Hi. We have a sailboat with two solar panels, one is 380 watts and the other 135 watts. Our battery bank have 315 ah. We use a induction stove, electrical coffee maker, TV and sometimes a fan on 127 volts. It is working fine, but we live in Brazil at 8° of latitude south with plenty of sunlight. Keep going and you will make it works 👍
I don't know your complete design, but I was surprised that you plan to mount the batteries near the wheels instead of toward the trailer tongue. Optimizing the weight distribution and the space utilization can get complicated.
I was a little surprised to see you completely cut the side rails off your trailer. Thoes do provide a good bit of strength to the trailer. I'm sure you have a plan to restore that structure in the build but if not, you might consider it.
It will be interesting to see the protective cases/under trailer protection for the batteries. Putting them below the floor will save space but will make them much easier to damage from road debris flying up. I know when we were kids that the camper we had used a heavy duty metal frame for under the battery and it was also protected by the tongue/frame. Interesting video on the electronics :)
Your setup is very thought out and looks good. In fact, it is nearly the same as what I am building. Most go with a 12v setup like yours, I am going with a 24v as it is more efficient and cheaper to build. For example, wiring must be somewhat expensive for your 12v system, 24v wire size can be reduced significantly. I like your setup with the charge controllers too. But again, with a 24v system you can save as the size can be reduced by half, and only one charge controller. Seems your batteries are a good choice, do not know much about them. Good Job! You might want to consider and all-in-one system. Saves space in your teardrop, and they have been around for awhile also. Checkout if you want MPPsolar or Growatt. I am going to go with MPPsolar 24v with 2700-watt inverter, doing this to save space in my trailer. In fact, they are even cheaper to build with and can work just as well.
Wow that is quite a system, sounds super complicated to me and since I am basically clueless about such things (I have soldered a few small cooling fans and Led lights but nothing on this scale. BUt looks and sounds good and hope it all works out and fits into your space
I am very interested in getting my workshop 'off grid'. Currently have a simple setup of a 100w panel, 12v car battery and solar controller. Plan is to charge my cordless batteries via solar. Could or can you charge them via 12v rather than using an inverter?
Pretty interesting system indeed, Linn! 😃 It's looking great! Stay safe there with your family! 🖖😊 BTW, search for Tessa tape. It's a kind of isolation tape, but it's made of a fabric... It's commonly used for cars, because it really protects the wires!
I want to do solar in my shed for lights and maybe have the ability to run some tools. My shed doesn't have power so that's why I thought solar power would be a good option.
There's a channel, Solar Solution, that is great for leaning the off-grid power bits and pieces. This German engineer's videos are short on each element and now taken from his Udemy course. Charge controllers, voltage drop in wires, generators, battery types, with cost/power comparisons.
May I suggest getting 2 inverters? this will create the same redundancy your system has built In already (2 of everything). Inverters just like all these components can fail, and with only the 1, you would be out camping without power.
always make sure that your panel made by flammable board. when mosfets start to burn your board gonna burn and all garage will be ash good good anyway maybe good practice is use PTFE panel
Hey Darbin, always interesting stuff. You should contact Will Prowse who does a lot on these type of DIY solar systems and he could help you set up the coolest system.
Excelente video, muy bien explicado y muy didáctico, saludos desde Torreón, Coahila, México. Comarca Lagunera donde tenemos muchos dias de sol y este tipo de proyectos nos vendria bien implementarlos.
Your wire size discussion isn't totally correct, if you would have put the 3 panels in series you would step up the voltage but not affect the current on the input side and would have saved A LOT or wire, not needing to extend each panel back to that Y connector or even have that Y connector. My understanding on panels connected without a DC optimizer is any one panel that is shaded still pulls the other panels down and affects the output of that entire string.
@@darbinorvar Thanks. I looked into shading more and yes, having the panels in parallel does protect you in that case, This video was very good at showing this, in the video she shades a row of cells within a panel but that's essentially the same as a parallel panel. th-cam.com/video/QzzB1i1w_kM/w-d-xo.html
Solar panels are brilliant when sun is available. But what will you do when there is no sun shining? Volcanic eruptions can block the atmosphere for days or months. When there is a big enough eruption it could block the sun for years. Then there will be no sun or wind. What if you could just plug in to the earth wherever you are and extract energy from this giant earth sized capacitor? When you can do that, then you will not have any limitations.

Reaction to 2 points evident in the video - It lacks cover on bus bar. That can be dangerous when amperé strength is large enough. Experience with Lifepo4 batteries is that they are much more stable than lead/acid versions. Think it's overkill with 2 pcs of 200ah Lifepo4 batteries - but it depends on the consumption and how often the comsumption is ON. Flexible panels doesn't last very long. I use frame panels with glass front on the cabin, more than one test has shown that flexible panels are out of business after a year or two - depending on the sun angle and how clean the local air is. - How long does it take to charge the batteries to at least 80% - how many panels and hours is needed? Weather changes over time suggests around 40% to 50% of max capacity on the panels. For norwegian readers- utdrag fra Sunwind; www.sunwind.no/pages/tips/read/?id=49

Whoa incredible stuff! Question, is thus how most wardroom trailers are posted? Are the ever powered by the tow vehicle? Thank you.

Love the setup Darbin!!

Thanks for the explainer. Solar is pretty amazing. I’m interested in setting up a solar back up for emergencies, particularly post hurricanes.
Wow that is quite a system, sounds super complicated to me and since I am basically clueless about such things (I have soldered a few small cooling fans and Led lights but nothing on this scale. BUt looks and sounds good and hope it all works out and fits into your space
Looks great Darbin, much better! this will let you cook for a long time.
Thanks for sharing those tips, good luck!
batteries near the wheels is well placed, but do not forget to easy access for maintenance in other way, it will be super! keep going

Did you ever build the teardrop??
it's on hold for a while
I want to do solar in my shed for lights and maybe have the ability to run some tools. My shed doesn't have power so that's why I thought solar power would be a good option.
When I go camping I bring a headlamp and an extra pair of batteries, done. 😎

interesting prototype, though more complicated and expensive than most would want to deal with

And if you went with 24 volts or 48 volts it's more efficient 🤔
I'm sure you'll be fine but fuses are slow to protect unlike trips...
But if you had two more batteries to your pack that would be a different reading completely 🤔
Very nice 👏 👏 👏
Interesting.
5th to view..2nd to like...1st to comment...a dream come true
1st to comment on a comment. I'm really living the life!

Woww
You are so amazing! Intelligent and so beautiful. Love you and your videos! ❤

I think you may have misunderstood. Here is a video I did a while back going over the series arrangement. th-cam.com/video/9VOTLuVy-_M/w-d-xo.html

I think we've got bigger problems if you're seeing volcano ash in the sky.
