You did it, Dan! We love how much you learned about your home from energy insights in your SPAN Home app throughout this experiment, and that your SPAN Panels made it possible to go off-grid for a full 48 hours. Resilience looks good on your Dream Home!
How did this only have 6 likes
👍
SPAN is cool
Too
I really think that power monitoring and smart control from something like a span panel is something every house should have. I was noticing though that for this one, it looks like the system has 2x 200a service connections. Is this true?
That would explain some of the deltas seen between the different apps as all of the meters are revenue grade, and it is unlikely they are wrong. It would be interesting to see an actual wiring diagram of how the house is connected as it seems like the span panels are bypassing some of the measurements the tesla app has access to at 15:50. Notice that the tesla "solar" is the same as the span panel "battery" output. Does that mean something is not installed correctly and that the span panels are taking off the power for the house before the tesla sees it on the solar input?
Dang those drone shots are sweet!
Yeah, almost as good as yours
ok
only you zack would take notice of that lol
Fr! Is that the DJI avata?
@@cohens1861 seems like it!
Watching this from South Africa is funny. We live with 10+ hours a day where we have no power. Switching to solar is a game changer here and almost a requirement to live a normal life.
Ja dis altyd lekker
How many people would u say have solar power in ur area? Is it not that much
@@BayareaXotics in my neighbour it's surprisingly many. The best is seeing the installations show up almost on a daily basis. I think most of the country has realised that it's the only way forward.
Same in Puerto Rico i remember for hurricane Maria we went 8 months without electricity
@@TobiasWeberRSA wow that’s awesome well I hope u are enjoying life out there in South Africa 🇿🇦
Hey Dan, I didn’t read through the comments, so someone else may have said this, but it seems that the Span panel is in charge and not the power wall. This would account for some of the discrepancies that you saw. The power walls are being fed from the Span panel, which is why the span panel was seeing the “whole” picture more clearly than the power wall was seeing. Hope this helps! Thanks for the video! Can’t wait to go solar myself.
Agreed. Powerwall showed no usage to the home because no power was going from the powerwall to the home. And the discrepancy in solar incoming is because powerwall only knows what Span is sending it and the house was pulling some power before going to the powerwall.
This is honestly such a good challenge. You really learn to appreciate having power and become more conscious on how much electricity you use every day. I would love to see you guys try this challenge again in maybe a year and see how you change your home to become more and more efficient.
Right? It's an awesome way to learn how your home uses energy so you can take steps to reduce average consumption.
Would have been a much BETTER challenge if they had cut ALL power off from their home. No solar, no nothing. I feel kinda click-baited.
It’s crazy to see how much your house uses even without AC. Even more extreme with AC. Thats no comparison to european houses
And whats even more crazy is that he said he was using even the heaters during night! So he’s using AC during the day and then all that cool air is being heated up during the night?! What a waste of energy. Plus there’s no need to use AC when it’s 80 degrees outside. Like literally, here in Europe, we weren’t allowed to heat up our homes during (freezing) winter to above 65-70 degrees (19-20C) and yet the dummies in the US are just wasting energy.
Yea, passive cooling/insulation first. If the house is insulated it will actually keep the heat out of the doors are closed. 1-2kW baseload is abominable. Anyone would have been able to do that challenge if they properly prioritised the must haves.
He has span but never shows how much each load is using.
Two Powerwalls should always get you through one single night to day in spring- summer, this is nuts that night-morning used 26kwhs
The span panels system seem wasted on the house as it so inefficient 😢
@@vitkrivan9380 hey hey. Not all people in the us have 1000s to spend on energy. Some of us don’t do this 😢
how many European homes are 9000 sq ft?
I wish the Tela powerwalls and chargers would communicate with the Cars to send power from their battery packs back into the house just to bridge the gap between the power walls running out and the solar kicking in fully. It would also mean that the solar could continue at 100% output after the power walls were full and start charging the batteries in the cars. This is something we know Tesla could make, with the app connectivity they already have it would be easy to make them all communicate.
And when the power walls are full, they could start charging the car instead of shutting down the solar panels.
could cause long-term battery health issues
It wouldn't if it were only for short term, maybe if a house didn't have power walls at all and just needed some quick power for a one hour outage. I think if there was an outage once every few months for a few hours the damage that would cause to the battery would be negligable, especially if you consider that power walls exist and do the job fine.
