Hahaha... that was an intended blooper, specifically to test you! I'm just kidding. Good catch though. At least now I am convinced that you are actually watching our videos..lol Yeah, when you press record, the brain is trying to process so many things at the same time. - Speech, voice intonation, lighting, camera angles, camera movements,....etc. Now, think of composing your technical thoughts, reviewing specs, and now vocalizing them with all of the above-mentioned distractions going through your mind....also keep in mind that I don't have a Hollywood resume😋 I hope this helps.

Wonderful! Yeah, just make sure that you isolate your battery electrically from your vehicle. As an added precaution, you could remove the battery entire from the vehicle. Also, I have only done this for only when necessary or emergency situations. Make sure you are using the right charging voltage and current that is recommended for your battery type. I hope this helps. The Innovati0n Lab 💥 www.theinnovati0nlab.com
Не вижу практического смысла в повышении напряжения до 120в, при таком преобразовании происходят потери и неизбежно снижается ток нагрузки. Если надо высокое напряжение для питания бытовой техники, для этого есть инвертор 12/24-220 с нормальным синусом. Мне кажется это баловство, но оно полезное в плане проектирования dc-dc преобразователей.
Thanks for sharing your opinion. The simple truth about opinions is that we all have one. The premise of this video is to show what is possible with this specific converter case - per its input and output voltage ranges/specs. My guess is that your comment came directly from taking a quick glance at the thumbnail without watching the actual video....yes? The name of my channel is 'The Innovati0n Lab'. Maybe you could read some meaning into that. My video projects are usually inspired by the Diy needs of my audience. This converter has an input voltage range of 10 to 60V and an output voltage 'RANGE' of 12 to 120V. Now, with that said, what you choose to do or not do with that information is totally up to you. Again, I tailor my videos to highlight the limits of possibilities and to inspire innovation... 'self-indulgence' or not, I will leave that for the viewer to decide. I encourage my audience to at least watch a video and then give us constructive feedback. Your feedback was composed with a hint of sarcasm and pessimism, but again, I will respect that as your opinion. Yes, most of us do DIY projects for fun and to boost our knowledge. It is very important to keep an open mind when you neither have an insight into what others are designing nor their needs for high voltage DC power. The assumption that one needs '120V'....then it must be to power a household appliance......then just use an inverter, is a very close minded way of perceiving the rapidly advancing world of power. EXAMPLES of HIGH VOLTAGE DC-DC Applications: 💥DIY EV projects 💥High voltage battery systems and chargers 💥DIY transformerless power inverters!!...etc,etc. Sorry for my tone, but these videos take lots of effort, time, and resources to make. I do not take kindly to someone glancing over a thumbnail and trivializing or disparaging my work. I hold this channel to high ethical and moral standards. Please keep your comments respectful and constructive in the future. I hope this helps. The Innovati0n Lab 💥 www.theinnovati0nlab.com
It is possible, but not with these converters. Unless I decide to modify them, but honestly, it won't be whorth the effort. The Innovati0n Lab 💥 www.theinnovati0nlab.com
Can you recommend a boost converter with low RF noise, birdies, etc.? Preferably a module from Aliexpress, but there are so many. The converter should deliver a maximum of 19.5V and 10A at 13.8V input. It's intended for a mini-ITX motherboard used in an all-in-one SDR. Do you have any suggestions?
