Thank you for checking this out. I just recently got one for my camper, and wondered about the inductor as well. this gadget really is a small, light package. I tested another one which came with a panel I bought, and got results similar to yours. The display on the other one was very hard to read as well, at least this one looks good and is easy to read. One of the parts on the board where the USB plugs are does look like a small inductor, but it would not be enough to do the power conversion job for battery charging, although it probably is enough for the 12 to 5 volt USB conversion. My guess on that huge drop is that it's a waste of money to put panels in series unless you are setting up a 24 volt system. I confess that I did buy it because of the MPPT claim, and did not think I would lose too much if it isn't because of the low price. It works, and looks nice, but they probably should not be calling it MPPT. I installed a different type which actually can boost current, because of the limited space on the roof of my pickup camper. I can't just add another panel to make up for the lack of boost. I am keeping my "perfect suitor" as a spare in case the one I am using now quits. Thumbs up for your time, thanks.
With all those parts inside there I'm wondering if you couldn't add a diode and the coil on the panel side and it would work like a buck converter. Somebody took what could have been done with a few transistor and a zener diode used a microprocessor to do the job.
Thank you for this! You definitely saved me some time and headaches. 😂😂 I was about to try one of these out, but right before confirming my payment, I noticed the heat sync looked like a decoy. I realized I should see if anyone did a teardown! What’s also funny is some of the genuine MPPT controller manufacturers show pictures of this inductor inside (and the PVMs I’ve looked at never bother showing the inside). This product’s video has a thumbnail of the back panel opened, yet all you see are those little pieces of conductive tape and not the inductor! Then you play the video, they don’t even show the inside (including the heat sync taped portion from the thumbnail ). They really went the extra mile to try to deceive. 😂 Have you found a good, genuine MPPT controller that’s cheap yet?
i was just about to purchase this unit thanks for the heads up. i bought another one from wish and it had no inductions coils and i got my $48.00 back. thank again
Good tutorial & review. I know next to nothing about solar controllers, but boning-up as I intend to setup a kit on a new shed build. I've heard MPPT works better in cloudy conditions, but trying to weigh-up costs v benefits before buying. This really helped me. Cheers!
In all honesty I’d suggest putting more money into panels rather than controllers - unless you’re very short on roof space. MPPT is great at maximising what you have in good conditions. But if you’re not using it when it’s being generated I think the better investment is in panels.
@@AdamWelchUK Thanks. Good advice. I think a couple of 50W panels should suffice for my needs. Not planning on using an inverter, as I can use an extension cable from the house for large power draw needs. Just looking to hook up a security camera, some LEDs and a radio for occasional use, and power everything from an old 70Ah SLA car battery that's still in good condition. Might invest in a decent leisure battery down the line. Plenty of shed roof space for panels (approx 10ft x 4ft, south facing). The shed is around 35m from the mains board under the house, a patio, and garden, so digging and installing SWA cable was going to be too time consuming and uneconomical for my needs.
Adam i've got the 70A version and is a simple pwm charge controler. I've made some test with 750w solar array and it works pretty good for a 50$ pwm charge controler
thanks mate, glad i checked out ur video. running a pwm at the mo but wanted to buy and mppt. thanks for the info as i nearl bought one of these by mistake
Bought the 30A model and working fine unless this is a PWM. Also bought the 70A and on this model it dispay the Amps of the solar panels inputs and temperature. Not sure it is a MPPT...
Adam, I have a 12v Application, to run some FANS in my Greenhouse. The 240W Solar Panels I have, are OCV 37.48V and MPV of 29.48. mMy questions is can I use a 48/36volt Step Down Module, which is rated at 12V 20A @ 240 an produce Direct Power to the FANS, or should ......tie in a 20 PWM off of the 12volt side of the Step Down Module? What would be your recommendation? What is the Cheapest 20A MPPT that could work in this application. As ALWAYS your videos are AWESOME ! Any Advise will be appreciated. THANKS
Hi, regarding your video, I ask what append if I install it on RV with following config. AC/DC converter on load connector and battery deep cycle on battery connector. When RV is connected to AC, will current pass from load to battery to charge it?
