Question. When charging a battery you should use a pure sine wave inverter to protect the battery. What type of current does it make?

Hello. Which of the EPEVER mppt charge controllers in this video is better? Or are there better brand models than the current models? Taking into account the P/P ratio. Thanks.

cost explodes, nice try but def to expensive

Im a little late to the party here, but i got a few B10k potentiometers - but the reading goes all the way to 4095, and even starts reading values from the other potentiometers if i turn it colpmetely. What am i doing wrong?

They offer both mppt & pwm. Maybe you ordered the wrong one. It basically has the same main functions, so..

Is there anywhere I can buy this welder in the USA without going to Aliexpress. It's almost impossible to buy anything on their site

How do I do it if all of my Mosfets are N channel?

I've got the same problem. South West side rain. Warped 16ft lengths. Can't get any from anywhere so may pin them in from inside. What makes them warp?

Stupid me! I was searching for YX850. Me and numbers, not a good combination.

Also if your aim was garden light. I think a bit of diffusing layer from say a TV backlight inside of that clear plastic would help spread the light out more. I'll see if I can find one of those boxes. Seems handy. I would of put the panel inside of it

Thank you for mentioning the diode in the IC. That was my main problem when I first found a broken garden light on the side of the road. Since I just want them to charge my nimh cells. Is there a problem leaving the load disconnected? I just have it floating on the recent garden panel I found. It has a 5252F IC which is pretty similar.

I did notice its easy to put a battey in the wrong way around, but with 12v it doesn't matter as much because it just doesn't work, so a short circuit owuld just make the 12v into 7.4v??

interesting, i have an 18v /25w solar panel, so the smaller mppt board would put out the required 12.6v to charge the 3s battery pack?, or would i still need a 3s bms board too? thanks . i just want to be sure as i have had a fire with a 3s before lol....

🤩You're a lucky man! Can't find them anywhere on the internet/Ebay Thank you for the explanation!

What was the battery that caused it to fail?

Hey mate, i have this MTTP charger currently hooked up to 3x85ah lead acid batteries but considering upgrading to 1x 120ah lithium battery. Will this controller still safely and efficiently charge a 120ah lithium battery? thanks

This were such an good mppt shame are not made anywhere and almost impossible to find one

Nice to see them open, i learned about that only a year ago or so; I could not find DC ones so been using 2 AC breakers,25 Amp each, for a year now on my 60 VDC solar system, up to 32 Amps; i switch them off manually, only, sometimes several times a day ; it's impossible for the current to go over 32 amps, that is the MAX, so it's not expected that they trip on their own, ever, that is not why they are there; they are there because i need to manually disconect them ( solar panels from the MPPT/batteries ) when i need to adjust the MPPT voltages; this seldom happens; i expected them to not last, but they still work perfectly; cost me 2 or 3 euros each; i use 2 of them, 25A each, in parallel; amazingly they never burned and still worl fine; they are in a place that if they start smoking, or on fire, it does not matter, nothing to burn nearby; i would not do it, otherwise.

so in 5min it says LI battery equalization is --- and time ---, but agm batteries dont need equalization but they are charged like sealed, so can agm battery charged like gel or li but with 14.6V boost voltage

Did you know it's now compatible with EPR (Extended Power Range)? So 140 W at 28 V with the proper power supply. Nobody needs that kind of power, really......but it's cool

Good job

Any clue what all three leds strobing across means? I had one working fine and now the leds strobe across. I thought maybe the thing got wet, so I bought the bigger 5a/10a version and it does the same thing.

Any clue what would cause the leds to strobe? I had one hooked up working fine and now it strobes all three leds alternately. I ordered a 5a/10a version and same result when I hook it up. It works fine on another controller.

Hi, Thanks for the video. Do you think it can be used to charge a 3s 18650 battery pack? Cheers!

Hi sir This controller have auto cut off after full charging please sir let me know

Where i can buy the pcb?

I understand this controller can be viewed by 486 port to a android but i can't get it to work. can you help?

Should have ripped the welds to see exactly what it did. cmon...

I used a YX8018 same circuit but different pin out. I replaced the LED with a regular diode and a 20uF capacitor which developed 10 Volts DC with very low power.

how to connect to android i can't find a vid

My understanding is that both MT50 and MT75 are bus masters, and there should be only one bus master.

Do you know what the max amp draw is from the Load Terminal?

Good morning why not use nickel strips per point and put a bms? That would be easier, right? THANKS

Actually this circuit should work. i once did it for a project a while ago u just have to use a pull up resitor of lower value like 1k or maybe lesser i actually used 1k and it worked fine. BUT interestingly the same circuit on bread board woks just fine even with 1M pull up resitors idk why. STOP BUYING MOTOR DRIVERS GUYS THIS CIRCUIT WOULD COST LOT LESS AND MORE TO LEARN

Can i use 3.7 V battery instead of the 1.25 V?

what`s wrong here? current = (battVolt - shuntVolt) / shuntRes;

tried running the code on arduino............the it display stray '\342' in program

stray '\342' in program

Was hoping for some tests

should be good for low power (5W) portable amateur radio at 12V :)

But that is what it is and not a patch on the TS100

I am pretty new to this module. Can you tell me if it is possible to charge less than 12 volt batteries, for instance 5v batteries using this module? Or it has to be exactly 12 volts output?

1:24 The bad news is that those cutouts, at the right frequency act as very good "slot" antennas! Even when not resonant, the shielding effect of a metal box relies on fairly complete closure. Any hole, including an unwelded seam, that is about λ/4 or larger will conduct noise to the outside surface of the box, where it will radiate. 3:16 Filters are really some combination of inductors and capacitors. Each capacitor has some amount of parasitic inductance, particularly those with wire legs (as opposed to surface mount), past which it ceases to be a useful filter. There is always a frequency at which a particular component is resonant. Wires also present a normal resistance, too, and especially electrolytic capacitors of the sort you used tend to have a maximum ripple current. So although capacitors can work, an LC filtering network needs to be designed with all that in mind. 5:09 ah yes, the bane of every audio engineer's life. That cable is for unbalanced audio which suffers from several different types of noise. One is entirely conducted (ground loops) where especially mains AC noise currents in the shield/ground appears as noise relative to the signal, which the input stage faithfully picks up and reproduces. This situation is most likely to be a problem of common-mode noise on the cable (ie, noise currents on both conductors going the same direction). The right sort of ferrite ring can help with that, too. (And note that choking impedance is proportional to the _square_ of the number of turns.) For this reason, professional audio uses balance (XLR) audio cables where possible. These still pick up common-mode noise currents, but the complementary wire picks up the same amount of noise as the true wire, which the audio input stage cancels out by subtracting the signal on the complementary (aka 'cold') wire from the true ('hot') wire. The result is clean audio, but it doesn't mean the noise isn't there. In this case, the inverter is still very much to blame.

The problem is my speech is messed up and also how much money you have for us. I can't afford it, so I got this. I will do this all the time, Rich Solar.

Noooo that's not how you desolder! It's not safe for PCB's. You should get a desoldering pump.

Very good clip

Hello, good video info! This is a BMS ou Balancer?

How that charge controller working now
