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?
Henry C Cheesy openings cheesy smiles I called that the RUclips 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 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.
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.
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 :)
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, 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!
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!
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 RUclips 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.
Is it correct to assume the Rich Solar flavor of the Renogy uses the same BT-1 bluetooth interface and the same "Renogy BT" android app for config and monitoring?
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!!
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.
So, when it is all said and done, all of the MPPT perform pretty much the same. And comparing a $200 40a charge controller to a 20A is pretty unfair. Look at the Renogy Rover 40a. it has larger wire connectors and a dedicated Lithium program.
In all honesty, although there's several design faults on the test! I believe it's pretty fair for a one guy, out of his pocket, show! ;-) With this said it's obvious these particular test conditions make the dirty cheap PWM stand out, way ahead of the competition! With a ROI that's sounds unbeatable! Because in fact the entire test conditions and limits are perfect for it! In the same line, the other competitors didn't had a chance to shine in their own departments. Either by functions or possibilities! There's still validity on all this. As a show case. Determining that in this particular conditions the PWM can indeed be a valid choice! What could be worth mention is that beyond this perfect PWM conditions. Price aside, it would probably be the worst possible choice! LOL 😂
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.
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.
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....
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 RUclips. You provide the most informative videos of all RUclipsrs. 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, 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.
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 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.
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✌🏻
Hey Will, nice review... I’m interested in your thoughts on this new? unit from Renogy. DCC30S 12V 30A DUAL INPUT DC-DC ON-BOARD BATTERY CHARGER WITH MPPT
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.
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
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.
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?
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.
I have just ordered a 40a Epever like the one on the left. Here in Australia, there is cheap 💩 or massively pricey 💩 The Epever was a decent quality / price compromise for me
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!
Hey mate I hope you can answer this for me even though you kind of already have. I'm considering connecting a permanent panel to my vans roof that'll always be connected to the battery by its own charge controller. I also mainly want to use my portable panels to chase the sun, from what you've shown here quickly is that if they both run off of there own charge controllers and are both connected at the same time to the battery the battery will take regulated input from both panels meaning both panel set ups watt ratings will be joined and not fight each other, cancel out one another or cause damage to the battery? Say I have 100-150watts permanent on roof and 250-300 portable, completely different brands ect I'll still get a conjoined 400+watts from them in perfect conditions?
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!
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.
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!)
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.
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!
Important is to understand how to set the controllers correctly, which eliminates batteries to overheat and cause kill our costful inverters, most controllers need to be adjusted upon the battery capacity,
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!
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!
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.
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.
I'm glad now that I had bought the EPEver Tracer 2210an last year. I didn't know about the MT50 controller/display so I just ordered it. I don't need it for my AGM batteries but I need the MT50 in order to do Lithium Iron Phosphate batteries in the future.
This is my first shot at one of your milk create solar generator. I have a Giandel 1200 inverter with a built-in 20A charge controller. Would that charge controller be ok or should I invest in a different controller? Thanks for the great videos. They are a great help.
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
Hi. Great video. I am still struggling with whether I need a MPPT specifically designed for my blue carbon LifePo4 batteries. 4 in parallel for 800ah. I have 1500 watts of solar on my boat. Or if I can use any MPPT?
I have a 40amp Epever and can't seem to find a way to program it to properly lifepo4 settings without a PC computer. Is this possible? Or, which controller should I get (even if I must go to 50-60 amp controller)? I don't want to program it from a phone or computer.
16:14 Connecting two panels in series to a PWM controller. Great idea! I was just wondering if that would work. Besides that and a few percent efficiency in charging, is there any other advantage an MPPT has over PWM for a small system? Thanks for the great videos, I've watched a bunch today. Oh do you have a link to the 24v PWM build?
