Ladi, you are a beast! Thanks for giving us the update / keeping your fans informed. Dude, you may have just switched my current build from 24v to 48volt. Can't wait to see the breakdown for electrical.
I have been looking for a48v system for so long and i even went to several US expos and learned so much. I’ve even outlined and wrote down everything. You are the first to actually do it and I’m so happy i found you two!!!!
I knew your electrical system would be over the top but this exceeded anything I could think of. I can't wait to see what batteries you're using and to see the whole thing in use.
You have no idea what a relief it is to know that a whiz-kid like you has reached a point where uncertainty is a big issue. I thought you had ALL the answers!! Now I don't feel so bad about so many uncertainties in my own build. I think this is like when a child finds out his parents are human :D
Hi Ladi, this is one of your best, in terms of inspiring and engaging, videos. You are an awesome couple. Each of you is relatable in a unique way. As someone also mentioned you have made complex electronic systems understandable. I couldn't do what you've achieved but you encourage me to be less afraid of trying to understand and install simple electronic system in a small van. I like the way you share the experience of your previous cling film wrapped, eretractable extension cable. Keep up the good work. I'm looking forward the next video with you both.
Good decision to prefer a 48 VDC system and great installation job too. The only thing I would choose is a Microwave inverter oven (Panasonic example). I have one at home and can never live without it. The time for cooking can be reduced significantly. The program for pizza (frozen too) is just perfect. Convection, turbo bake and grill are doing a good job too, you just need to find the correct settings over time. I will never build a camper, but it is exciting to follow your handcraft and skills, which can be adapted even in the house. Keep going. 👍🤘
Truly impressive setup! But I'm somewhat confused on your conversion for the 12V system comparison: Wouldn't this correspond to 1100Ah (rather than the 6500Ah you're saying in the video)? This would not quite add up in terms of weight (our 400Ah 12V system weighs around 45kg)...
I thought the same. It is a pain to convert for the less electrically minded like myself, however I have a 48V 15.4kWh system and by my reckoning that's 1200Ah @ 12V
Ladi, absolutely love you! love the videos. Electrician here. Please make sure your system is wired for 3 phase if you're going to be using more than 1 phase. If the phases connect/touch, you'll get a huge surprise and probably end up in hospital. So, please be careful.
Wow Ladi… I dint understand lots of what you were talking about cause I’m not mechanically minded! But I was amazed that there was something besides 12 and 24 volt! I really loved the compact kitchen and the oven! I can do without microwave but I need an oven too! I really appreciated the space saving you have in this cabinet! Thank I’ll keep watching! Love you guys!
I have a few project where the 48V battery is charged from the 12V car system. A dual alternator is challenging ( awkward mounting, double wiring, load control ), however upgrading the existing 12V to a higher current one is often more feasible / easier. In those systems I used a Calex bidirectional controller ( 48S12.3K0BCA ) ( wicht allows many fun stuf because of its bidirectional features, like using high power 12V stuff from the energy of the 48V system), that controller allows to charge the 48V system from 12V alternator power. This controller, with some use of an external controller, allows similar things as the Scotty bidirectional converter from Safiery ( they have many videos, to get an impression of what it does ).
Hey Danny, this was very interesting to me because I was looking for the same thing. The best I came across was the Sterling BB1248120 12-48 which isn't even released until Q1/Q2 of 2023 and is 1500w output. Yours is 3000w output? I found the Calex one for sale for $775, is this about right? Already it is $150 cheaper than the Sterling one and double the wattage? :S. I was thinking to upgrade my 150A alternator to 280A, though that will cost $1k. What size alternator do you have? and how have you found it charging so far? What is your real world input/output? Can you throttle the input/output so you're not overdrawing from your alternator? I think this is the only semi-realistic approach as a 48v alternator is $$$$$$. Also what is the external controller you're using?
I love your approach regarding 48V and distribution of weight! When it comes to ways of charging: On top of the price for alternator ++ comes the price of actually charging, using expensive gasoline/diesel as source of energy. Not cheap. Something to avoid if you can. May the sun be with you!😎
You made a good choice. I fell for all the reviews from TH-camrs who got a Bluetti in exchange for a favourable review. I would not gift the Bluetti I bought to my worst enemy. I don’t hate anyone that much.
