The results were non conclusive and consistent for all of them. -the ability to overpanel is a huge feature! I wish I talked about this in the video. What it means is that if you exceed the power input rating, current wise, you will not destroy your controller. It will just produce whatever amperage its rated for. So lets say it has enough power to create 60 amps but its rated for only 40 amps, well it will only output 40 amps, and it will not be destroyed. I really like this feature and its in my BN series "favorite charge controller" listed above. Corrections: 16:14 I switched the two numbers.

will you consider making one for larger units? mighty tempted to get an outback flexmax (not sure on 60 or 80 yet) and would like to see what you think about them
Biggest difference for mppt vs pwm is going to be mismatched solar voltage vs battery voltage. With higher solar voltage input, mppt will be more efficient.
DIY Solar Power with Will Prowse Noticed you have been using Victron in your more recent videos, do you still prefer the metal Epever over the Victron or has your preference changed?
I am a 60 plus old woman trying to learn how to do solar. Your videos are giving me the confidence to start assembling and using a small system. I so appreciate your thorough explanations. You don't use a lot of hype and you don't give just a high level overview. I don't totally understand everything yet but I am so very grateful to your channel. I am hoping that soon I will be traveling around the country using my solar panels to power up where ever I end up camping.
My Aspergers enjoys how you always get right to the point. No words are wasted. Articulate. Knowledgeable. Such incredible efficienct message delivery. A true gift.
@@louc6635 Asperger’s is no longer a clinical term as the condition is now considered part of Autism Spectrum Disorder, since all it ever meant was high-functioning autism. Having said that, it’s really goofy to snarkily say “I thought Asperger’s didn’t exist anymore” when someone uses the “outdated” term for self-ID, equivalent to saying to someone who calls themselves Hispanic, “you mean Latinx??? Haha”
I'm 67 years old embarking on my first van conversion. I'm a retired funeral director with no knowledge in solar energy. I'm learning everything I can on UA-cam. You provide the most informative videos of all UA-camrs. Thank you for making it easy to understand and having the integrity to provide information that I strongly feel can be trusted.
Hey --Why show the junk charge controllers? I use 9 Morning star /Tri-Star 45amp and Tri-Star 60amp charge controllers. These almost never fail-They are top of the line.
@@bobbailey7235 - Curiously, or not, I had "junk" controllers working flawlessly for years! From those I can say the failure rate was EXACTLY ZERO! In fact they have been replaced because of upgrades, or should I say new systems! Trust me on this. As I like to call it, "credit card engineering" is not always better! But it's surely more expensive! LOL 😂
@@bobbailey7235 I think it is because comparing involves comparing. To Not include or test the 'junk', as you call it, is like the school systems that try to 'lose' the scholastic testing of their 'not as smart' students. It would just be trying to play an All-Star game! Ya'll Take Care and be safe, John
I don't know what your background is, Will, But you are by far the best reviewer I've seen for these products so far. Great job! I work in the power industry and like what you are doing. Honest reviews like yours will eventually force manufacturers to up their game and produce quality products instead some of the trash I see out there.
Finding Will Prowse was truly great. Being a complete novice with no prior knowledge of anything electric related, Will's videos are so very understandable. Thank you Will for taking your time, effort to educate we who are interested in living off grid.
Yo yo yo what up guys it's ya boi Mr. Solar Review Man. [shitty music and graphics] Today's video is brought to you by NordVPN. You know, when I'm shopping for shitty Chinese solar panels, I want to make sure the CIA doesn't know what I'm buying and that's why I love NordVPN. Let me tell you more about it for 5 minutes. OK now to the presentation. I was sent this shit for free for a 5-star review on Amazon. Here's how great it is. Don't forget to like and subscribe and SMASH that bell icon. Just smash the absolute shit out of it because I am deathly afraid you will not see my videos because they're crap and won't be promoted by The Algorithm (tm). [shitty outro music and graphics]
In a world filled with so much fraud that people shy away from the truth and even get angry at those who speak the truth, you are a beacon of authenticity. Thank you for what you have contributed to many DIY'ers projects and lives. Many of us have gone from being afraid of going anywhere near these sorts of projects, to building solar + battery systems with attached inverters that we use to power our homes during peak hours, or an emergency or for the best reason of them all.. BECAUSE WE CAN! (Thx to you!)
I love your comment about how the suppliers didn't want to sponsor you because they wanted to be the only ones in the video. It's really impossible to compare unless you have more than one .... LOL!! You make me laugh, and I learned so much I have seen this video before but now I understand more of it. It's been a year that I have been watching you thank you so much for all your hard work!!!
Henry C Cheesy openings cheesy smiles I called that the UA-cam smile 😬 and I did 👍🏾 your comment. He does good work and is very clean with his presentation I’m sure his acquaintances are proud of him. 🙏🏻🙏🏽🙏🏿
Your speaking Greek to me now. But watching your videos I'm sure will learn me. Thank you. You have earned my trust and respect in a short period of time
Thank you for your "out of pocket" review. Glad you didn't cave to the single unit comparison. Honesty & Integrity are hard to find these days. Kudos to ya :)
THIS IS WHAT SOCIETY NEEDS!!......how many times do you start asking questions in shops about their products and they usually don't have a clue!!......and after a while you just stop going too the shops........just go online.......yeah.......this person is making life fairer for the masses.....some times 10 minutes of specialist knowledge that just works well!!.....is more powerful than 7 years of UNIVERSITY......unrelated training....
Very fair comparative review. Shame on the manufacturers for not having enough confidence in their equipment to sponsor your analysis. Thank you for the information. This is an excellent channel.
True. Will explains things in a way that is clear, concise for someone such as I who has had absolutely no idea of how to contemplate a beginning to solar power. I am ready to jump in now, get off grid with my "new" used motorhome, and see this beautiful country....
Thanks for reaffirming my decision to purchase your "favorite". Have been using mine at an off grid cabin for a couple of years now with no complaints.
Thank you, sir. I love the multiple product review. Don't let them change you. I feel like it shows that they don't have enough confidence in their product to be able to have it compared to others. Regardless, you can tell that you really know your stuff. Conveyed by the fact that you're not having to read off of notes, while still being able to relay the information concisely. So much knowledge in one video. Thanks!
Amazing! You stated and displayed your test Lab. You test and compared all charge controllers to each other. You stated which charge controllers should be used based on battery chemistry. You mentioned how to achieve optimal value for your dollar. Excellent, Will. Thank you. And you did all that in twenty minutes!
Bobcat...Everyone should challenge their own assumptions on a daily basis. To do otherwise is to give rise to stagnation and complacency. Do you really believe you can discern who is unbiased based upon the content of a UA-cam video? If only deciphering the human condition were that easy. Shake that cloak of denial once in awhile just to be on the safe side.
Will! I have loved everything you do for years now, but I was a bit shocked at 19:29 “a lady that does need to program it ever in her life” - of all the vanlife couples I know, the ladies are all the ones who have planned and designed and programmed their electrical system!!