"Full protect" it says, but I saw no fuse of any kind inside the controller. The Wincong SL-03 30A that I have at least sports an actual blade-style 30A fuse inside, easily replaceable should it blow.
I just bought the 30a version and despite what the manual states, the 30a version is a cut down version with no current display or anything relating to power as it needs amps. I have just posted a quick and very basic review of it on my chanel. Go for higher rating unit.
Another great video Adam..thank you and keep on going with the good stuff! Even our chinese friends managed to overdraw the written PWM on the box they clearly forgot the PWM-Symbol on top of the box (see the video at 3:05) :D greets from germany
Hi every one, I have two and they are pwm! But for the price and my setup i have the are working nice. I have even exceeded the rated amp and it still works ok.
Thanks I am looking for an mppt this one keeps popping up but as you say to good to be true. Also all the sites have only been on ebay for one to two years.
This may be a Random comment. I need help. I have a hoselect mppt charge controller. The input voltage of the battery and pv is inaccurate causing the mppt to sense that my battery is full. Is there any way to calibrate the voltage?
If you are after super cheap and don’t need any other features other than charging have a look at this video... Cheap(est?) Lithium MPPT Solar Charge Controller CN3722 - 12v Solar Shed th-cam.com/video/liYZ5pYOZDE/w-d-xo.html Otherwise the only one I can recommend that I’ve used and is still available is the tracer range from EPEver - they are cheap for the amount of features in my opinion.
Adam Welch Yes go for the epever , it works well, and had user settings witch is great! IAM using it in my RV to charge my DIY lithium ion battery 👍🏻👍🏻. Cheers
@@AdamWelchUK I've been asking for away to override equalization date on the a epever tracer. It seems odd your only chance to equalize is on the 28th what if no sun that day??? Is there away???
IT is a fair Produckt All in metal casting .. not ip water rated like EPever MPPT IT keep What IT promis .. you can't get a farrai for a lada's prize unless IT is stolen .. and you liv in Romania or Poland
Just got mine in today. I decided to watch a review after I purchased it, but before I swapped it out with my old controller. I am so mad it’s not a mppt. The whole reason I bought it. I guess I need to do research BEFORE making a purchase.
This is such a misunderstood subject. A PWM based converter is usually a high frequency switching regulator that requires an output inductor to "smooth" the output current from the high frequency "on -off" nature of the switch to give a constant output current. A basic PWM circuit will regulate only the output voltage and current. An MPPT circuit also measures the input voltage and current to present a load to the PV panel that allows for maximum power transfer. This additional information modifies the control loop of the PWM. The unit you have here appears to be neither PWM or MPPT, but simply a switch to connect the PV panel directly to the battery and then turn off at fully charged. It will work, but won't get maximum power transfer or optimise batter life. Some times the cheap products provide 80% out the capabilities of an expensive one, other time just 20%. This one looks to be more like 10%
thank god i just got my hands on a used MPP Solar Pip 2424MS, big chunky MPPT controler w/ built in inverter (2400w) and AC passtrough from the grid (can also charge the batteries from the grid if needed)
I purchased a 70 amp version of this then found discrepancies online so I contacted the seller and then refused delivery so it went back to the supplier for a refund. I then purchased a EPEVER Tracer BN 40 amp SCC. Yes it was 5 times the price but it works better than any previously owned SCC which were all PWM advertised as MPPT. You get what you pay for.
What's the cheapest MPPT available on Chinese market (as an example AliExpress) that we can rely on? Is there any? I'm building an small camper trailer and right now I'm studying the electrical schema to it... I'd like to add solar panels but Im afraid it will get too costly to mount it.
Funny how we live in a time where in two years, it makes a piece of equipment an antique. Generally, you get what you pay for. Some folks can live with poor performance and lead acid lifestyle. Having said that, I DO have a back-up PWM on the shelf, just in case a quick temporary swap is needed.
