Glad you appreciate the time it takes to research these brands and products! Don’t overpay for the exact same controller that other brands offer with “their” logo on it!
Thank you for testing, I just bought the 40A version at Aliexpress and I needed to know that it's actually an MPPT, they have so many cheap PWM controllers with MPPT labels!!
Thanks much sir, just starting out and need something small, not doing solar but rather hydro but pretty much the same game. I'm gonna check out your other vids. Price went up, it's 39.99
Glad you enjoyed! Prices go up on Amazon unfortunately when vendors get low on stock or looks like they’re running out! Amazon penalizes sellers and de-ranks if they sell out! Hydro is awesome, whenever I get spare $ I’m planning on a turbine in my creek! 24/7 energy is appealing for sure!
@@THEOFFGRIDMOUNTAINHOMESTEAD Yeah Ive been on scamazon for 15 or so years. I bought an inverter on there had a $45 off coupon, next day it was 40 after than no coupon lol I was just stating for anyone reading what todays price was, I def am gonna pick one up myself gonna watch it a bit because it will be a few weeks before I get the water wheel done so I don't need it today once a good deal pops up on it I will and if I bother talking about it on my channel I'll give you a mention for advice on this stuff. My elec bill runs $400ish a month for the 7 of us so yeah I'm looking to squash that. My creek is super low right now but for the most time it does pretty well. I'll still keep my grid hookup for things like the cloths dryer and my welder/shop tools but I want 80% of my elec needs to be from water generation. I'm not doing a central unit but modular, every room on it's on inverter so when one does quit the whole house ain't off. I just concreted in a side of the dam that got knocked out a month ago and only have large commercial truck batteries for now but eventually Lord allowing and the creek don't rise I'll get it pieced together. I've scrapped out campers and buses and kept the wiring I have some nice 00 gauge wire already on hand that I have no $ into. Def been enjoying your videos, thanks for being real and not bringing drama and music into your videos, educational and fun to watch/fam friendly, my kids like watching too ages 5-14.
Nice, I want to series my large batteries so they are at a higher voltage. Using them to top off smaller 12V batteries for small 12V systems. That looks like it would work well once I find a way to limit current.
I just got one, also the 20amp. The English is horrible in the manual! Not sure what you are reading. First test today went well enough. Charge controller works.
@@THEOFFGRIDMOUNTAINHOMESTEAD I used an old but unused 24volt panel, and a failing utility battery that I first discharged down to 6 volt lol I didn't see more than 2 amp but this may be all this panel produces. About three hours charging and the battery was holding at 12.5 volts. I'm calling that a success.
Ordered this one on Cyber Monday and wondering if 20 amps is the max input from the solar panels or max output (charge) to the batteries or both? Great video! TIA and keep ‘em coming!
For the money I think it's a great deal. I've had a Northern Tools controller running on my gate opener battery for over 10 years now... the display is barely readable, and I've had to take it apart several times to clean out bugs/spiders... but it still just goes (It's not MPPT, not even sure if that existed when I purchased that thing). I've been thinking of swapping out that battery (next time it dies) for lithium, and so I think I'll buy one of these. Wondering what it's efficiency is, and it is of course a little slow to track... but for the money, and for the application who cares... I own a bunch of these things. My best one updates tracking many times a second, and is 99% efficient, but it dang well better be for what it cost. But for small applications, and startups I think it's an excellent choice, they do generally last forever unless they get struck by lightening or suffer physical damage. I generally put up a small roof just six inches over the box, of all my outdoor ones, to keep the sun and rain from destroying them, and they just go like the energizer bunny. It's likely I'll replace my oldest one (above) due to technology changes before it dies...
I was putting 240 +/- watts in and was getting right at 240 out. They claim 98% total efficiency so very close to if not over spec. It was most likely slow to track due to power supply, I was changing VOC so like it had a different set of panels every time I adjusted the voltage. Same as if an Outback or Midnite sees a new VOC input it stops and recalculates before tracking and charging again. I will have this controller on a set of glass whenever my filming schedule and weather decides to cooperate lol. Try to do a side by side with another controller on same panels to see which can get the most power.
I’ve got them mounted to the wall of my power shed on a piece of 1/4” concrete board/tile backer. Comes with a template to align the screws for installing. 4 keyhole openings on the rear back plate slide over the screws. Hope this helps!
@THEOFFGRIDMOUNTAINHOMESTEAD Thank you Sir. I am mounting mine on a "z channel" to raise them off the mounting surface. It will be in a motorhome exterior cabinet/storage bin. I hooked mine up earlier (60A) version and heard a ZAP!! it's doa....amazon refunded and shipped out a replacement without issue. Hope it gets here by the 4th so I can install it and head to Idaho to do some gold panning 😁
Sorry to hear you had a doa, assuming all the working voltages /PV input were correct? Gold prospecting in Idaho sound like a blast! I do a little gold prospecting myself on occasion. Hope you get everything worked out and have a good time! Best of luck to you!