Wow Will, you are a diamond in the YT world! EXACTLY what I needed to fill in the gaps of my base. You're a natural teacher, very enthusiastic, and thanks for no crappy music! 5 stars! Buying from your website for all my solar stuff!
I have 8 12v 100w panels 4 in series to a $15 controller to a Led acid bank and 4 in series to a $15 controller to a 100Ah LiFePO4 battery. 5 Months now without any problems. :)
I have had 10 75watt 12v panels daisychained to make 5 - 24volt output panel disharge for over 20 years, and used a cheap 12v/24v PWM controller for most of its life, till I got gifted a 50 Amp RV Power mppt controller and could finally clock amp output on cloudless sunny days at mid day and found my system was making 22 amps so may have been exceeding its capacity (prolly 20 amps). The 50 amp fragged itself so I am considering pushing the panels thru 2 cheap PWMs to lessen the load on each.
My gawd dude, this video is absolutely amazing! From the moment I clicked and started watching, listening to you talk and explain the setup and everything, I could just tell that we were gearing up for a really great, really honest, and very thorough review. I'm now 6 minutes in, and just couldn't resist pausing for a second and giving you some praise man! I wish all guides on youtube could be this educated and well put together. I've been building some 18650 battery packs lately and I'm starting to dive into the realm of solar charging; I'm definitely going to subscribe and will be looking your way for any future Solar needs :) Thanks so much!!
I love how you're just 100% honest and direct to the point. It sounds like these manufacturers are just scummy people who only want to sell a product, and not provide a good experience for the end user.
Outstanding Presentation. Lighting=Excellent. Sound=Excellent. Camera angles=Exclellent. Scripting=Excellent. Pacing=Excellent. Content=Excellent. Also 5 stars for avoiding graphic/video effects that only demonstrate an inflated ego and add nothing to the content. Many video presenters could [should] learn a lot from your work. Well Done, Sir!
Anal? Stop commenting about sound, scripting and content etc. no one cares and it just introduces a psychological anxiety and paranoia of being scrutinised. You’re not the only one that does this and I hope it doesn’t catch on. It’s cringe, You are not a judge or a critic, stop pretending to be.
I got the victron one because its small and it works in harmony with my victron shunt. also it doesnt get hot. mine is inside my tongue box right next to my 200Ah lithium battery with a 200w solar panel going to it and its just chilling out at ambient temps throughout the day. Also the small was very important because i have teardrop and space is very valuable so anywhere i can cut down on size is pretty great. i also like to be able to see the charge stats while driving down the road via Bluetooth.
You are providing a wonderful service, at the appropriate technical level. I love how you are up front, and very transparent when it comes to equipment! I also like the fact that you don’t do any goofy things, no cheesy music, lab coat or fast talk. Young man, you will go far in this world!!! I am new to the Airstream world and looking at adding solar to it. Keep up the great work! I am slowly watching your videos, and already have the book! Thanks... Rob C.
The EP ever 4210, it's a affordable controller and very good quality I had mine for 5 years and never had trouble, works like a clock I never go for expensive staff, there is no need to pay for a brand and it's cheaper to replace.
NO, NO and no! Nothing was "disproven". For goodness sake people separate your myth's from reality! THESE particular charge controller's results are. To and from, these particular models, under this particular conditions! DO NOT extrapolate information based on air &wind!
Ok I'm that old lady that never needs to program anything. Lol thank you so much for the info, I'm completely lost on all this and you have cleared up a few things for me. New sub.again ty
Rich Solar owes you a commission. Because of this test video i bought a Rich Solar 20 am controller. It's been three days and im very happy with it. Thanks again, and greetings from sunny Jamaica. Update: 20 amp Rich Solar charge controller is doing very well. I am up grading with more panels so i need a bigger charge controller and i have decided to buy a 40amp Rich Solar this time and connect both together. Update: I got the 40 amp Rich Solar controller and running both the 20 and the 40 charging the same Power Queen LiFeP04 battery. I am very pleased with their performance.
Damn - I just ordered a Renogy Rover (not delivered yet) and, like you, I believe in using the largest gauge wires possible which means 10 GA to the panels (10A max current) and 8 GA to the battery bank (40A max). I was a bit concerned about the wire terminals and now that I've seen your video I realize the Rich Solar controller is a much better choice. I'm happy Amazon has such a good return policy... Thanks for the review - you've just saved me some grief!
As handybob stated, thinner wires are a bad place to save money. Im gonna use #4 wiring for everything. Im considering using #2 wires from controller to battery bank. The shorter the wires are, the less resistance you will have, and you will want to keep your batteries as fully charged as possible at all times. Also, its important to keep positive and negative wires all the exact same length, or one wire will carry a higher load, especially when hooking the batteries together. I'm going to do this for my whole system., shortest wires possible, all the same length. I'm not sure if thats completely necessary but it makes sense to me so...
@@nicksimon4536 I'm running a pretty simple system - two SLA batteries with probably a max 5A working load though possibly a 40A charging current. The battery interconnects are 4 gauge while the system wiring is #8 to the controller and #10 to the distribution panel. I ended up using the EPEVER Tracer 60A MPPT controller which had no issues with the larger wiring.
I've been using Victron products for many years, they never let me down. Never had a problem with the connections. Over sizing wires is not necessary if you are careful about your connections. I have used some of the cheaper products you mentioned and found that they will fail after a year or two, I then moved to Victron and been happy with that choice for 10 years now. I am sure there are many great products for solar systems but it is always true that you get what you pay for! I do enjoy your videos, keep 'em coming. Thank you.
@Jon Phillips Over sizing wiring at 12V still provides advantage over ‘the right sized’ wire for panel cables. The quality of crimp doesn’t make up for that advantage all else being equal. More importantly to me is battery-to-inverter cabling. 2/0 VS 1/0, or 3/0 VS 1/0 at “full” inverter load adds a level of efficiency you can often feel with your hand by the temperature of the cable. A warm - or worse: hot - cable is clearly not at 100% of its potential efficiency. For example, a 1200W inverter running a shop vac: the advertised peak on the inverter I’m referring to is 2400W, or 200+ Amps at nominal 12V. The ‘correct’ sized cable would become warm to the touch after a period of running the shop vac. I replaced it with two gages larger and that doesn’t get warm ever. I suppose I could look up the tables but I’m sure the correct wire was safe enough. However, safe isn’t enough; on a small system that lack of temperature rise in the cable spells “more efficient.”
Great video! One other very important test is the amount of RFI they put out. RF Hash that ruins emergency communication and Amateur radio reception. As well as Shortwave and standard broadcast AM. A simple test is to bring a portable AM radio into proximity with the equipment and note the amount of static that is generated from the device to the radio. An important factor when choosing a controller for communication setups. Thanks!
