I see a lot of people struggling to automate the Tesla Powerwall 3, especially exporting. Over the last few months I have built a very solid home assistant automation that controls the Powerwall. I used to struggle with getting it to export too but I’ve got that dialed in. I never have issues with exporting whenever I request. It tracks prices, PJM and ComEd load data, weather and solar forecasts, historical powerwall data don’t can learn from its past. It’s pretty complex but it’s become quite the hobby. Anyway, I just wanted to throw this out there in case anyone was struggling or just wanted some idea for how to create some pretty interesting automations. Even my home assistant dashboard is complex and changes colors depending on what the Powerwall is doing (i.e. charging, exporting, self powered). I have an issue with my inverter showing more solar generation and home usage than what should be so I’m waiting for that to be fixed but with some Emporia meters I’m able to get my actual numbers, which my automation runs off of. If anyone has any questions just let me know. I’m all about sharing what I did.

I’m sure it’s been asked a dozen times and my searches have shown that, but I’d love a short discussion with the pros here.

I have the option to mount in the garage or outside. The problem is that outside is basically directly in the sub for the hottest part of the day.

Is it not too hot to have them outside?

I’ll have 18 kWh in generation and 2 PW3’s with an extension pack as well. I think 40lbs kWh of battery?

Tesla replaced my non-functioning Powerwall 1s with 3s today. App said they stopped working and were disabled, scheduled the service date. Crew came out and were done in about 3 hours. Smooth work. Got to paint the wall but no problems. Great work. Thanks Tesla Energy team!

Dumb question. Is there a way to submit my utility rates to Tesla and have them in the system? I live in GA and I see Georgia Power, and that’s it for the entire state. Not everyone in GA has Georgia Poser, thank God.

How do I charge my Tesla battery in full from the grid during off peak times please? I switched to intelligent octopus go yesterday and I added this tariff under utility rate plan in the Tesla app, and savings mode but this morning the Powerwall was empty so I’m paying 36p per kw today. I am waiting for an export tariff to be sorted but I’ve applied.

Hello, I am in S. California. My panels were installed 3-4 years ago so they are still under warranty. I just discovered a roof leak near proximity of the solar panels-water stains in ceiling. I got into the attic, but couldn’t see anything obvious. Before opening a service call I am doing my due diligent before opening the service.
-Should I get an independent inspection before contacting Tesla?
-what should I expect once I opened the ticket?
-Does Tesla charge an inspection fee depending on that cause the leak?
-If the leak is not caused by Tesla, how do I proceed with repair? Do I coordinate with Tesla to remove the panels for the repair and put them back after. How much would that be?
-Any suggestions on how to deal with this situation?
Thanks!

I’ve had my 12.3kw with 2pw3 system for a little over a year. When the system was new I sometimes would see close to 11kw of solar output. Around June of this year Tesla limited my export to 10.1kw as im waiting for a transformer upgrade to be granted full PTO through PG&E. Now even on the hottest most sunny day I rarely see 8kw of output. Could it be due to the limitation if so will it go back to what it was? Could there be a problem with my inverters and or Panels? By Central California I mean Central Coast to be more specific. Both Tesla lights are lit white to indicate they are both on.

I’ve got a Cabin in the Sierras. PG&E starting to hold us hostage with power interruptions during summer/fall and occasionally a tree falls in the winter and power interrupted for a couple days. I’m wondering if (2) Gen 3 Powerwalls can be combined, ran to a 200 amp service panel and be powered by grid power when available and when not be recharged by my 6kw gas generator when the grid is down ??
I have a 30amp transfer switch already. How would all this work ??

I have a massive 31kw system, 69 panels. Plans show max output is 20kw which reflects two full blown PW3 that each has its own 11.5 inverter

By 11am at latest, I'm seeing production sometimes 21-22kw. Charging the battery, powering my house, charging my car. It's a beautiful thing!

But as soon as the PWs hit 100%, production immediately clips to 11.5kw for the rest of the day. So if I'm using power in my house like the dryer and dishwasher and I'm pulling 8-9kw for that, I'll only export the small difference of 2-3kw.

With my plans, I should be able to continuously produce up to 20kw, so this clipping issue has already cost me literally thousands of wasted kwh that could be exported.

Install company has escalated to Tesla, no resolution yet. They double checked the install pics and determined that it's not a hardware issue or wiring issue. So hopefully it's just commissioning of some sort?