I love tela
As far as I know Tesla cars don't have the hardware needed for the "vehicle to home" mode, and each charger must have their own inverter to make that energy usable in the house (which makes them way more expensive). Some electric cars have this kind of hardware but it's still uncommon.
whats crazy is that he said he was using even the heaters during night! So he’s using AC during the day and then all that cool air is being heated up during the night?! What a waste of energy. Plus there’s no need to use AC when it’s 80 degrees outside. Like literally, here in Europe, we weren’t allowed to heat up our homes during (freezing) winter to above 65-70 degrees (19-20C) and yet the dummies in the US are just wasting energy.
It's good to have a backup like you have installed even though you have such a good grid energy system! Here in South Africa our grid is unstable, we have rolling blackouts every 4 hours or so, so having some sort of backup is a need unless you like sitting in dark for 4+ hours a day. You should do some more videos on the solar side.
Great video Dan! I love the flexibility of SPAN you showed. Our family has about 12kW of solar and 4 Tesla Powerwalls installed. We ran this type of experiment before and after installing a 5 zone Mitsubishi based heat pump system (for cooling and heating), in both winter and summer. I was able to go reliably off grid in both seasons, in part by moving from HVAC to heat pumps. We live in Los Angeles and our home is significantly smaller - about 2,600 square feet - but it's a testament to how much more efficient heat pumps are over traditional HVAC systems. And with the multi-zone nature of heat pump systems, you can just heat or cool the area of the home where you are.
great video and very interesting. done this myself 4 weeks ago and you really learn a lot about power, usage and your behaviour.
everyone should do this to get the knowledge about there power usage
We lived off grid with our Tesla PowerWalls for 11 days after Hurricane Ida! Our solar panels charged our PowerWalls daily.
Well for these guys that is definetly impossible. Their energy usage is insane. I mean, their solarpanels appear to produce up to 9KW and its still not enough. That should be more than enough to power a house for the day
You need a UPS for your network/computers with a managed shutdown script
I don’t know what this means but it sounds like it is something I need.
@@WHATSINSIDEFAMILY An UPS is like an emergency battery, so if you lose power, it's powering it for a few minutes to safely shut off.
@@WHATSINSIDEFAMILY UPS is a backup power device for servers, NVRs etc. Anything you plug into it. It then plugs into your computers, servers etc. either via network or just via USB and when the UPS battery gets low it will tell all the devices connected to it to shut off safely so it just doesn't cut power and risk losing data.
yes, specially to prevent devices from turning off for a split second when switching from grid to battery
@@WHATSINSIDEFAMILY it's like a power generator for your computers. Stands for uninterruptible power supply. It's common for offices to have this.
It takes a fair amount of practice to figure out what you actually need on or off. Awesome video! South Africa is going through this but not by choice, haha!
Excited to see how this turns out
this was an eye opener on how, when n what to use in power conservation n also on hw to go abt power usage in cases of outage
My wife walked in the room and asked why I listening to Ryan Reynolds and told her I was watching what’s inside family 😂😂 never really knew how similar Dan sounds just like Ryan Reynolds and now I can’t get it out of my head
I'm your wife
I'm Ryan Reynolds 😂
It's a good, Hard way to find out if the solar panels orientation was set up correctly. Thank you for this. Will keep this in mind when I finally put them on my house
Cool challenge. Since there were times in the day where the power banks weren't charging because they were full, couldn't the cars get charged during that time? It would use up some of the stored energy and utilize the available sun. Can't wait to finally see what happens to the statue.
American houses use so much power. I have no idea how do you guys even use this much power, like what in the actual hell are you doing to possibly use this much power ? Most American still use the outdated and dangerous GASSSS for cooking and still use this much power. It just blows my mind.
Two words = Air Conditioning. In the US 90% of the homes have AC. We also have lots of space over here for big houses, bigger the house the more air needs to be treated and more power is required to run the AC.
Also no the vast majority of US homes have electric stoves. I think it is something like 70% of the US is Electric stoves and ovens. Except for California and New York for some reason they like their gas stoves.
This is more entertainment than instruction. Timing is important and insolation is much better this time of year. And you appear to be in the southwest so not much weather. Practically, this CAN be done any time of year if one manages demand. And yes, the solar/powerwall/SPAN combination is powerful.
