Wow! My degree is in electrical engineering and I have a pretty good understanding of electrical stuff. I think this is the best video I have ever seen describing the difference between a PWM and MPPT solar charge controller. That is saying something because there are some bright people on UA-cam talking about the same stuff. Good job!
I just upgraded my small 200 watt system to a MPPT charge controller, and what a difference!! It turns on way earlier in the mornings and shuts off just after sunset. It charges up by batteries in about half the time as my old PWM did. Real world conditions, real world testing. Greetings from sunny Jamaica.
I'm glad I watched this. I am buying an RV and didn't realize how much stuff you should know about power, water purification, gadgets, etc. It would be overwhelming without videos like this.
Just getting into boat sailing and your explanation of the chargers was very useful, however I think you could easily do without the background music, your audio doesn’t need jazzing up. Thanks again.
You are 100% correct in using an MPPT with a portable solar panel or blanket to maximise the output. On my small garage (fixed hobby) solar system, it was easier and slightly cheaper to just add another 100w panel rather than upgrade to MPPT. The extra panel was about $125, about $50 less than a new MMPT.
This is the BEST explanation of what normally could be a very complex description of how these converters work but also their differences. Again, many compliments.
Have been researching setting up a 12v system for camping and another 4WD youtuber was recommending MPPT over PWM, but never went into deatils as to why. Thanks for showing me the "why" in easily understandable terms. The graphs laid it out clearly for me.
great explanation, thank you. Went away for a quick trip with a 200w solar blanket, 85ah battery and a 15ltr Waeco fridge, had three days of heavy cloud where the battery went flat. Now I know why PWM and solar blanket flat on the ground. Will be buying a MPPT regulator and angling the solar blanket.
I found your video while looking at a different one. You explain PWM and MPPT a lot better than the other one. I still need to gain more understanding of watts, volts and amps, but your video is a great start.
You know what, its the best video explaining MPPT charge controllers. I watched so many videos on this subject, particularly on channels referring themselves as 'expert' on solar systems, this one beats them all. Thank you
Excellent description. I normally hate the soundtrack on technology videos because it is usually some sort of crap keyboard techno music, but I love those blues on slide.
A very nice, concise and understandable comparison with a quite satisfying technical explanation for a first time solar enthusiast. Well done. Thank you!
Thanks Cahn. Great job taking the "load of info of it all" and filtering out all the stuff that makes it confusing to a level laymen can understand. Cheers
Thanks for a great video. I fully agree with all your statements as it is what I have also found. The plus side for MPPT just gets better the bigger the difference is between panel Volts and battery Volts. If only more people would look at the results during the actual test.
Great Video! Firstly, I'm about to change from an AGM to a Kings LIfepo4 battery with BMS, do I need to change the controller to a lithium controller. Secondly. is the battery connection a 2way operation. For me at least a quick vid on how the wiring actually works would be handy. Love the professionalism you guys brink to the tube.
Thanks for the indepth explanations of how the two types of solar charge controllers work. Best I've heard. I believe, however, that many pwm charge controllers, even the umbiquitous cheap ones, can do either 12 volt or 24 volt, but they cannot modulate or change the output like an MPPT so your panel voltage has to match your battery set up voltage. MPPT are more flexible and with some of the higher end all-in-one combined MPPT charge controller and inverter, you can line your panels up in series from 120V to something like 440 volts, allowing crazy pv string voltage! So a lot of that depends on the model. They vary widely.
@@simonpepper9721 sorry, you didn't get what i was saying. I was saying in satire that you definitely have not watched all the videos on youtube about them haha. there are plenty out there and to be honest 4wd supercentre/Kings is the last place you should be taking battery/solar/auto electrical advice from. They are an on-seller of products. There are a plethora of electrical-based youtube channels that are far more qualified to give advice
Thank You Very much for this video, I have been searching all day for something that broke it down the way you did, it makes me glad I went with an MPPT charge controller!