It was good video ,but GUYS PLEASE DONT DO LOW VOLTAGE HIGH CURENT SETUP ON YOUR SOLAR ARRAY, it is not beneficial in any means, avoid it if you can, you will need to spend much more on thicker wires, really only solar with that low of a voltage that I have see was 70W pannel in that case if you have 2 70W pannels you will probably not spend that much on hogh voltage battery and you can even use PWM controler becuase it would be prety efficient with around 15V from pannels to 12V battery
Thanks for the thoughtful feedback. This video is basically for those with a couple of lower voltage panels as I showed in the video. Ofcourse if you are building a high power solar array, no one would ever encourage a low voltage system as you will run the risk of high cable costs, horrible system efficiencies due to lots of copper losses and excessive heat dissipation. Your points are absolutely valid. However, the disconnect is that the target audience for this video is the small scale solar project - 200-300W diy solar project enthusiasts like myself...hahaha. In a past life, I had some professional experience with solar panel arrays designed for a 1500V DC power sub-station. Ultimately power transmission at high voltage/low current is always more feasible and the gold standard...but you have to be very knowledgeable to design such systems.
@@emiliorp786 Yes that is actually a reasonable aplication of this, just make sure to set your voltage to max charge voltage, and dont overshoot it (for example if you use lead-acid its going to be 28V max bacuse full charg of one cell is 2v if you have different chemistry you calculate it same way take max charge for one cell and multiply it by number of cells)
Yes, your observation is valid. Sorry for the inconvenience. My previous clip-on mic was too sensitive, and it was picking up all the high-frequency switching noise from the test setup. .....No, It was a mic gain adjustment issue because I tried adjusting the gain, and it didn't work. This issue has been resolved. You will no longer hear this noise in our newer videos. Unfortunately, this video was posted a long time ago. Lots of work went into making it, and there isn't much I can do at this point. Respectfully, The Innovati0n Lab 💥 www.theinnovati0nlab.com
In your previous test with the boost comverter, the issue is not that the solar panel is not outputting enough power, it's that the boost converter is asking for too much power. Try to test it again but limit the output current to a low current at first and start ramping it up. At some point the solar panel will not be able to provide enough power and the voltage at the output collapes. If the battery wants 50A, and then the boost converter will try to provide that current at the set voltage, however, if the panels cannot keep up with the power demand, the panel voltage will drop, and the output voltage of the boost converter collapses. Another thing is that the previous boost converter has a low voltage disconnect, try to set that at the Vmp of the solar panel so when the panel voltage drops below it, it will oscillate the boost converter at that voltage and keep the output steady at whatever power the panel can provide. ❤
Wonderful feedback. 👍👍 However, what you are describing has been the premise of all the video tutorials showing how to use the constant current DC-DC converters as diy battery chargers. To be clear, my point is that this is the same gospel I have been preaching for many years now.☺️ 💥💥💥 My 6-Step Battery Charing process.👇👇👇 1. Determine your battery charging voltage and current - from manufacturer specs. 2. Set the converter output voltage to the recommended charing voltage for your battery. 3. Set the output current limit to a near zero value. 4. Connect battery 5. Slowly increase charging current 6. Observe and take measurements. I have made a few videos on this. Please see the video below as I covered the 6-step process in great detail around minute 2 of the video.👇👇 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WDWJ77WWkXc.htmlsi=IStKu2X45jwmBVVa The video above uses regular power supplies, but the concept still applies.