That’s was great. I didn’t understand everything but you sure have me convinced. Ladi you are so smart I like listening to you talk. You guys are ready for the start of the apocalypse.
I'd check with a qualified electrical engineer on using 3-phase the way you describe. In my industrial-technician phase/career we were warned to not unbalance a three-phase system the way you describe.
Awsome work! Im setting up a 48v system for the same reasons as you running from 4 x 300ah 12v batteries, Victron do a 12/24 step up to 48v battery to battery charger which can run from a second alternator.
I don't know what BMS you have, but I would recommend putting a monitoring system in place. There is a VenusOS (by Victron) driver out there that can monitor and log many of the popular BMS brands. My advise would be to go straight for the Cerbo GX. You will thank yourself later
I think 24v is the sweet spot because you can find lighting, outlets, and appliances in 24v to run without voltage conversion inefficiencies and still save on wiring compared to 12v. My Dometic fridge and LED lights which consume the vast majority of power on a daily basis are 24v.
Thanks for the electric system details! Were you able to find 48V lights? What about USB charging? What power is running your overhead fans? I missed you talking about or showing a step-down unit for these smaller appliances.
I saw a guy use cheap 12-48v step up converter to boost his alternator voltage to 48v and then fed that to an MPPT controller to charge batteries. He wired 4x (300w) in parallel which required balancing resistors and diodes to make converters work together, he uses this to charge 24v system
Wow! Fascinating stuff you’re doing. I think I even understood much of the discussion of power. I like how you are focusing on systems as a whole like this. I love watching creative moments happen, those aha! Moments. Thanks for sharing your knowledge and wisdom. I wish I could offer you insights on the alternate alternator. I’m sure with enough crowd sourcing, research and pondering you’ll find the answer.
I wish you were getting paid big bucks from RV industry leaders for all this free consulting! You’d deserve it! Although today’s vid was all over my head, I really enjoyed it! I love creative, imaginative smart thinkers who share and seek knowledge & creativity in return = how the world should be! 😊
cars in music competitions occasionally use multiple generators, 24v is used by heavy-duty machines, tractors, trucks. I myself have seen three 12v generators on a passenger car.
Best not to try and add another alternator to the existing serpentine belt system if it's not possible to do so without adding any additional lateral pressure to the bearings of the other components (a/c, engine water pump etc). If possible, use an additional belt running off a double pulley for the non-essential alternator so if there are any issues with it you're still mobile. And it goes without saying, always carry spare belts. They're light and priceless when you need them! Keep up the awesome work 👍
Great Video as always. Meanwhile, Who else noticed there was no regular intro and outro just straight up to the deed of the day. I had to restart the video after it ended to be sure it wasn't my imagination.
Thanks Alaye. We are absolutely crazy busy and overworked so we decided not to publish this Sunday. This video was my last minute decision so I’m sorry for downgrading editing standards on this channel. Hopefully information value compensates a bit.
@@ladiandmargaret I loved the video regardless. It was packed with valuable information. Well done guys. I always personally look forward to your Sunday Uploads...
As an electrician I'm in pain... running 3 different phases via CEE7/4 or CEE7/7 in a 5-wire-cord (L1/L2/L3/N/PE) is very dangerous, there are sockets (outise czechia) with an indefinite L/N behaviorso you can't just plug 3 CEE7/4 or CEE7/7 easy together
Great video 👍 I think your system is so ahead of any other in vehicle system out they.If a second alternator is used maybe a modified one with a air conditioner drive pulley which has an electric clutch on the pulley output controlled by an Arduino.
Thanks for another cool video and technical explanation. I have been back and forth with my electrical system, one 48 V system or separate 48 and 12 V systems or just a 12 v system. My reasoning has been similar to yours, cheaper 230 VAC apliances and just necessary 12 VDC (like lights ans some 12 VDC sockets - even water pump could be 230 VAC). Only problem with this is the need of a 48/12 VDC converter and the efficiency of it, but as long as the load on those 12 VDC circuits is low it should not be a deal breaker.
