- I finished my RV build in late 2021 and I charged my Tesla from the RV all year during 2022. In this video I go over the charging setup I have in my garage then I go through the results from 2022 showing how many miles were charged to my Tesla through the entire year and other stats.

Since Battle Born (my battery manufacturer) says their batteries can be used with no detrimental effects up to 138 degrees F I decided to not use the mini split to cool the trailer this year (2023) until the batteries get up to 110 degrees F. It is now August 2023 and the battery temperature has never achieved 110 degrees. That means this year I haven't used any energy for cooling the trailer cabin and thus cooled the batteries and all energy has gone into the Tesla. Most of the time the batteries are under 100 degrees and only get over that when they're being heavily charged or discharged.
Your solar panel in the rv roof is the first one i see that makes sense ❤
Cool setup! I love how much thought you’ve put into this. It’s become its own power ecosystem.
Thanks, and I agree. Once I'm able to tow the trailer with an electric vehicle it'll be a fully mobile self sufficient setup. Granted the daily range from solar will only be roughly 4.75 miles per day (1,731 miles per year if the Cybertruck uses 800 Wh/Mi while towing) which isn't a lot, but if we stay camped in the same location for a couple days it's a usable amount of energy and better than slowly losing range out in the boondocks.
A lot of data, and very well presented!
Thanks for the effort to share it.
Thanks!
Lots of data crunched, but it's good to know there is quite alot of energy wasted if not when your camper during its downtime. I'm in a similar situation, except I don't have an electric vehicle at the moment. However, I am on grid-tied solar which give me an idea of converting my current 30 amp RV trailer with 1,200 Wp solar and 15 kWh of LiFePO4 storage to 50 amp 120/240 shore power with some additional hardware. I believe if I add another Victron MultiPlus 2, there is a way to sell the excess solar back to the grid. It might not a whole lot of extra energy, but it's better to put it to good use than to lose it.
Using a mini-split heat pump is definitely a game changer, since I live in a subtropical zone I keep mine in dehumidification mode and it runs fine on its own without shore power. It definitely kept it a toasty 72° F one winter when it was in the upper 30's for a several days when I had a family member staying there while on visit for the holidays. I just plugged it in on shore power to make sure they didn't kill the batteries inadvertently.
Right on, I agree with everything you said. I wish there was a setting where Victron would just keep the batteries at 50% and all solar would go straight into my house which already has grid tied solar on it.
Great video. People who've never driven an electric car and don't understand the economics think solar is impractical. But here you've shown that someone with a daily commute of 20 miles or less could offset 100% of that driving with a very modest solar array. Even if you don't have a camper - this kind of setup, in a relatively small area even ground-mount, could deliver most of your driving for free. For people whose utility company doesn't offer net metering or who don't want the complexity and cost of a full-house install, an approach like this can be completely disconnected from the grid and the car can still use most of the energy produced without waste. I am curious if you've run the economics of your system vs. home electric rates and vs. gasoline for a comparable ICE car?
I've measured amount of energy produced on both my grid-tied house solar panels as well as my RV off-grid array, but estimating the cost per kWh is difficult without knowing how long the system will last. I just broke even with my installation cost of my grid-tied system so now it's completely free energy going forward, but for how long? I anticipate it lasting a total of at least 25 years, but likely a decade or two more than that. I'll likely have to replace the inverter at some point though because that's the part that fails more than the panels themselves. The RV system is also hard to calculate the price per kWh of energy produced for the same reason, and frankly I'm willing to pay more for the RV system because it's useful in such a variety of ways being mobile. Comparing gas car costs to electric is a multi faceted topic as well due to the large variance of gas mileage vs miles per kWh of electric etc...
You can also create a inlet connected to your electric panel, just like people use for backup generator. Then just connect your solar from your RV to that inlet to adding electrical power to your house. My2C 😊
The generator interlock device in the electrical panel mechanically switches off the grid at the same time it switches on the generator inlet circuit. Which means yes I can power my house with the trailer's electrical system (which is what I've successfully done to test the system), but it's not something I'd do on a regular basis because it's a hassle to constantly switch back and forth. It is very easy however to charge the Tesla from the trailer which is what I do. If the power grid goes down though then I most certainly do power my house from the trailer and I limit our power consumption if needed to not exceed what the trailer can output. I'll probably make a video about this someday.
How much was your tesla?
Where is the best place to buy a tesla 2013 to 2016 in UTAH
We paid $39,400 pre taxes and registration in May 2019. I outlined that experience in this video. ua-cam.com/video/j2024Gyca-8/v-deo.html
I purchased our Model S directly from Tesla as a CPO model, but I don't recommend doing that anymore because a few months after our purchase Tesla began to remove free unlimited supercharging from vehicles that they sell. If you buy from a private party you can still have it. The best place to find them in Utah is on KSL classifieds or the Facebook group named Utah Tesla Classifieds.
