I have a solar and battery backup system. The method I use is in the morning I let my battery charge up while the solar production is climbing because the batteries have been running my house all night. Then I set my car charger to match the solar output with clouds because the battery will compensate for the variation in production. Towards the end of the day I stop charging and allow my batteries to charge completely again to run my house all night. Of course there is a learning curve but is not difficult. This is how the electric company runs the grid basically. They have to monitor and adjust and start up another plant.It's actually fun to me. Also my car charger can be controlled through an app so I don't have to even be home.
Thanks for watching and sharing!
Zappi charger can do all these twicks press of a button on Eco plus.
Thanks for watching and sharing!
I charge my Tesla Model 3 Long range by Solar most of the time.. I use Zappi Solar Aware smart charger which can charge exclusively by Solar. If cloud comes and solar production reduces, it automatically stops charging and when cloud goes away and solar production increases, it starts charging again.. I don't have to touch or change any settings.. It's essentially set and forget.. You should check out the Zappi charger..
Thanks for watching and sharing! Very cool!
This is great, much love from S. Africa🇿🇦… cool experiment 🧪, it would be nice to also see the experiment when there are no clouds but it’s fully sunny ☀️ in summer. It would be nice to see that too. Im planning to get a 16kW system with maybe 30-40kWh battery. I love watching such videos, I learn a lot. Do a summer time no clouds video.🙌🏿
Thanks for watching! I'll get that video request added to my list. Cheers!
@@TeslaFamilyChannel awesomeness.🙌🏿
So nice to just put the energy of the sun directly into your car, something which is able to do hundreds of kms and can be very fast
Thanks for watching!
It would be cool to have program that could do this automatically.
Thanks for watching! I thought I heard this feature is coming in a future update but unsure if a Tesla inverter or Gen3 wall connector is needed.
You can with a span panel
This can now be done automatically with the Charge On Excess Solar feature from Tesla
There are a lot of losses converting from Solar DC to AC, then AC/DC mode charge to the Tesla. We need DC-DC EV chargers we can hook up directly to the Solar MPPT charge Controllers to charge the EVs.
Thanks for watching! Agree!
Solid video. Love more solar videos! From sunny Australia
Thanks for watching! Cool to have a fan from the southern hemisphere!
My Indian engineer friend sold his House and he took off solar panels..and I purchased all.. he helped me install in my garage roof with 2 huge caterpillar batteries installed...works great in my 2 tesla😁
🕺
Thanks for watching and for sharing your solar system!
Curious why he took off the solar
@@Prince-fr2lr he paid cash for the panels
Cool experiment.
Thanks for watching!
Wall connector needs a solar panel mode for automated surplus energy used for charging. At least a dumb estimated charging program.
Thanks for watching, I agree!
We need giant balloons cabled to the ground floating over the average cloud line, covered in panels. As the sun moves across the sky the collected energy will remain the same, regardless of time of year, or latitude. It will be higher because the collection will be way above the horizon at ground level. This totally doable with current tech, even enough so to make it stormproof. I think I need a large grant to make this happen at an experimental level.
Thanks for watching! Some clouds are nearly 10 miles high. Gonna take a lot of cable!
@@TeslaFamilyChannel Just use Nikola Tesla technology to beam it back down to the house!
Do you have the pest abatement installed? Noticed some systems don't have the skirts on the side but I'm not sure if that's just how tesla does it now, I saw some pictures and it seems like it was a fence
I do not have pest abatement or fencing. I have skirting on front and sides but not top. The skirting leaves less than a two inch gap between the skirt and roof. I have also removed or trimmed back all trees around my home to keep squirrels etc from reaching the roof. So far no issues with birds.
What panels and how many of them are you using? I'm planning to diy a solar charging station with 10-14 kwh for charging ev solely.
Thanks for watching! I have 24 Hanwha Q cells panels from Tesla. Check out my Tesla Solar and Powerwall playlist for more info on my setup. Also working on a new video with a cool new feature from Tesla called Charge on Solar.
It is a good demonstration. What month of the year? You were starting at 21% and had 24 solar panels with 7.5 kWh capacity. That is 60% in a shade over 9 hours, If you had half as many solar panels; it would be 9 hours to get 30% if you had a slightly longer day. Did you have any powerwalls in this situation? Tesla is known to slow significantly at the higher percentages of charge - would this be true at the 20 amp rate or could you go higher at the same charge rate without slowing down? Was this 100% of the panel's output - ie. your house if dependent on solar would not be getting any power?
Thanks for watching! This experiment was conducted in May 2021. I did not have Powerwall at that time but do now. I don't think the slower charge rate applies to charging with a level 2 wall connector charger, only with Supercharging which can charge more than 20x faster than a home charger. The wall connector can charge up to 11/12 kW. I was only limiting it in this video to keep from drawing much charge from the grid. There was a time in the video where I showed that I was pushing about 91% (500w/5800w) in the video at about the 4:00 mark. I am going to be completing an updated experiment soon and will post the results using Tesla's new "Charge On Solar" feature.
