The water-through-pipe analogy helped me best come to terms with it all. Thin pipes move water faster, and fat pipes get the same volume of water through but at a slower pace. But at the end of the day you get the same amount of water in your cup.
Nate, your ability to explain with clarity blows me away. I am an electrician and industrial maintenance technician and know this stuff like the back of my hand, yet when I try to explain it I'm falling all over myself. Hats off to you, my man!
I remember the formula because the A has one sharp point, the V has one sharp point, so you multiply them together to get W with 2 sharp points (in the same direction). Just a little mnemonic I use. 1 point and 1 point = 2 points. A * V = W

great channel i have since built my own 24v 6,6kwh 1.4kw solar ,after learning from this channel ,panel wiring ect ect been running great for over 18 months ,runs most the house
Volts are what is given to an appliance. Amps is what is taken by an appliance. The combination creates the amount of watts needed. At least that is what I figured out on my own anyhow. Very good video. Thank you. Subscribed. 🙂
I absolutely LOVE that you’re able to break these kinds of things down to simplicity that even an idiot like me can understand. I was able to build my solar system with confidence thanks to the solar video you did like this. Thank you so much!
Exactly the video I was looking for. Somewhere my college physics professor from yesteryear is shaking his head disappointment at my lack of retention. Thanks for the great video!
6:28 Clarification regarding "Running appliances at a higher voltage". I should have said: "Choosing appliances that operate at a higher voltage". We don't really get to pick and choose what voltage an appliance operates at aside from choosing a different appliance (12v DC air conditioner vs 120V AC air conditioner vs 240V ac split phase air conditioner) ➤Shop the EXPLORIST.life store: shop.explorist.life ➤Shop Battle Born Batteries: battlebornbatteries.com/?afmc=explorist_bb67 ✅Use code 'explorist' for $50 off per battery.
True, though some motors can be wired for either 120 or 240, which can be handy should you be able to upgrade a workshop or such from 120 to 240 in the future.
The simplicity in which you have explained these things is very helpful for simple-minded people such as myself. Nate, you are a blessing brother! And I look forward to watching more of your videos to get a better understanding of electrical in a camper.

Well... I am going back into PV and I can only comment " I agree with all comments below" can't say anything new. You did a great job conveying the knowledge. Thank you,
New subscriber here. My goodness FINALLY a comprehensive simple explanation of power compsumption. I wish I had seen this a week ago. THANKS so miuch for this video.
I like to think of it like this: Imagine workers carrying batches of electricity through a hallway (which is the cable). Wattage: how much electricity needs to be carried Voltage: how strong workers are; how much electricity each worker can carry. Amperage: how many workers are needed to carry the electricity. So, the lower the voltage, the less a worker can carry; which means you need more workers. More workers need more space in the hallway (cable) to be able to walk together, so lower voltage electricity needs a thicker cable to be carried. At a higher voltage, each worker can carry more electricity, so fewer workers are needed, and therefore, the hallway (cable) doesn't need to be as wide to accommodate them.
I love these videos! I think you guys make up 2/3 of my van build resources playlist haha. I definitely need to come back and rewatch some of your electrical ones, they're worth a couple repeats!
Great Video. I remember the basic formula's (Ohm's Law) as E=IxR and P=IxE where E=voltage, I=current, R=resistance and P=power in watts. It would have been nice if you had explained that what you did there resulted in about one hour battery life (120Ah battery) and if you add batteries you double the time use of the load. Its also easier for the novice to understand if you use 12V, 120V and 1200 watts. I also like that you explained why 24v and higher systems are used: lower current = smaller wire size = money saved. Explaining any electrical or electronic theory is tricky and you did a great job!
Great video - I'm trying to figure this all out right now. I purchased two 280ah batteries with a 24v inverter. I will be using solar to charge the batteries via a victron controller. This helps me understand what I can run and what I can use through the night when there is no solar charging. Very helpful. I'm going to use this in my spreadsheet to hopefully make it all make sense.
I Absolutely LOVE your style. You are so clear and concise. I've literally watched dozens of videos that give some of the same information but still did'nt quite get it. After your video one time it fit all the pieces together and answered all of my questions. Most people who explain this formula neglect to add the point that by adding "hours" to the amps and watts that you can figure out anything you need to. I appreciate what you're doing and I'm a big fan. Will be watching many more of your videos.
Finally - I hope everyone watches this video. Describing your battery system in amp hours is like saying you get miles per gallon. You are missing an important part of the equation and illustrates to someone with knowledge that you have no clue what you are talking about. As we move into Lithium, another key item to know is 3.2v per cell - this makes battery sizes 12.8v, 25.6v & 51.2v. I have a 600 amp hour system at 25.6v - so 15,360 watt hours of capacity on my coach. Nicely done video - thanks!