Ladi: some advice on the compressor fridge. Those things are VERY loud, especially because they jump on at night. The only reason why I still prefer Gas!
Will we be getting detailed video of all the things shown above? Cause i am waiting 🥴🔥 Your videos are too good And i feel motivated to do things 🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥
Muito legal! Estou tambem montando um sistema 48V no nosso trailer (onde moramos eu, minha companheira, a nossa filha de 2 anos e nossas duas gatinhas). Sua instalação ficou linda, muito bem feita!! Também estou preocupado com a potência de recarga das baterias, para poder recarregar em estações de carga de veículos elétricos. Não valeria a pena você ter usado o inversor/carregador MultiPlus-II de 5kVA, no lugar desse inversor de 3kVA? Porque o MultiPlus-II de 5kVA já tem uma potência de carregamento de mais de 3,5kW, pois tem corrente de carregamento de 70A...
Sick setup!!!!! Look forward to more detailed video on your water systems, and electrical systems. I wish you guys could do a solar system educational video, explaining the systems , but with Your Ladi and Margaret comedy. Would be sweet. Thanks for what you do. Your both geniuses!!! Have a blessed week.
Thanks a lot. Some topics are well covered on youtube already. We could do such video but maybe when we actually live in the van and have more spare time.
Ladi its an amazing set up and woww well done its off the grid with design, BUT you are missing one thing CAMP sites only normally give you 6-8amps if you are lucky, with the power draw you are asking it will keep tripping the camp sites electric. So you will be relying on sola DC to DC to keep the batteries charged. Or just charge the batteries with the 6-8 amps. Is this somthing you have thought about. Love the design and how its coming together, 👍 michael UK
I don't know the specifics, but I know my late brother started a welding business with a homemade welder. His welder consisted of a bracket and separate (manual engage/disengage) serpentine belt to run 5 extra alternators on his old F-150. RPM's controlled by a brick on accelerator pedal. We called him the red neck McGyver!!LOL!!
You should take a look at Balmar. They make alternators specifically for the second alternator use case. They have a 48V alternator system and provide better serpentine belts etc.
Check out the Killer Wasp from Safiery in Australia. It will take the 12v from your existing alternator and charge your 48v battery bank. It can draw up to 1000w from your existing alternator
Ladi, I have a question young man... regarding the toaster oven.... did you line the interior of the cabinet housing with steel or anything as a heat protector from the oven? I noticed you place vents on the side.... I am guessing they are lined up with the ovens venting ports... will those exterior vent ports be enough to vent the heat from the oven, considering its in a fixed tight spot and those ovens generally need space... I would like to do something similar as opposed to having to pull it out and place on the counter top and wait to cool before putting away... Thanks so much! My best Randolph
Awesome build, I’ve been running a home built 48v 20kwh battery pack system at my house charging from a 6kw solar system for the past year. As a suggestion you could utilise the 3phase sockets on the extension real and make up adapters to utilise the phases you have available e.g 1phase plug wired to the phase you on the 3phase socket outlet you want to use or even make up an adapter box between the plug and socket with a selector switch to chose the phase you want to power up. You then would require less wiring in the van. I would also suggest to fully unwind the extension to eliminate excess heat build up in the cable when running near the cable amp rating.
It should be unwound way before, though there are a lot of variables, but better safe than sorry, I would personally unwind at about third of the rating at the latest. Some extension reels have a label which has the safe wattage/amperage which is nice.
I love the design of your power setup. Be careful though with the 3phase input. Don’t try to put 3 house plugs as plugs. If you plug in one of them the wrong way you have 400v going into your system! You should rather have one main phase you wanna use all the the time and maybe some switching in the back to decide how you distribute it.
Forgive me I've only just stumbled across your video. But at time 3:49 in your video your showing your distribution blocks. Might you know the AIC (amps interrupt capacity) of these particular fuses? Are they rated to break a 48VDC nominal ark? Again I'm not trying to be confrontational or rude; just wanted to ask so everyone is as safe as possible (I've seen to many use standard automotive fuses that will cause fires & not act as true rated fusible disconnects). All the best to you and your van build 😊👍. Thanks for sharing!
