You suddenly made GreatScott look like a kid playing with toys. You're on a whole other level now with God Tier RU-vid Engineers. I watched the entire 18min video, the amount of detail you've put into this is insane! You seem to know what you're doing, and coming from a fellow engineer working in the SMPS industry it seems you have successfully brought a trade design secrets to the world for opensourcing. Hands down! I would love to see parts 2, 3, 4. This is more fun than watching Netflix

The best MPPT design ever. I am an electronics engineer with a gazillion years of experience but not on synchronous buck, nor do I have any knowledge on solar panels. The peak efficiency of 98.6% does not surprise me that much. The CDS19505 is a great mosfet (low threshold voltage and not too bad of a gate capacitance) and combining it with the high power buck driver makes it a fast switching. I love the amount of detail you provide in both the written tutorial as well as the video. I had to pause and even rewind a few times when trying to track everything on the schematics but I think that just makes this video even better. On a lot of other videos I loose my concentration, with this one I am on the tip of my chair for almost 20 minutes.
@Rob_65
@Rob_65 Год назад
@@sutank.6550 Yes, it can be replaced by a comparable mosfet. But to be honest ... If you have to ask, I am not sure this is a project for you. Don't get me wrong, this is an easy thing to build when using the components specified and the only difficult part there is the inductor (L1) since this is one is playing a major role in the final peak efficiency. But changing parts (or algorithm) in the synchronous buck converter is not something I would advice even for an experienced hobbyist to do.
@Rob_65
@Rob_65 Год назад
@@sutank.6550 To me it looks like you have no clue about what makes a mosfet a good mosfet so my final advice is to get either the specified parts. As soon as you start experimenting with different mosfets and inductors (and selecting the right toroidal core) you will spend a lot of money before you even have a working system. Sorry for being this blunt with my reaction but I do want to prevent you from spending a lot of time and money and end up with nothing else than a big pile of broken parts.
@isabelcuenca5031

The amount of detail from your written tutorial is astounding! I ran a pspice analysis, based on the design you should be able to get 98.1% eff at 31.3A max and 90.3% eff at 40A, which is at par with commercial grade units. This amazed me as you have done a great job in demonstrating diode emulation through the use of h-side n-ch mosfets, something I have only encountered from Victron's high-end line of mppts. The ACS712 was a nice touch as losses were also reduced instead of using shunts. I have read that you were also experimenting with Lem and Maxim current sensors, I hope you would show more about those builds too, I would love to see those! Subbed, keep it up!

Pinned Update Feed: - Detailed instructable written tutorial now available! (check vid descriptions) Correction: - QR Code in the video is wrong, kindly use the one in folder #5 from the GDrive. - R9 & R10 are 100ohm 0805 resistors (typo in the video schematic) Things I Forgot To Mention (Lack of time): - The 12V line is actually 10.625V, it passed my mind that in my other board revision, I changed the supposed 12V buck reg's feedback voltage divider (shown in the schematic) to a lower output voltage of 10.625V in order to decrease switching losses since the MOSFET saturates at 10V after all. One thing to take note of is that the 12V fan will also receive 10.625V, this was intentional since I also had to reduce the current at the U5 since the XL7005A is limited to 0.2A-0.4A. Decreasing the voltage as a result, decreases fan consumption and speed. This explains why I'm using two buck regs: to reduce losses from adding too many linear regs from on a single 10.625V buck reg, the 5V reg which is only feeding the current sensor wasn't a concern since it only took a few mA of current, the 3.3V line on the other hand (which powers a lot of things) had too much of a voltage difference from 10.625V to 3.3V for a linear reg. Thus a separate buck reg was implemented for the 3.3V line and one for the 10.625V shared with a 5V linear reg. - The main LCD display pages only refreshes every second, this was done to reduce the I2C LCD from hogging processing power. Why not move the task to the other processing core of the ESP32? Well it was pointless since Core 0 and Core 1 shared the same I2C bus, processing was not the concern but transmission speed and allocation was. Letting the LCD refresh every loop cycle increases the loop time by 70ms. - Why is the main LCD page navigation slow and the settings menu really fast and responsive!? Once you enter the settings menu, all the charging processes stop for safety. This also gives priority for the menu page to be responsive by allowing the LCD to refresh as fast as possible. Just remember, once you enter the settings menu (press select), the MPPT will automatically stop charging, exiting settings menu would let the MPPT resume back to its charging operation. Issues You May Encounter: - There have been faulty XL7005A chips in circulation, be sure to bench test your XL chips before proceeding. I once ordered 100pcs. from a Shopee.com seller, 15% of them burnt upon reaching 60V. ESD damage from shipment perhaps? - Beware of counterfeit IR2104 ICs, Infineon does specify that original IR2104 chips are 3.3V logic compatible. Some fake IR2104 chips only work with 5V logic. I only found out from my oscilloscope when I was troubleshooting my 3rd board revision. - This is why I only buy from legitimate suppliers like E-Gizmo, LCSC, RS, Mouser & Digikey... If you opt to by from cheap random sellers, just be cautious and be sure to test the chips first before proceeding with a sensitive project such as this MPPT.

