I have watched dozens of YT videos in my quest to understand not just the advantage of a 24 volt battery, but how that advantage manifests itself across the rest of your entire system. I had planned to use a 4000w inverter just because I wanted to overkill since the difference in the cost was nominal. Finally, a simple video that focused on the details I need to understand. Thanks for sharing. I will be checking out the rest of your videos with high expectations! :)
I found this video for off grid systems, yet the information made me wonder about audio systems that run 10,000 watts on 12 v systems? Thank you for being clear and concise! Great stuff!
From a year ago, doing my first system, I've learned to use several smaller setups instead of trying to run one massive system. Just like your grid power has several lines, I've set up 3 sets of panel-controller-batteries systems, and am very happy with the results. Your video helped my thinking that led to this... Thanks again!!🙌🙌
planecrazyish Good luck!! 👏👏 One thing I did was to use lower power per system, but I bought quality equipment, and didn't buy cheap stuff and defeat the purpose of efficiency.
GOOD IDEA!! Make sure you GROUND those Fckers!! I too have a small 2nd system with a motley crew of leftovers .. 1200 watt on pannels, 4 used AGMs and due to one of the 4 being a bit-O-ch by not charging the same, maintaining a charge.. (it's damaged when I got the 4) I'm forced to use a 12v setup.. .. still.. it's a few hour(s) backup! So rock on!
This is a great video and you explained it very well I’ve been looking at a lot of videos on solar systems and no one has broken down like that. Thank you
Thank you for making this video, so well explained and wish this was the first one that I viewed luckily I have purchased 24v panels . Again thanks for your efforts
I'm reading and trying hard to absorb all the design concepts of off-grid solar. This was simple but it really made a couple of other concepts click for me. Thanks!
Excellent explanation. I did much research and decided to go with a 24 volt system and a 3500 watt inverter. As you said no reputable inverter manufacturer will sell a 4000+ watt 12 volt inverter. Granted, 3500 watts is an overkill for my needs but my system was initially designed for residential use and I have instead repurposed it to power my RV when boon docking. Thanks for this video. I wish I had seen it when building my system. There is not much info out there explaining the benefits of a 24 or 48 volt system. So far, it has served me well. Thanks again for a very informative video.
System planning is the important factor here. My 24V system has a 1kW pure sine LF inverter, 400Ah FLA battery, 1140W of mono solar panels through a 40A MPPT. To draw 1kW takes 40A off my 24V supply, which is 1/10 of its available capacity. In strong sunshine, my battery is at float, so I can draw 1kW from the panels, and the battery stays full. I could draw 2 kW from the system to do laundry in strong sunshine if required, but not at night, so the battery stays happy. (40A from panels, 40A from battery). No heavy loads after dark, only draw big current in full sunlight. My battery is Lead acid, so I try to avoid using more than 15% of it's total capacity, and recharge asap.
nlo114 your 40a controller may be limiting your system to 960w since 40a * 24v = 960w but your stem at 1140w / 24v = 47.5a, which indicates you be using a 50a ( or 60a ) charge controller.
Superb video. You nailed it. I have done tons of research and no one told me so clearly about amp draw relative to volt sizing. Greta job we are indebted to you sir!!!!
Great video as a 35 year electrician you explain it very well, the one thing I would have touch on would be cable sizing I've seen so many videos from so call off grid people using undersize cables on input side of the invertor with no disconnect or fuses, to just plain foolish. Just putting in my 2 cents worth
Edgar Acosta Reminds me of a young man offering his car and battery cables to jump start my 1997 Dodge Ram Passenger van turned camper. Couldn’t get the jump going as his cables were real skinny and probably a drug store $4.95 jumper cable. Pulled out my really thick Home Depot super special cables and connected them and vroom, start up. So, practically speaking thicker cables can make a lot of difference. Don’t ask about my trying to separate a torn sparking wire with a 12 inch screw driver. :)
Edgar, a question I have regarding wire gauges or size is simply can you use oversized wiring just to be safe, or is that frowned upon and let's keep cost out of the decision, just to keep it simple. Thanks for any input you may have but feel no obligation...
@@jackrodgersjr evidently you didn't understand his comment. He stated the very thing you tried to talk trash about! Hilarious! Learn to read before u you make retarded comments.
