The GENIUS of the Tesla Powerwall Explained

special shout out to Tezlab 
for making this video possible   the must-have companion app for any tesla owner   i have been waiting two years 
for my tesla powerball and now   i finally have it installed i've had it 
for about a month i've had a chance to   use it to understand all the 
different settings and the properties   and in this episode i want to talk to you about 
everything you need to know about the powerwall   first and foremost when you buy the powerwall 
and you have it installed i want to walk you   through what you can expect first all of your 
electricity for your house runs from a service   panel in this panel you have electricity 
being provided from your utility company   on the street and in this panel you have different 
circuits or different junctions and the reason is   because there's a limit to how much power you can 
draw from copper wire so to spread that out and   make sure that you're not having a microwave and 
a hair dryer constantly overloading each circuit   you break out your house into different circuits 
why does this matter because when tesla comes with   their power wall they're going to create a new 
sub panel they call it the critical loads panel   the idea here really is to back up everything that 
you can with your powerwall depending on how many   powerwalls you have that will determine how much 
you can back up so for me i have one power wall as   a result my air conditioning my double oven and my 
tesla car charging is not backed up those are over   30 amp loads but everything else in my house is if 
you have two or three maybe you can back up your   air conditioning maybe you can back up your double 
ovens and things like that talk to your reps at   tesla to ask those questions and get clarity on 
that so step one they'll come in and they'll pull   all these circuits out of your main panel so 
my main panel was really busy before now it's   almost entirely empty because all that's left are 
the things that are not backed up from here you   have a gateway that is also installed now this is 
where tesla's incredible eye for detail and their   gorgeous products really shines this typically in 
most companies the gateway is an ugly black box   made of plastic or steel this is white and it is 
glass but in this gateway lives the heart of the   internet connected device which knows what's going 
on as far as how much power your house is using it   makes the judgment of detecting the grid and when 
the grid goes out to switch to the power wall this   happens instantly you'll see the light flicker for 
like a little bit but otherwise computers don't   shut down nothing happens all of our desktops 
carried on nothing crashed or anything else   my powwow is a gorgeous candy apple red and 
other than that aesthetic look it's identical   to every other powerwall the power wall has 13.5 
kilowatt hours of storage capacity now i thought   this was a lot but here in july and august in 
san diego i'm running my air conditioning and   turns out 13.5 isn't as much as i thought because 
it can't power my house through the entire night   but if my air conditioning wasn't running 
that could actually be enough to power me   till the next day when the sun comes back up 
again now that brings up the solar portion and   by the way if you're considering going tesla 
solar or powerwall and you want to save 100   and help support the show consider using our 
link it would help us out and we're hoping to get   future invitations to tesla events so thank you 
so much for your support as always so you have the   option of either going solar and powerwall or just 
powerwall and that will change a couple of things   for one i already had solar so when the powerwall 
came in they took the solar leg coming into my   service panel and they run it into what tesla will 
monitor and record and feed into the power wall   when there's excess energy if you don't have solar 
then you can actually have your power wall charged   from the grid now this might vary from utility 
to utility so talk to your tesla rep they'll   know the rules in your region to help answer 
that question all right next up let's hop   into the mobile application inside of it 
you've probably seen your car in the past   but now if you swipe to the right you'll see your 
power wall so first up we have power flow so power   flow is showing you what is happening right now 
3.2 kilowatts is what my solar is producing and   what it is doing is it's powering the house and 
then whatever's left is charging the power wall   in the performance section it shows you how much 
of your power was from solar or the power wall so   today only about five percent not very good but 
it will get better uh later in the day the backup   history will show you when the power outages have 
occurred and for how long so you can always check   in here and go interesting the power went out 
but i didn't even know because i have a powerball   and finally the most interesting part is under 
customize here you have all your different options   if you want the power wall only to just be fully 
charged in the event of an emergency you'd put   it in backup only but that's not very interesting 