Good question. The pack seemed to be better configuration to fit my space and series are much easier to upgrade. I think the inverter stops working at 36V so having 14s would be more suitable for sure.
a fwd van with a long wheelbase and a heavy rear axle load. Q. Have you ever thought how good it would be to use benefit of your 48v electrical capacity to provide the option to drive an electrical motor to gain traction from those heavy loaded rear tyres?
That is a very bad idea. I would need much higher output, gain a lot of weight, complicate the system with a lot of modifications. Nobody would ever see this as a good idea to do.
@@ladiandmargaret - output depends upon on the power requirement of the motor, namely the peak Amps draw, at 48v this would reasonable until 15kW. The purpose of the drive system is auxiliary for recovery purpose at zero and low vehicle speeds so Torque (traction at wheels) not horsepower is the requirement. - Weight and complication - yes for sure 4x4 costs - take a look under a Sprinter 4x4 transmission system, check the additional component assembly weights (transfer case, low range gear and 2nd axle differential and driveshafts. circa 150kg) - and the cost$$ of replacing an existing promaster with a 4x4 sprinter or an AWD-Transit. -Nobody would ever see this a good idea? > it is called P4-thru-the-road-hybrid, the auto industry has been playing with it for 30years and Toyota has demonstrated it can provide highly effective offroad capability in a hybrid, nonetheless the size of market from an OEM perspective has always been limited, but the market is changing dramatically with EV, yet BEV alone on a heavy Van/RV is a long way out of the horizon of existing van-life promaster owners. Especially those who do wish to push their vans into more adventurous parking location where a 4x4 feature would be distinctly an advantage.
@@ladiandmargaret I thought that you asked how to charge 48v bank from 12v alternator... Please correct me if i am mistaken. The question would be what algorithms your chargers are using..?
Remember to run the fridge for 3 days with a wattmeter so you know exactly what is the wattage as well know when it runs the defrost flow as thats’s when it gets more watts, let us know the result 😁
Hey was wondering if you make or know a good company that will custom make a conversation van. I know exactly what I want just need someone with the know how.
hello watched someone with a vw T5, he put the socket behind the bit of plastic under the rear lights and put a hinge on it, when closed socket is hidden, open when you need to use it
You might want to check out another youtube channel "sailing sophisticated lady" and a recent episode. They just installed a 48volt generator to their new boat engine, and switched over to 48volts. They also have solar and a massive batterybank from battleborn brand.
@@ladiandmargaret Similarly, "Odd Life Crafting" just got a WS500 Advanced Alternator Regulator from Wakespeed for their boat. How about adding a Super capacitor and regen, when you are not too busy🙂🚐☢
Hey guys, been looking at your cyberbike and wondering if you will be charging yours off the house batteries or just off campsite power inlets? (apologies for lack of technical lingo and if you have mentioned this already).
Ladi, you are a beast! Thanks for giving us the update / keeping your fans informed. Dude, you may have just switched my current build from 24v to 48volt. Can't wait to see the breakdown for electrical.
I have been looking for a48v system for so long and i even went to several US expos and learned so much. I’ve even outlined and wrote down everything. You are the first to actually do it and I’m so happy i found you two!!!!
Ladi you excel more and more in each video, it really is amazing watching how you brain works, you really are blowing this van building world apart
Super informative video! Usually when people talk electrical I feel like they’re speaking Klingon but Ladi makes it make so much sense.
Děkuji moc, člověk se hodně technický posouvá
I knew your electrical system would be over the top but this exceeded anything I could think of. I can't wait to see what batteries you're using and to see the whole thing in use.

Have a blessed week.
Thanks a lot. Some topics are well covered on youtube already. We could do such video but maybe when we actually live in the van and have more spare time.
Ladi its an amazing set up and woww well done its off the grid with design, BUT you are missing one thing CAMP sites only normally give you 6-8amps if you are lucky, with the power draw you are asking it will keep tripping the camp sites electric. So you will be relying on sola DC to DC to keep the batteries charged. Or just charge the batteries with the 6-8 amps. Is this somthing you have thought about. Love the design and how its coming together, 👍 michael UK
I don't know the specifics, but I know my late brother started a welding business with a homemade welder. His welder consisted of a bracket and separate (manual engage/disengage) serpentine belt to run 5 extra alternators on his old F-150. RPM's controlled by a brick on accelerator pedal. We called him the red neck McGyver!!LOL!!