One comment, one request, and one suggestion. Comment: Great job on all of your videos! No wasting time with intros, fast paced, edited, info packed, pleasant delivery, and more, as per all the other comments. Request: Compare real world performance of 4 x 100 watt panels in series versus parallel. Series connections good for producing power early and late in the day when voltage would otherwise be insufficient to begin charging versus the performance drawback of not being in parallel. Good to know best solution on sunny day, on an overcast day, and a day with intermittent clouds. Suggestion: You use the word "cheap" to mean both poor quality and low cost. Although not necessarily confusing if the listener pauses to weigh context, there is no other word but "cheap" to represent poor quality, so that is the proper term. The word "inexpensive" is best for low cost.
My head is swirling right now with all the info. But I'll sort it all out. I'm doing a van build and will be putting about 300-400 watts on the roof. And probably 2 100ah agm batteries to start. Your videos are a wealth of info, thanks.
you are the boss man! I used to sweat out of frustration trying to learn these type of things in school. You make me learn, without the sweat and the frustration. Thanks alot man! Really appreciate it!
This is a great comparison video. It makes things clearer by having the other brands on hand while reviewing them. I'm a noob to solar so this was very helpful, thanks
Went camping last week with a couple of yellow top optima car batteries I hade laying around and a cheep mppt from Amazon and 200 watts of solar and it ran my 12v refrigerator /freezer all week, no problem, it was a fun project to put together and no running out of ice.
Glad u mentioned that multiple chargers won’t “fight” each other. I want to add a few panels to my RV. If I’m not at camp and mama wants to run the generator for the microwave or air conditioner, I wondered what would happen when the A/C powered kicks in but senses the power from the solar panels. Which one would win or take over?
I think its important to also remember this test is done on products over the course of only a couple days. Anything should output somewhat evenly out of the box. But how does it perform over an extended length of time? I've replaced a LOT of 6-18mo old renogy controllers for a number of different reasons in solar systems in campervans, but have never had to replace a Victron. How do the outputs vary in hot climates? Cold climates? Still a great test to start with!
im in Aussie would like a video on setting up basic solar system with lithium 200 ah battery for a caravan ,just not sure what controller to use ,i just love your videos cheers
Use Victron! The 100/20 reg he uses in the video is very small and most of things he complained about, are not an issue once you go to their bigger regulators. And you can plug in a display via the ve port on the bottom of the reg, or even a GX color screen that will take multiple Victron products. What solar array are you going to use? I live in Australia in NQ.
U really have it together !!! I love the way you explain all the details, you are a great teacher, I'm glad I found your channel. Thanks William Orange county, ca.
I love the way you teach. You know your stuff and confident enough to not have to confuse people with to much technical jargon to show how smart you are well done !!!!!!!!!
I bought the Renogy Rover MPPT for a portable solar setup for ham radio. The Rover absolutely destroyed the ham bands with interference. Then I bought the Victron MPPT - it is radio silent. no issues using it while on the radio. That's why it cost more. Much better filtering.
So what is the controller for? You begin way over a beginner' s head (me). And, how would I build or design a solar thing to work for my cabin from what you are talking about? Far too complicated, do I put all this is a wooden box under the panels ? What do I do with this moderate/advanced knowledge you give us, would seem to be good for a tech person, but what about us?
I think he means a beginner's guide to the controller component of the system. This guy is good if you're a beginner though, if recommend watching more of his videos and your cabin will be electrified in no time.
This is all beginners level, in fact very basic beginners level! If you really feel the need to get deeper into the subject! I do advise to study a little bit more than a short YT video can provide! There's enough knowledge online! As well as on books! ;-)
In simple terms the controller allows solar panel output to run thru the controller and then output energy to the batteries. Assuming you have lead acid batteries or even liFePo you need to set the point at which the controller stops pushing power to the batteries OR....your lead acids will boil out the electrolyte and fail prematurely (past 27.5 v on a 24volt battery setup (the float limit), or 28. 5 v on a LiFePo setup or you can damage those depending on the battery). So it is a limiter to keep from destroying or harming your batteries.
GREAT JOB! It's easy to see that you are professional and very knowledgeable with a great style and energy. Also appreciated that you don't have a cheesy intro and are not into self-promotion just for ego sake. Nice job, I subbed right away. Great information that's well laid out and different testing methods are explained. A shame the manufacturers won't support your efforts but you tell of all their cheating and point out their shortcomings - not hard to see why they don't like you. But I sure do!! YOU ROCK!! Please keep them coming - I'm just learning!
I used the little/cheap charge controller to on a portable system with one panel and one battery and a timer to water a small, remote orchard in Idaho. It worked very well for that purpose.
Ive got the "small crappy one" on my boat. Works perfect on the 120watt panel charging the 130amp Carbon Lead house battery. You can even programme the output to run for different times from 1hr up to 24 hrs. I use my one to run a fuel polishing pump 4 hours per day while i'm away from the boat. Keeps the diesel nice and clean as well as keeping the house battery at optimal float voltage.
Quick summary, then "...and yeah, I'll talk to you guys later, bye." Perfect outro, thanks for that. Any updates within the past year to any of these? I'd be curious to know. Also, I know it's only 1 compared to your current amount, but you've earned a sub with this and a couple past videos, thank you for the content and for satisfying my curious mind. I'm an electrician currently planning a setup for random things, not quite to live off-grid or anything but for other experiments/hobbies, but your content's much appreciated.
Man I'm sure glad I stumbled across your channel because you explain this electrical stuff in a way I can understand better than anyone I've ever seen. Not saying that others aren't good but you would be a great teacher. I'm going to install some panels this summer after my roof has been reroofed as soon as my roofers get to doing my roof. Soon anyway. I'm encouraged. I can start off doing this with the good stuff and still not break the bank. I'm happy.👍 I'll get your book as soon as I'm through posting this. I'll be in touch. Thanks man.
I’m just getting started setting up a support vehicle for my projects. Since the vehicle (‘92 GMC Truck) will be outside and is a service vehicle, I’m planning on putting two large 250AH lead acid batteries in a large toolbox on the roof rack (fire proofed and insulated) and connecting your favorite charge controller to them. I’m planning on using one 250 watt solar panel on the toolbox, and possibly two inverters, behind the seat (one for just general 110 use in the cab, and the other wired into the automatic cold weather heater and engine block heater, coupled with an AGS switch for the dedicated onboard generator.
Just as a suggestion, you should think about creating a shopping list in Amazon for components that you recommend. It would make it easier for the your viewers to customized their own setup and be confident on getting their moneys worth. Thank you for sharing your knowledge.
Thank you for your integrity and not just going with one brand but buying them all to test for us! :D That alone is reason to sub! Thanks for the vid! :D
I have one remaining question - What is the fascination with these screw-pinch connectors among manufacturers? I'd prefer good old screw-type barrier strips with crimped lugs on the wires.