PWM best conditions are among others. Similar voltage in and out. The further away, one get from this, the bigger advantage a MMPT have on a given system! Example: - 12V nominal panel(s) to a 12V nominal battery, perfect condition for PWM! - 24V nominal panel(s) to a 24V nominal battery, still perfect for PWM Following similar example. 24v (36V or 48V...) panel to 12V battery, PWM not good at all! An MPPT would be way better on this condition! ;-) In other words if everything is perfectly matched the PWM perform quite decently , in fact the best ROI possible! (Return Of Investment). On the other hand step away from these perfect conditions. With dissimilar panels, voltages, partial shading, etc. that's MPPT territory! ;-) For a simple 12V or 24V system, it's a direct and simple hook up! Even the cheapest PWM controller shown here. Will automatically switch from 12 to 24V. Cheap simple and easy! ;-)
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
What if your running 800 Watts of PV? You need 60A. A comparision of that level would be interesting because there is less incentive to make them cheap at that price point. I would like to see a nice mid range system test although the cheap end of the spectrum was also interesting.
What is the max power rating of each single panel? My research would suggest MPPT is more advantageous when there is more voltage, so a single panel test would not demonstrate the differences.. eg, if you measured each with 2 panels connected, parallel and series, the results would be even more interesting. Good review
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.
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 know you can't read all the comments so hopefully some people would like this one so that it will get your attention but if there's any way you could do a schematics or a person that was scalable kind of like this trailer but for RV maybe the concept that you have right there will work but a lot of my RV appliances run off 12 volt I'd be willing to by the battleborn batteries as well just would like to do it on myself and don't know what inverters would be best thanks
Great video Will, do you think the MPPTs with two 100w panels in series will out produce the PWM with two 100w panels in parallel? I'd love to see data over time to get some realistic use type stats. Again great video!
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.
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
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!
Can you tell me why my Renogy controller only charges one-tenth of a volt more than the battery has. No matter what the battery voltage is. This solar power is confusing. Thank you. Hank
wouldn't be surprised if they got McDonald's put it in the kids pack meals as a toy lol hey kids try out getting into solar and save money on free power
I laughed too. Even more so when I realized this was the unit I am considering. But then, I'm 'only' trying to re-charge a small sealed lead acid battery to power a trail camera.
@@ME-kq4wp - I have several of those. In spite of no failures, really cheap prices, easy usage, etc. I do advise to get a slightly better PWM! Cost wise they're unbeatable, but as mentioned having a temp sensor can be useful in some applications! Cheers
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.
that cheep $3 one I have had one of them for the last year, no problems before that an even cheaper one my lead acid battery where cheep as chips 6 yr back from eBay infact they were the cheapest on eBay at the time + still working ok
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?????

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?
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 RUclips 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 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 😂
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.
You are, young man, one of the most motivated and enthusiastic individuals in the realm. You will go far, pilgrim!
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 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 :)
Dude. You have just raised the bar by sticking your honest reviews. Thank you
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, 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!
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
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 RUclips 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.
When you are in your Solar Groove there is no one who does it better. Great video!!!
The companies don't like your videos because you give honest reviews. That's probably why you have nearly 900,000 subscribers.
Is it correct to assume the Rich Solar flavor of the Renogy uses the same BT-1 bluetooth interface and the same "Renogy BT" android app for config and monitoring?
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!!
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.
So, when it is all said and done, all of the MPPT perform pretty much the same. And comparing a $200 40a charge controller to a 20A is pretty unfair. Look at the Renogy Rover 40a. it has larger wire connectors and a dedicated Lithium program.
In all honesty, although there's several design faults on the test! I believe it's pretty fair for a one guy, out of his pocket, show! ;-)
With this said it's obvious these particular test conditions make the dirty cheap PWM stand out, way ahead of the competition! With a ROI that's sounds unbeatable! Because in fact the entire test conditions and limits are perfect for it!
In the same line, the other competitors didn't had a chance to shine in their own departments. Either by functions or possibilities!
There's still validity on all this. As a show case. Determining that in this particular conditions the PWM can indeed be a valid choice!
