Another good presentation. Very clear and precise. Thank you. I was thinking of trying that converter ( I have two of them on the shelf ) but maybe not a great idea so you've saved me the trouble of experimenting.
your demonstraation is wrong, you should used 12 v pannels for this test. because the boost covertor only boost the volatges...secondly, there is a step down convertor of same circuit, for this test you must used that one.
Your opinion is rather incorrect. If you don't understand the premise of the video, then you are welcome to ask a question. There is no law of physics that says you can't use boost converters with solar panels. There is nothing that says you must use a buck converter for a solar battery charging application. You started by condemning the video for being wrong, but you failed to provide a convincing design argument. The Innovati0n Lab💥
@@theinnovati0nlab782 step up booster cannot change 34v to 24 v....its as simple as popcorn....form 34v to 24v you must use buck step down....its the specifications of buck. secondly, you must use close voltages for higher performance....its can give you 95% of performance output.
Hi friend, Thanks a lot for such a thoughtful question. 👍👍 The simple answer will be that it really didn't occur to me at the very moment. It would have charged a 36V equally the same - but maybe with a higher charging current. One of the benefits of using a boost converter is that you can basically raise the voltage up to 95VDC if you choose to do so. The only one caveat is that, since the input power is constant, the higher your voltage setting, the lower your charging current will be - and vice-versa.
My question is, if the output current of the DC-DC BC causes the converter to not regulate correctly when you exceed available current from the solar panels, will this also be the case when using a DC-DC BC to power a DC motor directly from solar panels? Your videos are great btw.
Thanks for the wonderful feedback.👍👍👍 Great question. The simple answer is yes. For a boost converter or any power supply to maintain output regulation, you must provide the converter with reliable steady-state power that it needs..actually, you have to be able to provide more than when the converters are delivering to your load as a result of efficiency power losses. This is exactly the reason why MPPT charge controllers are recommended for solar battery charging because solar panels are pretty much fluctuating and relatively weak power sources. So in a nutshell, if the solar irradiance goes down and your load stays the same, the output voltage would crash and this could actually backfeed lots of current to your solar panel....and over time, it will damage your panels. I hope this helps. The Innovati0n Lab💥 www.theinnovati0nlab.com
Are there any non variable DC to DC boost converters? Example would be, if I wanted to boost the voltage to 30V. Im building something that needs a voltage boost. However, I don't want to have to increase it manually. Thanks
Wonderful question! 👍👍👍 I am sure you can find fixed output voltage converters. However the issues you may run into might include high costs and possibly power limitations. The variable output converters should work for you. In your case, the output voltage variability is just something you have to set one time ......and that will literally make it as good as a fixed output voltage converter - irrespective of the input voltage variations. I have made multiple videos on how to make output voltage and current adjustments on these converters. Once you set your output voltage, set you output current (max point...in your case), then you are done.

Thanks a lot for the wonderful feedback. Is this something you have tried and it works? Or is this a theoretical recommendation? I have done this a long time ago and it didnt work. These converters are designed for steady state applications.
It depends on what type of battery you have and your charging voltage setting on the boost converter. I have made lots of videos to explain how the dcdc constant current boost converter works as a battery charger. Please see the videos below. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WDWJ77WWkXc.html
No, if you adjust them to the fully charged voltage of the battery they will lower the current as they approach the set voltage, and will try to keep the battery on that set voltage
Hi friend, Thanks a lot for the wonderful feedback. 👍👍 Honestly speaking, I will encourage you to save your money and buy an MPPT solar charge controller. I have used the Epever controller on multiple solar projects, they work really well, and they are very reliable. Also, they help you save more of the energy from your solar panel. My intention has been to develop a diy charge controller and share it with our audience. But sadly, I have not had the time to develop it. 👍😎
Hi friend, I like the way you think. 👍👍 It is possible, as you might have seen in the video, but it was intended to be just as an experiment. However, I will not recommend you do it. One of the reasons will be that a faulty or failed converter could backfeed the 72V from your battery system to your solar panels, and this could damage your panels.
Were you referring to the boost converter or the MPPT charge controller? The MPPT controller can charge both 12V and 24V. The boost converter has an output voltage range of 12 to 95V. So either of them can charge higher than 12V.