Great info. Very good review. Just got my EPEVER 40a controller w/ MT 50 remote from Amazon. Going to hook it up this weekend at my cabin. Replacing a Renogy 20A PWM
Hey can I ask you something??? How’s that new epever working out for you???I’ve been looking at them,,,,I bought a 60 amp Renorgy commander a couple years ago and it only last about a year and then it went out on me and Renorgy wouldn’t make it right,,,they really didn’t care,,,I paid over $500 for it,,,,big rip off,,, I’m thinking about buying a new charge controller but I don’t want to buy a piece a junk,,,would you say your new 40 amp here is worth it?????
Thank you, I've been trying to figure out what type of charge controller I need for my lead acid battery bank. You've answered my questions. I have 4 deep cycle RV batteries and 4 AGM batteries [which were given to me from a friend]. So my plan was to charge each pair individually and then move to the next. With the purpose of being able to re-charge my phone, portable radios and various batteries around the shop, plus being able to have DC lighting around the house. I have some cheap and inefficient panels hooked up. I have a portable generator hooked up to my panel - but if I ever run out of gas, I want to have some means of charging. But in the end I plan to get a EcoFlow Delta and portable solar panels - I'm going with the KISS method. Maybe I'll give my battery system to someone on a limited budget and let them follow your recommendations. You do a good job explaining some very complicated concepts [for my knowledge background] thank you for the work you put into this subject.
Your channel is great! I’m building an off-grid workshop that I was going to “do something simple”… a fridge + a few lights. You’ve given me the confidence to do something much better and I know I’m buying quality components.
NO, No, no! They both have their perfect spot for existence! Your very incorrect "30%" statement is as erroneous, as the conclusion regarding this test! Please do not assume things based on short and obviously incomplete information! This particular test was designed, by chance it seems, with the perfect conditions for a PWM controller! That's it! Nothing more, nothing less! Exactly the same way, the test that showed you the "30%", was designed to show that result! If there was intention on the design or not, that's whole different ball game! Most of this tests are made by amateurs, with a lot of chance involved. Instead of a lot of knowledge! This video is no different! Seems innocent enough! Well, than there are the pro's who really want to show you a specific result. And cook the test parameters to show you exactly that! ;-)
I had hoped to see a 30% increase(I always hear about it), of the MPPT controllers over the PMW controllers ... but the increase was very negligible. Is this because the panels are close to 12 volt output?
This was tested on single solar panel use...mppt benefits come in to there own for multi solar panels using parallel and series or both linked. Also some of the cheaper models don't show an accurate reading if you put a reader straight to your battery.
I have a portable foldable 120w setup for my motorbike and even though it came with a PWM, went out and bought a MPPT after viewing a few videos. Now that I have seen this video I feel even better about my setup.
Made the mistake of going with Renogy everything building an off grid tiny house. Once I got the house in place in rural Kentucky my mistakes became apparent. Renogy's tech support is non-existent. You have to talk to a call center and trust that person with no technical knowledge to translate your question to tech support and then translate their answer back to you which takes weeks. Your videos have saved me. The only thing Renogy ever tells me is that I need to buy another piece of equipment. I'm currently running two 500 W solar arrays through 40 amp controllers which are run in parallel to my battery bank. I switched from a 3000/6000 modified sine wave inverter to two 1,000 w pure sine wave inverters. One runs constantly for my refrigeration the other I only turn on when I need to run a small appliance. Renogy actually told me that none of their controllers could be run in parallel except their most expensive one which was complete BS. For those times when it rains for days I have a smart charger which I run off the 3000 watt inverter which is connected to my diesel truck. Thank you for the education.
Thanks Will, i lover your videos. I am currently in school to be an Electrician at Los Angeles Trade Tech College and our professor uses your video for us to learn about charge controllers. Thank you
I have that little one, I use it for a solar panel to keep a box truck batteries charged. one panel 100w, it works great for my basic use. Thanks for this great video

Solar Charge Controllers I recommend for most people: www.mobile-solarpower.com/solar-charge-controllers.html
Other things I did not mention in the video:
-night time, or stand by consumption, was .4-.6 watts for all the charge controllers, so I didn't mention it. The results were non conclusive and consistent for all of them.
-the ability to overpanel is a huge feature! I wish I talked about this in the video. What it means is that if you exceed the power input rating, current wise, you will not destroy your controller. It will just produce whatever amperage its rated for. So lets say it has enough power to create 60 amps but its rated for only 40 amps, well it will only output 40 amps, and it will not be destroyed. I really like this feature and its in my BN series "favorite charge controller" listed above.

Bro i want buy battery bro SECOND HAND NISSAN LEAF BATERY
Biggest difference for mppt vs pwm is going to be mismatched solar voltage vs battery voltage. With higher solar voltage input, mppt will be more efficient.
@@eZiggy100 agreed. Covered that in more detail in my other videos
DIY Solar Power with Will Prowse
Noticed you have been using Victron in your more recent videos, do you still prefer the metal Epever over the Victron or has your preference changed?
I am a 60 plus old woman trying to learn how to do solar. Your videos are giving me the confidence to start assembling and using a small system. I so appreciate your thorough explanations. You don't use a lot of hype and you don't give just a high level overview. I don't totally understand everything yet but I am so very grateful to your channel. I am hoping that soon I will be traveling around the country using my solar panels to power up where ever I end up camping.
Get it girl. Will is the best.
Me, too!!! Same age group as well! Thank you, Will!
I read this in a little old lady's voice lol
57 here, just bought a panel for a pool heating project, controller next...what to choose!!!??? First time doing this!
@@jahjoeka 😂
The companies don't like your videos because you give honest reviews. That's probably why you have nearly 900,000 subscribers.
My Aspergers enjoys how you always get right to the point. No words are wasted. Articulate. Knowledgeable. Such incredible efficienct message delivery. A true gift.
I thought Asperger’s doesn’t exist anymore?
Maybe do a little research @@antpoo
@@louc6635 what’s research mean
@@louc6635 Asperger’s is no longer a clinical term as the condition is now considered part of Autism Spectrum Disorder, since all it ever meant was high-functioning autism. Having said that, it’s really goofy to snarkily say “I thought Asperger’s didn’t exist anymore” when someone uses the “outdated” term for self-ID, equivalent to saying to someone who calls themselves Hispanic, “you mean Latinx??? Haha”
@@skoto8219 I know who asperger was and why the term isn't used anymore. But the condition still exists.
I'm 67 years old embarking on my first van conversion. I'm a retired funeral director with no knowledge in solar energy. I'm learning everything I can on UA-cam. You provide the most informative videos of all UA-camrs. Thank you for making it easy to understand and having the integrity to provide information that I strongly feel can be trusted.
Hey --Why show the junk charge controllers? I use 9 Morning star /Tri-Star 45amp and Tri-Star 60amp charge controllers. These almost never fail-They are top of the line.
@@bobbailey7235 - Curiously, or not, I had "junk" controllers working flawlessly for years! From those I can say the failure rate was EXACTLY ZERO!
