Do it yourself Solar Night Light using TP4056 Board

- I used TP4056 lithium ion battery charging board on this Solar Night Lamp project with Auto On/Off.
There are two types of TP4056 board, one with battery protection, the other doesn't have. I used the board with battery protection.
I hacked the TP4056 board in such a way that the built in protection circuit becomes auto on/off switch by putting jumper wire on Pin 5 of 8205 MOSFET to the blocking diode towards negative output of the solar panel. So when there is sunlight received by Solar panel, pin5 of 8205 mosfet is negative which turning the LED light Off. When there is no sunlight being received by solar panel, the pin5 will be pulled up to postive voltage by the internal resistance of the board itself, turning the 8205 MOSFET on and the LED light on.
I used 6V/3.5W (0.54Amps) solar panel, 3 pcs 1W LED with 5Ohms/2W in series limiting the current to 0.20Amps total. This is enough that the light lasts overnight. Doubling the battery is preferred as the LED light will consumed around 2.4Ah of capacity of the battery. Solar panel will harvest energy around 2.9Ah assuming of 5 hours full sunlight exposure of the solar panel.
PS: In case that auto on/off function did not work, add a 1N4001 (1Amp/50V) diode in series with the solar panel to the input of TP4056 board. You can connect either on the negative or positive side of the solar panel.
Happy DIY - วิทยาศาสตร์และเทคโนโลยี
Took me 3-4 modules to make it work. Tried with 3-4 modules. Some worked, some didn't. Thanks a lot for this sheer intelligence...! However the over discharge protection doesn't work.
I needed to study this a bit. Looks like you may lose battery protection if you directly connect the Out- to the battery? The over Over Current pin 5 normally prevents the battery from over charging and we sort of hi-jacked the battery protection MOS FET and we are using it for Load. It seems like this design would not stop over current and over charging so protection is lost? Really cleaver use of the 1N4001 diode on Solar- ... I just had to test this and I love this solution! I'm going to look at your other designs. Thanks again.
This schematic was great for my project. Thanks so much for taking the time to share your knowledge. All your videos are well made and easy to understand. God bless you and your family. Happy Fathers Day!
This is sheer genius. Thank you for working this out, so useful. The soldering is very tricky (for me), but I am getting better at it. I can confirm that this definitely works. Thanks again Edmund.
Ed you make it so simple! Love this one. Already ordered my TP4056's w/protection so I can hack away....
Galing nyo talaga sir. mas pinasimple yung wiring. 👍👍👍
I did this today, taking apart from the old standard wiring and putting this all in place took about 30 min, but so far it seems to be doing what i want it to do. I am using this to power a Small 4x4 Post CAP WLED install for kicks.
That is very cool. I think i will make one because i have a couple of small panels and a lot of tp4056 and a lot of leds. Thank you
Happy day to you and your family very thanks. Your video is very clear
Thanks for this, your just to clever, nice one.
The charge protection is bypassed. The module is for 1S not 2S. Solar cell will fry your charge protection chip. Will certainly do that with the 18650 cells without charge protection. Be safe read the TP4056 specs.
May bagong natutunang thankyou
Excellent 👌
Very clear, thanks.
Bypassing wire lead to shut the over discharge protection of the board.
Great video
Nice 😊
According to which formulas were the value of the resistor, the selected diode and the volt/ampere value of the solar panel determined?
Hello Edmund, I tried your circuit with almost the same module, mine has mini-usb. It charges and turns on at night, but it does not shut off with the dw01. It ran the battery down to 2 volts when I noticed it. Does your circuit shut down at low Voltage?
Terminals are switched and in my opinion protection is working as On/Off switch. You can add additional Mosfet N -channel transistor to save protection. That additional cable from pin 5 goes then to the gate of transistor and between out + and out - you should add then drain and source of that Mosfet. Diodes with resistor will go between + and drain. You need to remember to use low gate treshold transistor (for example AO3400A or other). Battery will go then normal BAT+ and BAT -
Simply add one more TP4056 between this circuit and the battery..!
I followed all the steps, it works in reverse, with Sun the LEDs light and with shade they go out. Please give me your comments thank you.
Is it possible to use a separate protection module just in case? What about heat dissipation? Doesn't it overload the Mosfet?
Can I use the Usb to charge the battery if I use the solar energy panel to charge?
Really interesting!
very very good video
It work very good
Sir ed lang sakalam👏👏👍👍
Hello! I tried this and it worked, thanks. I noticed that the blue led never turns on, which made me suspect the overcharge/ over discharge protection is bypassed. I hope you respond.
HI, WHAT IF MY SLOAR PANEL IS 50W , 12V AND BATTERY OF ABOUT 20AH, AND 60 LED OF 1W EACH, WILL STILL THIS SETUP WORK?