Not much wrong with lead acid and pwm if you have a basic or convenience system. Although going mppt regardless of the battery type is best! Fortunately my lead acid batteries didn’t read all the recent hate for lead acid batteries so they’re working really good. Will they go 15 years? Probably not. But they’ll probably do 5 years for $600 instead of 15 years for $1300....and I don’t have to keep them warm in winter.
I have this perfectsuiter charge controller . But facing a problem. I has 4s battery bank and can be charged to 16.8. But this charge controller can be set to a maximum of 15v only. So I am loosing 1.8v charge from my battery bank. Any idea to improve? Thanks Adam!
I have mppt 40A charge controller, in very good day 600w panels in series 24v system it gives 35v just 20 to 35w and 1amp to maximum 2 amp. What could be the reason
If the sun was max, and the charge controller was truly mppt, would the output current be more than the PortaPOW’s limit? Did you know from general experience or previous measurement that the current would be much lower than the PortaPOW’s limit?
Thanks for a clear explanation, once again our little eastern friend's are attempting to pull the wool over our eyes. Buyer beware would be a good name for this auction site.
Good video. Thanks. I use this perfect suitor for my two 12v (18v) solar panels in parallel supplying to 12v battery. Is it better if I use those two solar panels in serial to make 24v (38v) to my same 12v battery? Will it charge more current? Thanks for your quick reply.
Rob Mc Thanks for your advise. I have connected my 3S battery pack to this controller. But facing a problem. 3X4.2V =12.6V. But this controller has a minimum overcharge setting is 12.9V. Will this 0.3v over setting create a problem?
Hi Adam, thanks for another informative video. I have found that there are many charge controllers which are essentially a buck converter which (maybe that why they are called "PWM"?). Since buck converters should have an energy storage device there should be PWM controllers with an inductor. Hence, the presence on an induction should not be a factor for categorization in my opinion. weird
You're mistaken. PWM chargers don't need power conversion to work. These type of chargers basically connect the solar panel directly to the battery at a certain interval and varying duty cycle. That's about it. If a charger doesn't have a reasonable inductor it can't be a mppt charger as this type of chargers definitely need power conversion.
@@egbertegberts5384 I had asked the question a long time back when I knew little about these things wanted to clarify. I know better now. Incase you still want to answer the question (for someone else who might be reading it), the question was: If there was a charge controlled with a buck converter without MPPT ability would you be able to tell them apart just by looking for the inductor.
Thanks Adam, sadly I did buy one and thinking it was an MPPT, great review at least now I know not to so impulsive and buy on raw sellers description, could you recommend an affordable 30A/40A MPPT charge controller, Thanks again Adam, I am now subscribed, Cheers buddy
Maynard Johnson its buck converter. It is variable voltage rectifying module for to turn higher or lower the voltage you want to match your battery charge requirements
However, the timers might make it worth it. See if you can hook it up to the shed and use it to turn xmas lights on at night and off. No need to even put a solar panel. However if you had a 60 cell panel, it would be operating near mppt voltage anyways. I wish they would not put pulses on an off, just hit the voltage and off. But I guess that is for lead-acid. Even if each panel had their own controller you might get more power if a bird poos on your array and breaks the circuit.
OMG WE HAVE THE SAME KIND OF TWEEZERS!! Sad mine are bent at the tip because I tried to dig at some tough plastic with them trying to seperate two tightly clipped together halves of a plastic case :(
I’ve used the EPEver range a lot. The tracer A or tracer AN might be your best bet, or the EcoWorthy 20A MPPT charge controller. Both fairly good value.
It looks similar to the tracer A & AN controllers. Have you checked the tracer 60, 80, & 100amp AN controllers?? Only thing is if I'm spending over $400 for a controller I'd probably spend a bit more and get the midnite classic150! For about $575, I try staying about 10amps under the rating on the tracers. I could use a single high current controller. Great video.