Good explanation. I always use "watt hours" to describe the capacity of my batteries, and most people dont actually know anything about electricity beyond what they see on TH-cam, so they are always confused when something other than "amp hours" gets mentioned. "Amp hours" used in discussion is only generally relevant if you ASSUME the battery bank is 12v. My bank sounds much smaller than it actually is when I say I have 540Ah (because its 24v)- I always have to caveat, in 12v terms, its actually 1080Ah.
Nate thanks for the tutorial on the electric, I have been building Vintage looking Teardrop campers for a while and I am glad to find this extra knowledge
Wow! Mind blown! I honestly thought I would have to take an electrical class at a community collage to understand W=AxV. Well.. I will need to watch this a few more times but this is SO HELPFUL! Thank you!! The voltage! All I thought I wanted was 600 amp hours with a 3 to 5,000 (amp or watt) inverter. With 1,000 watts of solar. Apples to apples… I think I pulled something
I have just started doing my van conversion and am on the insulating stage this week, so I have some way to go before i get the electrical. The one thing that is making me think I have made a huge mistake is all the wiring I need to do. Your videos are helping me a little, but it is still very overwhelming, and the kit you use is very, very expensive. I am looking at 5 amg batteries at 120ah each backed up with 900watt of solar. I need to run 3 sets of 12v lights, two 12v fans, one 12v water pump. I need to run 2 hot water heater 240v (shower+hot tap), a 240v fridge, a 240v TV, a 240v induction hob and my oven will be a 240v air fryer. Then I will have 3 wireless phone charger pod with two 240v sockets with 2 USB built in. This all sound like a lot to have but obviously will only be running one or two things at once like the TV and lights or the air fryer and lights but I have no idea where to start. Am I better to go with a higher volt or amp set up (series/parallel)???
thanks so much for breaking this down to all the beginners out there. now I have something to share with my friends that are interested in basic electricity and electronics.
I knew the concepts discussed before but am not convinced that it was the best way to explain it. Once you got into watt hours and power the 1200W space heater, things got a little murky. I had to replay parts to understand what you were saying and if you were saying something I didn't know.
Yeah, so when you already know something, you will be watching my video from a perspective of self-validation instead of learning. Ultimately, you aren't my target audience here. If you think you've got a better way to explain things, you can always upload your own video. I know that takes a lot more effort than just leaving a comment talking shit. 🙄👍
I’m currently trying to upgrade a system that was already built into this little cabin. The battery bank needs an upgrade and I am considering switching from 12v to 24v
Nate, I’ve watched some of your other videos on this stuff and didn’t under stand anything. This was the first one I was like hey this makes sense! Thanks man! I can tell this is your favorite part 😂
Awesome explanation and straight to the point. I prefer these videos over my college courses of 3 hours of pure blah blah blah blah. By the way, I would have prefered to use 12V instead of 12.8V to make the calculations easier.
Great channel man this helped me understand a lot. Actually learned a lot of that in welding school so many years ago but for got a lot of the book stuff. I always remembered more volts = less amps
Something here I don't quite understand: At around the 5:00 to 6:30 point on the white board you show 2 examples, 1 with 12v and one with 25v and the amps for a 100w light bulb. 12v is 7.81 amps and 25v is 3.90 amps. So off I go to do some google searches. What I found was pretty different then what you are showing for 100 watts and how many amps DC or AC that would equal. I'll just have to re-watch and re-search and try to figure out what I'm not understanding or what I am missing.
Thank You,for a very informative and easy to understand vid. I am not an electrician (more of a Jack of all Trades), but my son-in-law wants to run underfloor heating from solar panels/ battery banks/inverters. So your vid is going to help me tremendously with my calculations.
Finally, a video that doesn't use water as a reference. This makes sense. Thank you very much. I had a general understanding of electricity but not the full function of power transfer from a power storage. Do you have any videos on the difference between 12 - 48v lead acid batteries and so on. I can really do with that knowledge
Nice job explaining. One good thing about going in series with 24 volt is wire size. I go for 12 volt and spend more money on wire and save on things that run on 12 volt.
I've noticed that some of the all-in-one power units (Bluetti, Ecoflow, etc) are starting to label systems/batteries in watt-hours. Just seems to make more sense and easier to calculate run times or percent usage from power loads.
I find that cheaper brands and cheaper devices tend to rate things in a way to make it more confusing (On purpose). What ever number sounds better to an amateur.
This video really, really helps. Thank you so much for breaking this down like this. I keep having to come back to this video because I forget the formulas. Extremely helpful, thank you!