As a work around I use my Bluetti ac200p and a 500w lifepo4 charger to charge my 4 lifepo4 12.8 100ah batteries while feeding my Bluetti 1000watts of solar..This works fine for me, I’m just using my Mppt charge controller in my Bluetti…I get needing a Mppt controller if you’re using just batteries for power…
Good grief I've searched all over, asked ? After ? What solar regulator I'd need, finally came across your video, thank you! Woohoo feels like I'm on the right path in deciding on solar power for my van. I have to have a AGM battery bc it will be inside. Been racking my brain trying to know the safest regulator to charge my battery and get the most out of a 100 watt panel.
Well explained. Especially that the PWM is only 70% effective. Nobody ever mentioned that. I now made a trickle charger for my SUV standing in the garage with me working from home mostly. The battery goes flat after 2 weeks, so. I used a cheap 200W solar panel and PWM controller. It works perfectly. It keeps my car's battery charged. In this case I did not need a MPPT controller. So I suppose PWM is still useful for low key applications.
Hi Sathya, Thanks for appreciation mate. If you need any assistance with purchasing solar and mppt controller, feel free to contact us on social@4wdsupacentre.com.au and we can go over best prices and deals with you then. Cheers, Saleha
@@4wdsupacentreAu sounds great saleha. Today I just went to weatherhill Park, bought 20A MPPT, connecting it with existing Full river battery, redarc dc dc charger, redarc 80W solar panel mounted. Bought few other kings products such as lights, awning, fridge etc.
Nice explanation. The problem now that most people know about MPPT is being exploited on eBay as many of these PWM controllers are being advertised as MPPT. It will say MPPT in the title but if you read the fine print, it will say PWM. I responded to a couple sellers, and they just use the excuse that the marketing dept needs to fix the problem.
I also have found increasing levels of dishonesty on eBay. For instance, if you search for a 200W solar panel, many are way too small to crediblely be anyting more than 80W. Similarly, steel is listed as "marine grade stainless' when it corrodes after a few weeks. Ebay needs to fix this problem.
My initial question was, whats the difference? NOTE: As a master automotive tech, intimately familiar with 12v systems, Automotive oscilloscopes, and what PWM means, as solenoids and idle air controllers ect. are operated as such. With my next question being "how do i stop it from cooking my batteries and keep my charge voltage at13.4 to 14.4. and my third question being can i use higher voltage panels without wasting money. All questions answered. You are the MAN.
FYI found Renogy Rover 20 Amp 12V/24V MPPT Common Positive Solar Charge Controller Regulator Compatible with Lithium Sealed, Gel, Flooded Batteries and Bluetooth Module. $81 US
thanks for the video. i wish more people talked about the specifics like this. i would add that another benefit is mppt controllers normally allow for wiring your panels in series, so you can get the same watts, but decrease your amps and have cheaper cables so you can place the panels farther away from your site, maybe even out of the shade, or leave the amps the same but increase volts, therefore increase watts.
That's true I have another 48v system, I use 3 mppt charge controllers each connected to 8 solar panels 4x250w + 4x250w . I use a 700ah forklift battery which are 2vx24=48v , I have 2 inverters which I alternate. I use fridge, 42 inch TV , microwave , kettle, water pumps and lights this is the 5fth year with this system and still going on I'm connected to national grid but I do not use it so I'm almost recovering my initial cost I also have a 2000w wind turbine which supplements charging during windy periods. I was experimenting possibility of planting off grid and have now archived my goal so the way forward is mppt charge controllers
Can I put the dc to dc charger under the bonnet? My other battery is under the bonnet connected to the solar panel via a pwm controller and I want to change it to a dc charger.