Great explanation. I just got done watching a video where the guy had 6000watts inverter at 12v....lol....and it wasn't working and he didn't realy know why... I dont want to discourage anyone but people can really get them selves into a dangerous situation. When I started I knew nothing but I read alot and did find information stating I shouldn't exceed 2000w at 12v. And I went from there. Your video explains this very clearly. My advice to anyone now is just skip straight to 48v systems. The components are very good now
wow the autoplay was turned on. I was trying to find this exact answer, watched a bunch of videos and read a bunch of websites with no clear simple answer. gave up was doing paperwork and I hear your voice in the background tell the answer. lol. great video thanks!
That's why I go to 48v system. Back then 3-4 years ago, as a newbie solar energy user, I'm using 12v. Very ineffective power conversion. And then 3 years ago, 'upgraded' to 24v. Seems like better. But now I'm using 48v system. The inverter never get hot as 12v inverter. So I can say it did the job with less 'efforts' for 48v system. Guys, no matter you are newbie or not, it's always best choice to use 48v system for power efficiency and very low power loss conversion by low current. Sorry for my bad english. I'm not english native speaker.
very good example, however the important is that the higher the battery set voltage the higher the incoming charge parameters will be. meaning a longer time to reach the optimal charge input by the array and the controller. be safe, Raz
YOU ARE THE FREAKIN' MAN! Thank you so much for this video! I knew inverter manufacturers were lying through their teeth, I just didn't know how. EVERYONE should see this video! Thanks again!
It all depends on the configuration of your battery bank (for example 4 12v batt with 100A each is quite doable) and also how you derate your design (using a 3k inverter for a 2k application).
I am needing to up grade my inverter and battery bank larger power from a 12v 255 ah batteries and a Aims 1500 watt inverter that couldn't handle running a mini frig and a small fan during summer or small heater in winter. Now that I want to try and connect the A/C that ran off my RV's alternator/batteries system to switch it between that set up onto just solar/battery bank when boon docking off-grid, I have to go bigger. I am so glad I found your video with this very valuable info. on what size of inverter to get for the size of system I should be running appliances etc. while camping off-grid. I wish you had a video explaining the complete system as to what is needed from solar panels needed to to provide energy to the battery bank that would store needed amp hrs. to run either A/C or heater for several hrs. a day and have mini frig/ and computer running at same time. So I learned from your video i need minimum of 24v inverter with a more than 255 ah batt. bank. or and not to mention whether to get or need to change to solar panels that are either 24v or 48v? Do you have suggestion as to being able to buy another 12v, 1500 watt inverter same as one I already have and connecting them together as one 3000 watt inverter? Could it work? to make it a one 24v 3000watt inverter?
Finally someone to break it down simply . Thankyou. I've got a off grid cabin I'm remodeling and making it full off grid. . Power is too expensive to bring in.
Awesome Video !!! And very well explained!!! You taught me a lot!! I have a 12 volt solar system right now...but now after watching your very informative video...I will be switching over to 24v!!
A great video. 245 amps continuous for 3000w at 12.5 v is really on the outer edge of common sense. That would be at least 2/0 gague DC cable. Massive. Great video. This application does not even take into account the 11.x battery drain at the end of the increasing amp draw.
Nice video man. I have a note on your explanation. Amps = watts divided by volts so 2000w inverter divided by 12v equals 166 amps. I have a pv system of 1000w 4 trojan t105re batteries a mppt controller 40 amp and a pure sine inverter 1500 watts on a 12v system. In maximum load 1480watt I consume 123 amps. I have 35 mm square cables that work well. Small systems are on 12v the medium on 24v and the big ones on 48v.
Yep All good .. but you batteries won't last .. You Cook off the water .. Ooh did you just think you can Cook by chardging .. Nop .... It Will also Cook by over using
Let me start by saying, I think the video is informative. I’m somewhat "glad?” I watched it. That aside, this video could be one third as long. Without all the ranting and going over the same thing again and again, it would take less than 3 minutes to get across the point. But I stuck in there, because I didn’t know if there was more toward the end. Nope, just more exasperated restating of the same thing, over and over. Wow.
are there higher volt systems? I have some things that output 600v (like my fuel cell) and am wanting to use that as well as batteries (especially as I cannot find a hydrolizer for the fuel cell which I was planning on having as the main power storage as hydrogen)
I have a 2 64Ah banks of LIFEpo4 of headway cells. It’s installed for caraudio with 2 1/0gauge ofc power cable rated @ 350a each. My alternator is a higher output than stock at 320a. I was thinking of getting a 12v inverter for emergency backup power. I have a eu2000i generator so I was thinking 2kw inverter should be good. What you think? Should I just figure out a way to string 2 batteries for 24v use? Or stick with the 12v system.
