and understandable language.

[@jameswarner3450]

Good job explaining. They will tell you that a charge controller manages the output current, but nobody explains why.

[@joemacdougall7392]

Just wanted to let you know that you explained MPPT far better than my lecture material. Thanks for the help!

[@Ed.R]

Like the way you used pedalling a bicycle as an example. It suddenly made me realise my automatic shifting system for my bicycle CVT hub is actually like a MPPT for human leg power. Thank you for this.

[@patchnplay]

Great explanation, a bit simplified for a person without electrical background but I love the fact that you explain voltage drop when drawing maximum current. Many MPPT explanations leave this part out and stick to theoretical graphs...

[@tahirali2218]

The most simplified explanation of MPPT, wish you the best. Great work man 👍👍👍

[@ahmadhussainwebshare1001]

Very good video, helpful 👍

[@kymcainday6677]

But what if that specific point of Maximum power outputs voltage higher than the maximum voltage required for the battery? do we need to reduce the duty cycle to lower the voltage even though it is going to reduce the maximum power? Do we need to use dual buck/boost converter where the first one at he first stage tracks maximum power and the other one at the second stage controls specific voltage and current required for the battery? But my concern in having that kind of configuration is the efficiency, because if both converter is rated with 90% efficiency, then having them both in such setup will render 80% of efficiency, 10% reduction from each of them.

[@Lorigato]

[@warperone]

great video. In my case I have sungrow SG10RT, the spec sheet says "No.of independent MPP inputs" = 2 and in terms of "no. of PV strings per MPPT" = 2/1. What would that do if I wire up east and west facing panels on 2 different strings into the MPPT that can handle two string inputs.

[@do_not_reply4784]

[@barryporteous4904]

[@ephiee1]

Power dropped because I and/or V or both changed. What does the controller changes in order to improve the power?

[@dalenassar9152]

GREAT VIDEO!! This showed MPPT from an "electrical" view-point. How about a video on MPPT from a "mechanical" view-point?....i.e. "tracking the sun" and show some curves with those related variables. NEXT VIDEO... perhaps combine the two.

[@strengthwisdom]

Nice video!! Can an MPPT get the 12 volt input up to the optimum votage for a 24 volts system?

[@AKIOTV]

depends on the type of power converter used inside the mppt controller. In theory it's perfectly possible but most manufacturers' implementations are require the solar voltage to be > battery voltage. You can find out on the datasheet of the controller.

[@otofoto]

Then it is boost controller.

[@asimf4505]

[@electrical-sajid]

@@AKIOTV can you share your email ?

[@electrical-sajid]

My doubt was you said that if current is reduced voltage will increase. But in the end we get same power correct ? As P=V*I. So how it affects the power ?

[@AKIOTV]

@@electrical-sajid yes, P = I x V. But that doesn't mean the power is constant. If I draw 2x as much current, that lowers the voltage, but not necessarily by a factor of 0.5. (As you can see in the I-V curve of the solar panel).

[@raomuhammadumarfarooq5421]

does the mppt reduce the life cycles of batteries?

no

[@stellatsering32]

[@stellatsering32]

A question: Does that means the battery can be charged directly by MPPT and inverter is not needed?

[@AKIOTV]

inverters are only necessary to connect to an ac grid. For charging a battery you don't need one

[@stellatsering32]

@@AKIOTV so if we want to charge a DC input load by battery , can we directly charge from the Battery to the DC input load without inverter?

[@psykopat81]

​@@stellatsering32what is your goal?

[@rustyspottedcat8885]

So it is derivation sampling optimization.

How does an inverter with MPPT work when there is no batteries conntected?

[@razamadni5726]

how about mppt designing (proteus simulation)

[@wilsoncabana6346]

If i use 12.4v with 60amp current. Can the MPPT convert the current into volts? Example, i will charge a 24v battery.

[@AKIOTV]

depends which mppt converter.

​@@AKIOTV i will be using a SRNE MPPT sir.. during rainy seasons, especially if theres typhoon and i have to dismantle my solar panels on my roof. I will use that power supply to temporary charge my batteries, incase.

[@aryansrivastava2052]

Thanks a lot sir ..

[@cryptonert9521]

Greetings! I would just like to ask if it would be possible to configure an MPPT that would be able to have 2 input sources, like Indoor Light and Thermoelectric Generator (TEG). If so, do you have any ideas on how to implement it? This would be the possible grounds for our thesis. Thank you so much and I hope you have a great day!

[@AKIOTV]

You could build a double-input mppt device, which is essentially just two mppt controllers in one box. (Although one microcontroller could operate both power converters given it's fast enough.) Connecting the sources in parallel/series won't work, because two different types of power source probably won't have the same mpp, so connecting both to a single input would give you poor performance on both.

[@cryptonert9521]

@@AKIOTV Hmmmm is there any way possible to have a single MPPT only? This would be the main purpose of our thesis, having a single MPPT that would be capable of receiving 2 sources, although not simultaneously. Thank you so much for replying, mate! I highly appreciate it 🙏

[@AKIOTV]

@@cryptonert9521 if they never happen at the same time that should work, as long as they're both within the acceptable range (voltage and current wise) of the controller.

[@psykopat81]

Let's say there is a solar panel that provides 12 volts and a 1.5 amp power (18 watt max). How does the system work when the weather is cloudy, let's say the power of that panel drops to 5 watts, how does the mppt device adjust this? e.g. dropping voltage to 5v and ampere to 1 amp ? or dropping voltage to 10v and ampere to 0.5 amp ? or something else ..

[@the7thhokage287]

You missed a point there, the power isn't constant, I can't say it's 10 watt pv so it can give 5v 2 Amps or 10v 1 amps, we say because of the weather condition and load profile, the volt is 10 V and the current is 1 Amp which will lead to 10 watt power, so for your example, if the voltage and current drops to 5V 1 amp, the mppt can lower the current to 0.5 so the voltage will be let's say 14 V so the new power is 7 watt (as you can see the IV curve isn't linear), or it can lower the voltage to 3 and get 3 amps so the new power is 9 watts, so mppt continues adjusting value of volt and amp by changing the mppt input resistance until it reaches the maximum possible power

[@DiamondAxolotl]

[@vinodbhatt7581]

Thank you sir

[@absolute___zero]

Ok, power is the product of voltage by current. Can you tell me, why do I care about this equation, if on the other end I have batteries, and whatever I put there, it is going to be consumed anyway? Why do I need to balance anything? Do you balance anything when you empty one bucket to fill another? Even if it drops to near-zero voltage, the destination is going to take anything and consume it. So , why do I care ???? Any answer? My dear expert? I can use a step down module and convert any power from the panel to the battery and as long as the voltage stays slightly above the combined voltage of all battery cells, the current is going to be consumed, in any amount. The electrical energy is going to be used to make corresponding chemical bonds to create a higher potential difference between the cathode and the anode, and that is it, why do I need an MPPT device? As long as my controlling logic gives an efficiency above 90% (and you do that by using higher frequency controller) I don't need to pay the big bucks for an MPPT device. A decent PWM will work fine. Who created all this MPPT marketing propaganda, I wonder?

[@AKIOTV]

@@absolute___zero More power means the battery charges more quickly. That is why you care.

[@davebutler3905]

Brilliant teaching skills! The only good explanation on KZbin!!!! The bicycle metaphor is ideal. Torque is a good analogue for current and revs maps to voltage. Well done sir!!! I'm working on an analogue (op-amp based) circuit for Mppt. The algorithm is similar to focusing a telescope/microscope. Do you think it will work if i only monitor and maximise the current fed to the battery?

[@AKIOTV]

Yes that'll do
