2000W Mobile Tesla Solar Charger - version 3.0 - more solar, lower mass, battery in frunk!

This video provides an update of my mobile Tesla soalar charging system. See prior videos that cover version 2.0.

Since version 2.0 (version 1.0 with rooftop panels was way too heavy!), I have made the following changes:
1. Replaced 48V EG4 battery with 4 12V battle born batteries
2. Moved the battery mass from the rear to the front to improve weight distribution. Less suspension squat in the rear!
3. Added 4 more frameless 175W solar panels and removed the aluminum frames from 4 of the exisiting panels. Significant mass reduction!
4. Added a Victron battery monitor with Bluetooth capabilities.

Not going to lie I've thought about this but won't ever have money to do it but I'm glad to see someone out there living my dream and making things happen 🎉

You don't know how excited I was to see this video. I just discovered the 2.0 video and then I see that you dropped only the 3.0. I also found it funny how in the 2.0 video you said that the battery was Overkill in the trunk and then now as I'm watching the 3.0 you filled the frunk up with batteries. I really wish you could charge this car DC to DC. It would get rid of so much of the complexity. This is one of those things that everyone thinks of, but you actually did it. I also was watching the video about the haters, I would not take any offense to anything they have to say. However you should be very proud of what you accomplished.

This set up would be great for rv folks. Who go camping and the vehicle sits for days. They can charge up the car then use either the car or the solar panels to run the RV electrical systems. It's a win win set up.

I appreciate your character..
Function over form, just to prove a point..

I am led to believe that 50% output from solar panels labelled output is the norm. Heat, solar intensity and panel orientation are the main things. I love what you are doing with your Tesla, great experimentation.

it might have been said before...
take the LAT you are at and add 15,
that is the angle you need to place your panels to the sun to get full wattage out....
Great job, im inspired!

[t.j.kniveton]

Love this! I've been wanting to figure out a mobile charging solution, and as an EE, was stumped by the mechanical engineering side of deployment. Love your simple and effective solution!!

[stevespawn]

Love it. Cool so when car is topped off the battleborns get topped off. Free gas station -take with you. 1200 watts coming in will add up over 6 hours. Maybe 6-7 kWh-for free if sun is shining. I personally just use the solar on my house grid tied. These mad max approaches are fun fun fun.

güneş enerjisi ile şarj işlemi 🤗
ister evde ister iş yerinde ister piknik alanında her zaman heryerde şarj yapılması harika 😉👍👏

The drag that is caused must be as much that is put in from the solar panels. I thought the solar panels would be stored inside the car when not in use??

[jameskniskern]

Seems like you need a south facing steep slope to set up on... ;) Great idea. Great implementation.

I hope to see you get a cyber truck and fit adjustable frames in the back to properly orient panels while charging. This is awesome!

This is a little simple, but I was thinking; one way you could increase your input would be to first increase the length of the wires connecting each panel to the next. Then, put some "legs" under the top part of each panel, so you could adjust the angle; point each panel more toward the sun. The "legs" could be very simple, maybe just a bent inflexible wire running on the underside at the top, hinged so you could swing it down to hold the top of each panel up. That could go a long way toward aiming your panels more directly toward the sun.

If you also handle the Air drag with a case or something you will have better mileage. Also if you elevate the solar panels from the ground on a sunny day they will have better performance in hot climate cause wind movement around them so faster charging. Or you could face them direct to the sun also. You need somekind of aerodinamik box that can also be a stand to them or something. But other than that cool project.

I see the shadows on the solar panels from the cable aling the line. Even small shadow has a big impact on dropping the performance. Amazing setup tho 👍

In Australia they can use the machine that print labels for canned goods to print photovoltaics. They can run for metres behind the car when parked, like these panels, but simply roll it back up and put it in the car when not in use. Best to use a cylindrical postpak kind of thing to keep the edges in good condition. Cost is around $20 for the roll of paper

[jaysonstebbins]

That's awesome man! Gotta take in consideration your efficiency drop from the inverter. 10-20%? So 1200 watts input on your solar is about 1120 watts then 1120 watts at 85% is about 950 watts. So a total from panel to outlet is about 75-80%. Just thought to keep in mind. 2000 watts if achieved would be about 1600-1700 watts at best to the car? Cool stuff!

I love that this has been done, great job. This might work out better with a ford lightning.

[brianreynolds]

Fantastic idea…well thought out too!…Brian in the UK.

[swss]

I like it how your battery terminals are like an inch away from hitting your frunk cover. Be careful out there…