It has a similar lcd and button arrangement doesn’t it? Although I’ve only put my hands on the 20amp tracer models I’ve seen plenty of other videos and images to be confident that EPEver MPPT products do all have decent inductors in them for buck converting.
Can this be used to charged LiFePo4 batteries? I've got 4x 100Ah LiFePo4 batteries in series to form 12.8V (3.2V each) and I was wondering if this controller would be good.
Thanks. You saved me quite a bit. I was thinking about buying this from ebay.
I don't know if MPPT or Pwm , but its works very good for small system. I brought one. Nice Review.

It is always a pleasure to watch your videos. Very professionally created and so very informative. Thanks!
If you connected them in parallel, would the MPPT point of 17V be closer to 12V and you would get higher current ?

@@egbertegberts5384 I had asked the question a long time back when I knew little about these things wanted to clarify. I know better now. Incase you still want to answer the question (for someone else who might be reading it), the question was: If there was a charge controlled with a buck converter without MPPT ability would you be able to tell them apart just by looking for the inductor.
Thanks Adam, sadly I did buy one and thinking it was an MPPT, great review at least now I know not to so impulsive and buy on raw sellers description,
could you recommend an affordable 30A/40A MPPT charge controller,
Thanks again Adam, I am now subscribed,
Cheers buddy
Thanks David. I’m a fan of the EPEver range of mppt charge controllers, but also the renogy rover I tested last year was pretty good too. Thanks again
Overall, thanks for covering this.
What's a book converter though?
Maynard Johnson its buck converter. It is variable voltage rectifying module for to turn higher or lower the voltage you want to match your battery charge requirements
PWM for anything upto140watt Solar Panels running 12v Setup. MPPT for anything over 140watt panels and 24v Systems and up.
However, the timers might make it worth it. See if you can hook it up to the shed and use it to turn xmas lights on at night and off. No need to even put a solar panel. However if you had a 60 cell panel, it would be operating near mppt voltage anyways. I wish they would not put pulses on an off, just hit the voltage and off. But I guess that is for lead-acid. Even if each panel had their own controller you might get more power if a bird poos on your array and breaks the circuit.
how is ut0,ut1 and ut2 in menu ?
OMG WE HAVE THE SAME KIND OF TWEEZERS!!
Sad mine are bent at the tip because I tried to dig at some tough plastic with them trying to seperate two tightly clipped together halves of a plastic case :(
OMG, UNMAZING! 😜
Hi there.
Just a request from France.
Do you have any informations about the ltc3780 Buck boost board? Can you made a test of it?
Thank you.
Hello France! Yes I have two of them. Julian Ilett has made a video or two on them - not sure there is much I can add. Great module I’ve found.
@@AdamWelchUK thank you for the information!😀
Best.
So, have you contacted the seller to clarify this?
What’s their comment?
Thank for the information it was very helpful.
Adam, any suggestions on a REASONABLY priced 20A MPPT ?
I’ve used the EPEver range a lot. The tracer A or tracer AN might be your best bet, or the EcoWorthy 20A MPPT charge controller. Both fairly good value.
When the voltage is pulled down to the lower battery voltage, does the current change and move along the panel’s power curve?
You dont know ohm's law .. do you
It looks similar to the tracer A & AN controllers. Have you checked the tracer 60, 80, & 100amp AN controllers?? Only thing is if I'm spending over $400 for a controller I'd probably spend a bit more and get the midnite classic150! For about $575, I try staying about 10amps under the rating on the tracers. I could use a single high current controller. Great video.
It has a similar lcd and button arrangement doesn’t it? Although I’ve only put my hands on the 20amp tracer models I’ve seen plenty of other videos and images to be confident that EPEver MPPT products do all have decent inductors in them for buck converting.
Can this be used to charged LiFePo4 batteries? I've got 4x 100Ah LiFePo4 batteries in series to form 12.8V (3.2V each) and I was wondering if this controller would be good.
Anything new on the bms front, that I want to emulate
