The Ultimate Van Build Journey:
In Season 1 of the van build, we stripped off the old DPD stickers, rust-proofed the entire van, painted it our favorite matte grey color, redesigned the cab, planned our van's design / layout, created our epic water tanks, built our custom panorama roof windows, installed new wheels, & installed an insulated floor! PHEW! Building a home is something else! bit.ly/LM_SEASON1
Then Season 2 of the van build rolled around, and with our workshop's renovation behind us, it got TECHNICAL! We built a 47 degree solar tilt (1kW of solar power!), made custom seat bases & installed our custom seats, we took security to the NEXT level, breaking down our 12 incredible layers of security, wired everything our tech-dependent home will need, created the BEST insulation we've ever seen in a campervan (check out our video on campervan insulation & cold camping insulation), installed our own custom security cameras, framed the ceiling, AND created our peak-a-boo curtains. WOW!! We are beyond ready to be off grid in this Ducato van home! ❤️ bit.ly/LM_SEASON2
Now Season 3 of the Van Build is kicking off in our brand new space, allowing us to work regardless of the weather or time of day! This is going to be the most exciting phase of this van life build yet!! bit.ly/LM_SEASON3

🐾 Who are we?
We’re Ladi (from Czechia) & Margaret (from USA) and we love eBikes, campervans, & cats. In 2020 our van life lifestyle flipped upside down, & we needed to stop traveling in our camper to lockdown in eastern Czech Republic due to the pandemic. With no travel plans and some new time on our hands, we decided to sell our old van, start an electric bike business, begin a youtube channel, build our ultimate dream campervan, renovate a junkyard into a tiny house homestead, plan a container & upper workshop space… well, some other smaller projects in-between 😅.
What we thought would only be 6 months of “stillness” has become 2 years of innovation, progress, and so much fun, and most of that is thanks to YOU. Although we’re excited to be back on the road and traveling the world again soon, we’re so thankful to lay a foundation here in Central Europe & bring you with us on this crazy journey. Thank you for supporting us and being part of this incredible community!

just catching up on this vid, perhaps to test the controller and principle - drop a panel from the series and check the controller with just 3. this should keep voltage under and allow you to test your premise before replacing the controller with a 150v version. hope you get the satisfaction of seeing it running soon!!

@p_mouse8676 Жыл бұрын

I saw that the whole battery pack is hold down with an aluminum bar with some bolts directly onto the chassis at 12:40. In theory this would create a problem with galvanic corrosion, especially when these is humidity/water involved (from the bottom of the van). Time will tell if this practically really creates a problem, but it is certainly something to keep an eye on! Especially when you use that bar as a ground as well! About the solar panels, yeah that is a bummer. Rule of thumb is always use doubles series + parallel for a 48V system, or swap to a 24V system instead. Really nice build though!!

I’ve seen this in n my solar controller and it took me a while to realize the decrease in wattage is part of the smart controller. You can charge at a higher wattage but as the batteries charge or reach full charge the smart solar controller will taper off how much power it is allowing in. If you discharge your batteries 10% or so you will likely see much higher wattage because the solar controller is going to allow the maximum amount of wattage in to convert that to a charge.

@vanDeudekom Жыл бұрын

Yep that sounds like a possabillity to me.

Hey Ladi, really surprised that you made a 'schoolboy error' because your attention to detail is always impeccable.

In the past I have used a similar capacity using 4 panels, but used EPEVER Tracer 30A controllers on each panel.

Can your solar panels be stopped at different angles? Or is it always flat on top or tilted at one angle? Do you have an easy way to figure out how much it needs to be tilted? The reason I ask is it seems like being tilted too far can be as bad as being flat on top of the roof. You've done great being able to tilt it. I'm sure your phone can tell you which way South is. It would be even nicer if your tilt system could follow the path of the sun as it travels through the sky. (But to be honest, I think I've only seen Solar Power farms do that. I'm not sure.)

I run that same MPPT Controller ( Victron 100/20 ) on a 210 watt panel feeding a 200Ah AGM Battery bank. I also run ( 3 ) Victron 100/30 MPPT Controllers feeding 400Ah of LiPo4 Batteries. The next issue you will have is getting a larger MPPT Controller to fit in that small area of the current controller. Good luck. ** If you click on my name you can see a small idea of my power wall.**

Most electrical components can be run at +/- 10% of ratings. Not recommending this approach but it sounded like you were close enough for a brief test. Also, couldn’t you have covered a portion of the solar panel(s) to test the system?

Good idea, I could have covered a panel or a quick test! The worst would be if I spent money for a new controller even tho the old one would do the job.

Hi. Your low Watt reading might be due to almost fully charged batteries. If they are close to fully charged, the Watts are getting very low. Thats "normal". I am sure you already considered that. Good luck.

Hi, they were in nominal voltage. That was definitely not the reason of low solar charge.

@@ladiandmargaret with mppt victron you have to add load to the system if the batteries are fully charged and there is no load the mppt solar charger will go to float mode that is he will only provide little power to the system. Try to connect something which consumes high amps you will see the watts and amps flowing from the roof!

I wouldn’t beat yourself up about the solar panels and the charge controller. It’s taking me a long time to learn and I still am not very good at the math. You have more than enough power there for a house, so I’m curious to what you’re going to use all that power for in a van.