Great video thanks. Correct me if I am wrong but another advantage of MPPT is that they can often take upto 100v input to reduce losses. Another too is quality MPPT can be programmed for different battery profiles like AGM v Lead acid v Lifepo4 the latter requiring a very different charging regime eg 14.4 v boost, never equalising and a float of only 12.8. I believe all quality MPPT can do this. Have also been told PWM can reduce the life of a lifepo4 battery as it can not deliver the custom profile needed for that spec.
you are not wrong that I know of, but some of the latest MPPT controllers are 150V models, so you can do even longer strings or use higher output panels.
Great, thanks. I'm finally convinced 🤗 and upgrading all my systems to MPPT. I believe the extra cost of the MPPT controller is negligible in comparison to the benefits of the extra available power.
With your 120W solar blanket I am consistently getting 25 to 30% more power output from the PWM compared to all of the big brand MPPT charge controllers I’ve tested. Why would that be? Isn’t meant to be the other way around?
For PWM you need to connect panels in parallel, up to the rated input current. For MPPT you can connect in series up the the rated input voltage of the controller, then you could add psets in parallel up to the rated input current.
i want to add a panel and mppt chare controller as a portable panel 100w what items do you suggest? lithium battel bone batteries 200 amh, my intent is to use this when I am in the shade and hunt for the sun. GREAT job.
Hey I love your channel I'm gonna go with the one you mentioned the last 1 I have 200 W solar powered panels on my truck they both put a 100 W out I haven't learned how to hook everything up yet but I was looking at that PTFI can't say a word anyways I'm still watching you and I still like it I'm learning a lot from you now I know which 1 to buy I don't always get to watch you but tonight I'm glad I clicked on you
great video. However I have installed my mppt....mp3743 and I am having difficulty understanding how to adjust the controls on the panel. Do I have to insert time on and time off to allow for the battery not to drain right down. A warning light E2. each morning the only way to get the unit to function and start charging is to plug in my 240v power to house lead then remove or use my generator if away from home.
What happens with an mppt controller when the voltage from the solar array is less than 12v, say in a very cloudy day? Will it boost the voltage to 13v so the battery can charge, albeit at a lower current?
If I want to build a 3kva solar power myself in my apartment, 1. how many watt of solar panels do I need 2. How many arms of charge controller do I need 3. How many arms of battery do I need 4. How many watt or arms of solar inverter do I need Will really love if you help. Thanks
I’m trying to find a video breaking down what lights should be on constantly or flashing… my solar panel light is a constant which the user manual says “Solar panel voltage is higher than the light control voltage” and is should be pulsating but not rapid. I noticed in this video yours is a steady in as well. Can someone please enlighten me. I’m new to this set up and struggling to understand if I have a faulty MPPT. thank you
Very good comparison, i know MPPT controller can abstract over 90% of the solar power the solar panel receives. and PWM shall be around 70% or even less generally. But i never do such experiment to get real data comparison. good video. thumb up
Hi there mate. I’m new to solar and batteries. I have a kings batter box which has 12v and USB outlets on it. It seems most solar controllers have power from panels in. Power to batteries out. And 12 volt load out also. Can I just feed panels into controller. Then out of controller into battery. And then use the low voltage outlets on the battery. Do I need a specific controller or can I use a standard one and just ignore the 12v terminals? Does any of this make sense? Cheers and thank you. John Davies.
Hey mate from memory I bought it from Jaycar but you can get them online and most electronics shops! Not 100% accurate but definitely close enough to be very useful! Cheers Cahn
I have a 250w solar panel and it has the MPPT 20amp controller (kings) attached, charging a 138Ah AGM with the Kings 12 v battery monitor fitted on the maxi battery box. Yesterday i brought a new 120 Ah Lithium battery and a 15amp PWM Solar Controller. (the 138Ah is too heavy for my back) 1. do I have to use the 15amp PWM solar controller with the 250w panel charging the 120Amp Lithium or can I continue using the 20 amp MPPT that was originally on the solar panel I brought last month? 2. Can I continue to use the battery monitor I brought last month with the new Lithium battery ( maybe turn down all the low voltage and turn up the high voltage settings and run the monitor on AGM?) please advise best action I should do. regards Peter
With the mppt modulator what r the chances of overheating the system and does it reduce the life of the solar panel and can this also void the warranty if using and something happens anywhere in the circuit of the charging system.I have the TJM solar panel
So, now can you explain what the benefits are of not installing bypass diodes in your panels to mitigates against total power loss and hotspots due to partial shading?
