Great video Brad. I see these no name MPPts on Amazon and always curious on how they would perform. You doing videos on these unfamiliar products is a great help for the solar communities.
Cool you are doing the review videos. You seem down to earth and I trust what you show us. You gave me good advice a few times and you was absolutely right about me liking the victron charge controller. Thanks man
Thanks for the kind words :) I really stress to bring the most accurate info! Glad you like the Victron, they are so nice.
@@BradCagle bro the victron was kinda life changing in a way. I mean I know that sounds weird but when I was having the erratic voltage jumping up and down and charge controller turning itself off and just blinking with the powmr I was worried to walk away from it with it hooked up thinking it might destroy my batteries and when it was the leaf batteries I worried about fires. Now with the victron it just charges smoothly and everything just works.
@@BradCagle I just ordered a powermax 24 volt 50 amp converter charger. I have a 100 amp powermax and it's been great but I couldn't find much out there for 24 volt high amp chargers
Looks great. Everyone needs backup these days. Thanks Brad.
Thanks!
WOW! That is amazing. Thank you, Bard. This will give many people the ability to make their own system at a lower cost.
Pretty exciting! Thanks
i think he called you Bard hahahahaha I never seen his face so maybe he looks like the Bard Wizard from Harry Potter
@@mannyfragoza9652 🤦 My bad, Sorry, Brad.
@@Roll2Videos 😂 it's all good,
Awesome info thank you. Going to try the 50A
nice one you put the video back up, I got one sent to australia, arrived in about 2 weeks, no packaging foam around the box, but it survived very nicely, worked first go, bluetooth connected no issues with samsung s7 android. Haven't hooked up solar or load yet but looking good, a real shame we dont have access to same products you have in usa, our population way way smaller I guess is the issue.
On the bright side we know what is coming eventually.
Yeah, really bothered me they jacked the price like that, so I took it down. But then I realized there's information on this video people can use that have already bought it, so I put it back up. Glad it's working for you! Thanks
I'm guessing this will happen with alot of products you put up, not much can be done about it. @@BradCagle
it is quite a useful video, just a note a small fan blowing on the fins should help cooling if too hot
What an AWESOME review! Thanks!
You're welcome!
Another nice find Brad.
I was impressed with the last 24V battery builds efficiency that I am now building a 48V system for my camper trailer. I'm using a different approach to solar charging - one mppt boost converter per solar panel (4 solar panels) all feeding the 48V battery. A little on the edge, but I think it will work. The boost converters were pretty cheap, but multiply x 4 and it gets up there. Still, I'll have 4 completely independent solar chargers, so this must amount to exceptional reliability.
That's a sweet idea Ben! I just picked up a 20ft camper trailer myself. There's so much crap on the roof I'm trying to figure out how to get the most solar up there.
@@BradCagle Good luck with that. My camper has a roof rack that swings sideways and puts the solar panels in the vertical, so I've had to hinge the roof rack so I can flip it horizontal again. Adding struts at the moment to make the solar panel flip a little easier.
@@BenMitro Oh wow, I'd like to see this.
Good review. $33 is really nice for building a smaller system. I would have bought that instead of the $71 one I bought but haven't used yet.
Yes, amazing price, I hope this works for people on a tight budget. Thanks
Good review. Change the hi voltage cut off from 32v to 29v in settings.
Thank! Yes good suggestion 😃
Hey Brad. I have 2 of these charge controllers one with Bluetooth and one without. The one without Bluetooth is a pain to configure. And the manual that comes with it basically useless as the instructions are tiny and hard to understand. But good value for money.
That's interesting. Yeah I could see it being hard to configure without the bluetooth. Thanks
I bought mines cause of this video. It working good so far
Good to hear!
Great to see an affordable controler, just wary that it's an actual MPPT unit and not a PWM unit with a MPPT markings.
Am definitely interested if it's a true MPPT unit.
It's actually MPPT. I opened it and it has the inductors required for the buck conversion. PWM would not have these
Primary charging is usually done at the absorption setting.
Heat sinks work MUCH better when they are straight up vertical.
E12, 2 hours after install. Book and tech support don't have solution. Another amazing Amazon return
Got the E12 error yesterday. Tried different settings and battery configuration and haven't been able to clear it yet. Unfortunately I'm past the return deadline so it may get some percussive maintenance with a hammer. I'm going on a road trip in less than two days so I may have to pony up for a Victron.
It seems really efficient if it will last awhile seems like a good deal for people just getting into solar especially with the app
Exactly, yet to be seen, It might crap out in no time. Hopefully not.
Alright they jumped the price to over $80 after my video, but now it's down to $44, so I decided to make the video public again.