@@theinnovati0nlab782 Yes, thank you for all the hard work you have done in researching and making videos on DC to DC converters for battery charging, your videos are very informative, and helps out people who are just starting out in this field. May I suggest making a video testing out the previous Boost Converter you reviewed using the low voltage disconnect function as a pseudo MPPT for charging batteries, the board itself is impressive in being able to output a lot of power quite efficiently and is rather inexpensive. It could be a good starting point for people wanting to charge their batteries efficiently from their solar panels, but don't have the budget for an MPPT solar charge controller. This series of yours helps people charge their batteries more efficiently rather than using a PWM solar charge controller. Thanks for the feedback and I await your next videos. ❤️
@SomethingZen0 Another wonderful feedback👍👍👍 I have actually been thinking about retesting the 1500W boost converter as a solar charge controller. However, I have already tested that concept you proposed - as an idea that someone else recommended along time ago (great idea!), but it led to nothing but some really bad oscillations (motor-boating).☺️ But you have now inspired me to do something I have been thinking about.....I may not be able to explain it really well in here, but it mostly has to do with tuning the input dynamic impedance of the converter to better match that of the solar panel......if I am successful, I will make a video about it. Stay tuned, my friend! ❤️ The Innovati0n Lab 💥 www.theinnovati0nlab.com
I think if you modified it a little by upgrading the Wire Guage in the converter and with beefier masfets, I think that would work, oh, and decrease the current while the battery almost reached full point
Great idea!👍👍 I love the way you are thinking. That's the type of mindset we need in our community. Stay tuned! The Innovati0n Lab 💥 www.theinnovati0nlab.com
Just wondering, how could MPPTs reach so much efficiency in conversion compared to typical boost and buck converters, where most of them adapt to a synchronous design to minimize loses, what makes an MPPT so special in converting energy?
Wonderful comment! 👍👍👍 It's essentially everything you just said, plus a layer of somewhat complex software control that implements maximum power point tracking using incremental conductance. Most dc to dc converters use PWM control, but there are lots of high-end expensive converters that can give you very good efficiencies - the question is affordability to most everyday diy hobbyists. The 20A MPPT solar charger shown in this video costs almost $100 with all the accessories. While most 20A off the shelf converters would cost you less than 20 bucks or less. I hope this helps. The Innovati0n Lab 💥 www.theinnovati0nlab.com
Mppt got to be changing every minute to find that sweet spot current and voltage, while buck and boost at a constant voltage ⚡️ in other works so if the v drop buck in stop while mppt follow the v drop for it to work same way
@@b.g.bvoice1142 yes correct, I'm aware of it, I'm just fascinated by the efficiency of MPPTs in converting the IV from different levels, for example a maximum power point of 36v with 11 amps from the panel, that gives you approximate 400watts, How could this SCC convert that IV to the batteries charing voltage such as 14.4v , with minimal current losses in the conversion process, that even the Current efficiency of most buck or boost converters in the market has only a maximum convertion efficiency of around 90-95%. The kevel of efficiency of MPPTs that can reach 98.7% is just unbelievable.
I’ve gone through 6 of these so far. They do the job for a short while but eventually the burn out. Would definitely buy a more reliable version of it if it existed.
I hear you. What type of cooling do you have on your system? What are you using the converters for? Do you have high transient surges from your load? Summary: Make sure you are cooling the converters well. Also, try to de-rate the amount of load you are subjecting them to. Never go with the ratings of these converters that are listed online. For the 1500W units, I would rather apply a continuous load that is less than 1000W on them. Cooling is very important for anything power related. I hope this helps.

