Yes, this happens if the wattage you are demanding is more than panel generation. It's known as converter 'collapse'
Can I solve it using a diode at output side???
@@MdShamim-ui9iy that is something I was about to suggest
@@MdShamim-ui9iy
I think so. Using diode may help to overcome this
Hello I want to know if it's ok to use 12/24v to 5v buck converter with 50w solar panel to charge a phone or powerbank
@@macksuting6263 yes I've been doing that for a while. However it's better to store the solar energy into a battery first. Otherwise, due to fluctuation, the charging cuts out a lot
It never bypasses panel to battery, the buckboost ics normally have a max duty cycle of 90% , and by design there is always a schottky diode in the output.
Number 1 : The battery voltage will never return to the panel.
Number 2 : You should use a Buck-Boost convertor, not Buck Converter and BMS with lithium battery pack, and if panel voltage is low, nothing will happen, your battery will be recharged in boost mode till voltage becomes low at panel at night. Then nothing happens.
I want to use buck converter with 3s li-ion battery with bms. My panel is rated 360w and max current 10a. will I be able to get more than 10a after buck converter? I have seen some tests that show panel voltage drop down to buck converter out voltage.
I also use this module to charge my battery but i used Russian Rectifire before the battery to stop reverse voltage and it works perfectly without discharging,
I don't know what you are saying....
Russian rectifier?
Bro you should use a Buck Boost converter in place of Only Buck convertor
*voltage drops as current requirement increases, the buck converter would have some threshold of voltage due to which it bypasses*
Thank you sir jankari dene ke liye
Dc to dc step down buckconvater se direct voltage kom korke 12 volt bala dc 775 motor fan chala sakte he???? Without battery & without charg controller
Load ko koi problem nehi hoga???
agar morning, evening time mein volt bypass ker raha hay pher ye tu plus point hay, volt kam jo hooty hein ess leye aisy kerta hay
mere pas 12volt solar panel hain 330 Watt without battery use korenge only day time ,chalane ke liye buc converterr use kor sakte hain??? konsa model lena hain
without battery & charge controller Buck convater ko direct solar se connect kor ke 775 dc motor fan chala sakte he ? Motor ko koi problem nehi hoga??
Man liy jie mene 13 volt pe motor chala ta hu lekin Morning & afternoon ko jab voltage kom hoga tab convater or fan ka koi effect pore ga
Please reply 🙏🙏🙏🙏
Ho sake to ek video bana dijiye🙏🙏🙏
Very interesting but I can't understand what t he is saying most of the time , is there a version with English subtitles?
When current (amp) is increased beyond 5 to 6, the converter system bypasses the input to the out put.😢
Sar you can use any SMPS power supply used as a mppt charge controller many power supply start from 30 volt input
Good information bhai
Bhai mppt charger koi sa b ho morning or evening m bypass he karta h
Ashapower use karo
300watts 9amp buck converter yeh wala experiment kare.... Please sir 😍
Usefull video thank you ❤❤
Solar panel 😮se module connect ke bad pwm controller laga do bhai sahab. Proper Kam karega
Yes thinking same
Maybe if we could make sense of your setup. So you have 2 panels in series? How about show us the datasheet on the back of the panel? Show us EXACTLY whats going IN the buck converter before you crank the CC pot to make it collapse. I wouldnt trust that meter....I'd trust your sketchy wiring first
Same problem
Nice One
sir diode lagakar dekhiye...
Good information about buck converter
Pl answer my question
Mere pas nearly 500 watt 24v solar panel lge hen .in the start mene pwm controller lgaya tha. ab 24 v 25 amp. Ka mppt lgaya h (1 week se ) Result ye h peak hours m 11 se 3 m 1 amp current increase krta h .remaining time current or bhi km deta h .inverter 24v ka (150 ah ×2 batt.)
Kya mppt sahi kam kr rha h ?
agar solar panel se 19v aa rahey hon aur current 1.0 amp mil raha ho to kiya is soorat mein hum is buck converter ko amp barhane k liye use kar sakte hain , ?
No .... Us k liye Boost converter hota hai
This is solar panel characteristics.. don't load it further..
is sy solar panel ke voltage barha sakte hain? for example Ziewnic 1.5kw wala inverter jo 80v pr operate hota h. 400 watt ki single 40 volte ka panel ko 80 volt kr k bare inverter me use kr sakte hain ?
Single panel chalao ya tp series karke lagao
Boost converter bhi aise karega kya
Speak english, your Title is english but you speak unknown language
exactly!!! HAHAHAHA
i just downvote it because of the language hahaha
Use ev dc to dc converter best solution
Vo 13.6 tk hi rahata h 14.4 tk nhi jata
what is EV DC to DC converter?
Can i run 775 dc motor
Question is that: if I use PWM 30a controller after this types of buck converter..
What happened there ?
Yes I was thinked about that
You are giving wrong information, plz check again
Solar Cell to buck converter to cut off stepdown 12 v
I use buck converter to charge my 16.8v lithium battery with lithium charger, but I want to buy 300w panel
not clear
Try with bypass diode
Price in pakistan
950
Abhi e acha converter he better than pwm
Pwm se to behatar hai
What? Whaaat? Whaaaaat? Speak english please
isko bike me lagao battery ko nikl do
बिल्कुल सही यह बक कन्वर्टर सोलर से चार्ज करने हेतु बेकार है
You are wrong, mine is been charging my lithium battery fine for over a month now. Is the best for my lithium battery.
Charged a scooter battery a dozen times from a solar panel so.......maybe you have no clue what you are doing...