Dan - Can you please explain how in 2023 with LED bulbs everywhere, you are using 1KW for your lighting (15:34) during the *day* ?????
there is probably more than just lights on, such as fridges/freezers, possibly TV, computer, washing machine
Would have been good to see in the span app what was using power and how much
You did this challenge so well and I loved the drone shots i can’t wait for you to do another challenge like this, maybe 72 Hours. You ae my favorite youtuber!
Could you possibly see about putting a WiFi extender close to your Tesla power wall? Wondering if it just loses communication from the WiFi at certain points? Maybe during peak performance times where a lot of bandwidth is being used? Putting that WiFi extender near the power wall maybe help with that intermittent connectivity.
Would love to go off the grid and seeing this video does make me want to do it more! Very cool and educational
Lift masters garage door openers with a battery backup is a must for all my houses. When we moved to our current home it was one of the first things we had installed
These Garage door operators support Battery Backup. Put the batteries in or if they are in there already, connect the leads. They come with Batteries.
Have you looked at the Tesla solar tiles for the other sections of your roof, as they are far more discreet than the big solar panels?
great video man! very informative!
Get the Liftmaster or other brand garage opener with battery backup which also has wifi and belt drive (very quiet). I was amazed one time when my wife came home when power was out and it just worked. Very nice feature.
Great video,keep them coming
they use more energy in one day than i do for my home in a month
their energy usage is about 10x the global average for a household and 2.5x the US average for a household
@@wcovey25 which is a very big shame! Such a waste of energy
And whats even more crazy is that he said he was using even the heaters during night! So he’s using AC during the day and then all that cool air is being heated up during the night?! What a waste of energy. Plus there’s no need to use AC when it’s 80 degrees outside. Like literally, here in Europe, we weren’t allowed to heat up our homes during (freezing) winter to above 65-70 degrees (19-20C) and yet the dummies in the US are just wasting energy.
@@wcovey25 Wow, this is insane! I guess US average is already quite high compared to EU so beating even that by 2.5x is just so wasteful. I mean, a lot about their house is a big waste. And not being able to sustain yourself with up to 9kw from solar and 2 batteries is insane.
It's because in some places they have "free" energy with hydro and nuclear. which is super cheap relative to for example the netherlands. where power currently costs 40 cents/kwh @@vitkrivan9380
I live in Denmark where aircondition is rarely used or even installed. Like the office building I work in has no air conditioning. We do have 82 here from time to time during the summer, and you don’t need AC for those temperatures. Yes it’s a little bit unpleasant, but you can easily do a couple of days with those temperatures.
Span and the tesla wall are amazing. It's so cool how your power goes down, but you still have power!
Also, late happy birthday to Claire 👍
It's definitely a cool experience! Especially being able to see exactly where your stored energy is flowing in real-time in the SPAN Home app. ⚡
@@span_io it's amazing
I live in rural Pakistan and the grid turns off many times a day (load shedding) and we have a ups but it’s not always enough especially in the hot summers when we want to run the ceiling fans.
I have AC but the grid turns off more often in the heat so I’m not able to properly use it.
I have been looking into solar to power my whole house ,but It’s expensive and the lithium battery’s are even more expensive. 😅
Basically the experiment you did is just like what happens here when the grid goes off for hours at a time.
Happy Battery Birthday Claire! (Great video btw!)
our electric went out for 2 weeks and we handled it very well. Kept the shades closed, doors, ,etcc.
Especially if the entire Grid goes out through the Country.
what else is best for people to have security cameras!!!
We visit your city a month ago, it's so beautiful there and the citizens are so nice. Throughout Utah it's pretty.
Good Stuff Dan Powerwalls & Span panels are a great combo.
We couldn't agree more! SPAN Panel paired with Tesla Powerwall provides the ultimate home backup.
Back in February 2021 there was a severe ice storm where I live and it’s very unusual to get weather like that, but from it we lost power for 5 days and it took out nearby cell towers so we had no wifi, cell service, and heat
Edit: we had to then opt for a generator afterwards instead of solar as from late October to early mid April we don’t get much sun
I work for an electrical utility. I need some of our customers with solar to watch this video to show that even with a lot of solar and batteries you would still need some help from the utility at times to keep the power going and what it would look like if you were actually off grid
Dan what you just explained about why the power pack only charges up to 97% is what is called controls engineering or having feedback loops that can change in real time.......I would know since I just graduated with a B.S. in Robotics Engineering
This is what it feels like in South Africa everyday with constant power outages. Such an amazing video love the content!!