ive done extensive testing to see if can boost 12 volt of 72 volt for charging ,but due to limitions iof the device it can only output less than an 1amp
@@theinnovati0nlab782 its the 600watt 15 amp model with the lcd screen i was running it off a 12 volt 19 amp power supply it over leaded with an output of 84 volts just on 2amp

Interesting test! I'm just wondering if your panels can't deliver more than 8 amps and this converter doesn't have MPPT built in so if your budget allows I'd like to see your review of the WZ10020L converter
Thanks for the great feedback. But this was exactly the reason why I added a control test whenever I do this. Did you watch the control test? How many amps did you see coming in from the panels, and how many amps was being delivered to the battery system? I will search for the WZ10020L converter. I would love to review it in a future video. The Innovati0n Lab 💥 www.theinnovati0nlab.com
Thanks a lot for the wonderful feedback! ❤️❤️ We appreciate appreciate your inspiring comment. I fully agree with you regarding the need for solar boost converters. 👍👍👍 The Innovati0n Lab 💥 www.theinnovati0nlab.com
You can do it by adjusting the output current limit - when driving capacitive load or charging a battery. However, for my tests, I use dummy resistive loads, I set the output current limit to the Max point, then slowly raise the output voltage. Power =( V^2)/R This means that if R is somewhat constant, varying the output voltage V will vary the delivered output power going to the resistive load. I hope this helps. The Innovati0n Lab 💥 www.theinnovati0nlab.com
Thank you for everything you are doing. I am learning so much. I'm building an electric gokart and it's almost complete. I have a 16s Lion 4kwh battery 67.2V max. I want to charge it in 1 hour. So I need this so bad. 😂. When do you think you will finish this? I have six HP-1400w 12v server power supplies. Just need constant voltage constant current with over voltage protection. Also, I work with electrical engineers and our power supply engineer said to use tiny Litz wire to get extreme efficiencies from your inductor.
Thanks a lot for the wonderful and insping feedback. I will keep making progress, but I only do it as a hobby project...so progress is a bit slower than I would like. Stay tuned. Your power engineer and I probably live in the same professional arena🤫...hahaha. But he is correct, though. Using tiny multiple stranded gauges minimizes power losses due to skin effect....but then it makes the inductor a lot more expensive and time-consuming to build. This was the inductor design strategy I have shown in my last few videos. 👍👍👍 Thanks again for the wonderful feedback. The Innovati0n Lab 💥 www.theinnovati0nlab.com
Will this be a solar panel? If so, I would highly recommend having a buffer battery between your solar panels and your load. You can use an MPPT solar charge controller to recharge your 12V, then connect the 12V battery to your motor. I hope this helps. www.theinnovati0nlab.com
Im using boost converter for electric car charging from generator... ie 220 from gas generator to dc 500w 12-to 60v works fine and as this advertised to support 1200w(1.2kw) which i doubt.. but ive seen it working fine at 600w with fan.. so can be used for powering bldc controller of electric cars/bikesif its lover then 90v

@@theinnovati0nlab782 Okay, I will watch it more in depth. I am not a native English speaker and I did some jumps in the video timeline. Thank you very much for replying and creating this video contents.
Have you tried adding a PWM SCC to the output of the converter to solve the problem of converter collapse, since the pwm regulates the voltage to charge the battery. And also it would be an interesting topic if adding dc buck converter to convert higher voltage pv panel closer down to the charging voltage and converting that excess vomtage to usable current to charge the battery, since the pwm only steps down the pv voltage to the battery charging voltage without converting that excess voltage to usable current. Please make a video about this, if a PWM can solve the converter collapse issue. A lot of us wants to try alternative ways to charge batteries from solar without using an expensive MPPT, and once they get damage, its hard to find a good technician to trouble shoot their complicated components. Please make a video about this🥺thanks
Great feedback. 👍👍 However, it is not a good idea to cascade converters because it will double the amount of power losses due to efficiency hits. Thanks again for thinking outside the box. The Innovati0n Lab 💥 www.theinnovati0nlab.com

Ok... what about battery to battery? If I have a 51.2v 105ah lithium battery and a 12v 50ah AGM accessory battery in my golf cart... what is best for keeping that 12v battery charged...? A 48v-12v stepdown converter, an MPPT solar controller or a DC-DC charger?
Great question.👍👍👍 It comes down to the transfer of stored energy from a higher voltage battery to a lower voltage one. Any of these devices would work. It's just that you will have to deal with the power losses associated with the process. MPPT charge controllers would be my bet because they are designed for better performance and high efficiencies, which translates to lower power losses. This will make a great experiment.! I hope this helps! The Innovati0n Lab 💥 www.theinnovati0nlab.com
@theinnovati0nlab782 ok, so you think the MPPT will be more efficient, BUT which will maintain the 12v agm battery better... I'm not concerned with loss of energy of the lithium pack... that would be 2 scenarios... efficiency and maintenance... which has better charging profile, the controller or the charger

@@theinnovati0nlab782 okay thanks, some of this kinds of buck converters have minimum voltage difference from input to output, irrespective of their voltage range specs, for say a 15v output would need a minimum input voltage of 18v, coz 17v wouldn't work.