In fact they have been replaced because of upgrades, or should I say new systems!
Trust me on this. As I like to call it, "credit card engineering" is not always better! But it's surely more expensive! LOL 😂
@@bobbailey7235 I think it is because comparing involves comparing. To Not include or test the 'junk', as you call it, is like the school systems that try to 'lose' the scholastic testing of their 'not as smart' students. It would just be trying to play an All-Star game!
Ya'll Take Care and be safe, John
You are, young man, one of the most motivated and enthusiastic individuals in the realm. You will go far, pilgrim!
I don't know what your background is, Will, But you are by far the best reviewer I've seen for these products so far. Great job! I work in the power industry and like what you are doing. Honest reviews like yours will eventually force manufacturers to up their game and produce quality products instead some of the trash I see out there.
He's a mechanic like myself. He knows how to think since he has a mechanical mind. People like us think outside the box from the inside of a bag.
Finding Will Prowse was truly great. Being a complete novice with no prior knowledge of anything electric related, Will's videos are so very understandable. Thank you Will for taking your time, effort to educate we who are interested in living off grid.
The beginning got me hooked instantly. (No intro music. No BS.)
Yo yo yo what up guys it's ya boi Mr. Solar Review Man. [shitty music and graphics] Today's video is brought to you by NordVPN. You know, when I'm shopping for shitty Chinese solar panels, I want to make sure the CIA doesn't know what I'm buying and that's why I love NordVPN. Let me tell you more about it for 5 minutes. OK now to the presentation. I was sent this shit for free for a 5-star review on Amazon. Here's how great it is. Don't forget to like and subscribe and SMASH that bell icon. Just smash the absolute shit out of it because I am deathly afraid you will not see my videos because they're crap and won't be promoted by The Algorithm (tm). [shitty outro music and graphics]
In a world filled with so much fraud that people shy away from the truth and even get angry at those who speak the truth, you are a beacon of authenticity. Thank you for what you have contributed to many DIY'ers projects and lives. Many of us have gone from being afraid of going anywhere near these sorts of projects, to building solar + battery systems with attached inverters that we use to power our homes during peak hours, or an emergency or for the best reason of them all.. BECAUSE WE CAN! (Thx to you!)
I love your comment about how the suppliers didn't want to sponsor you because they wanted to be the only ones in the video. It's really impossible to compare unless you have more than one .... LOL!!
You make me laugh, and I learned so much I have seen this video before but now I understand more of it. It's been a year that I have been watching you thank you so much for all your hard work!!!
Thanks for not having cheesy openings and closings to your videos. Right to the point. 👍🏻
I agree I get so tired of people begging for a like and subscribe and share and comment. I swear sometimes the begging is 1/3 of the video lol
Henry C Cheesy openings cheesy smiles I called that the UA-cam smile 😬 and I did 👍🏾 your comment. He does good work and is very clean with his presentation I’m sure his acquaintances are proud of him. 🙏🏻🙏🏽🙏🏿
I agree...the whole like subscribe lets get started...who needs that
couldn't agree more...
Agreed. This dude gets right to it and doesn't edit like an asshole youtuber. Thanks for this stuff.
Your speaking Greek to me now. But watching your videos I'm sure will learn me. Thank you. You have earned my trust and respect in a short period of time
Thank you for your "out of pocket" review. Glad you didn't cave to the single unit comparison. Honesty & Integrity are hard to find these days. Kudos to ya :)
THIS IS WHAT SOCIETY NEEDS!!......how many times do you start asking questions in shops about their products and they usually don't have a clue!!......and after a while you just stop going too the shops........just go online.......yeah.......this person is making life fairer for the masses.....some times 10 minutes of specialist knowledge that just works well!!.....is more powerful than 7 years of UNIVERSITY......unrelated training....
Will, your content is absolutely top notch. Please keep doing this for as long as you can, you have helped so many people!
Dude. You have just raised the bar by sticking your honest reviews. Thank you
When you are in your Solar Groove there is no one who does it better. Great video!!!
Very fair comparative review. Shame on the manufacturers for not having enough confidence in their equipment to sponsor your analysis. Thank you for the information. This is an excellent channel.
True. Will explains things in a way that is clear, concise for someone such as I who has had absolutely no idea of how to contemplate a beginning to solar power. I am ready to jump in now, get off grid with my "new" used motorhome, and see this beautiful country....
the whole point is Will is independent - no bias, no back handers and if YUOU want to help - go fund his patreon page (Like I did)
The manufacturers missed a real opportunity for product improvement advice.
Thanks for reaffirming my decision to purchase your "favorite". Have been using mine at an off grid cabin for a couple of years now with no complaints.
Thank you, sir. I love the multiple product review. Don't let them change you. I feel like it shows that they don't have enough confidence in their product to be able to have it compared to others. Regardless, you can tell that you really know your stuff. Conveyed by the fact that you're not having to read off of notes, while still being able to relay the information concisely. So much knowledge in one video. Thanks!
Amazing! You stated and displayed your test Lab. You test and compared all charge controllers to each other. You stated which charge controllers should be used based on battery chemistry. You mentioned how to achieve optimal value for your dollar. Excellent, Will. Thank you. And you did all that in twenty minutes!
Probably needed to mention that the cheap mppt will last 2 weeks and not 20 years. Will you also didnt mention which unit causes the most RFI.
Simple: I see objective reviewing, I subscribe. and when they stay that way I stay subscribed.
Bobcat...Everyone should challenge their own assumptions on a daily basis. To do otherwise is to give rise to stagnation and complacency. Do you really believe you can discern who is unbiased based upon the content of a UA-cam video? If only deciphering the human condition were that easy. Shake that cloak of denial once in awhile just to be on the safe side.
Will! I have loved everything you do for years now, but I was a bit shocked at 19:29 “a lady that does need to program it ever in her life” - of all the vanlife couples I know, the ladies are all the ones who have planned and designed and programmed their electrical system!!
Wow Will, you are a diamond in the YT world! EXACTLY what I needed to fill in the gaps of my base. You're a natural teacher, very enthusiastic, and thanks for no crappy music! 5 stars! Buying from your website for all my solar stuff!
Please, I want to know 40A solar controller and how mean 100w solar panel size it.
Nancy could please give me the name of the website...Thank you...highly agreed with you
I have 8 12v 100w panels 4 in series to a $15 controller to a Led acid bank and 4 in series to a $15 controller to a 100Ah LiFePO4 battery. 5 Months now without any problems. :)
I have had 10 75watt 12v panels daisychained to make 5 - 24volt output panel disharge for over 20 years, and used a cheap 12v/24v PWM controller for most of its life, till I got gifted a 50 Amp RV Power mppt controller and could finally clock amp output on cloudless sunny days at mid day and found my system was making 22 amps so may have been exceeding its capacity (prolly 20 amps).