Great video review & THANKS! But as of 8/24/23, the price on Amazon has skyrocketed to $93.59...a full $60 more than when your video was made. I guess the company is capitalizing on the popularity or originally mispriced this controller. Oh well, I was going to purchase one based on your video, but will look elsewhere or wait for a price discount. Thanks again for your great review!
Yeah, sorry. I have no clue what they are doing but you might check back every once in a while because they seem to raise the price to something ridiculous, and then lower way low. Thanks
That looks incredible value! It's not listed on Amazon UK yet but I could get it with 10 dollar shipping. I'll wait and see if it appears in UK, but still good value even with the postage
Maybe they'll sell a lot here, and expand. Thanks
excellent info on this chanel, thanks for doing it, shame i'm in australia shipping these items to oz makes them not so cheap...........oh well
Thanks, glad the info is helpful 🤠
Haha, I bought the 40 amp one on Prime day. It works well but the load won’t turn back on from the app if you turn it off. You have to press both buttons to turn the load back on…but yeah that higher voltage input is great!
Nice, yeah sounds a little quirky like this one. But seems to work just enough to make it worth it LOL. Thanks!
The 30AMP version of this is only $3 more so might as well go with that lol, im buying one to try out
Agree.
Hope its ok i got the 50 figure it will run cooler and its still 1/2 the cost
Great video period I think I may go ahead and purchase this.
People need to move fast as the price fluctuations are crazy. The 30A is for $47
Yeah, I hope they don't jack the price up to the crazy levels again 🤣
For 33 bucks if it lasted a year I would be happy. Nice!
That's true, I agree.
beginner here, trying to understand voltage.
if i use say 2 100 watt 12v panels, i connect them in parallel?
what if it were 2 100 watt 24volt panels?
also, why would you choose either 12 or 24 volt panels? one is superior to the other?
it went up to $47 but the 40amp seems to be the best deal
Can u series four 12v 100w panels to charger a 12v battery bank. Or you got to parallel the four panels with this mppt charge controller
To me for some0ne who wants something for an Emergency like you mentioned, that charge Controller is perfect. And maybe with a 100 watt panel or two from Harbor Freight and a Lithium battery forgetaboutit you are good to go off grid and fight the NWO
Or better yet, grab a used residential, or commercial panel or two. Thanks
Give the y&h 12v 80a 1800watt hybrid mppt a test, its looks very interesting. About 190$ :)
I'll check it out.Thanks!
Hello Brad, thank you for your videos is great I just had a question I’m trying to download the app on my iPhone for apparently reason can’t find the app. Does anybody know where I can download the app for this product? I’m also having a hard time programming it there is no Customer Support, I purchased mine on Amazon
I purchased Sunthysis 20A
Everything works as described
Except one thing:
For dual light control when I tried to turn it on only 4 hours it still on whole and only shut down at dawn
Please give me an example to make the controller to turn on only a period of time such as turn on at 10:00 pm and turn off at 11:00pm or turn on sunset and stay for 5 hrs
Hi Brad - is there any information on the pin out for the RJ45/COM port on this unit?
How do you reboot this thing? Got a E12 error code and it won't do anything now.
Put a fan behind it
Heat sank is enough no need of fan
Will this mppt work with lithium ion batteries?
What mppt you recommend to buy?
E12 IS battery type issue. I came across code due to this. Set type on physical unit LiFe. Noticed app didn't match, it was LiPo. When I changed it, physical unit changed to LiPo... Error happen. CS and book was no help. After I switched it on unit back to Lifepo4 ,App is moving from SLD or LiPo...within 30 mins. Don't trust app. Major concern is which solar charge is correct... Hopefully it is physically unit.
checked amazon prices today $78.51 for 20A and $100 for 30A
Yeah, bummer they jacked the price up.
I'm possibly gonna buy the 50a one and run it on 12v but was thinking what if you add USB fan to the back of the controller since you have 2 USB ports
Man, I almost pulled the trigger on the 50a. $84 is crazy low. LOL Yeah the USB fan is a good idea, and the USB ports are controlled from the load port so they could be setup to run only in the day I think.
I questioned using this on a 12v RV because of it being positive grounded. I was told by some at Rich solar that it is unusual to be a positive ground but that it doesn't matter as long as I don't ground it or the panels. There is no grounding wire anyway. 3 days in it is working
That is not bad for the price. I wonder if it does better without maxing out the solar input on 12 volt? I believe it said 260 watts max input and it was around 261. I would say either put fan on the load side to help with the heat on it or mount it to an aluminum panel or something to help dissipate the heat. A small 12 volt computer fan should do it I think.
