Excellent! I am 68 and as of late my thinking is not as sharp as it used to be (even with some of your videos I have to repeat and listen again. But repetition helps me to understand) I have wanted to get solar panels for my home but everyone seems to talk over my head and I am not sharp enough to ask the right questions at the time.. But you are explaining it so well I followed every thing you were saying.. Now maybe it is because I have grown used to the way you teach.. But I think it is how you explain the basic principles behind the ideas that makes the difference.. I feel confident now that when you are done I will be smart enough to set up a solar system here at the house and know what I am doing and why I am doing it the way I am.. thanks Sorin.. you are a mighty help to me as I imagine you are to many of us.. carry on my friend I appreciate you and your work here.
Finally I understood MPPT. Thank you for simple explanation! Thanks
Sorin, thanks 1000 times for sharing such valuable info and technology in such simple layman terms. You are indeed a very talented and good hearted man🎉🎉🎉🎉🎉
I built our system in 2011 using 16 Sun Electric 210 W panels with Peak Power V 18.3 V and Peak Current @ 11.40 with adjustable angle framework for best sun angle through the year. Parallel 4 bands of 4 series for approximately 48 A at 72 V mid day. Run them into a combiner box and then through 90 feet of 1/0 copper cable to an Outback Flex Max FM-80 MPPT charge controller (fan cooled) charging 2 series strings of 8 paralleled (16 total) L16 350 Ah batteries into 240 v converter. We are completely off grid and this has worked well. You can custom control the absorb charge and the float charge. We are in a very sunny spot in Colorado at 8020 ft altitude so the panels receive good sun. Enjoy your channel.
i hv never think of this way of demonstration.
Very Well Explain, it easy to understand. GoodJob.
Nice! can't wait the tests! So far I used a lot of MPPTs and PWM and I have a clear idea about..but another experience is always welcomed !
Very nice explanation. Thank you so much......
Very good lesson Sorin ,thanks you!
very well explained thank you very much for this lesson
A comment from Italy ... I am really interested in this project to see if it can be compared to airplane modeling, powered by solar cells.
Thank you so much for the teachings !!!
Foarte buna lectia, chiar ma intereseaza sa vad o comparatie intre mai multe sisteme de incarcare
This will be an interesting journey. I build solar control panels and LiFePo batteries for a living. 95% of the units I build are installed in Barbados - I think they will generate a little more power than here in the UK :). Our Barbados panels have 2 charger/inverters running 6 x 24v 76Ah batteries per panel. Our UK panels have a single charger/inverter running 3 x 48v 152Ah batteries. Sorin, have you thought about building your own Lithium battery using cells from old laptop batteries? You must get hundreds in your line of work :) You should move to Yorkshire, it's always sunny in Yorkshire ;P
Nice lesson as always Master! Thx
Hi Sorin, Irealy love your channel you deserve all the best, iwatched your Facebook page ,just to like know you better noting personal, you are my favorite person on internet watch you day and night, honstly you are the best teacher i ever had . Rafi Shamoon
u tackle bout solar system. please mke a video repairing a fault inverty thank you sir Sorin. here from Ph.
While the MPPT controller is tracking the best output power from the panel, does it maintain a constant output voltage to charge a battery? The output power must also be changing by the law of conservation of energy. So something must give at the output of the MPPT controller, either the output voltage or output current.
Great, did not know this was available. Thank you for showing and explaining this!
Un proiect extrem de intresant Sorin, speram la cat mai multe teste, cu diferite chargere solare mai mult sau mai putin specializate. Eu cred ca sistemele de cautare a varfului mppt incerca sa converteasca din panou o tensiune dinainte stabilita de incarcare acumulatori la un curent cat mai mare in functie de intensitatea solara la un moment dat. Insa poate ma insel...
This MPPT based on Thevenin's theorem which states that maximum power transferred to laod when load resistance is equal to Thevenin resistance of source.
Hey sir I like your videos they help me Alot
You know a electron is a electron no matter were ti travels, thous it is always fun to learn "stuff" Pushing 75 and enjoying learnong every day, but I do need a nap. LOL. Blessings. Leo
Helpful video 👍 I like it
For clarification. how do you actually achieve impedance matching in the converter without using resistance?
Because if you would just attach a proper resistor on the input side of voltage converter than you would achieve that impedance match, but it would mean nothing because the power would be dissipated in that resistor and not used by the converter.
You need the power to go to the converter so that you can use it in whatever appliance you want, otherwise you are just wasting it.
So, the answer to the problem lies in the fact, that you shouldn't actually look at it as an impedance matching device. Because for the panel it doesn't matter what do you connect to the output, as long as the voltage and current going out is proper. What you need is not a resistor, but a proper voltage and current going out of the solar panel.