Nice build and video, seems like a very well-executed project. I'd just like to raise one concern. With these power levels fire is a hazard that shouldn't be ignored. For commercial gear these voltages would require something like a UL94-V1 or maybe even V0 rating of the case to limit the risk of fire in case of catastrophic failure, otherwise they would not be certifiable. With a regulator being software implemented the failure mode is tricky to determine and catastrophic failure is not implausible. A 3d-printed case like that could easily catch fire and burn down your house if you are not being careful. I do think you get this, but people replicating your work might not, so maybe a disclaimer about the safety issue with the 3d printed case?
@TechBuilder
@TechBuilder 3 года назад
Thanks! Originally, I was aiming for an aluminum enclosure, but the passive-active cooling enclosure design required some milling, which was next level DIY for others to follow. The wide majority of commercial MPPTs use software based regulation, a handful use regulatory certified programmable syncbuck driver chip crossed with an MCU. but I do agree with the fire-hazard enclosure that the project comes with, especially with a system that involves such power levels. Will update the write-ups, add some disclaimers and readme files from the Gdrive. Thanks for this, I really appreciate it!

Great work! I see not much has changed over the years. I built a MPPT board in 2013 and also went with IR2104 and ACS712 back then - Instead of an ESP it used the classic ATMega and serial communication. Sadly a bug caused voltage spikes on the FET-gates, so the circuit failed somewhat fast and the board went to collecting dust somewhere in the "should be completed"-pile. Looks like I really should dig it out and give it another try.

Great project. I built something like this a couple of years ago , worked great , but didn't have all the nice bells and whistles that yours does have. Just some dip switches to set various options. Looking forward to the next installments. I think you may have picked up on something I found out the hard way. If you start your PWM to the half bridge with the batteries already connected , your synbcronous buck converter becomes a syncronous BOOST converter :0) and your input voltage from the panel is boosted up !!! If you redraw the half bridge but treat the output as the input , you will see you have a boost converter:0) I blew up a few things before I figured out what was happening :0) I already had a PCB made , so I changed the software to fix the issue. Measure the battery voltage before starting the PWM and then calculate the PWM value that will give just more than the battery voltage and start with that. Cheers Rob
@robdavis3220
@robdavis3220 3 года назад
your inductor core is a bit under sized. with 30 turns at 20A your Al value will be about half That said , your converter will still work just fine due to the soft saturation characteristics of the core.

Thanks Rob! It means a lot! Yes, I did encounter that! We somehow made an unintentional bi-direction half back half boost. haha 😅 It's not undersized, I'm using a different core material called "Kool Mu" or sendust by Magnetics Inc. It has double the magnetic saturation flux density of common iron powder cores. There's a lengthy explanation from my instructable write-up tutorial. Technically the write-up contains a lot of written stuff that will appear on part 2, 3 and 4. The datasheet based calculation matches the current tested using the inductor test rig.
@robdavis3220
@robdavis3220 3 года назад
@@TechBuilder I realise you are not using a powdered iron core. If you look at the datasheet for this core (0077071A7) the A.T curve shows that a A.T value of 600 (30 turns x20A) your AL value has dropped to 30nH/t^2. Your inductance at this value will be about half (30uH). Your converter will work just fine with this inductance. You should check out the MEGA Flux cores from CSC , they are great. I moved from the Sendust cores I was using to these. Major improvement in performance of the inductor. They were a little more expensive , but now much from what I recall. I like your inductor tester , very cool. There is something you can add to it :0) Add a small capacitor in paralled with the inductor you are trying to measure. With a scope and signal generator you can then find the inductance by finding the resonant frequency. Now when you increase the current in the inductor you can measure the change in the resonant frequency and you can see how the inductance changes/drops under load.