there's better options second is self-powered what   that means is when the sun is shining and you're 
making too much it'll charge the battery and when   you need a little bit more it'll discharge the 
battery simply put it will try its best to never   use the grid next up is advanced and this is 
where you want to be if you have time of use   here in san diego we have different billing based 
on time of day the most expensive is 4 to 9 pm at   50 cents and midnight to 6 a.m for me is 9 cents 
for charging things like my car so if you put it   in balance what it'll do is it'll try to power the 
house and then charge the power wall as best as it   can if you choose cost saving mode then the power 
will charge up as fast as it can and it'll wait   until the time you specify for when the prices 
are really high so here you can edit the prices   and you notice that i've got 4 to 11 30 
as my peak time even though it's 4 to 9 i   have the power wall just go ahead and power 
whatever it can until it runs out of energy   after 4 pm so down below we have storm watch which 
means that the tesla is monitoring if you live in   like florida and you have hurricanes and things 
little monitor for events that could cause power   disruptions and it'll be prepared for that and 
you even have an option to charge your vehicle   even if the power goes out to a certain amount 
so we've spent a lot of time in the tesla   app and as amazing as it is there's one other 
must-have app that i use all the time for my   tesla and that is the teslab app here's why the 
teslab app is so amazing in track you can see   every trip you have taken on your tesla every time 
you start and stop it and it tells you how far you   drove and how efficient you were if you're a 
business professional and you drive for work   this is the killer application feature for me 
with one click you can export bring it into a   spreadsheet and track which was for business 
which was not and have exact mileage figures   it also tells you your battery scores and 
how your battery is performing over time   and how much range you're getting the levels of 
degradation and performance and there's even a   leader board and a community element that really 
gamifies the entire experience as if driving a   tesla wasn't fun enough already so if you want 
to have the must-have tesla app for your car   go to 2-bit signing up is free and 
if you want the longer term data of the pro app   then that cost about as much as a cup of coffee a 
month so that's the application so now let's talk   about what type of mode and what type of a user 
you might be first and foremost if you have solar   you're either a net energy metering customer or 
you're not net energy metering means if i make   one extra kilowatt hour today and i need an extra 
tomorrow they offset and my bill would be zero   if you don't have that you really want to get a 
power wall because when you have excess solar you   charge the battery and when you need that power 
when the sun goes down you have the battery so in   terms of lowering your bills and if you don't have 
net energy metering a power wall is a good idea   second maybe you have net energy metering but it's 
a really crappy deal and what i mean by that is   if electricity costs you 20 cents when you use 
it but when you give it to them they give you   five cents that's not a really good 
deal that means that you would have   to give them four kilowatt hours to offset 
one that you would use later in the night   so if you have no net energy metering or a bad 
energy metering plan a powerwall can help you   offset later energy usage when the sun goes down 
without involving the grid the next question is   if you're a time of use customer here in san diego 
we have time of use 4 to 9 pm is really expensive   so what my powerwall does is allows me to charge 
from solar all day and then come 4 o'clock it   kicks in and tries to cut my usage in that peak 
period completely to zero and what's really cool   is because my solar system is still generating 
a little bit of electricity i'm actually going   to get a negative bill in that period because four 
o'clock usually is around negative two kilo hours   five o'clock is like negative one and then the sun 
goes down and i don't get much after that but the   power wall was powering the entire house in that 
entire period so those are the different kinds of   categorizations that you would have but the bottom 
line is if you want to offset your energy usage   the power wall is an incredibly awesome way to do 
that and if you're trying to make it an economic   choice time of use is really going to be the 
key if you can charge it at earlier time and   discharge during the expensive time the power 
wall will just pay for itself that much sooner   in solar there is a huge important phenomenon 
called the duck curve and what happens is   in places like california where we have 
high electricity prices and tons of solar   there's so much solar during the high noon period 
of time that the state of california is actually   wasting it there's way more solar generation than 
is needed isn't that crazy because we don't really   have much in the way of battery banks and stuff 