Very good video brother I got a question to ask you where can I get one of those 60 amp mppt controllers and where can I get that sober box that you got this got the power supply that you can adjust the voltage at can you help me out there please
@THEOFFGRIDMOUNTAINHOMESTEAD Thank you, I will not buy this again, there is an MPPT charger made by a company in my country that has the function of limiting the charging current, and has an additional feature of direct voltage reduction for use without Need battery, same price as this device
does this device show wattage coming from the panels and how full batteries are? just installed my first system, two 12v 100ah power queen batteries, renogy 700w inverter and lion energy 12v 30amp solar charge controller plus 3 lion energy 12v 100watt rigid panels. charged both batteries to full with vevor charger and then connected my full size fridge. everything ran fine for 2 full days. this morning the inverter sounded an alarm and i had to plug fridge into the house. im wondering if the panels couldnt keep up.
It shows incoming power, and gives a decent estimate at battery capacity level! Sounds like your panels can’t get you recharged quickly enough/can’t keep up with load! Average size self defrosting refrigerator/freezer consumes about 1.2kWh to 1.5kWh per day! Get yourself a battery monitor/shunt to start th-cam.com/video/9Wm_r-EJDEY/w-d-xo.htmlsi=57Q7JZ4pyiQvMZOX Get either/best price, they’re excellent and accurate. Also will show how much you’re actually delivering to the batteries! Then look at increasing your array size! Hope this helps!
Does this controller have low temperature cut off? I'm using a Victron and an Epevers controller, they have a cold temperature cut off to protect lifepo4 batteries that don't come with low temp protection.
It has a mounting template in the box. Use that to align/install your screws then the controller will simply hang on the 4 screws. Adjust screws depth to achieve snug fit to wall. Hope this helps!
Is this fully automatic? I mean, do I just set it to what type of battery I'm charging, and it will do the rest? How do we set it to the battery type? I just ordered the 60A version from Amazon. Thanks for your video. It's rare these days to find quality products at affordable prices. Best regards
You can set it to your chemistry and it has pre programmed values or you can customize. The setup is very easy, manual is good at explaining configuration. Add circuit protection (fuse/breakers) proper size wire and you’re good! If you need more assistance, let me know here and I can make a quick setup video. I’m going over lots more charging options soon, I can cover my recommended voltages for different scenarios! Appreciate you watching and commenting!
@THEOFFGRIDMOUNTAINHOMESTEAD Sounds great 👍🏻 Have a look at the Eco-Worthy 40A MPPT version. NS24L40 are numbers on the box. I don't think it's got fans or USB ports, unfortunately. It seems solid made, though. Check it out and compare the two. The build specs, etc. What's very nice is Eco-Worthy does have a tech support team and contact phone number located here in the States. They are a little more pricey, however they have some good discount sales. How many amps fuse should I install, and along the positive to the battery? Or along the positive to my Vtoman vs110 19 volt solar panel? Or both? Thanks
I’ve not had good results with EcoWorthy products neither have some of my friends 😞. So I can’t recommend them. YMMV though. what I do is buy say a 10A charge controller I put a 10A fuse/circuit breaker for cc to battery and go one gauge larger on wire than required. Less resistance/better charging and super safe. For PV to this I would say have a 100W panel rated at 5.57 amps, I put a 7.5A fuse since is next size up from 5A nominal fuse. again super safe conservatively rated fuse way more to it but this best I can do in comment 👍
@THEOFFGRIDMOUNTAINHOMESTEAD Thank you for the tip regarding Eco-Worthy, I won't get it. I hear from some fuses aren't an absolute must have & required. I'll put them in anyway because it isn't overkill. I guess you believe they're totally a good thing, perhaps even necessary to have installed. For both fuses, wouldn't it be playing it extra safe to use slightly lower amp fuses, so they'll blow for certain and well in time? My pv is 110 watt, 19volt, working current is 5.79amp. The short circuit current is 6.07amp. What's wrong with installing a 4amp fuse? Wouldn't that blow before the 7.5 amp fuse you recommend? Slightly lower amp fuse more guaranteed to blow before any damages, right? My solar panel is the vtoman vs110 🙏🏼 thx
Yes but it when the panel is fully loaded you’ll be at 5.79 so 4 would pop. 7.5 is there to protect the wire and device more than the panel on single panel install. I just always fuse/protect any Chinese made products! Whether required or not! Conservatively at that!
I didn’t test for equalization function. Sorry, I don’t mean to overlook lead acid folks, just slips my mind due to everything being lithium centric nowadays!
Did you see the worst battery I’ve torn down? Link to the video th-cam.com/video/FTum_SIE1s0/w-d-xo.htmlsi=D9rqYLxOfS2krcu1
Wow, I was NOT expecting that to really be MPPT. Nice find and review!
Thanks! Glad you enjoyed it! 👍
Very nice budget controller. Thank you for doing the research and finding a really nice controller. It definitely performs over it's rated capacity.
Glad you appreciate the time it takes to research these brands and products! Don’t overpay for the exact same controller that other brands offer with “their” logo on it!
Hello, as always good video , I have a question what parameters to set in this mppt if I have AGM battery ?
Excellent 👍 thanks for the video nice it has the lithium wake-up feature 😊