also dont cross the wires on the accessory port, I had allegator clips to charge a secondary battery and crossed them and the controller went POOF smoke and the smell, when I opened the controller the circuit board was melted luckily it was only a cheap 10 dollar one

I’m new to solar and batteries. I have a kings batter box which has 12v and USB outlets on it. It seems most solar controllers have power from panels in. Power to batteries out. And 12 volt load out also. Can I just feed panels into controller. Then out of controller into battery. And then use the low voltage outlets on the battery. Do I need a specific controller or can I use a standard one and just ignore the 12v terminals?
Does any of this make sense? Cheers and thank you.
John Davies.
Excellent work explaining, a great video
I have questions about setting up my truck with solar panels I have a few things but I need advice
Hey there.
Which battery setting does the PWM need to be in for my kings 120ah lithium battery??
Many thanks
Good video I'm trying to understand it but I'm not really good at this stuff but we'll try and see what the stuff means
They do make 24v pwn charge controllers for 24v battery banks but i would still use mppt for a 24v battery bank
What brand & model is the in-line Anderson cable watt meter used in this video?
Hey mate from memory I bought it from Jaycar but you can get them online and most electronics shops!
Not 100% accurate but definitely close enough to be very useful!
Cheers

How do you bypass a solar regulator on a panel ? I have a D C D C charger on my power station and need to turn off the regulator on the solar panel.
I have a 250w solar panel and it has the MPPT 20amp controller (kings) attached, charging a 138Ah AGM with the Kings 12 v battery monitor fitted on the maxi battery box.
Yesterday i brought a new 120 Ah Lithium battery and a 15amp PWM Solar Controller. (the 138Ah is too heavy for my back)
1. do I have to use the 15amp PWM solar controller with the 250w panel charging the 120Amp Lithium or can I continue using the 20 amp MPPT that was originally on the solar panel I brought last month?
2. Can I continue to use the battery monitor I brought last month with the new Lithium battery ( maybe turn down all the low voltage and turn up the high voltage settings and run the monitor on AGM?)
please advise best action I should do. regards Peter
The 15 amp pwm will limit your power to 15 amps. So your better of using the 20 amp pwm.
Brilliant. Very well explained and demonstrated. Worthy of subscription.
What about battery types with each controller can they both charge all battery types.
With the mppt modulator what r the chances of overheating the system and does it reduce the life of the solar panel and can this also void the warranty if using and something happens anywhere in the circuit of the charging system.I have the TJM solar panel
Why cant my kings 200w panel start up my 25w dual charger but it works with the PWM regulator???
Got the cheap pwm, 30 amps, using it on a 36v , 170w panel, works OK, it says, it can take 50 max,
Your only getting less than half the power out of your panel with pwm. Mppt will reduce the voltage and double the amperage.
So, now can you explain what the benefits are of not installing bypass diodes in your panels to mitigates against total power loss and hotspots due to partial shading?
also dont cross the wires on the accessory port, I had allegator clips to charge a secondary battery and crossed them and the controller went POOF smoke and the smell, when I opened the controller the circuit board was melted luckily it was only a cheap 10 dollar one
Can I connect two 12v panels together making 24v to a mppt to charge a 12v system many thanks
I have a Xantrex C40 PWM charge controller and it accepts 12, 24, and 48 volts and and supply needed current when inverter demands it.
You might like XT60 or XT90 connectors over them big clunky Anderson 50’s you are using.