What could be worth mention is that beyond this perfect PWM conditions. Price aside, it would probably be the worst possible choice! LOL 😂
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.

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.
YOU HAVE THE BEST VIDEOS ON THESE SUBJECTS. THANK YOU!!
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.
What solar charge controller would you recommend?
Will Prowse: Yes
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 RUclips. You provide the most informative videos of all RUclipsrs. 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
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.
Great vid Will, thanx for spending some of your own money to help explain this stuff.
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.
This may seem a silly question, but can the alumin(i)um one electrocute you by touching it?
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.
This is the exact review I have been looking for, thank you SO MUCH!!
I just found your channel.. I'm an old technician, and I think you do a great job.. keep up the good work, brother..
Well done! I appreciate your "assessment neutrality" based on specific uses.
Absolutely great freaking job,

Hey Will, nice review... I’m interested in your thoughts on this new? unit from Renogy.
DCC30S 12V 30A DUAL INPUT DC-DC ON-BOARD BATTERY CHARGER WITH MPPT
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.
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
One of the best solar energy components video I have ever seen. Clear pricing and objective data
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.
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 are very knowledgeable about this subject. Thanks for sharing. I've subscribed and learning.
Will, Are anyof these Diversion capable? I want To divert my power to the grid when the battery's are full.
Thanks man keep it up!
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.
I have just ordered a 40a Epever like the one on the left. Here in Australia, there is cheap 💩 or massively pricey 💩
The Epever was a decent quality / price compromise for me
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!
Some lady who doesn't have to program anything ever! 🤣 You're killing me!
Yes! 🤣 🤣 🤣
Thank you!
Hey mate I hope you can answer this for me even though you kind of already have.
I'm considering connecting a permanent panel to my vans roof that'll always be connected to the battery by its own charge controller.
I also mainly want to use my portable panels to chase the sun, from what you've shown here quickly is that if they both run off of there own charge controllers and are both connected at the same time to the battery the battery will take regulated input from both panels meaning both panel set ups watt ratings will be joined and not fight each other, cancel out one another or cause damage to the battery?
Say I have 100-150watts permanent on roof and 250-300 portable, completely different brands ect I'll still get a conjoined 400+watts from them in perfect conditions?
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've got the cheap McDonald's toy one, wondering if I can get the data logged on my computer somehow.
No data logging on that one. ;-)
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.

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

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.
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 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!
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.
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!
Important is to understand how to set the controllers correctly, which eliminates batteries to overheat and cause kill our costful inverters, most controllers need to be adjusted upon the battery capacity,
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.
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!
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.
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.
I'm glad now that I had bought the EPEver Tracer 2210an last year. I didn't know about the MT50 controller/display so I just ordered it. I don't need it for my AGM batteries but I need the MT50 in order to do Lithium Iron Phosphate batteries in the future.
This is my first shot at one of your milk create solar generator. I have a Giandel 1200 inverter with a built-in 20A charge controller. Would that charge controller be ok or should I invest in a different controller? Thanks for the great videos. They are a great help.
Rich solar is looking better and better 👍
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
You rock young brother, I actually learned a bunch from your videos, you give a very clear and simple instructions...
Hi. Great video. I am still struggling with whether I need a MPPT specifically designed for my blue carbon LifePo4 batteries. 4 in parallel for 800ah. I have 1500 watts of solar on my boat. Or if I can use any MPPT?
I have a 40amp Epever and can't seem to find a way to program it to properly lifepo4 settings without a PC computer. Is this possible? Or, which controller should I get (even if I must go to 50-60 amp controller)?
I don't want to program it from a phone or computer.
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.
16:14 Connecting two panels in series to a PWM controller. Great idea! I was just wondering if that would work. Besides that and a few percent efficiency in charging, is there any other advantage an MPPT has over PWM for a small system? Thanks for the great videos, I've watched a bunch today. Oh do you have a link to the 24v PWM build?
I want to know the same
Me too... I'm new to all this.