Thank you for testing, I just bought the 40A version at Aliexpress and I needed to know that it's actually an MPPT, they have so many cheap PWM controllers with MPPT labels!!
Glad it was helpful! They are surprisingly good for the price point! Still no complaints from me, just one of those things that works! 👍
Thanks for this, I just ordered one after going through 2 of the under $25 junk ones.
You’re most welcome! Hope you like the controller!

Definitely a good value!
Awesome review sir. For that price I'll probably pick one up to keep as a backup or to throw in my camp bag since its portable enough.
Thank you! Yes definitely both good options for the controller! Thanks for stopping by, take care!
Thank you. Regarding your review ordered the same in no time 😊. Before have fake MPPT controler and sucks gig time

Good review. Price gets lower per amp for the higher capacity units. The 40 amp looks like a good deal.
I’m strongly considering testing their higher amperage controllers next!
Picked one up, orders are behind on the 20 amp but it look worth the wait. August maybe.
Thanks for the update! Hope when the restock comes the price stays the same!
I recently picked on of these up. do you happen to have any details on how you mounted it to allow the cooling to work? Thanks
I’ve got them mounted to the wall of my power shed on a piece of 1/4” concrete board/tile backer. Comes with a template to align the screws for installing. 4 keyhole openings on the rear back plate slide over the screws.

I'm wondering if this device has a current limit for charging the battery. I have a 30Ah LFP battery, and I don't want it to charge too fast.
Just limit your PV input wattage! There’s no other simple way to current limit the 20A version! Hope this helps!

Can you kindly confirm if it’s possible to use 12-18v solar panel with this charge controller and charge 24v lithium battery ?
Very attractive price. I always expected the cheap chargers to be inefficient but apparently I’m wrong
This one performed well! Surprised me actually!
The cheap Pulse Width Modulation controllers are the inefficient ones!
It may very well be. We didn't see how it tracks an actual solar panel.

Has anybody found out if this has a float add equalizer function for lead acid flooded battery
It has user selected charge voltage options.
Does this controller have low temperature cut off? I'm using a Victron and an Epevers controller, they have a cold temperature cut off to protect lifepo4 batteries that don't come with low temp protection.
Unfortunately no LTC on this one. HQST has a 60Amp that does have low temp cutoff. Hope this helps!
Thanks