pg e is working on a utility sized powerwall   installation which is great but we don't have 
enough in the way of storage so as a result when   the sun is shining we don't need that electricity 
and then at 4 5 6 pm when the sun is setting   we don't have enough and then so the power plant 
operators have a huge challenge trying to figure   out when should we buy power when should we not 
some power plants called base load power plants   are always on nuclear for example others are 
called peaker plants and they can get turned   on and off when the demand is high these are 
the dirtiest types of energy either natural gas   or coal or something like that and they are very 
expensive as well and if we all have power walls   we distribute our energy creation and storage 
we would not need peaker power plants and that   is the environmental benefit of the power 
wall all right now let's talk about the tesla   installation experience first of all they'll send 
you emails ask you to take photos of your electric   panel where you want to install it you have the 
choice of installing in your garage if you live   in a place with really hot or really cold weather 
you might want to do that here in san diego the   weather is pretty nice and i didn't want to lose 
any storage room in my garage so i chose outside   you submit the pictures and stuff they'll schedule 
plans and meetings they'll come out for the first   day they took all of my panels and circuits over 
from my main panel to the new tesla critical loads   panel that pretty much took an entire day so the 
actual tesla power wall hanging and installation   happened on day two so on day two they came out 
had the gateway all plugged up they hung my power   wall and it was fully online and working day three 
which happened about a week or two later is when   the permitting office came down the representative 
from the city and they opened up all the doors   checked everything and i got my permit approved 
then the final thing would be tesla will schedule   a chance for you to come out and if they had to 
cut drywall inside to access your circuits on the   inside of the house or if they had to drill into 
your stucco or your siding on the outside of the   house they'll come out and repair all that stuff 
the only issue that i had was when i first had my   system all installed what i noticed was when the 
air conditioning kicked on the power wall never   even tried to match it what i mean by that is the 
ac is not backed up and i know that if the power   goes out my ac will not work interestingly because 
i have natural gas and the furnace is backed up i   can still get heating which is pretty cool but 
ac will not work and i know that but what i was   thinking was the power wall can output 5 000 watts 
or 5 kilowatts instantaneously and continuously so   at 4 or 5 pm if the ac turned on the power wall 
is actually capable of supporting that much power   and keeping my house running and keeping my bill 
at zero but it wasn't it wasn't even aware of   those loads and so i called tesla and i talked to 
him and they came out turned out they had made a   mistake and they were monitoring my critical loads 
panel not my entire panel right the difference is   the critical loads panel didn't have the double 
oven the air conditioning and the tesla charger   they came out and put cts on the entire panel so 
now the power wall is monitoring my entire house   usage so if i turn on my air conditioning and my 
double oven and my car charging and i'm using 10   000 it can't do all of it but it will eat up five 
thousand and i'll only pay the difference which is   pretty awesome i love my power wall every 
single day i know it's a full charge   and it is using the battery during the really 
expensive periods of time and my bill is even   lower than before the one request i would have 
and this isn't really to tesla would be to allow   the power wall to charge on the grid even if you 
have solar at midnight because at midnight i paid   nine cents so i could charge my entire battery for 
about a dollar 30.

Then instead of having to use   up 13 kilowatts of solar during that period when 
it's 30 cents i could send it back to the grid   and get about three dollars worth of credit and 
then my battery would be fully charged for the   four to nine pm like it does now currently that 
is not supported and it's because of my utility   company they don't want batteries charging on grid 
at earlier times and discharging that might change   because really energy arbitrage is what we really 
need here in san diego and california in general   and around the world storing electricity is the 
goal so i think this will change and when it does   i'm sure tesla will have a software update in the 
future so that is the tesla powerwall one of the   most amazing pieces of tech that i've ever bought 
i know it's just a battery hangs on your wall   but i find it utterly fascinating and if you do 
too and you're interested in going tesla for solar   and batteries we would hugely appreciate it if 
you used our link it helps you out it helps us   out and it gives us more visibility with tesla for 
future events and activities so that pretty much   wraps it up for us hit subscribe like this video