Thank you so very much. This really did bless me I’m going to save it. It’s going to take a bit of study for me though. But thanks to your excellent teaching, I’m going to be a lot farther than I was.
good expain and understanble but I have a question : why we measure the difference potential to about 400v or 390V or so on in three lines circuit ?? as long as every line have a potential and none of them is neutral is it must be 0 instead of 400V ?
Very good I'm as green as a frog in solar newbie you made the simple formula easy for me now to understand what all those and why all those guys said what they did about smaller wires costs down 48v vs 12v thankyou now I know what I need to do to plan my families basic solar unit in Philippines because it's always brownouts for days. Thankyou
Nate, hats off to you. This is the best video I've seen on the subject because of its clarity and simplicity. I just bought 4 new 12V batteries for my semi. I believe they have 100ah each but I'm not sure. So let's assume they do. They use a parallel connection. So I was wondering if you could do a video illustrating WHY semi trucks (as well as other big vehicles) use a parallel connection instead of in a series.
very cool. I am trying to figure out if I can build a battery bank of 4 12 volt batts to b 48 volts. and deliver 1000 watts. so I will have to learn this math at some point. this is the best video I saw so far. but I am not tech savvy. so I ll see if I can pull up more of these
So quick follow up question. To calculate total time using the lightbulb example, with the battery not plugged in, you just take the 100ah / 7.81 ah, which would be roughly 12 hours? Is that correct?
Darn I couldn't figure it out great explanation but I couldn't figure it out If I'm going to run a 48 volt system can I run three 300 amp hour batteries12 v and one 200amp hour because that's all I have. Or will that decrease my amp hours immensely because one is only a 200.. . They might all think they're 200
The "Ah Ha" light is starting to flicker. My old brain is wrestling with this as I am trying to build a system for my teardrop trailer but thanks to your help I am seeing some hope and faint memories of 10th grade electronics class. Thank you.
Hey Buddy, thanks for the Vid. You definitely taught me some stuff & you can explain it better than I can. I did notice one thing that could of just been an mis-write, in the beginning of the vid there were (2) 12volt parrelled batteries, the positive & negative wires were both wired to one end of the battery bank instead of negative on one end of bank & positive on other end of bank for even/equal current flow. Thanks again for the video bro!
See any of our full installs videos or wiring diagrams for more info on how to actually wire a battery bank. I also didn't show any lugs, fuses, wire sizes or heat shrink in the 101 level concepts-only video. Don't nit pick me on off-topic stuff like that. 🙂👍
Thanks very much. So we really don’t need to know watt hours right? We can just jump straight to how many amps and volts to work out amp hour required. No need to use watt hours at all?
I hesitate to ask such a elementary question, 2560 Wh shown above, does that mean I can run a 100watt lightbulb one hour = 100 Wh divided by 2560 Wh to get time of contiuous use... = 25.6 hours
newb but watching 1000 videos explaining this is slowly starting to sink in. thanks!! :)

Hi,Nate,So I bought ADCBATT 12V 100AH Lifepo4 battery, W=1280? Is that how it is calculated?
I remember the formula because the A has one sharp point, the V has one sharp point, so you multiply them together to get W with 2 sharp points (in the same direction). Just a little mnemonic I use. 1 point and 1 point = 2 points. A * V = W

I'll just have to re-watch and re-search and try to figure out what I'm not understanding or what I am missing.
Very clear and informative video. I highly appreciate and recommend your job. Thanks a lot.
Thank You,for a very informative and easy to understand vid. I am not an electrician (more of a Jack of all Trades), but my son-in-law wants to run underfloor heating from solar panels/ battery banks/inverters. So your vid is going to help me tremendously with my calculations.
Finally, a video that doesn't use water as a reference.
This makes sense. Thank you very much.
I had a general understanding of electricity but not the full function of power transfer from a power storage.
Do you have any videos on the difference between 12 - 48v lead acid batteries and so on.
I can really do with that knowledge
Thanks, this is exactly what I'm looking for.
Nice job explaining. One good thing about going in series with 24 volt is wire size. I go for 12 volt and spend more money on wire and save on things that run on 12 volt.
Easy to understand and very well explained even for at total beginner thanks.
I've noticed that some of the all-in-one power units (Bluetti, Ecoflow, etc) are starting to label systems/batteries in watt-hours. Just seems to make more sense and easier to calculate run times or percent usage from power loads.
I find that cheaper brands and cheaper devices tend to rate things in a way to make it more confusing (On purpose). What ever number sounds better to an amateur.
This video really, really helps. Thank you so much for breaking this down like this. I keep having to come back to this video because I forget the formulas. Extremely helpful, thank you!
Excellent video information. Cleared up a few thoughts I was having...
Great tip! The way I remember series v parrell is parrell is not pluse.