I had never truely understand this and so I build the 12v system for my RV. Well, I am running in the same problem you're talking about. As soon as start running the ac along with the fridge and a electric stove my inverter is hot as can be. I have had multiple wires burned up and the list goes on and on. Also, I was under the impression that the high the current the better the system. I would like if you could touch base on is it better to charge your batteries at higher current or lower current. Thank you for your explanation it will help me a lot.
Doing an off grid bus build..... House part of bus is 22 ft long x 84” wide and 6’2” tall in the middle of roof. If we did a 48v system would we have the ability to run a new air conditioner off the inverter? And how much battery capacity would we need?
thanks much for this video, I am really cooked trying to figure these things out, I wish I had studied this stuff as a younger man. Wondering if I can use12 v solar panels @ 100 watts each and 12v batteries and make a 48v system?
I'm building a system for an rv and I'm not sure which voltage system to go with. Which would be best for my needs? I have 1600W fixed panels and can add more as portable panels. Would it be better to go higher V and run everything on ac power or run a converter to drop back to dc power.
What a great video. I’m a beginner and I did not know the higher volts the lower the amp draw. I thought amp draw would be the same due to using the same power draws.
Excellent job. Understood everything. So afraid a 🔥 Even a 48v seam kinda small especially I wanna run my stove or hot water tank. What kind of voltage and amps comes into my regular house ? watts does the average house have at it's disposal??
Question: what about 2 of the 6500 watt all in one MPP solar 48 V solar inverters in parallel both running off the same 48 v battery bank. Can you pull 12,000 watts out of the battery at one time ( each inverter sharing the load 6000 each) or well that be too many amps out of the battery bank at one time?
The invertor is stating wattage from the 115 to 120acv output. 1000w @ 120 = about 8.6amps. There is a reason the 12v dc to 120ac invertor only has a 15 to 20amp fuse and a cigerte lighter plug. Its only supplying 8amps ish to the 115ac device you plug in.
For a load of 1000W working on a 12 volt inverter, the battery must supply more than 83,33A... From the cigarette lighter, being fused with only 15A, the maximum theoretical power to draw cannot be more than 12V*15A=180W...(the losses being excluded)...
Years ago (15) I contacted a guy who did RV solar and told him what I wanted to do. The system he sold me had to be downsized on the draw to 1,000 watts (12 volt). I have an MS3000 inverter with a 7,500watt surge. I used 500lb of Trojan batteries, and was never able to use the system the way I wanted to. This guy was a "Professional"
Will I get more use while my pellet stove run longer instead of feeding my 2000 W inverter with 12 V if I feed it with 2436 or 48 is there an advantage to doing that when my draw is only 300 watch my goal is to try and make the 300 W stove run 24 hours 12 V two batteries I was getting about six hours should I wire it in series to raise that voltage is there an advantage?
*I have been looking for this information all over youtube. Thanks for explaining this. I have one question. If I have a 12-volt labeled inverter can I use 24 volt Battery? Does my battery have to match the inverter input?*
With a 48volt rv system with 200watt panels can i run a wire from the car battery and use a 12v to 48v step up transformer to charge the 48v battery bank?
I’m looking at getting either 4 or 6 350 watt solar panels. Based on what ur saying I should get a 2000 watt Inverter and use 48 volt batteries. Right ? I’m wanting a Limiter also, what would you recommend ?
Question. I've a submersible water pump that I intend to use , Off-grid, every day,. The water pump power rating is 1700w(1.7kw). I also have an array of Solar Panels of 3600w output capacity. I've no need for battery or charge controller, only an Inverter, as I don't need to store energy. I intend to use the power directly on the appliance. What size/capacity of Off-grid Solar Power Inverter do I need to buy. Thank you.
Have you heard anything about 96V lithium batteries that are on offer now? I ran a calculation and it seems like a good option, and from what your saying it will be a safer way to get max power hey?
