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.
Corrections:
16:14 I switched the two numbers. I said the right numbers, but I didn't list them properly.

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
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.
You are, young man, one of the most motivated and enthusiastic individuals in the realm. You will go far, pilgrim!
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.
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.
Will, your content is absolutely top notch. Please keep doing this for as long as you can, you have helped so many people!
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!
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]
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 :)
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 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.
Dude. You have just raised the bar by sticking your honest reviews. Thank you
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.
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
AWESOME VIDEO...Came in knowing NOTHING...left with a rock solid decision on the right charge controller for my project. Will, I really appreciate your hard work and dedication to solar testing and education. You make it look so easy and it gives me a lot of confidence. THANK YOU!
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.
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 !!!!!!!!!
You have been the biggest help! I've been wading through this swamp of solar electric overload and you have cleared up so many things. I'm throwing a 12v battery system in my off road truck for long distance camping.
When you are in your Solar Groove there is no one who does it better. Great video!!!
One of the best solar energy components video I have ever seen. Clear pricing and objective data
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!)
WELL DONE! Your videos are absolutely fantastic! I have been wanting solar since I was 14. I am 68 now. We bought a system for our home in Sydney ten years. We are now in Tasmania on a small property. The Tas' house already had solar when we moved in. I am building solar systems for sheds around the place and your videos have been a HUGE help! THANK YOU!
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!!
As a total newbie I have to say, you are amazing!
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.
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!
Loved the detailed walkthrough of capabilities.
The real gem is your closeout: sharing the appropriate application for each unit was spectacular. Each unit is valuable for its specific application.
Thank you so much!!
Keep the vids coming, thank you for educating me and the rest of the planet.
YOU HAVE THE BEST VIDEOS ON THESE SUBJECTS. THANK YOU!!
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.
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.
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.
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.
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!
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!
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
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
Ridiculously brilliant. How many years have I looked for these answers!! Thank you! Just bought your book.
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.
You’re amazing. I learn so much in such a short time. Thanks for no BS and no music. Easy to listen.
Lll

I just found your channel.. I'm an old technician, and I think you do a great job.. keep up the good work, brother..
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!!!
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.
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!
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
I love your honest reviews. It makes it easier to decide what to buy for my future system. I also really like the fact that you give enough information that it's easy to follow.
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.
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.
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!
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!!
This is the exact review I have been looking for, thank you SO MUCH!!
Well done! I appreciate your "assessment neutrality" based on specific uses.
Great video, Will. I went with the Weize version of the Rich MPPT controller. It has the more rugged power connectors and programmed up fine for my two series connected Newpowa 100 watt panels into my six gel cell house bank on my cruising sailboat. Same price point. Fire and forget, running flawlessly.
Bumped into your videos. Am a mechatronic Engineer Kenya. That is so generous of you. Your videos are educative. Keep it up.
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.
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!
Thank you very much ! 💖
I'm from SriLanka.
Your video helped me a lot to understand that the power output difference between a PWM and an MPPT is around 3 % .
I'm on a low budget so your channel is the only place in the entire youtube where I could find the solutions with realtime experimets 💖
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
You rock young brother, I actually learned a bunch from your videos, you give a very clear and simple instructions...
Incase you guys find this interesting, i had not watched this particular video, but went camping this weekend, sleeping in my jeep, and had no electric hookup so I dialled up amazon picked up a 100w panel and the 15 buck re-branded PWM controller. Ran the lights and a small electric chiller box. I thought the controler was going to be garbage, but it worked really well, was getting 50w out of the panel (flat on the roof, not angled correctly to the sun) and despite the batt draining to 11.6v overnight, charged back up again to 12.6v the first day and 12.3v the second day (more clouds) and when I packed it all up the car started fine. I almost bought the Victron 75/10 but I decided to keep it budget for now and I am so glad I did as Wills video above proves what I experienced that the 15 buck controller really does the job well! The price difference is not worth it if jeep/car camping with short cable lengths, I may get another 100w panel with the money I saved from the Victron controller!
Just gotta say I did pretty much the same thing, but about 5-6 trips out that cheapo went blank and won't come back- why I'm watching Will now.
Excellent!! Went through multiple videos and still didn't learn what I needed till came to your channel. Learned so much! Thank you!
Can't believe Im binging on solar diy vids. These videos are quality, can't say enough about them
This is a really nicely put together comparison. Great for people that want to get the basics and install their own solar.
Thanks for helping me to wade through solar controllers and amps, watts, volts, etc. I live in Haiti and depend heavily on solar power!
I never thought of hooking two controllers up to the same battery bank. Thank you!! This saves me some dough.
Will, you are amazing ! Trying to figure this stuff out for our off-grid (we do have propane) home sitting at 10,000 ft. in CO This was a great, unbiased review and even understood by a caveman like me.. Thank you.
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 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.
Amazing you just answered my question that I’ve been hunting for.
The one about using two control units on one battery bank. And the bit about them fighting each other. Thank you so much!!!
I bought the Tracer bn40 a few years ago....Still going strong and pleased I made a good decision and purchase.
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
Man, you have the most comprehensive channel on solar.
This is the type of comparison videos i need to see. With you explaining the differences in the PWM and MPPT controllers and their advantages and disadvantages help the less informed person such as myself make good choices. Im learning tho! Thank you Will for these type videos 👍
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.
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.
Well I am just astounded by your knowledge and I am so grateful to find your channel. I’ve been been watching your videos for a few hours now and I’m just soaking in the information. Thank you so much for your channel and for all of this valuable information for people like me! I’m getting ready to buy land out in Arizona and build off grid compounds to rent out but I will be living off grid in a travel trailer when I first arrive so assembling my first DIY solar kit will be crucial. I’m so overwhelmed with the information lol.