The 50 amp fragged itself so I am considering pushing the panels thru 2 cheap PWMs to lessen the load on each.
They all charge fine, in the long run but it's not worth the risk of using them on top of expensive batteries.
Man, you have the most comprehensive channel on solar.
You saved me from getting some ultra expensive charge controller that I don't need. Trying to put together my 1st solar system here. Thanks.
You alone sir are the sole reason i understand solar enough to not fear it.
Thank you, you give me everything i need to build my offgrid home
Bumped into your videos. Am a mechatronic Engineer Kenya. That is so generous of you. Your videos are educative. Keep it up.
My gawd dude, this video is absolutely amazing! From the moment I clicked and started watching, listening to you talk and explain the setup and everything, I could just tell that we were gearing up for a really great, really honest, and very thorough review. I'm now 6 minutes in, and just couldn't resist pausing for a second and giving you some praise man! I wish all guides on youtube could be this educated and well put together. I've been building some 18650 battery packs lately and I'm starting to dive into the realm of solar charging; I'm definitely going to subscribe and will be looking your way for any future Solar needs :) Thanks so much!!
I love how you're just 100% honest and direct to the point. It sounds like these manufacturers are just scummy people who only want to sell a product, and not provide a good experience for the end user.
That's almost every manufacturer now sadly. Their goal is to sell you a product that lasts only a year or two and make you buy it again.
One of the best solar energy components video I have ever seen. Clear pricing and objective data
I bought the Tracer bn40 a few years ago....Still going strong and pleased I made a good decision and purchase.
Outstanding Presentation. Lighting=Excellent. Sound=Excellent. Camera angles=Exclellent. Scripting=Excellent. Pacing=Excellent. Content=Excellent. Also 5 stars for avoiding graphic/video effects that only demonstrate an inflated ego and add nothing to the content. Many video presenters could [should] learn a lot from your work. Well Done, Sir!
Anal? Stop commenting about sound, scripting and content etc. no one cares and it just introduces a psychological anxiety and paranoia of being scrutinised. You’re not the only one that does this and I hope it doesn’t catch on. It’s cringe, You are not a judge or a critic, stop pretending to be.
I got the victron one because its small and it works in harmony with my victron shunt. also it doesnt get hot. mine is inside my tongue box right next to my 200Ah lithium battery with a 200w solar panel going to it and its just chilling out at ambient temps throughout the day. Also the small was very important because i have teardrop and space is very valuable so anywhere i can cut down on size is pretty great. i also like to be able to see the charge stats while driving down the road via Bluetooth.
You are providing a wonderful service, at the appropriate technical level. I love how you are up front, and very transparent when it comes to equipment! I also like the fact that you don’t do any goofy things, no cheesy music, lab coat or fast talk. Young man, you will go far in this world!!! I am new to the Airstream world and looking at adding solar to it. Keep up the great work! I am slowly watching your videos, and already have the book! Thanks... Rob C.
The EP ever 4210, it's a affordable controller and very good quality
I had mine for 5 years and never had trouble, works like a clock
I never go for expensive staff, there is no need to pay for a brand and it's cheaper to replace.
Clearly some of the brands are nothing but the same generic thing rebranded.
Ridiculously brilliant. How many years have I looked for these answers!! Thank you! Just bought your book.
An updated version of this video would be awesome!!
Thanks for including the "2 Charge Controllers Myth Disproven" @ 11:38.
NO, NO and no! Nothing was "disproven". For goodness sake people separate your myth's from reality!
THESE particular charge controller's results are. To and from, these particular models, under this particular conditions! DO NOT extrapolate information based on air &wind!
I just found your channel.. I'm an old technician, and I think you do a great job.. keep up the good work, brother..
Ok I'm that old lady that never needs to program anything. Lol thank you so much for the info, I'm completely lost on all this and you have cleared up a few things for me. New sub.again ty
I think you are the best youtuber that does solar power related videos. Every video of yours is so well spoken any newbie can understand! Thank you!
Rich Solar owes you a commission. Because of this test video i bought a Rich Solar 20 am controller. It's been three days and im very happy with it. Thanks again, and greetings from sunny Jamaica.
Update: 20 amp Rich Solar charge controller is doing very well. I am up grading with more panels so i need a bigger charge controller and i have decided to buy a 40amp Rich Solar this time and connect both together.
Update: I got the 40 amp Rich Solar controller and running both the 20 and the 40 charging the same Power Queen LiFeP04 battery. I am very pleased with their performance.
Damn - I just ordered a Renogy Rover (not delivered yet) and, like you, I believe in using the largest gauge wires possible which means 10 GA to the panels (10A max current) and 8 GA to the battery bank (40A max). I was a bit concerned about the wire terminals and now that I've seen your video I realize the Rich Solar controller is a much better choice. I'm happy Amazon has such a good return policy...
Thanks for the review - you've just saved me some grief!
As handybob stated, thinner wires are a bad place to save money. Im gonna use #4 wiring for everything. Im considering using #2 wires from controller to battery bank. The shorter the wires are, the less resistance you will have, and you will want to keep your batteries as fully charged as possible at all times. Also, its important to keep positive and negative wires all the exact same length, or one wire will carry a higher load, especially when hooking the batteries together. I'm going to do this for my whole system., shortest wires possible, all the same length. I'm not sure if thats completely necessary but it makes sense to me so...
@@nicksimon4536 I'm running a pretty simple system - two SLA batteries with probably a max 5A working load though possibly a 40A charging current. The battery interconnects are 4 gauge while the system wiring is #8 to the controller and #10 to the distribution panel. I ended up using the EPEVER Tracer 60A MPPT controller which had no issues with the larger wiring.
I've been using Victron products for many years, they never let me down. Never had a problem with the connections. Over sizing wires is not necessary if you are careful about your connections. I have used some of the cheaper products you mentioned and found that they will fail after a year or two, I then moved to Victron and been happy with that choice for 10 years now. I am sure there are many great products for solar systems but it is always true that you get what you pay for! I do enjoy your videos, keep 'em coming. Thank you.
@Jon Phillips
Over sizing wiring at 12V still provides advantage over ‘the right sized’ wire for panel cables. The quality of crimp doesn’t make up for that advantage all else being equal.
More importantly to me is battery-to-inverter cabling. 2/0 VS 1/0, or 3/0 VS 1/0 at “full” inverter load adds a level of efficiency you can often feel with your hand by the temperature of the cable. A warm - or worse: hot - cable is clearly not at 100% of its potential efficiency. For example, a 1200W inverter running a shop vac: the advertised peak on the inverter I’m referring to is 2400W, or 200+ Amps at nominal 12V. The ‘correct’ sized cable would become warm to the touch after a period of running the shop vac. I replaced it with two gages larger and that doesn’t get warm ever.
I suppose I could look up the tables but I’m sure the correct wire was safe enough. However, safe isn’t enough; on a small system that lack of temperature rise in the cable spells “more efficient.”