Thank you so very much. This really did bless me I’m going to save it. It’s going to take a bit of study for me though. But thanks to your excellent teaching, I’m going to be a lot farther than I was.
Glad it was helpful. Cheers!
Hi, great video, but I didn’t understand why you would use a inverter to convert the voltage from 12V to 120V. Can you clarify? Thanks!
Very good intro/explanation on watt hours. Cheers!
Glad you enjoyed it! Thanks!
good expain and understanble
but I have a question :
why we measure the difference potential to about 400v or 390V or so on in three lines circuit ??
as long as every line have a potential and none of them is neutral
is it must be 0 instead of 400V ?
Thank you! That was very easy to understand.
Huge thanks for this video as I'm using AGMs in series and now I know how much I've got ☺️
Glad it was helpful. Cheers!
Very good I'm as green as a frog in solar newbie you made the simple formula easy for me now to understand what all those and why all those guys said what they did about smaller wires costs down 48v vs 12v thankyou now I know what I need to do to plan my families basic solar unit in Philippines because it's always brownouts for days. Thankyou
Awesome! Glad it helped. Thanks for watching!
Nate, hats off to you. This is the best video I've seen on the subject because of its clarity and simplicity. I just bought 4 new 12V batteries for my semi. I believe they have 100ah each but I'm not sure. So let's assume they do. They use a parallel connection. So I was wondering if you could do a video illustrating WHY semi trucks (as well as other big vehicles) use a parallel connection instead of in a series.
Thank you so much, you just solve a problem for me. This has been confusing me for a while. Your solution is just so great and easy to understand ❤
Awesome! Glad it helped. Thanks for watching!
Nice and thorough explanation. Even after knowing most of this, I did learn something about the gauging of the wires, Thank You.
Glad it was helpful!
arrrrrgg, Math! Great job breaking it down and making it look basic. I'll still need to watch this a few times. Thank you.
No problem. Happy to help! Thanks for watching!
very cool. I am trying to figure out if I can build a battery bank of 4 12 volt batts to b 48 volts. and deliver 1000 watts. so I will have to learn this math at some point. this is the best video I saw so far. but I am not tech savvy. so I ll see if I can pull up more of these
Thank you! - Finally I found a video that explained it well in a easy and straight forward way.
Glad it was helpful. Cheers!
Your way to explain makes me understand easy this formulas that always I was confused . Thank you for sharing this nice content .
Glad it was helpful. Cheers!
So quick follow up question. To calculate total time using the lightbulb example, with the battery not plugged in, you just take the 100ah / 7.81 ah, which would be roughly 12 hours? Is that correct?
great video, I adjusted my inverter and switched to series, and it worked perfectly! thanks !
Glad it helped!
Nice explaination I had to Google everthing and finally went with 24 volt for easy wiring
Darn I couldn't figure it out great explanation but I couldn't figure it out
If I'm going to run a 48 volt system can I run three 300 amp hour batteries12 v and one 200amp hour because that's all I have. Or will that decrease my amp hours immensely because one is only a 200..
. They might all think they're 200
All batteries in one bank should be the same Ah capacity, the same type (chemistry) and ideally from the same manufacturer/model too.
@@jeffnorbert1871 thank you
Great video, this helps allot of people visualize things they need to know.
The "Ah Ha" light is starting to flicker. My old brain is wrestling with this as I am trying to build a system for my teardrop trailer but thanks to your help I am seeing some hope and faint memories of 10th grade electronics class. Thank you.
Hey Buddy, thanks for the Vid. You definitely taught me some stuff & you can explain it better than I can.
I did notice one thing that could of just been an mis-write, in the beginning of the vid there were (2) 12volt parrelled batteries, the positive & negative wires were both wired to one end of the battery bank instead of negative on one end of bank & positive on other end of bank for even/equal current flow.
Thanks again for the video bro!
See any of our full installs videos or wiring diagrams for more info on how to actually wire a battery bank. I also didn't show any lugs, fuses, wire sizes or heat shrink in the 101 level concepts-only video. Don't nit pick me on off-topic stuff like that. 🙂👍
If you were comparing apples to apples, wouldn’t the 25.8v battery powering the light be half the Ah (50)?
Not exactly. The battery amp hours and voltage doesn't change. The battery BANK as a whole is what changes.
Thanks very much. So we really don’t need to know watt hours right? We can just jump straight to how many amps and volts to work out amp hour required. No need to use watt hours at all?
I hesitate to ask such a elementary question, 2560 Wh shown above, does that mean I can run a 100watt lightbulb one hour = 100 Wh divided by 2560 Wh to get time of contiuous use... = 25.6 hours
2560 Wh source capacity ÷ 100watt usage = 25.6 hours of use.
