You are my hero, it is the first time I see a video of someone doing the unthinkable, only technicians do this stuff. Unbelievable. Good Job.

Thanks for heads up.

There is a difference between 'FATEL FLAW' and ' YOU FUCKED IT UP'

Glad you got your powerwall back up so that you could use them. Next time, I would recommend being prepared by purchasing some jumper wires. You would want 2 male to male jumper wires.

I told my dad to just start reducing usage in the house if it got to 10% vs having to look-up the jump procedure, but thanks for making it a visual process vs reading schematics and line drawings

I have Enphase Micro-Inverters that come alive on their own as soon as they get a taste of the sun. Am hoping that should be enough to to wake a dead PW3. So I need to do some digging to see if the new PW3 behaves similarly and has those JUMPER connections. Thanks for the PSA.

Ty so much for this info. We like many others are completly off grid so if the batteries drain all the way we have the same problem.

I think you can unscrew those 2 screws, and then remove the green plug, so you can take your time to install your wires without shorting, then simply plugging in the green plug

Thanks for the informative video Jeremy

The two screws on the remove the connector, then you can attach the wire to the green connector and plug it in. to solve the other end wrap the wire around a bolt, then the clamp will connect to the then be able to hold the bolts

brother, just a quick question. When you jumped the gateway how did you know it work? Heard something? I truly understand the risk so I only want to know how it worked. BTW, I am a retired NorCal “hombre” living in Costa Rica. Pandemic & death in family had me put away my PW2 away for almost 3 years.

Where online can we find thin info please?

My batteries will flash the green lights and then go to solid green light after the jump start, but then my system doesn't take over to charge my powerwall. Any suggestions?

You already lost grid power so why would it make any difference if you turned off the main breaker? It was essentially off already if the grid was down.

Because what should happen in a grid failure is that the powerwalls take over immediately but they use the main breaker to distribute that power and receive power from the solar panels.

I don’t know if it’s true, but my installer is saying that the current generation use the power reserve within the PowerWall and shouldn’t need a jump start.

Somehow my first part of the comment didint show up. I wanted to explain what causes the situation where you need to jump start the system. The internal computer in the teslka gateway model 1 and 2 is powered either by L1 from the grid or by the battery when the power is out. if you have an extended outage the battery wil lcontinue to discharge beyond the reserve level set all the way to 0% if you let it. This typically only happens if the battery get all the way to 0% the last thing that goes off is the gateway computer. If the power comes back on the computer reboots and all is good. the battery fills with grid power or solar if the sun is out. If you let the battery get to zero and not shut it off the computer goes off and then theres no power to trick the solar systm into turnign on in the morning. its sees no grid and no grid fromt the power wall either. Thats when a Jump will save you as long as thers sun present you can use a simple 12V Gel battery and power the computer. It boots up and hopefully turns on the battery and 240V will go to the solar inverter tricking into thinking the grid is present and it wil turn on and begin charging the battery. ITs importan to turn off all but the battery and solar breakers in the house. You need all the suns energy to get some juice in the battery. Once its up a few percent you can introduce small loads like the fridge or lights. The way to prevent a total failure like this durring along outage if you battery gets to less than10 or even 5% and its getting to be night time or is dark already go and turn off the battery breaker and toggle switch on the battery. that will stop any further discharge and just wait for the sun to come out. Once you got some light then turn on the battery breaker and toggle switch. that will engage the soalr inverter and hopefully if you have light it wil lbegin charging back up. be very fruefgal until that better gets some charge. Remember to prevent it from getting that low during a long outage power off battery breaker and toggle switch to stop discharging. If the grid returns trun that all back on and let the grid fill the battery. If the battery is very cold below 55deg F it wil charge very slowly until it gets warmed up.

Hey, Eric, if you get this, could I possibly pick your brain? I'm having issues with my powerwall and the installer is useless

First of all, last year, our house went for 14 days without power from the grid because of hurricane Fiona (Puerto Rico) and we had continuous power from our 30 solar panels and 2 powerwall batteries. We diligently manage the power used in the house and our batteriew never went below 25% during those 2 weeks. We even used the electric clothe dryer and electric stove (diligently). We also turned the air conditioning on during the sunny days, then turned it off around 5 pm and turned it back on around 9 pm every night (Puerto Rico is very hot in summer). My biggest fear has always been, what happens if the grid goes out and I'm using more Kw than the batteries can handle at that exact moment. Will the batteries just shut off? Then what? My installers explained that if that happened, my emergency 15k back up generator would automatically would turned on (I have an automatic transfer switch) but that situation has not had the chance to happened yet, although the installers did a test and It worked as planned. I forgot to ask, and I've always wondered if I decided to conserve powerwall battery, can I shut down the 2 powerwall breakers, and if that would trigger the transfer switch connected to my backup generator to turn on and provide power to the house. But after watching your video now I'm not so sure. Another worry I have is that I lose grid power at night and don't noticed and the batteries drain before sun up. Would that mean that my batteries would have to be jump started too?

Put it down to a learning curve of life Jeremy, surely though any situation should be in the Tesla handbook, too save you all the stress. I hope your gradually getting back to normal over there!

My system actually shuts itself down once in a while when off grid - every couple months or so, boom. So you need to be able to restart your system off grid even if you don't do anything wrong.

can you make more new videos soon

Further info on why these system can need a jump. This is a continuation message. while the computer is booting up turn off all the house load breakers and only keep on the solar and battery breaker. that way the solar can begin to recharge the battery. once it gets a few percent then you can one by one turn on small loads like the frig and some lights but you want to limit consumption and let the battery charge as much asa it can from the solar. once the soalr is on and making power you can disconnect the battey and the solar wil power the computer thru the L1 connection. I only see this complete system shutdown on extended multi day outages and not enough available sunlight. The way to avoid it from happeing if yoru in that situation is when your battery gets down to 10% or less turn off all unnecessary loads and if you think the batttery wont make it to moring then turn off the battery breaker and battery toggle switch that shuts off the battery and computer. that will stop any further discharge. once the sun returns in the mornign turn the breaker back on and toggle switch on the battery back on. You should have enough power to boot up and startback up the solar and begin recharging. Hopefully the power returns to the grid then your all good again. Hope this was helpfull.

Don’t use braided wire. Save your jetski

Wow guy you saved me!!! Friday night in a holiday weekend and I shut batteries off to add generator ao wife could do laundry😮. Called Tesla ans they said a tech has to do it. It's a 12 volt jump almost any moron could do it if they explained as well as you. Thanka very very much

Wild and crazy, but that’s what happens in disasters

😳

Don't do without knowing stuff. Speak with Tesla support and get advice before touch :)

Heyy

And we just came through a hurricane too

Hi sorry I am sooooooooo late

Only Tesla would overcomplicate an uninterrupted battery backup system enough that it would require a jump start in a range of likely conditions could be met at home.

It's designed that way for safety in the same way the car is. A low voltage system that can turn on and off the high voltage system.

@@abyssunderground it’s called relays, nothing new, safety isn’t why, it’s cuz Tesla likes to pretend they are apple of their industry thus have to reinvent things sometimes amazingly sometimes….this stupid sh*t. Tesla is over complicating it, this could been done even more safely with fewer failure points just using DC-DC conversion from main battery to 12V power to switch some relays when power is lost, it would be even lower maintenance. Could just run 12V all the time hot off of it, probably would add like $1 worth of hardware to the total BOM and last lifetime of the unit, he’ll could make it hot swappable if they wanted to make it a separate module so if that’s a concern then it’s addressable. That’s before consider stuff like contactors and solenoids which could avoid the low power system entirely.