Great video! One other very important test is the amount of RFI they put out. RF Hash that ruins emergency communication and Amateur radio reception. As well as Shortwave and standard broadcast AM. A simple test is to bring a portable AM radio into proximity with the equipment and note the amount of static that is generated from the device to the radio. An important factor when choosing a controller for communication setups. Thanks!
you are an expert!
I wish I would have upgraded to my mppt years ago. Makes a big difference here in Oregon.
One comment, one request, and one suggestion. Comment: Great job on all of your videos! No wasting time with intros, fast paced, edited, info packed, pleasant delivery, and more, as per all the other comments. Request: Compare real world performance of 4 x 100 watt panels in series versus parallel. Series connections good for producing power early and late in the day when voltage would otherwise be insufficient to begin charging versus the performance drawback of not being in parallel. Good to know best solution on sunny day, on an overcast day, and a day with intermittent clouds. Suggestion: You use the word "cheap" to mean both poor quality and low cost. Although not necessarily confusing if the listener pauses to weigh context, there is no other word but "cheap" to represent poor quality, so that is the proper term. The word "inexpensive" is best for low cost.
Good suggestions, thank you
It would be interesting to see these tests over time. To see how the MPPT vs PWM does with changing conditions / early & late day.
MPPT VS PWM make a very similar amount in peak sunlight, the difference is low light and early mornings.
You’re amazing. I learn so much in such a short time. Thanks for no BS and no music. Easy to listen.

My head is swirling right now with all the info. But I'll sort it all out. I'm doing a van build and will be putting about 300-400 watts on the roof. And probably 2 100ah agm batteries to start. Your videos are a wealth of info, thanks.
You care to do an update for 2022 ? Love your videos man !
Straight forward. Right to the point. No bla bla talk just to make long videos.
As a total newbie I have to say, you are amazing!
you are the boss man! I used to sweat out of frustration trying to learn these type of things in school. You make me learn, without the sweat and the frustration. Thanks alot man! Really appreciate it!
This is a great comparison video. It makes things clearer by having the other brands on hand while reviewing them. I'm a noob to solar so this was very helpful, thanks
Went camping last week with a couple of yellow top optima car batteries I hade laying around and a cheep mppt from Amazon and 200 watts of solar and it ran my 12v refrigerator /freezer all week, no problem, it was a fun project to put together and no running out of ice.
Best advice I seen.. Don't over buy for features you don't need. Put the savings in Batteries...
Glad u mentioned that multiple chargers won’t “fight” each other. I want to add a few panels to my RV. If I’m not at camp and mama wants to run the generator for the microwave or air conditioner, I wondered what would happen when the A/C powered kicks in but senses the power from the solar panels. Which one would win or take over?
YOU HAVE THE BEST VIDEOS ON THESE SUBJECTS. THANK YOU!!
I think its important to also remember this test is done on products over the course of only a couple days. Anything should output somewhat evenly out of the box. But how does it perform over an extended length of time? I've replaced a LOT of 6-18mo old renogy controllers for a number of different reasons in solar systems in campervans, but have never had to replace a Victron. How do the outputs vary in hot climates? Cold climates? Still a great test to start with!
I am using a Rich Solar 20amp in sunny Jamaica going 7-8 months now with no problems. Im planning on buying a second one soon.
I really appreciate you telling the truth and not what the manufacturers tell you to say. I love your videos. Very honest and informative. Thanks bro!
I’m from the UK and think your candidness is really great. As for the manufacturers wanting sole promotion tell them to get lost.
im in Aussie would like a video on setting up basic solar system with lithium 200 ah battery for a caravan ,just not sure what controller to use ,i just love your videos cheers
Use Victron!
The 100/20 reg he uses in the video is very small and most of things he complained about, are not an issue once you go to their bigger regulators.
And you can plug in a display via the ve port on the bottom of the reg, or even a GX color screen that will take multiple Victron products.
What solar array are you going to use?
I live in Australia in NQ.
You rock young brother, I actually learned a bunch from your videos, you give a very clear and simple instructions...
U really have it together !!!
I love the way you explain all the details, you are a great teacher, I'm glad I found your channel. Thanks William Orange county, ca.
I love the way you teach. You know your stuff and confident enough to not have to confuse people with to much technical jargon to show how smart you are well done !!!!!!!!!
I bought the Renogy Rover MPPT for a portable solar setup for ham radio. The Rover absolutely destroyed the ham bands with interference. Then I bought the Victron MPPT - it is radio silent. no issues using it while on the radio. That's why it cost more. Much better filtering.
Thanks for helping me to wade through solar controllers and amps, watts, volts, etc. I live in Haiti and depend heavily on solar power!
Well done! I appreciate your "assessment neutrality" based on specific uses.
Rich solar is looking better and better 👍
I didn't catch the name of your mppt solar charge controller. Great video for beginners thanks.

This test confirms my own results having used both PMW and MPPT controllers. I don't need to squeeze every single watt so I still use PMW often.
So what is the controller for? You begin way over a beginner' s head (me). And, how would I build or design a solar thing to work for my cabin from what you are talking about? Far too complicated, do I put all this is a wooden box under the panels ? What do I do with this moderate/advanced knowledge you give us, would seem to be good for a tech person, but what about us?
I think he means a beginner's guide to the controller component of the system. This guy is good if you're a beginner though, if recommend watching more of his videos and your cabin will be electrified in no time.
This is all beginners level, in fact very basic beginners level!
If you really feel the need to get deeper into the subject! I do advise to study a little bit more than a short YT video can provide! There's enough knowledge online! As well as on books! ;-)
In simple terms the controller allows solar panel output to run thru the controller and then output energy to the batteries. Assuming you have lead acid batteries or even liFePo you need to set the point at which the controller stops pushing power to the batteries OR....your lead acids will boil out the electrolyte and fail prematurely (past 27.5 v on a 24volt battery setup (the float limit), or 28. 5 v on a LiFePo setup or you can damage those depending on the battery). So it is a limiter to keep from destroying or harming your batteries.
This is a really nicely put together comparison. Great for people that want to get the basics and install their own solar.
GREAT JOB! It's easy to see that you are professional and very knowledgeable with a great style and energy. Also appreciated that you don't have a cheesy intro and are not into self-promotion just for ego sake. Nice job, I subbed right away. Great information that's well laid out and different testing methods are explained. A shame the manufacturers won't support your efforts but you tell of all their cheating and point out their shortcomings - not hard to see why they don't like you. But I sure do!! YOU ROCK!! Please keep them coming - I'm just learning!
I used the little/cheap charge controller to on a portable system with one panel and one battery and a timer to water a small, remote orchard in Idaho. It worked very well for that purpose.
Great explanation. I knew NOTHING about hooking up a solar system and now I'm doing my first setup on my caravan. Your videos have been very helpful.