Have you been learning this your whole life ? Your very knowledgeable. Thank you for your content !
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
As always, I learn something. Thank you. 🤓
You, my good lady, have somehow managed to state the theme of my life and my main competitive advantage..."As always, I learn something." You keep learning and widening the gap between yourself and the zombie mouth breathers the world is full of.
One of the things that need to be emphasized (something you alluded to at the end of the video) is if you are planning to have a system that can be expanded, go with the charge controller with a higher amp rating. Watts is simply amps x volts so more amps (assuming same volts) will allow you to push more power (watts). Other than that, excellent video.
Or use one MPPT controller per panel for better efficiency
Bgg tut
I did indeed learn a lot from this vid! I only wish that I’d watched it before my most recent pwm charge controller purchase. Live and learn as they say!
Informative video and congratulations on passing 60k subs.
I'mpleased that I found this video, really helpfull for me.
I very much like the 'no-nonsense-stick to the essentials' style of presentation.
Thank you.
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.
I'm living off grid on a narrow boat and I'm looking to get ready for my first winter on board. Your videos are really helpful. Still need to work out the best system though for my boat, for the fridge, lighting, TV and playstation, phone/laptop charging and a few other bits on a very tight budget lol.
Keep up the good work
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.
You’re so knowledgeable, Will Prowse!
I just started investigating solar for an RV. What I have read is that partial shading of even 1 cell will significantly drop out from the panel. When panels are linked in series, the controller will adjust to the lowest output but in parallel, the MPPT controllers will output the maximum voltage from each panel for a larger total output to the batteries. I would love to see this confirmed on your setup by comparing series vs parallel with PWM or MPPT. Thank you for such informative videos.
An updated version of this video would be awesome!!
Rich solar is looking better and better 👍
As a newbie trying to choose a charge controller this video was on point! Subbed!
Outstanding video...just what i needed to advance my charging system.. I had no idea that there was so much of a difference and variety of charge controls out there and what they can do. cool man
I’m from the UK and think your candidness is really great. As for the manufacturers wanting sole promotion tell them to get lost.
Hi from Aus Will, great video as always! Those Epever Tracer's are a great little MPPT, Adam Welch got me onto them with his videos about a year ago and they work really well. Recently got myself some second hand cheap 2 year old 200w panels so going to need an upgrade and it looks like the Tracer BN series will fit perfectly, thanks for the recommendation.
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!
Hey Will. Love Love your videos. I am switching my travel trailer from FLA batteries to LifePo4. Your videos are very detailed and your tear downs are very helpful. I am going with the 100ah SOK's, two of them. I will also be upgrading my current solar controller on my trailer. Thank you again!!!
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....