I have watched dozens of YT videos in my quest to understand not just the advantage of a 24 volt battery, but how that advantage manifests itself across the rest of your entire system. I had planned to use a 4000w inverter just because I wanted to overkill since the difference in the cost was nominal. Finally, a simple video that focused on the details I need to understand. Thanks for sharing. I will be checking out the rest of your videos with high expectations! :)

great presentation, this i understand, thanks, will be looking for your videos on building them, thanks
Good explanation, this is why i use multiple inverters to keep the amp draws as low as i can and any thing 12 volts i run as dc only for me
Do you use one at a time depending on how much you need to draw?
This helped a LOT!. Thank you! :)
FML.
I have a 12v 5,000w inverter.
Thanks for this video
Absolutely the best explanation of the different voltages. Have not seen anything of late from you, hope you are well and look forward to more videos.
It all depends on the configuration of your battery bank (for example 4 12v batt with 100A each is quite doable) and also how you derate your design (using a 3k inverter for a 2k application).

thanks much for this video, I am really cooked trying to figure these things out, I wish I had studied this stuff as a younger man. Wondering if I can use12 v solar panels @ 100 watts each and 12v batteries and make a 48v system?
Great info thank you for sharing
Thank you for explaining that
I'm building a system for an rv and I'm not sure which voltage system to go with. Which would be best for my needs? I have 1600W fixed panels and can add more as portable panels. Would it be better to go higher V and run everything on ac power or run a converter to drop back to dc power.
What a great video. I’m a beginner and I did not know the higher volts the lower the amp draw. I thought amp draw would be the same due to using the same power draws.
Great information.
Excellent job. Understood everything. So afraid a 🔥 Even a 48v seam kinda small especially I wanna run my stove or hot water tank. What kind of voltage and amps comes into my regular house ? watts does the average house have at it's disposal??
Thank you so much for this video. Plain and Simple way to explain all this complexity.
Very usefull information !
Question: what about 2 of the 6500 watt all in one MPP solar 48 V solar inverters in parallel both running off the same 48 v battery bank. Can you pull 12,000 watts out of the battery at one time ( each inverter sharing the load 6000 each) or well that be too many amps out of the battery bank at one time?
excellent explanation.
The invertor is stating wattage from the 115 to 120acv output. 1000w @ 120 = about 8.6amps. There is a reason the 12v dc to 120ac invertor only has a 15 to 20amp fuse and a cigerte lighter plug. Its only supplying 8amps ish to the 115ac device you plug in.
For a load of 1000W working on a 12 volt inverter, the battery must supply more than 83,33A...
From the cigarette lighter, being fused with only 15A, the maximum theoretical power to draw cannot be more than 12V*15A=180W...(the losses being excluded)...
Years ago (15) I contacted a guy who did RV solar and told him what I wanted to do. The system he sold me had to be downsized on the draw to 1,000 watts (12 volt). I have an MS3000 inverter with a 7,500watt surge. I used 500lb of Trojan batteries, and was never able to use the system the way I wanted to. This guy was a "Professional"
Will I get more use while my pellet stove run longer instead of feeding my 2000 W inverter with 12 V if I feed it with 2436 or 48 is there an advantage to doing that when my draw is only 300 watch my goal is to try and make the 300 W stove run 24 hours 12 V two batteries I was getting about six hours should I wire it in series to raise that voltage is there an advantage?
*I have been looking for this information all over youtube. Thanks for explaining this. I have one question. If I have a 12-volt labeled inverter can I use 24 volt Battery? Does my battery have to match the inverter input?*
With a 48volt rv system with 200watt panels can i run a wire from the car battery and use a 12v to 48v step up transformer to charge the 48v battery bank?
thate was great video
thanx for the vid! isn't it true that you can run 12v batteries in series to achieve a 24v power supply for a 24v inverter? thanks

I’m looking at getting either 4 or 6 350 watt solar panels. Based on what ur saying I should get a 2000 watt Inverter and use 48 volt batteries. Right ? I’m wanting a Limiter also, what would you recommend ?
Question. I've a submersible water pump that I intend to use , Off-grid, every day,. The water pump power rating is 1700w(1.7kw). I also have an array of Solar Panels of 3600w output capacity. I've no need for battery or charge controller, only an Inverter, as I don't need to store energy. I intend to use the power directly on the appliance. What size/capacity of Off-grid Solar Power Inverter do I need to buy. Thank you.
Have you heard anything about 96V lithium batteries that are on offer now? I ran a calculation and it seems like a good option, and from what your saying it will be a safer way to get max power hey?