Great Video. Thanks Ladi. What fridge do you have? Best regards from Switzerland, Silvano
What kind of AC/DC battery charger is this? Love your setup! thx!
This guy is a frickn Genius!!!
Great Job Ladi , 48Volt system is way more efficient than 24 or 12 vollt system.
Wow, you are going for it!!
You should take a look at Balmar. They make alternators specifically for the second alternator use case. They have a 48V alternator system and provide better serpentine belts etc.
I know but they are crazy expensive.
@@ladiandmargaret that they are. Boaters are rich :D
I got it now, that’s why 😂
Check out the Killer Wasp from Safiery in Australia. It will take the 12v from your existing alternator and charge your 48v battery bank. It can draw up to 1000w from your existing alternator
I’m after 3kW alternator and ideally higher voltage. Conversion like this would be less efficient and I would need much bigger wires.
Try the safiery Scotty. Rated at 3kw. It’s an awesome piece of kit.
It’s crazy expensive.
Indeed 48 Volts is the way to go. It is the maximum voltage to still be safe!
48 isn't safe anymore
Ladi, I have a question young man...
regarding the toaster oven.... did you line the interior of the cabinet housing with steel or anything as a heat protector from the oven? I noticed you place vents on the side.... I am guessing they are lined up with the ovens venting ports... will those exterior vent ports be enough to vent the heat from the oven, considering its in a fixed tight spot and those ovens generally need space... I would like to do something similar as opposed to having to pull it out and place on the counter top and wait to cool before putting away...
Thanks so much!
My best
Randolph
Awesome build, I’ve been running a home built 48v 20kwh battery pack system at my house charging from a 6kw solar system for the past year. As a suggestion you could utilise the 3phase sockets on the extension real and make up adapters to utilise the phases you have available e.g 1phase plug wired to the phase you on the 3phase socket outlet you want to use or even make up an adapter box between the plug and socket with a selector switch to chose the phase you want to power up. You then would require less wiring in the van. I would also suggest to fully unwind the extension to eliminate excess heat build up in the cable when running near the cable amp rating.
It should be unwound way before, though there are a lot of variables, but better safe than sorry, I would personally unwind at about third of the rating at the latest. Some extension reels have a label which has the safe wattage/amperage which is nice.
@@VilmaHallikas fully agree, def way to much variables so the safest bet would be to fully unwind before every use!👍🏻
Definitely!
I love the design of your power setup. Be careful though with the 3phase input. Don’t try to put 3 house plugs as plugs. If you plug in one of them the wrong way you have 400v going into your system! You should rather have one main phase you wanna use all the the time and maybe some switching in the back to decide how you distribute it.
Thank you for the input, I’ll consider.
you're the man brother
HI. There is a van manufacture in Australia that uses the 48V system. Kimberley. 👌
do you have a build list of items for the 48v solar.
Epic setup!
Forgive me I've only just stumbled across your video. But at time 3:49 in your video your showing your distribution blocks. Might you know the AIC (amps interrupt capacity) of these particular fuses? Are they rated to break a 48VDC nominal ark? Again I'm not trying to be confrontational or rude; just wanted to ask so everyone is as safe as possible (I've seen to many use standard automotive fuses that will cause fires & not act as true rated fusible disconnects). All the best to you and your van build 😊👍. Thanks for sharing!
Confused about the 6,500 Ah @ 12v. Isn't it ~1,200? I have a single 400A 12v battery which is 5,120w. This is awesome, though
You are right, my mistake.
An alternator setup for 48v charging is using a dedicated 2nd alternator with an external voltage regulator to step up to 48v output.
There are 48v alternator out there. Stepping it up is an option too.
48 Volt alternators are very common in the marine industry, looking at $1200-1500. 48V/200amp
Thanks... yet another great video :)
What are your thoughts on server rack 48v 100ah batteries with an all-in-one solar charger inverter (EG4, by signature solar)?
Looks pretty.
Sounds good.
I'm not a fan of the Phoenix.
And, in the US, running 120, I'd not set my system up like that.