Hi There
Will it be possible to charge a mobile device from using a TP4056 lithium charging board? Can i plug a usb mini to female cable on this board to charge my phone?
I did this project and it works ...but i use 3 battery in parrallel connection.
Sir Edmund can I request for the step by step procedure of this circuit...
Hello
I have done all the steps as you explained in the video but I found that the TP4056 Borad becomes very hot due to the heat coming from the transistor
what if you increase it to 12 v by using a steep up, can you do that by plugging in the output of the lamp, thank you
OUT STAND ING. Thanks.

boss yung battery nya po ba pwde ma expand or dagdagan ? halimbawa gawin kong 6 di ba makaka apekto?
supper bro
As u have connected y is a extra wire attached with the IC
OK, let me try it
Why we solder that diode with module ... Please describe
I want to know about led connections
Are they + led 1st + led 2nd + led 3rd
Very good ❤
One of my circuit .the light on around 4 am and switch off when the sun comes.. only one is like that
สุดยอดครับ
Sir Ed pwede po ba gamitan ng cellphone charger kung walang solar panel?
Ye ham banaye hai work acha karta hai
Can use 12v led?
Module ki light blue ho gi after full charge bettry?
I've tried to make the circuit using 36 LEDs with a voltage of 3.7V, the lights automatically turn off when there is light, but they don't automatically turn on when it's dark. why, maybe you can help?
its only avtomatic in first time! then u need on off manualy
Sir paano po magcompute ng battery amps vs load?
Dito po gawin nating example?
Naka on during daytime at naka off during night. Ano po kaya mali sa connections ko? TIA
12v battery connect pannalama bro
can we put 5 led bulb /2 batteries to this circuit
Red led will never shut down because its not charging the battery, with this circuit gate of NPN mosfet is pulled up by negative votage from solar panel, in tp4056 battery prtoection circuit charge and discharge battery from same path, when gate is pulled no current will flow in either direction, at daytime it will not light up led and also will not charge the battery
If the solar cell is dark doesn't the 4056 chip shuts down. Does it really need the diode?
The diode is for solar power reference voltage to the output mosfet
If you would do this with two battery cells in parallel as shown in the schematics, wouldnt you need to have a bms in place ? Also, is the cable connected to the pin 5 the one responsible for the on/off functionality ? Very inspiring and cool video.
bms is needed for only series battery connections. for parallel just make sure the batteries have approximately the same mah and some kind of safety fuse between them if they dont have embedded protection. I also enjoyed the video :)
would the diode protect the solar panel in this configuration?
Diode is cheap, so it is always best to protect your devices or in this case Solar Panel!
Sir pweede po bang makuha ung step by step procedure nito.... Kailangan kac namin
How much maximum no battery connect with this module
Hello. I have this setup with two batteries but no resistor before the LEDs. It does not automatically turn on at night. I have to either disconnect and reconnect the batteries or disconnect the solar panels even though they are not producing any current. Any idea why this is happening?
I saw someone on this channel demonstrated this circuit, same with TP 4056 but he connected the diode in opposite way by joining + side of diode( grey ring) to -input of TP 4056. I still remember he murmured that he salvaged that diode from his broken laptop. Why can't we try to test his method to see if it is correct or not?
Instead of using the Tp 4056 how can we make a board
hello i have some questions most people seem to ask : why is b- connected to led instead of battery and out- to batteries ? is it because tp4056 is limited to 1amp?
what is 5ohms resistor for ?
thank you in advance
Sir, are you here?I want to ask you something and this‘s a great video
Why did you connect bat(-) to load and not the battery. And why connect to MOSFET?
becous he stupid)
Thank you sir
Sir may video kva sa solar light ung battery po ay 32650 o 32700 tulad ng ganyang set up salamat
Sir ilang ohms po pag 10watts?
where do i get 5 ohms 2w resistor
Hi sir ive followed your instructions and it work :) my question is.. will the 4056 protection board still work when the battery is full turn(green) and shut down below 3v?
Yes
Thank you sir :) im a fan of your work. Waiting for my materials to come and make another one of your tutorials. And i love it :)
How can I find this board?
Adding an LDR would make the circuit more efficient
ldr ?
@@mvkboats9879 A simple search on Google would of answered your question. LDR = Light Dependant Resistor
Gumawa po ako kagaya nyan pero pag umaga namamatay naman pero pag gabi ayaw na umandar ano po problema?
Y a extra wire needed to the circuit board saying as wire no 5
sir sa akin ayaw mag off yung led kahit connected na yung panel ?
WHEN DARK IT DOES NOT TURN ON THE LED,WHEN I DISCONNECT AND RECONNECT BATTERY LED TURN ON WHY?
Hello. Thanks for your great work in doing this. I have a question do you think I can substitute a solar fountain pump for the LEDs? The pump
is brushless, input voltage 3.5 to 9 volts 1 to 3 watts.