1)Which inverter you use?
2) Your system is on grid. Can you charge your EV off grid, directly from panels and an inverter?
Thanks for watching! SolarEdge Inverter. I can switch my system to off grid via the Tesla app and charge from Powerwall and solar only. My 11kW charger would have to be charging at a much lower level though.
Which is exactly the model of solaerdge?
What I wonder about is what would happen if you had an off-grid system and your production dropped below the settings off the "charge current". Would it simply stop charging completely?
Thanks for watching! It would continue to charge but at the reduced available current. You can set for example 12A but if there is only 9A then it just pulls that.
Just curious. Would it be ideal to charge your car in months when you need little ac or heat? Like could you use most of the power to charge your car completely in months you dont need much ac or heat?
Thanks for watching! Tesla has a new update that will allow a Tesla Solar and Powerwall owner to charge their Tesla with the excess solar. So you can charge your car completely on solar!
That would be great if you didn't go anywhere during the day but it's highly impractical. I don't see a real world use for doing this since you have to be on top of it all day long. But cool experiment.
Thanks for watching! Yeah, was just a fun experiment.
Maybe on the weekends on a day where no one is going anywhere would be good for a full go
Net metering solves that problem. You send the power to the grid during the day, and you pull from the grid at night to charge.
If you didn’t have Grid Power, could you just leave the Tesla plugged in and it would adjust itself to fully charge?
Thanks for watching! When the grid is out the system also powers off my panels for safety of utility workers which may be working nearby. I don't have Powerwall yet but if I did then the system could charge Powerwall during an outage and that power could then be used to charge the Model 3.
Yes. If the solar panels are off-grid, then whaever power comes out of the panels will go to your car. You don't have to adjust anything.
Does the Tesla charging device draw DC or AC from your solar power grid?
Thanks for watching! The Tesla Wall Connector charger draws up to 48 Amps/ 12 kW A/C so at full draw I need grid credits in addition to my solar to charge.
But given the OUTPUT of your PV array YES you can charge a Tesla from the SUN which is why we OVERSIZED our PV system from a recommended 10.3 kWh to 13.1 kWh PV system. And given the average American drives about 40 miles per day you can see how fast you could add 40 to 50 miles to your Tesla. So start the test at 90% drive 40 to 50 miles and then see how long it would take to replenish the SOC back to 90%.
Thanks for watching! Excited for the next software update to allow charging on excess solar!
u need a 16k- 30k system to charge your care to full in a few hours and power your whole home and charge your tesla battery wall stuff
Thanks for watching. If not charging my car, my Powerwall is charged in only 2 hours. I charge the car normally at 11.5kW which can fill it up in just a few hours.
with a 6k setup youll take 3 days to charge the car.. not counting the house what it takes youd have to not use anything in the house.. so you need 12k 16 k ideal and 30k would be top dog
Thanks for watching! The more panels the better!
I have a solar system that is a 4.6 kw system. I recently wanted to upgrade due to wanting a Tesla. I have a large commute, to get to work I travel 80 miles, so 160 miles a day. The guy wanted to add 16 more panels and two batteries to my system 🤣. Overall he said 60,000 worth of solar, and the car would be around the same price, so 120,000.
Do I even need the extra solar power?
Thanks for watching! What is your current offset based on your current usage without the Tesla? Did you get that quote from Tesla Solar? I've found Tesla to have the best pricing. Do you have net metering with your utility? If so you likely do not need the home batteries unless your area gets a lot of power outages. The extra panels only make sense if you want to ensure your Tesla is largely charged by solar, which would be ideal, or if your current system is undersized, or if your grid prices are very high. Otherwise, when driving your Tesla you do have the excellent Supercharging network to use in a pinch but I would recommend home charging or work charging if you can. If you haven't already get a solar quote from Tesla.

@@TeslaFamilyChannel unfortunately I live in California and it does cost a pretty penny for energy. I’m not a spec guy, and am trying to learn about this through the internet and various videos. That’s said, it is just me and my wife in a four bed, three bathroom home, we have a 4.6kw system purchased through sunrun. This is our first year in a brand new built home, that has smart home capabilities, and is supposed to be energy efficient. We are set to get a true up bill soon of at least 250. Not sure if you’re aware of that, but in California if you don’t produce enough energy and end up using the grid energy they charge you at the end of the year. So I didn’t produce enough solar power this year, and will have to pay out.
I was looking into other companies but the last one I spoke with said they will only install their system and would take my existing panels off, which doesn’t make sense to me.
I’ll look into Tesla panels and maybe even use the link if I don’t hit a wall with them. Thanks for the reply
Thats weird that the other company told you that you have to take the other panels off. Pretty sure Tesla will just add a new (second) system to your home. Here in MD we don't have annual true up but pay back monthly for any grid draw that exceeds what we pushed in. Good luck!
This is stupid checking your phone app every hour. Certain EVSE’s can do this automatically.
Thanks for watching! Please share.