Hello. First of all, I think you made a super cool MPPT. Secondly, I have analyzed a little the scheme given by you, and I have some questions: - The two XL7005A Buck Converters (U5 and U6), from the datasheet it appears that their maximum input voltage is 65-70V. If the photovoltaic panels generate over 70 V, then I understand that the two Buck Converters will burn. In order not to burn these components, is it still necessary to install the D8-1N4007 Diode? Second, the 30A current limitation is only given by U1 - ACS712-30A? If I wanted a higher current, what could I replace this component with? And finally: The voltage of 80 V is limited due to the MosFets (CSD 19505) which work up to 80V / 150-200A. Could I replace them with something else for a higher voltage? without changing anything else in the circuit? Thanks in advance.

I would like to optimally operate 2 differently illuminated PV panels. The sum then goes to a separate LiFePO4 charge controller (also the MPTT controller?). Are you also planning MQTT support so that the controller can also be integrated into home automation such as Home Assistant?

Hello Angelo, I am also an electrical electronics engineer. I really enjoyed the video and found it very helpful. First of all, thank you very much for your effort. I have a request for you, it would be very good and valuable if you could create a video series about MPPT. For example, starting with the basics of MPPT and then continuing with more advanced designs like a 3kW MPPT. This would help both you and us to have more knowledge about MPPT. I hope you take my request seriously. Thanks again

I've been trying to build a copy of this thing for months now. By an absolute mile, the very hardest part seems to be trying to source all the many, many parts needed for the build. I cannot for the life of me figure out how to order all the parts needed to put this thing together. There's a BOM, but it's made of literally 104 different unique parts, which individually need to be looked-up and matched to a source where I can actually order the part. Is there nobody that's put together a cart from Digi-Key, or a service that can take-in a list of generic parts and match them up to orderable parts from a supplier? Like, most of these parts are generic and easy to find - there are services that have libraries of redundant parts! They're VERY easy to find, but very HARD to collate in such large quantities of different parts. I sit here with 5 boards just teasing me. Fully capable of assembling and programming and using, but just cannot find a way to source the parts in any reasonable way. It would take more time to source the parts than to assemble the board!

Boos i have gone through ur intractable write-up and it was wonderfully explained. meanwhile i suggest that in ur future upgrade that u try and move the VOLTAGE, CURRENT to the left side of the SCREEN while the battery % and watts goes to the right and will bring the beauty of the SCREEN. Further more i quote ur last write up on the intractable explanation of the project "UPDATES: My plan for version 2.0 would be to use IGBTs to accommodate 150V or 300V solar panel setups and try to give it a 50A or 100A current capability. There is something called an interleaving synchronous buck configuration, this could easily increase the power handling capability of the MPPT. Coulomb counting for state of charge calculation is in the testing stage of my personal Fugu MPPT firmware. Part 2 of the video will show the complete design process of the MPPT Part 3 of the video will be the in-depth explanation of the Fugu MPPT firmware and the algorithms involved Part 4 of the video will be a montage episode of the tests that we will be conducting on the MPPT unit." with this u have promised to achieve, this ur MPPT controller will be the best MPPT online ever produced. I am proud of ur work boos. May God continued his guidance over u.

I need a clarification on the use of inductor. The video shows use of a 16 AWG wire to make the inductor. But it is claimed that it is designed to handle 33 A of current. However, according to the American Wire Gauge Conductor Table, a 16 AWG can safely handle only 3.7 A of current. Could you please clarify it?