Ive got the "small crappy one" on my boat. Works perfect on the 120watt panel charging the 130amp Carbon Lead house battery. You can even programme the output to run for different times from 1hr up to 24 hrs. I use my one to run a fuel polishing pump 4 hours per day while i'm away from the boat. Keeps the diesel nice and clean as well as keeping the house battery at optimal float voltage.
Quick summary, then "...and yeah, I'll talk to you guys later, bye."
Perfect outro, thanks for that. Any updates within the past year to any of these? I'd be curious to know. Also, I know it's only 1 compared to your current amount, but you've earned a sub with this and a couple past videos, thank you for the content and for satisfying my curious mind. I'm an electrician currently planning a setup for random things, not quite to live off-grid or anything but for other experiments/hobbies, but your content's much appreciated.
Man I'm sure glad I stumbled across your channel because you explain this electrical stuff in a way I can understand better than anyone I've ever seen. Not saying that others aren't good but you would be a great teacher. I'm going to install some panels this summer after my roof has been reroofed as soon as my roofers get to doing my roof. Soon anyway. I'm encouraged. I can start off doing this with the good stuff and still not break the bank. I'm happy.👍 I'll get your book as soon as I'm through posting this. I'll be in touch. Thanks man.
I’m just getting started setting up a support vehicle for my projects.
Since the vehicle (‘92 GMC Truck) will be outside and is a service vehicle, I’m planning on putting two large 250AH lead acid batteries in a large toolbox on the roof rack (fire proofed and insulated)
and connecting your favorite charge controller to them.
I’m planning on using one 250 watt solar panel on the toolbox, and possibly two inverters, behind the seat (one for just general 110 use in the cab, and the other wired into the automatic cold weather heater and engine block heater, coupled with an AGS switch for the dedicated onboard generator.
Just as a suggestion, you should think about creating a shopping list in Amazon for components that you recommend. It would make it easier for the your viewers to customized their own setup and be confident on getting their moneys worth. Thank you for sharing your knowledge.
Thank you for your integrity and not just going with one brand but buying them all to test for us! :D
That alone is reason to sub! Thanks for the vid! :D
I have one remaining question - What is the fascination with these screw-pinch connectors among manufacturers? I'd prefer good old screw-type barrier strips with crimped lugs on the wires.
liability - can get zapped from copper lugs
Great info. Very good review. Just got my EPEVER 40a controller w/ MT 50 remote from Amazon. Going to hook it up this weekend at my cabin. Replacing a Renogy 20A PWM
Hey can I ask you something??? How’s that new epever working out for you???I’ve been looking at them,,,,I bought a 60 amp Renorgy commander a couple years ago and it only last about a year and then it went out on me and Renorgy wouldn’t make it right,,,they really didn’t care,,,I paid over $500 for it,,,,big rip off,,, I’m thinking about buying a new charge controller but I don’t want to buy a piece a junk,,,would you say your new 40 amp here is worth it?????
william foreman it’s been going great for the past year but plan to update soon to an Outback Flexmax 80 soon just because my system is growing
Thank you, I've been trying to figure out what type of charge controller I need for my lead acid battery bank. You've answered my questions. I have 4 deep cycle RV batteries and 4 AGM batteries [which were given to me from a friend]. So my plan was to charge each pair individually and then move to the next. With the purpose of being able to re-charge my phone, portable radios and various batteries around the shop, plus being able to have DC lighting around the house. I have some cheap and inefficient panels hooked up. I have a portable generator hooked up to my panel - but if I ever run out of gas, I want to have some means of charging.
But in the end I plan to get a EcoFlow Delta and portable solar panels - I'm going with the KISS method. Maybe I'll give my battery system to someone on a limited budget and let them follow your recommendations.
You do a good job explaining some very complicated concepts [for my knowledge background] thank you for the work you put into this subject.
Your channel is great! I’m building an off-grid workshop that I was going to “do something simple”… a fridge + a few lights. You’ve given me the confidence to do something much better and I know I’m buying quality components.
So the whole selling point that MPPT will charge 30% faster is not true? They charge,pretty much the same as pwm?
NO, No, no! They both have their perfect spot for existence!
Your very incorrect "30%" statement is as erroneous, as the conclusion regarding this test!
Please do not assume things based on short and obviously incomplete information!
This particular test was designed, by chance it seems, with the perfect conditions for a PWM controller! That's it! Nothing more, nothing less!
Exactly the same way, the test that showed you the "30%", was designed to show that result! If there was intention on the design or not, that's whole different ball game! Most of this tests are made by amateurs, with a lot of chance involved. Instead of a lot of knowledge! This video is no different! Seems innocent enough!
Well, than there are the pro's who really want to show you a specific result. And cook the test parameters to show you exactly that! ;-)
I had hoped to see a 30% increase(I always hear about it), of the MPPT controllers over the PMW controllers ... but the increase was very negligible. Is this because the panels are close to 12 volt output?
This was tested on single solar panel use...mppt benefits come in to there own for multi solar panels using parallel and series or both linked. Also some of the cheaper models don't show an accurate reading if you put a reader straight to your battery.
Panel voltage drops with temperature, that’s the only logical explanation. Panels are rated at 25 digger Celsius.
Gotta be something like that.
Ye we did learn something,well I did,thank you Will.Yes I am an Electrician and I find you videos both entertaining and educational
I have a portable foldable 120w setup for my motorbike and even though it came with a PWM, went out and bought a MPPT after viewing a few videos. Now that I have seen this video I feel even better about my setup.
Made the mistake of going with Renogy everything building an off grid tiny house. Once I got the house in place in rural Kentucky my mistakes became apparent. Renogy's tech support is non-existent. You have to talk to a call center and trust that person with no technical knowledge to translate your question to tech support and then translate their answer back to you which takes weeks. Your videos have saved me. The only thing Renogy ever tells me is that I need to buy another piece of equipment. I'm currently running two 500 W solar arrays through 40 amp controllers which are run in parallel to my battery bank. I switched from a 3000/6000 modified sine wave inverter to two 1,000 w pure sine wave inverters. One runs constantly for my refrigeration the other I only turn on when I need to run a small appliance. Renogy actually told me that none of their controllers could be run in parallel except their most expensive one which was complete BS. For those times when it rains for days I have a smart charger which I run off the 3000 watt inverter which is connected to my diesel truck. Thank you for the education.
I have learned one thing, it is very confusing. When I get ready to build my system I'll just come to Nevada to have you do it
If he gave solar classes at school, I'd pay to go to his classes. Another great video, thank you.
This is the exact review I have been looking for, thank you SO MUCH!!
Thanks Will, i lover your videos. I am currently in school to be an Electrician at Los Angeles Trade Tech College and our professor uses your video for us to learn about charge controllers. Thank you
I have that little one, I use it for a solar panel to keep a box truck batteries charged. one panel 100w, it works great for my basic use. Thanks for this great video
I just saw your intro from Jamie at the 2019 build. Thank you for your videos. You've made the hardest decisions easy for all of us.