True! even if you do have solar panels you get battery anxiety during the night because there isn't any sun to charge the backup battery.
Your frustration between the mismatch of generation and storage is a perfect microcosm of the issues faced by the grid!
and why we need a constant and reliable power source like nuclear along with sun and wind.
I really enjoy your videos Dan, mainly techy but dynamic, like all on this family channel. It would be awesome if you could make a detailed smart home over few parts or security focused video next, (like a demo how it is set up) i wached your last smart home video, you said it can diferentiate yours from strangers it sounds like AI magic. What cameras or recorders can do that else than Luma, i cant get hold of them in Europe. Have a nice day, Matej😊
LOVE these house updates.....i want you to move for more house videos lol
i helped my neighbor go off grid, 7.5 kw of solar and 20kw of batteries, occasionally he needs to use the generator, but it is winter in south east Australia and solar is lousy her over winter because of how south we are. we split his panels 50/50 east and west so he makes power all through daylight hours and only when its severally overcast he will generate little power.
His batteries her set up for cycle life so they are only used from 30% charge to 85% so in essence he is only using about 10kw of his batteries.
I LOVE these house updates. Please keep this content up!
I think I what what channel you watch
@Rangers2k20 Lol
hello fellow jacksucksatlife viewer
@@coolzxr Hello
@@coolzxr hello!
I live in Hermiston Oregon and we have 22 325 watt panels and 10 365 watt panels that all face the south and right now on the average they generate 63 to 65 kw a day. The only thing is we don't have Tesla Powerwalls yet!
This is a very interesting video I really life the span breaker system
17:09 I believe the reason it does this is because the grid is disconnected and the power can’t be sent to the power company. I do think that it is odd that it doesn’t use the solar for the house but it may be for the same reason. And good job managing everything and keeping energy for your house most of the video!
Havent watched yall since the og days before this channel, glad i still get the same vibes now
Here in uk I have the ability to back feed from my electric car into my house if needed my inverter allows this I rarely use the grid.
I use a solar controller through my pcb which incorporates a timer turns off when you know your not producing high power. if circuits power isn’t being produced to supply high power ie water heater it doesn’t turn those on.
Ask your solar installer to check the CPs installed in main service panel. If it’s not picking up all the loads that might be causing the inconsistent readings on the Tesla app
I can give some advice. You can set up the lights so you use less of them for example each of my fixtures have 2 bulbs and when I'm that night time power save mode I use only one and when I'm being really frugal I was set the lights to a color which uses 3 watts or less per bulb
Dan you should definitely try this out in Az during the summer time to be more specific where at in Yuma it’s hotter in Yuma than in PHX
Car coming out is so nice❤❤❤ 12:33 +Tesla sounds
cool house you have. when I was a kid our power got shut off all the time in the summer because my parents didnt have the money for the bill. 90+ degree days with no fans - no fridge. we had coolers. >>>> memories .
Seems like you need to complete the solar roof. All that wasted space that can be used for solar. That house should be able to run off the grid without cutting down energy usage.
So my question is, would it be better to do the solar roof tiles and maybe another battery because then maybe you would be able to sustain being completely off grid? An you would also beable to get more solar energy from start to end off day?
I’m ou should have put a emergency battery under your desk for your computer, it would of made thjngs so much easier😊
Excellent video there are a lot of things you could do to be better prepared. I am in 🇵🇷 Puerto Rico have the same system We have also battery backups (ups) in the Internet and other stuff. We go off grid every week because the grid is really bad. SPAN did not want to install in my house neither sell the system to me 😢. I am relying on other equipment to do something similar. But awesome video.
I believe if the home was also smart, you could pretty much configure so that when the battery is full, you can run the A/Cs on "max" so you can also create a thermal battery in the house. This way you can use way less power overall since you have the overflow during the "A/C time" and allow you to run more devices @ night. This is something TechnologyConnections mentioned about off-peak grid use, so I think it would also perfectly apply in the opposite case here of on-peak sun hours ☀☀
connecting to and disconnecting from the grid: minimize your usage to minimize the arking and the current surge. A current surge can burn out equipment and devices. Example : the power company forgot to notify our processing plant before restoring the power. The power company had to replace 3 35 horsepower 3 phase m
Awesome video. Thank you
I love you videos so you that teals powerwall 2 with the larger compasity help you house completely off grid?
