MPPT VS PWM || Solar Charge Controller

You can get the controllers shown in the video here (affiliate links):
MPPT:
PWM:

In this VS episode I will compare an expensive MPPT solar charge controller with two cheap PWM solar charge controller from China. I will mostly talk about how much power they can draw from the solar panel and when it makes sense to use a cheap PWM controller and when an expensive MPPT controller.

What? A video on friday? Long story short, I will be going on vacation tomorrow and take a small break from producing videos. So this is basically the video for sunday. But don't be scared, there will probably be another video ready for the next sunday.

4 years later this information is still gold... Anyone else admiring the neatness of his handwriting? That alone makes the video more plausible and the results from the calculations, as well as his conclusions more believable. 😃

[Kabodanki]

for some reason I find this really satisfying seeing your face saying "Stay creative and I will see you next time"

The final calculations were shocking to me, but they confirmed how AWESOME you are to not hesitate to show real numbers even if you don't like the outcome. Keeping it real! I like that!

Mppt really comes into its own with larger systems where the PV voltage is configured to be much higher than the battery through series connection of panels. In either case though, the energy harvested over the whole day will be significantly greater with a good mppt controller. Really enjoyed the video mate, cheers!

I saw you face GreatScott at first time. Thank you very much great video every times. Especially I love your schematics drawing beauty. Thank a lot.

For many people the solar efficiency is not a monetary matter. Instead...it is their only way to obtain any energy so the extra power you can capture on any given day is priceless. Nice video!

[TheKillerjohny]

Yep he is human after all. Just like everyone else. Do not panic people.

[leroywarner]

Excellent both in writing and in verbalizing clear into the point

[micahmills]

You forgot one of the most important points about MPPT vs PWM! Most PWM controllers will not work until the output voltage of the panel reaches a certain voltage, but a MPPT panel can boost low panel output during early morning and evening sunlight. This means that you get more hours of battery charging during the day from MPPT instead of PWM.

[RodLucanor]

My sincere respects for this guy who take seriously efficiency analitical energy costs. You are a true hero. Cheers from Argentina!!

[MasterXXL]

Something that you didn't mention is the main function of the MPPT is to vary the voltage or current in order to maximize the power generated depending on the temperature and irradiance of the PV panels. This is specially important during days with lots of clouds in the sky since partial shading of panels can really decrease the power generation if this is not compensated by an MPPT module.

GREAT VIDEO!!!

And I agree with everyone else. SO GLAD you finally came in front of the camera!!! :-D

[BeezyKing]

although I've only subbed recently.... now i finally find the video that reveals the face behind the voice... so clear yet concise... overall I gotta admit I am learning from your content as time goes on.

[norvinsakiral]

This is my first time to watch your video with you in the front explaining anything.

[NavinChoubeyB]

finally got to see man behind such a great show, thanks for being inspiration for plenty of my diy projects.

[dalahmah]

I think the true value of the MPPT will become apparent when there is partial shading on the solar panel or when it is cloudy.

[genuino-qoyq]

Can't wait for a diy mppt charge controller...

[wakzy]

This is a really good presentation. You have included considerations that nobody else has thought of. Good work.

Video quality just got better, keep it up scott