You achieve that by using a capacitor or a coil. They both have minimal resistance, but the amount of current that they are taking is dependant on how much charge they have already loaded.
By manipulating the amount of charge in capacitor or coil through it's loading and unloading you can steer the amount of current it draws and thus you can imitate a resistance without using a resistance.
In this way you can have maximum power draw and steer it to conversion during unloading stage.
I said it in the video, a mppt controller is changing the internal resistance by changing the output current! Higher output current, lower internal resistance and vice versa
@@electronicsrepairschool hi, I appreciate your videos, thanks for them.
I wrote this comment because of my own struggles when I tried to understand mppt for solar panels.
This resistance imitation was the hard thing for me and I couldn't get it.
I wrote it here explicitly in case anyone thinks like me.
Have a nice day
Thank you, i really appreciate when ppl express their opinion or questions
Great! More about solar Systems!
how do mppt inverters track the maximum possible power electrically?
Interresting, series starting out good :), but of course its all just ohms law in the end :D
Im wondering if you will be making a battery backup inverter for adding to your grid tie inverter?, if you do, can you show a 3 fase? :)
I been looking at alot of ideas on how to do this, but i dont see the solution, should be in sun time charge batteries with excess power from solar that isnt used in house, if extra (-house, -charging) put that back grid, in night/dark priority taking AC from batteries, when batteries low, use from main grid (thats my idea anyways).
I have a Danfoss TLX Pro 6k+, in a good day i make 6-12 KW, but i only get to use 3-5KW rest goes into nothing (we pay 2.20 KR pr Kwh, we get 0.12 KR for what we send to grid so its bad to return).
I would think a sweet diagram would save me alot of money in the long run.
I see most commercial sollutions is easy 2-3000$ which is cracy, then might as well buy a real hybrid inverter :P
Great ! Thank you !!👍
Hello
If you have time can you explain the Hybrid system with the super capacitor iknow maxwell have one,i want to know if it is possible to operated air conditioner only with the super capacitor when there is sun especially in warm countries 😎.
Thank you
Sorin. Can we make a mppt controller with either raspberry pi or arduino ?
I don't know but i think they will use the same calculation in electric cars when power is applied to the digital motors?
Thank you M.r
Photovoltaic systems are truly wonderful and can handle any financial situation. A mediocre system that can meet the needs of lighting and other light household appliances (refrigerator, washing machine, televisions, mixer, a small air conditioner, etc.) but provided that not all will work together, can be done at a cost of 6 to 8 thousand euro depending of the quality of the construction materials (Chinese is much cheaper but is it better?) We must forget about energy-intensive electrical appliances that we will have to replace with other types of energy such as gas (electric stove, water heater, maybe even the washing machine if we found a way to supply hot water by turning off its resistors, some clothes ironing presses, etc.). High consumption should also be avoided during the night because there is no sunlight and energy storage batteries have a certain lifespan depending on the degree of discharge (it is also the most expensive material in our system).
Many are forced to buy a rear-end wind turbine to make up for some of the energy during the night or in the constant cloud (as you have in England). There are many things that need to be studied properly in advance to have a proper installation and not need extra constructions and upgrades. Above all, it comes down to the financial issue and how much everyone is willing to spend.
Sorin, you opened a big issue, you started it right from the electric-electronic side (since it is also your specialty), I am sure that you will fill several gaps that were created for me during the establishment of my own photovoltaic system (a small 1000 watts about where I have installed myself in a cottage-residence in Greece).
Well done and I'm waiting for your next videos
Did you get your 100k subs silver play button from youtube?
wow, this is amazing :)
best
I am 68 also. Remember the old days of audio amplifiers, something called impedance matching? If you use an 8 ohm speaker on a 8 ohm output you get max power transfer.
If you use 4 or 16 ohm you only will use 1/2 the amps output power available to be had. You may have a 10watt amp. But You will only get 5 watts out. It must be matched!
If you use a battery with 5 ohm internal resistance you must use a 5 ohm load to get max power transfer out of that battery.
But I'm just an old electronics guy.. I don't talk fast and I read read and believe the KJV Bible.
resistance load not right. must be a battery, then it would last 10v but would not charge because of a 12v battery.
nice sr
👍
You are AMAZING!!!
Cool...
👍🏻
Hello 👋👋👋👍👍👍
❤️👍
??? another youtuber going mad under confinment...
u explain not good about mttp
u abbreviate not good about Maximum Power Point Tracking...It's MPPT, not MTTP ;)
You mean his explanation isn’t good enough enough?
Third
