The only confusing thing about all of this is which one is best to charge your batteries? When living in the van, you’re using amps, and concerned with how many AH your bank has. Do you want to push the most amps into the battery, or the most volts into the battery? Nobody bothers to tell you which is actually preferred or which will charge your batteries to full faster. Could you please cover this?!

Im having a bit of trouble with my system. I have everything set up but my charge controller even tho it's setup in direct sunlight the charge controller is stuck in night mode.

So my array is 16 250 watt panels, 4 strings in parallel. The current @ pmax is 8.27. The volts @ pmax is 30.3. Open circuit volts are 37.6. Not sure which volts to figure but i guessed the 30.3. Im coming up with 121 volts and 33 amps. Is that correct? Then im shopping for a charge controller and they all say 12v 24v 48v etc. What size charge controller do i need? And inverter as well? Its not too confusing but im brand new to this and i cant afford to screw it up. Thanks

have a question regarding my particular panels that i bought literally 20 years ago and am just now getting a house i get them set up in... yeah yeah i know - mean to... the label on the back says 101w, but the vmp is 96volts and the max amps is 1.42... how is that even possible? the math doesn't work. if it's a 100w panel at 1.42, the voltage should be 70... frankly i didn't look but when i hooked them up i could have sworn they were 100w at 12v, so i had them wired to charge 48v battery bank though a 48v controller... what am i missing. after so many years, i can't even go back to the manufacturer... anyone have an idea? i did a volt test on the array and it does show up at about 400v - VOLTS... i thought i had the multimeter set wrong, but then went to a single panel and tested it and yes, it's a 100 volts. so the question is, can i even use these panels?

I have 3 x 40v panels in parallel connected to a 24v system and today its a bit cloudy and the panels make less than 24v only 6v aswell. so of course it cant charge , but why? shouldnt only the amps drop with shade, why the voltage? if i connect them in series i am not sure if i solve the problem because if 1 makes only 5-8v i am still not reaching more than 24, so whats the problem? always when i measure the output voltage directly from the panels, its always about 37v with strong sun and when its cloudy aswell, but as soon as i attach them to the mppt the voltage drops to 6v or less

Good Morning ! Does this mean i could use 9 gopower 190 watt panels in 3 arays and work with the 10 ga wire all the way down to a victron 150/100 controler ?

I just installed 9500 GPH sump pump for a fountain in my 1/2-acre pond. I have 2 100Watt 12V solar panels with 30amp controller and 600-watt inverter and 3 lithium batteries 12V 20aH. Unfortunately, I'm only getting 8-10 minutes per hour of run time before the alarm goes off and shuts down. Do I need to add more panels to accommodate or add more batteries or both? Should i go with 12V 100aH lithium batteries over the 20aH that I have or add 2 more 20Ah. Which is best for panels and batteries series or parallel?

Great videos. Which configuration would charge a battery fastest? For example, does wiring it with higher voltage but less amps result in slower charging due to lower amps, or does the higher voltage increase the speed of charging?

I had my panels in parallel. Changing them into series-parallel really increased the amps into the batteries. My voltage into the charge controller was too low. Increasing the volts increased my amps. Thanks a ton for these very useful videos!

Nate I was able to get 150/100 MPPT Victron charge controller at a really good price from a friend but still confused on the best way to connect (Six) 100 watt panels using this charge controller because I could hook them up in series and still not reach 150 volts or I could hook them up Parallel and still not reach the 100 amps. Should I just hook them up Series Parallel and never give the charge control a real workout? How would you do it? Is using the Victron 150/100 a problem with my 600 watts of solar and 400 amp hours of batteries? Thank you for your videos I fall back on them all the time I need a refresher.

Finally someone explaining not just the maths, but why you’d do it. I’ve been looking for this info for a while. Great job.

How could it still be confusing after the amazingly great way you’ve taught this. The combination of your succinct and accurate words alongside visuals was the best I’ve seen yet. Thanks for all the time you put to this.

You're doing great sir! I'm a few years behind but am glad to be here now.

Sending a link to my professor at university , hope he learns how to teach like this! Clear diagrams, relaxed attitude and passionate about the topic . Inspiring . You can learn a lot from fellas like this chap .

These are incredibly helpful videos brother! Thank you for sharing your knowledge.

The quiz was great. I failed before your presentation, and passed after. I appreciate the work you put into the videos and the quiz.

As one that has taught and instructed, having a interactive portion is a fantastic way of developing an understanding.

Your videos are helpful. You helping a old man to be able solar up his Class A motorhome. I never want to old to learn. Thank You

Oh my! I’ve had sooo much trouble wrapping my mind around this! Thanks so much for the simple video. I learned so much in 10 minutes!

This is EXACTLY the video and information I've been looking for!!! THANK YOU!!