So funny when you say. this is pretty much my simple setup. hahaha. but amazing work
Why did you configure the battery for that lower than normal voltage? Will the victron inverter still make AC power at 36 volts?
Good question. The pack seemed to be better configuration to fit my space and series are much easier to upgrade. I think the inverter stops working at 36V so having 14s would be more suitable for sure.
Totally epic
a fwd van with a long wheelbase and a heavy rear axle load. Q. Have you ever thought how good it would be to use benefit of your 48v electrical capacity to provide the option to drive an electrical motor to gain traction from those heavy loaded rear tyres?
That is a very bad idea. I would need much higher output, gain a lot of weight, complicate the system with a lot of modifications. Nobody would ever see this as a good idea to do.
@@ladiandmargaret - output depends upon on the power requirement of the motor, namely the peak Amps draw, at 48v this would reasonable until 15kW. The purpose of the drive system is auxiliary for recovery purpose at zero and low vehicle speeds so Torque (traction at wheels) not horsepower is the requirement.
- Weight and complication - yes for sure 4x4 costs - take a look under a Sprinter 4x4 transmission system, check the additional component assembly weights (transfer case, low range gear and 2nd axle differential and driveshafts. circa 150kg) - and the cost$$ of replacing an existing promaster with a 4x4 sprinter or an AWD-Transit.
-Nobody would ever see this a good idea? > it is called P4-thru-the-road-hybrid, the auto industry has been playing with it for 30years and Toyota has demonstrated it can provide highly effective offroad capability in a hybrid, nonetheless the size of market from an OEM perspective has always been limited, but the market is changing dramatically with EV, yet BEV alone on a heavy Van/RV is a long way out of the horizon of existing van-life promaster owners. Especially those who do wish to push their vans into more adventurous parking location where a 4x4 feature would be distinctly an advantage.
What about 12v to 24v DC to DC two chargers connected in series...? Victron Orion-Tr Smart 12/24
But why?
@@ladiandmargaret I thought that you asked how to charge 48v bank from 12v alternator... Please correct me if i am mistaken.
The question would be what algorithms your chargers are using..?
I have no experience with 3 phase, when you plug in one phase into a domestic system, are the remaining two unused plugs not made live in any way?
Finally a question why use an oven and not an air fryer - that can fry, bake, roast and reheat?
omg! This system is mind blowing! Can this Electric Car Charging adapter also be used to plugin in „regular“ Campervans? Where can i buy this adapter?
It can! I made it.
Remember to run the fridge for 3 days with a wattmeter so you know exactly what is the wattage as well know when it runs the defrost flow as thats’s when it gets more watts, let us know the result 😁
Hey was wondering if you make or know a good company that will custom make a conversation van.
I know exactly what I want just need someone with the know how.
hello watched someone with a vw T5, he put the socket behind the bit of plastic under the rear lights and put a hinge on it, when closed socket is hidden, open when you need to use it
Great explanation👍
Also in 24v or 48v system do not use 12v batteries (BMS's will get out of balance). When comes to 24v/48v system use only 24v/48v batteries.
What are you talking about? You can have four 12v batteries in series that gives you 48V system! Or in my case using 12x 4,2V batteries with bms..
You might want to check out another youtube channel "sailing sophisticated lady" and a recent episode.
They just installed a 48volt generator to their new boat engine, and switched over to 48volts.
They also have solar and a massive batterybank from battleborn brand.
Thanks. I actually know this alternator brand. They are very expensive and controllers are around $2000. That’s too much for electricity generator.
@@ladiandmargaret Similarly, "Odd Life Crafting" just got a WS500 Advanced Alternator Regulator from Wakespeed for their boat. How about adding a Super capacitor and regen, when you are not too busy🙂🚐☢
Hey guys, been looking at your cyberbike and wondering if you will be charging yours off the house batteries or just off campsite power inlets? (apologies for lack of technical lingo and if you have mentioned this already).
I had been contemplating the same for last 6 months.
...glad to know that I'm not the only one who needs a 3D printer on my rig. (Print-a-Part)...
Are you certain this is the smallest possible profile you can come up with for the power? Feels like you could hide is a bit more
