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 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.

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. 👍🏻

The beginning got me hooked instantly. (No intro music. No BS.)

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!

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.

Dude. You have just raised the bar by sticking your honest reviews. Thank you

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'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 KZfaq. You provide the most informative videos of all KZfaqrs. Thank you for making it easy to understand and having the integrity to provide information that I strongly feel can be trusted.

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 :)

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!

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!

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.

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!!

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.

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!!!

Simple: I see objective reviewing, I subscribe. and when they stay that way I stay subscribed.

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!

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!)

YOU HAVE THE BEST VIDEOS ON THESE SUBJECTS. THANK YOU!!

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.

Ridiculously brilliant. How many years have I looked for these answers!! Thank you! Just bought your book.

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!

One of the best solar energy components video I have ever seen. Clear pricing and objective data

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 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!

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.

This is the exact review I have been looking for, thank you SO MUCH!!

You’re amazing. I learn so much in such a short time. Thanks for no BS and no music. Easy to listen.

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.

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!

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

As a total newbie I have to say, you are amazing!

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.

Excellent!! Went through multiple videos and still didn't learn what I needed till came to your channel. Learned so much! Thank you!

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 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

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.

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.

You rock young brother, I actually learned a bunch from your videos, you give a very clear and simple instructions...

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!

One of the best vids every. Your best video I have seen yet. Keep it up! Thanks!

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 just found your channel.. I'm an old technician, and I think you do a great job.. keep up the good work, brother..

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!!!

Have you been learning this your whole life ? Your very knowledgeable. Thank you for your content !

This is a really nicely put together comparison. Great for people that want to get the basics and install their own solar.

As always, I learn something. Thank you. 🤓

I so enjoy your videos! You explain so clearly along with your visuals. So glad I found your channel! You Rock!👍😃

I really appreciate your videos. They are very educational. You're the only channel I've ever subscribed to because I hate when other channels tell you to subscribe some of them just sounds like they're begging and spend like 5 min telling you to sub or like the video.

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

Informative video and congratulations on passing 60k subs.

Bumped into your videos. Am a mechatronic Engineer Kenya. That is so generous of you. Your videos are educative. Keep it up.

Absolutely great freaking job, Thanks for taking your time for sharing your expertise and teaching us tubers with your knowledge. And Holly crap I just watched a few more of you videos(hits) and you got it going on. 👍Thanks again, Sigs~Michigander✌🏻

Well done! I appreciate your "assessment neutrality" based on specific uses.

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.

Can't believe Im binging on solar diy vids. These videos are quality, can't say enough about them

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

Thanks for including the "2 Charge Controllers Myth Disproven" @ 11:38.

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 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!!!

I like your videos, honest, thrustworthy and qualified know-how. Thank you!

Man, you have the most comprehensive channel on solar.

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

Your videos are great Will! I have learned so much and now I am going to build a new system.

Very helpful video! Covered all the points I was wondering about including the size and quality of the terminals! Thanks very much for your help!

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.

Thanks Will. I always get the right information from you.

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 💖

You videos are superb and much impressed by you knowledge and ability to make it easy for non electricians to understand. Very much appreciated as trying to quickly get up to speed on solar.

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.

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!

This is a great video. I live on a narrowboat on the UK canal network and I'm in the process of getting my head around what kit to use for my solar install. This video has really cleared up a lot of questions I had about solar controllers. Many thanks.

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. :)

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.

Great vid Will, thanx for spending some of your own money to help explain this stuff.

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. -Adam The New Woodworker

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!!!

Wow, just answered every damn question i could possibly ask..thanks for sharing

As a newbie trying to choose a charge controller this video was on point! Subbed!

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.

You're such a huge help with my very first solar setup! Thank you,I thank you Subscribed!

You’re so knowledgeable, Will Prowse!

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

Incredible comparison! So detailed! Many thanks for your dedication and enthusiasm!👌

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 👍

This video is so informative 💯 great test!

You are very knowledgeable about this subject. Thanks for sharing. I've subscribed and learning.

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 like the way you think things through and convey them. Good video.

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.

Well done... Good job William, Thanks...

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.

Very informative video , just found you on youtube , I'll be following from now on. Thank you very much for sharing !!