PWM best conditions are among others. Similar voltage in and out. The further away, one get from this, the bigger advantage a MMPT have on a given system!
Example:
- 12V nominal panel(s) to a 12V nominal battery, perfect condition for PWM!
- 24V nominal panel(s) to a 24V nominal battery, still perfect for PWM
Following similar example. 24v (36V or 48V...) panel to 12V battery, PWM not good at all! An MPPT would be way better on this condition! ;-)
In other words if everything is perfectly matched the PWM perform quite decently , in fact the best ROI possible! (Return Of Investment).
On the other hand step away from these perfect conditions. With dissimilar panels, voltages, partial shading, etc. that's MPPT territory! ;-)
For a simple 12V or 24V system, it's a direct and simple hook up! Even the cheapest PWM controller shown here. Will automatically switch from 12 to 24V. Cheap simple and easy! ;-)
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
What if your running 800 Watts of PV? You need 60A. A comparision of that level would be interesting because there is less incentive to make them cheap at that price point. I would like to see a nice mid range system test although the cheap end of the spectrum was also interesting.
What is the max power rating of each single panel? My research would suggest MPPT is more advantageous when there is more voltage, so a single panel test would not demonstrate the differences.. eg, if you measured each with 2 panels connected, parallel and series, the results would be even more interesting. Good review
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
As a total newbie I have to say, you are amazing!
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 wonder if Renogy has addressed the terminals since this video was posted. Spec sheet indicated 8awg.
I know you can't read all the comments so hopefully some people would like this one so that it will get your attention but if there's any way you could do a schematics or a person that was scalable kind of like this trailer but for RV maybe the concept that you have right there will work but a lot of my RV appliances run off 12 volt I'd be willing to by the battleborn batteries as well just would like to do it on myself and don't know what inverters would be best thanks
I am over whelmed, over loaded, my brain circuits are HOT🔥🔥🔥
You are way too funny. I know he kind of talks fast, but if you listen long enough, he makes sense. Don't give up. Just try again, again and again.
Thanks for helping me to wade through solar controllers and amps, watts, volts, etc. I live in Haiti and depend heavily on solar power!
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
Enjoying learning about smaller scale solar. Late comer to the channel, but anyone mention that you are the solar Sheldon?
Wonder if I can use one of these, because my solar panel gives a output of 40 volt. And you showed me a setup at max 12/ 24 controllers. Thx b
Great video Will, do you think the MPPTs with two 100w panels in series will out produce the PWM with two 100w panels in parallel? I'd love to see data over time to get some realistic use type stats. Again great video!
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
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
Can you have, say 6 solar panels and divide them in two groups of three, using one 30AMP controller on each group to charger the same battery?
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!
This is a really nicely put together comparison. Great for people that want to get the basics and install their own solar.
Such a good job. You are also very cute.
Baby you need the bogart engineering 30 amp PWM cc and battery monitor!
Can you tell me why my Renogy controller only charges one-tenth of a volt more than the battery has. No matter what the battery voltage is. This solar power is confusing. Thank you. Hank
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.
"This one feels like a McDonalds kid's toy." LOL
wouldn't be surprised if they got McDonald's put it in the kids pack meals as a toy lol
hey kids try out getting into solar and save money on free power
I laughed too. Even more so when I realized this was the unit I am considering. But then, I'm 'only' trying to re-charge a small sealed lead acid battery to power a trail camera.
@@ME-kq4wp - I have several of those. In spite of no failures, really cheap prices, easy usage, etc. I do advise to get a slightly better PWM! Cost wise they're unbeatable, but as mentioned having a temp sensor can be useful in some applications! Cheers
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.
Informative video and congratulations on passing 60k subs.
that cheep $3 one I have had one of them for the last year, no problems before that an even cheaper one my lead acid battery where cheep as chips 6 yr back from eBay infact they were the cheapest on eBay at the time + still working ok
An updated version of this video would be awesome!!
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