Yes if the output is above 4V. If you are using the 3.7V battery then you will need a 5V step up boost voltage regulator. 5-6V is best for the pump. Over 7V will shorten the pump life shorter.
I also have water pump wired directly to the 6V 3.5W solar panel for my three bird baths.
www.amazon.com/Driew-3-5-9V-Submersible-Brushless-Waterproof/dp/B01CG2YE6K
All I had to do is cut off the USB plug and wires them directly to the solar panel. No module or battery required. Pumps will run when the sun is out.
@@allumallt thanks.
I meant to ask, I see the battery isn't connected like other people connect it they have it connected to the 2 inside connectors, does it make any difference?
@@steve8939123 I'm afraid I can't help you any further on that. I don't have much experience or knowledge relating to tp4056.
@@steve8939123 2 years late. But the TP4056 OUT+ contact and BATTERY+ are bridged on the PCB. It is the BATTERY- and OUT- that connect differently to the 8205 chip. Check out Big Clives blow vid on this and the brother TP4056 without extra protection (Missing DW01 and the 8205) here. th-cam.com/video/M88e1r8nvYk/w-d-xo.html&t
I use smd 3.7 v and 3w is works without rezistor
If I use a 5 watt pannel then what modification I have to made in this project ?
nothing as long as it's 5-6V
@@ThijsvanUlden will it work if i use a 1W solar panel? it has 6V operating voltage and 3V system voltage
I made the same circuit but with 1N4007 diode and it didn't work but it should work. Any guess what might be wrong.
Check that you connect the battery like on the diagram in the video and not like indicated on the pcb.
you are so smart, the best ^_^ (y)
i dont know much about solar power but dont you need a inverter/controller to regulate the power?
How long does it stay ON during the night?
Depends on solar power, battery capacity and resistor value. With 3,5W solar panel, 2Ah battery and 5R resistor it should be about 10,5 hours.
hey,did the battery leak or exploded by charging a lot?
No. It won't leak because it was charged a lot. The module would automatically stop the current flowing to the battey once its full. But the cell would leak if its defective or its old
@@an_iguana4306 thanks
सर Led को + को + जोड़ के connect किया है क्या
As we have to point a plant of solider of fifth pin y
Led glow kam krti hai is method se direct battery se full glow krti hai
great thanks i fail i got other tp4056 :(
Is 5v solar panels ok to use?
I too have the same doubt. With 5v input to tp4056 and a diode for reverse protection, the output gets reduced below 4v which is not sufficient to charge 4.2 v li-io battery.
I bet you cant do this cool project with 3 cells in series and balance charge them with protection? cheers
kermets ofcourse. You will need a 3S bms if you want to series 3 cells.
I have yet to see one that works correctly and does balancing ?
How to arrange it with 3W 8.97v solar panel
Mitesh Dhanani put a dc to dc step down convertor between tp4056 and panel for stable 5v or put lm7805

My tp 4056charging modules red led never sunt off after I charged 3hours, 🙏plz tal me why it's countnusely charge and never stop with 2000mah lithium battery??
Its the input voltage. Increase it to solve the proble.
Red led will never shut down because its not charging the battery, with this circuit gate of NPN mosfet is pulled up by negative votage from solar panel, in tp4056 battery prtoection circuit charge and discharge battery from same path, when gate is pulled no current will flow in either direction, at daytime it will not light up led and also will not charge the battery
Thanks for the video👍
I'm new to electronics and oldish so all this takes some drilling into the old brain matter😂I don't have a 1N4001 diode In my box of diodes, could I use either a 1N4007, 1N5819 or FR107 Instead, which one would be better? Thanks in advance
how if led is 30watt, what must i change?
All things, because TP4056 is only up to 1A current and max 5,5V input. Buy better solar panel - for example 50W, 12V (or higher voltage if needed), and solar charge controller than you can use 30W LED. Also depends for what voltage is your 30W led bulb made.
But diode is heating up because of reverse biased connection
Y pin 5
Y is a extra wire been soldiered from the ic
This triggers the short circuit protection IC.
Y is one of the wire connected to the tp on ic
It was the input gate of mosfet that becomes trigger to auto on off function
@@edmundbrisenio2286 Which is way easier than the circuit I built for sensing it and I toiled away for hours getting the right sensitivity. Thanks for this. wish I found it sooner.
by bypassing circuits's --ve charging port, you are not balance charging lipo
it doesnt turn off when it's daylight, where the error could be?
and will it work using a 6V 1W solar panel?
@@coolmanx21 yes 6v is fine
@@edmundbrisenio2286 hi i wanna ask again about the lamp, my lamp works fine but at transitions from day to night the lamp needs and extreme condition to be turn on and when transitions from night to day it needs high intensity of light to be turn off as well, do u have any solutions to make that the lamp will tunr on/off at a normal intensity?