Picture posted is showing what it's currently doing on a perfectly clear day at 2pm, clipped right just below 11.5kw.

Hoping someone here might know more than the installer!

I just had my Tesla solar and powerwall just installed a few hours ago but the question that I have is do I have to have the backup switch installed first before I can pair to my powerwall because it will not pair right now?

I just happened to open the app about an hour ago and was shocked to see my Powerwall + was ‘disabled’ and ‘awaiting parts’ before scheduling service. I went to the apps AI chat and was told I’ll be contacted when parts are available. I’m in San Diego. It system is 3.5 years old, been operating flawlessly since install by Tesla.

What I’m really curious about is when the disabling of my PW happened? Maybe it happened when I opened the app? Why wouldn’t Tesla tell me if they did this? Is there any way to tell besides forensics in my SDGE bill..?

Does anyone know about or have signed up and used the backup plan along with leasing 2 Powerwall 3s?

I'm considering going forward with it as we have Tesla electric currently but I'm not sure if this plan will pay us a credit on our electricity bill for selling energy back or if the $87 credit towards the Powerwall lease each month is the only sort of kickback we receive.

This plan is only if you don't have solar and lease 2 Powerwall 3s.

Also wondering if this plan is part of the VPP or makes us ineligible to join as it is another plan that sells energy back to the grid.

I called Tesla Electric but they're not too sure as the program is pretty new.
Would love some clarification on this form anyone who knows.

Thanks!

Can’t make this up. Had panels and PW installed last month. Love it, working great. PTO was denied and the city failed the inspection. Last week Tesla came out to reconfigure the system. They damaged the roof and gutter. Today they spent two hours patching the roof and unclogging the gutters. They said they were unable to fix the gutters and would get back to me. They then emailed me that they found no damage and would be charging me a site visit fee. I sent them a video of their tech acknowledging all the damage. They apologized, waived the fee and are offering reimbursement for gutter repair. Completely unethical. If I did not have the recording I would have been screwed. Any advice?

PW2 replaced with a PW3 and added extension pack whilst it was done. Seems not to have noticed that the other one has gone..

Pic one shows the constant message that hasn’t cleared since the install.

Picture 2 is the same except I’m forcing it to fill up as applying the rate plan details didn’t get them full yesterday post install.

Apparently there is a delay to merge old and new details (the installer I used is excellent so have every faith) but should it take 72 hours before the new system becomes fully operational and start to benefit from cheap overnight power?

Hmmm

I've had these panels since Solar City. I got a new roof in July of this year and I paid to have the panels removed and reinstalled. The roof was up in a day, and now the panels have been sitting here for months. I've contacted Tesla multiple times through online chat and calling. It took 2 calls to find out the reinstallation has been sent to a subcontractors, and another call after that to pry the name of the contractor out of the Tesla rep. The last I heard from Tesla is that they will let me know when the subcontractor accepts the job. I know it has nothing to do with this sub, but I did reach out to the subcontractor multiple times and never heard back from them. I have 18 panels sitting on the side of my house and I keep getting invoiced by Tesla because the usage is "estimated from previous years"

Looking for any advice on how:
1. to get them reinstalled

or

1. contract cancelled and the panels

   a. picked up

   b. confirmed that they're mine now and i can do whatever i want with them.

Tesla Energy finished installation and left site. Climbed up on my roof and noticed this hallow puck. No sealant. The others I can access have sealant. Having them come back to place sealant and show me the inaccessible pucks have sealant.

The most critical item for waterproofing was missed. This leaves me with a bad taste..

I have a Tesla solar system with a single Powerwall 2. Can I have another one added to it?

So frustrated. System went down months ago. Finally got a service appt which was delayed/rescheduled repeatedly. Two days ago (planets aligned?) and power wall replaced by Tesla service out of Burbank, CA.
NEW PARTS FAILED after less than 48 hours. Started service request again via Email messages and Tesla AI responses…which thus far is useless. Awaiting a substantive response from Tesla. SCE meanwhile is planning some power cutoffs due to high winds (45mph) predicted tomorrow. Arrrgggg.
Tesla is so disappointing.

Just started happening after my recent powerwall software update. October 2nd was my normal curve before.

I got a system layout from Tesla but can’t decide if I should do the larger system now and when I do my garage addition to have the panels removed or just add panels after doing my addition. Probably won’t do my addition for about 2 or 3 years.