I wanted to check to make sure I got it right, when it says max input 260 or 400 watts or whatever it is rated at, is that the solar panel input or max of what it will put into the battery?
Max that goes to the battery. So 20a x 12.8 = 256w but as you know getting closer to full 13.8+ you would get 276w
@@BradCagle Thanks
@@jw3843 Anytime!
Any one no where I can get manual for this charge controller mine did not come with one
Open it up and see if it has the big copper coils that are the signature of an mppt controller. I've ordered so many different models and they turned out to be pwm controllers.
I did, it has two large inductors. I should have opened it on video, but I forgot.
@@BradCagle Thanks for the info.
@@allynonderdonk7577 anytime!
I find that most Bluetooth apps work better on my tablet than my phone.
Ok, glad it's not just me, Thanks!
Strange this company pictured RV photos in their add on amazon. Not only that but there is no way to contact them
I'm having difficulty configuring this thing. I have a Redodo 12V 200Ah LifePO4 battery and haven't connected the solar panel yet and I'm getting an error 11. The charger controller was $53 when i purchased it last week. I just checked the price for it now and it's $92. I manually selected the LifePO4 battery and the controller rebooted and gets the error 11 right after. Not sure how to fix this.
Probably too late. Best advice. Deal with the crap physical unit navigation. Don't see set anything in app. It don't cross correctly.
En España, isla de Tenerife la tienda bicro online los vende por 69€ de 20A 😢😢😢,,, y son iguales,, se le canvia de nombre ponen volten y listo,,, en Aliexpress 33€,,,espero al menos sea auténtico mppt!?? Lla me sacaron mucho de más del valor!!! 😢
I purchased the 30A Sunthysis, started testing it out. Unfortunately neither of the USB ports will charge anything (tried conencting it to multiple 12v batteries with no luck as well as multiple USB cables and devices) Despite going thru the settings and setting it to "custom" to adjust the charge parameters for my 12v ,3S 18650 Li-Ion battery (which the voltage range I want to opperate it at is 9.6v-12.6v which means im running the individual cells to 3.2v-4.2v) and it will not charge it. Not sure if this MPPT charge controller is good for custom batteries. Looks like it would be good for the 12v/24v LifePO4 batteries though.
Bummer. Do you have the load output turned on? It also switches the USB ports on/off
Also did you set the voltage you want to charge at via the float setting? Thats the one tha matter.
very basic question: do you need to instal a diode between solar panel and mppt if the panel has no inbuilt diode?
No
excellent a bit less voltage loss@@BradCagle
@@namenotshown9277 Yup!
Brad help me out. The manual stats for my 100/40 Sunthysis controller states positive ground. That confused me. Does this mean i cannot use it in my rv which like every vehicle is negative grounded
It's generally considered a bad idea to use a positively grounded controller in an RV, or other negative chassis grounded vehicles/systems.
@@BradCaglewell after calling other charge controller experts at other companies, 3:36 I found someone that sounded like he understood. His reply was the same they don't make positive grounded controllers, but added that it won't matter because I wouldn't be grounding this unit anyway. So positive, negative grounded doesn't matter
The 40 amp is cheaper than the 30 amp by about 15 bucks
These guys keep wildly changing the prices, I dunno what's up 🤣
Did the prices just change??
Yup, bummer
$46 today 8-15-23
Where did you find it for $33
false advertising
@@hasslefree3527 It was $33, they changed the price.
where are you seeing $33 dollars mine is 85$ plus?
They changed the price
They hurried and upped the price. I paid 41.00. It's still 🗑️ trash.
I don't know where you're fighting this for $33.00 it's more than twice that on Amazon I know the videos 7 months old but....
They jumped the price up really high after I released the video, sorry. If I had a way to contact them I would give them a piece of my mind for doing that.
Somebody caught on to the price. 😐
Yeah, looks like they bumped the price after I did this video.
lol price went up like always...once people post it they will make the price go up...
Yeah, bummer.
@@BradCagle for that much I can just spend a little more and get the 40amp one..
@@thatonebeone I agreee
If this is in actuality an MPPT controller, it will be the first with usb ports…
Every other “mppt” controller that has usb ports is just a pwm controller with an odd algorithm. Fake…
I've seen the pwm ones that are labeled mppt you mentioned. This one is real. I opened it up, and it has inductors and the PV voltage is in the correct range, etc..
They keep swinging the price and its now $50.
Ugh, I wish I had their contact info so I could ask them to knock it off!
52 dollars, August 2023.
Oh well tripled in price
Yeah, bummer.
$82.61, what a ripoff.
Well, damn. That's not cool, they bump the price that hard after I do a video.