Always happy to see that Zack's statue is still there.
If the house is connected to the grid, will the power-management system still exclusively use the Powerwall if it's charged enough, energy demand is low enough, and there's no solar input power?
This would be dependent on the home battery system's ability to manage the grid connection. SPAN Panel monitors grid activity and offers load shedding when an outage is reported, but it doesn’t manage disconnecting from the grid on its own.
For the weirdness of the applications. Maybe, the tesla doesn't know that power is use in the house because it's from the solar panel only.
Instead, the SPAN app know because all the power from the solar go thought the SPAN system and so, the app know the power consumption of the house and stored energy of the tesla wall
This was a great test, I imagine your solar/usage can be scaled up and down dependent on size of property and appliances. You can switch off fridges for a few hours as long as you don’t open them, in a pinch you could have not used air con etc… during an actual outage, this could be life saving.
Instead of using the Tesla power wall there are modular systems that allow for more granular upgrades.
Teslas a nice package though.
Nice real world, human test.
Also, well to wheel, EVs still contribute less CO2 than ICE vehicles.
Span needs to go international, absolutely cracking idea.
Thanks for your support, Jonathon! Keep an eye on us as we continue to grow. 😉
Happy birthday Claire
I wish SPAN was available in Australia. I'm building a house and going full electric. Planning on getting 13kW solar and one Powerwall 2 (thinking of getting a second maybe). SPAN would be nice to have so I could have more control over the house.
Yeah me too, span needs to start selling in australia
Thanks for your support! While SPAN Panel isn't currently authorized or listed for installation in Australia, our products may someday be available in your area. Be sure to keep an eye on our growth!
@@span_io will do!
This video should be titled "Utah Family Plays Vermont Simulator for 2 Days"
Could the CT's for the TESLA power walls be located incorrectly or do the need to be calibrated. The Tesla system is also protecting itself that is factored in.
It is eye opening and the data from the SPAN panel can be used to fine tune the loads and spot efficiency problems. A UPS system would be a good idea to take care of your computers independently.
Cooll idea Dan. Very interesting.
Have you considered an EV with bi directional charging? ...this could be a good solution to your additional power needs. Nissan Lead and Ford Lightening I believe have these features.
I am curious if power packs are available for individual residential properties.
Or maybe a battery solution with old EV batteries that don't have the capacity that's ideal to drag around in cars.
Happy Birthday Claire.🎉 🎂 🥳 wishing you get your wish.. 🕺 ❤😇
I think you have an issue, the span panels create an internal lan between the span panel and the tesla gateway (wired together via ethernet) so you shouldn't have issues with internet connectivity. The blackouts on the tesla app (missing data) could be an issue with the gateway itself, check to see if all the powerwalls are flashing rapidly, this would indicate an issue with the gateway.
Happy birthday clare🎉
Thats a very nice house love this channel keep up the good content
Did you stop uploading on the main channel??
Does your power go into the span first before it goes to the Powerwall, or is the solar wired directly into the power wall?
On the powerwall, do you have a MESH internet for WIFI? It might help the Powerwall is on WIFI fulltime.
Hey Dan, will you tell Claire, happy birthday and, I hope the stars will guide her!
For the power wall, I seriously think the Tesla app isn't doing all that it could do. Haven't used it myself personally but I have Enphase so far I haven't had too many issues. Do love the way that it shows what it's doing. Live and how your showed up was very different from the way that Enphase app is. Personally, since you showed off the spam system, hopefully I said that correctly. It would be quite nice to have that installed here in the house because it would put us to a full house backup system instead of partial backup. With only one battery, I think we could manage the output of it, especially during the summer months where we have sun higher in the sky here in NC. My recommendation is to purchase a few cheap solar LED lights for outside and inside that does not have to be connected to any type of power. And personally, that was a great idea by the girls to charge up some of the battery backups and cell phones and flashlights!😂😂😂😂🎉 Great day to choose her birthday to torture her with one of your experiments as well!
From my understanding, you could possibly get away with installing one more backup battery and possibly get away with having the home stay almost completely active. But yes, if you went with an extra two or three you would most likely have power for days! Or at least enough for a bad winter night!
And thanks for all you do. Keep up the great content boss!
I think that your house is wired up weirdly, as I have found the tesla app is actually very accurate even when the power is out. It also works completely independently of the internet too (and allows for hardwired ethernet if you want). I have a second power meter, and I measure both at 1hz with some home automation and they match to about 0.1% error. I think this is an app explanation issue. It looks like your house has 2x 200a panels, and the powerwalls do not actually connect between separate the two service connections. This means when it is disconnected, there are many ways that the tesla app could measure differently than span depending on how the house is wired and they truly are measuring the correct power through a wire, but just because of the way they are wired, they represent different things.
Do you have a powerr generator, like a gas generator to see how much the difference would be? You have a gas stove so It would be interetsing to see what the power usage with a gas generator would be vs grid
Pretty sure your home isn't 100% running through the powerwalls, do you have two breaker panels? That may be why the Tesla app isn't showing your full home usage? My home is 100% going through the backed up panel so it shows every watt we use.
i think the reason your tesla power wall wasn't working after grid was on because you changed your Powerwall setting to off grid mode. i might be wrong but that's what came in to my mind.
Excellent video!! What is the capacity of your power walls in total?
Hey Dan, I was wondering why don't you put more solar panels on the other side of your golf simulation area? That way you can grab more energy
That house wasn't designed to maximize solar production... most of the roof ridges run north-south, so most of the roof faces have eastern or western and only gets sun for half the day. There is only a small amount of southern exposure, and it's right in front, facing the street (which people try and avoid putting panels on for aesthetic reasons.
so what I've gathered is you need 1 more powerwall, maybe v3 11.5kwh rumored ones, and you could do this flawlessly.
or charge a car when powerwall is full
I think 2 more would be perfect. You could definitely go 24 hours with no grid power then for that size house
I doubt I will get a response but worth a try. ( A ) what if you had a cheap Walmart or Amazon like door mirror and aimed it towards your panel's for a little early morning sun ?
Lastly what about the kids having their own portable backup battery packs in their rooms that they manage?
Then try this again...
Ideally the mirror unless you had some computer controlled ones to move them and always keep them pointed correctly it's kind of a dumb idea but just for the fact of keeping minimum power would it be enough?
Love ur videos 🎉 thanks for the vids
The 0% solar with 95% powerwall charge reading was correct. When off grid, the powerwalls will shut down the solar inverters before they reach 100% charge as a safety measure when your power use is relatively low. The powerwalls can control the solar production by shifting the frequency of the house power slightly. If you were to start using a lot of power suddenly (like plugging in the car) then the powerwalls would switch on the solar again. The trick is you would need to remember to turn off the circuit to the car as the sun goes down to avoid having it draining the house battery storage too soon.
Congrats! Are you going to be adding another powerwall to your system?
Living in the Caribbean we do these test all the time glad I have 🪟 so a/c isn’t turned on in the day. Plus when the grid is out you won’t make it to a 100% in the Tesla app stays at 98%. You just have to reduce consumption mainly a/c, a/c makes people soft like you’re dying without a/c.
happy birthday Claire
Hi, in South Africa having no electricity is our daily lives with the loadshedding we get on a daily basis, we get up to 12h30m daily loadshedding
Feel like that garage needs like...2-3 panels on the east side to get some morning juice inflowing before you get the big dose of sunshine. Have you considered sun tracking systems for solar panels? There are a few cool setups out there.
not sure why he doesn't have some Tesla solar roof tiles installed on that east side that you mention, they don't even look like solar panels
@@coreysuffield I think he covered that, price for Tesla solar roof is crazy high. I had my roof quoted and it was like 100k for a normal suburban roof.
Sounds like Dan's going to grab one or two more powerwalls or a few more easterly facing panels...
Your tesla powerwall maynot be giving out charge to your home whereas SPAN is the one giving power OR unless your solarpanels are directly connected to the Tesla Powerwall. Just a thought :)
having the opportunity to have this kind of hybrid system ({solar + grid} + battery) is lovely and something i would love to have for todays necessities like light at night, a few fans/ACs and internet. i wish where i live we could have this...
i had a part time job in a solar company and every now and then a few clients asked if they could have batteries along side the solar + grid, but in the big city having this is illegal according to the grid company... so we can only have the on-grid kind of system with no batteries
as its also censored illegal to have a full off-grid system.
You should look into Bluettie battery backup home system they have 3 batteries and 1 home ac inverter with wireless connection for app control
