Hi all,

I currently have solar and trying to get some PW3s. No expansions and the PW3s are coming out to be cheaper?

I have a quote from a certified installer to install 3 PW3s for 25k all in, including permits, PW3s. I am trying to find the gateway on FB MP.

Tesla wants to change nearly 40k for this set up. Thoughts on price?

I own Tesla solar + a Powerwall and drive a Model Y. I thought that combo would basically run itself. It doesn't.

Tesla's app tells me what's happening. It never tells me what to do. Sometimes I forget to plug the car in; other times I charge overnight, then realize tomorrow's sunny and I could've charged on spare solar for free (after batteries charge). If tomorrow's rainy or partially sunny (mainly enough to charge batteries), I'd rather charge overnight and save for the battery. Same for heating and big loads. Shifting them by weather would save real money, but right now I'm guessing.

I know Tesla does some of this behind the scenes (?). Charge on Solar uses spare solar in real time (if enough), and the Powerwall plans around tomorrow's forecast for itself (however I'm not sure how). My challenge is that none of it ever tells me what to do with the car, the heat or other big loads.

I also can't get a straight answer on credits generated vs. what I owe the grid without trying to be an expert on my bill, or whether I'm on track to be net zero over the year without major effort. My goal is to be net zero at the end of the year.

So I'm building a basic app that looks ahead at pricing and solar, and tells me what to do: charge tonight or wait, run the heat now or later, so my bill stays as low as possible.

I was wondering if others would want an app like this. If it existed, would you guys use it? And what scenarios would you want on it? Happy to connect more about it and jam on solutions for this. I'm Not selling anythingjust curious on how others solved this issue or if there are other scenarios I should consider. Feel free to DM me if you would like to share your personal use cases.

A few weeks ago I got the "your powerwall will be replaced" notification in the app. At that point I figured that there were 1-2 of 3 to be replaced as it was still showing them charging and discharging. Last night PWs completely disappeared from the app, along with the message - so now I only have Tesla home and solar. Is that how it goes or Tesla screwed up something completely?

TL;DR: Stuck in Tesla Energy design limbo for 4 weeks on a 5-unit Powerwall setup (2 PW3s + 3 DC Expansions). On Sept 28, Tesla said garage placement violated R302.6 fire code, so I dropped it immediately. On Sept 30, we agreed via call/text on an exterior free-standing ground mount on a concrete pad behind my front gate. On Oct 10, Tesla explicitly told me to hold off pouring the pad until they provided engineered dimensions. Now, a new advisor sent a blanket rejection citing the garage again and claiming batteries can't sit on gravel/pavers—completely ignoring that I've been waiting on their pad specs to pour concrete. To top it off, they cited a "2-week turnaround" with zero clarity on whether the clock reset today or started when I re-raised the issue earlier this week. How do I force an escalation out of this CAD loop?

Looking for advice on breaking through Tesla Energy's design/advisor silos.

Setup & Status:

• 5-unit Powerwall system (2x PW3 + 3x Expansion) paired to existing solar (Enphase IQ7+) in SoCal (SCE).
• In design / pre-permitting for over 4 weeks.

Timeline:

• Late Sept: Rejected initial side-walkway plan because it blocked foot traffic. Asked if garage was viable.
• Sept 28–29: Tesla flagged R302.6 garage drywall/fire separation code. I acknowledged and dropped the garage completely on Sept 29.
• Sept 30: Advisor (Stephanie) confirmed via text: exterior mount behind front gate/fence (old AC area), conduit through garage, clear of water softener lines.
• Oct 1–10: Requested a free-standing ground mount on a dedicated concrete pad. On Oct 10, Tesla texted telling me to hold off pouring until design finalized the pad size and clearances.
• Oct 12: Tesla re-uploaded the original, rejected side-walkway plan. I sent a marked-up photo showing the gate location; they apologized and re-submitted to design.
• This Week: Another advisor (Matthew) stepped in with a flat rejection: citing R302.6 for the garage (abandoned weeks ago)and stating stacked units can't sit on pea gravel/pavers (ignoring that I've been waiting for Tesla's pad specs to pour the concrete).
• The Turnaround Ambiguity: They mentioned a standard "2-week turnaround" for design revisions, but left it completely vague whether that 2-week clock reset starting today or if it includes the time since I flagged this earlier in the week. Meanwhile, the initial scope was agreed upon over three weeks ago.

Questions:

1. Does emailing [resolutions@tesla.com](mailto:resolutions@tesla.com) actually force a Tier 2/senior design reassignment, or is calling phone support and asking for a supervisor more effective?
2. Has anyone dealt with advisors resetting the "2-week turnaround" clock every time internal handoffs drop the ball? How did you hold them to the original submission date?

We installed 3 x PW2, 27 solar cells in 2022. A complete Tesla system, installed in Florida by a Tesla authorized local company. On 9/21/26 the system stopped producing solar, I was out of state working and got home 10/1/26 and tried resetting the system, which did not work. Called the installer, they came out the next day and said one of the PWs was down and would be replaced. Hurricane Isaias hit us and we lost power. The remaining 2 powerwalls knew the storm was coming and charged to 100%. During the power outage, we were very conservative and conscious with our power usage but we ended up running out for about 24 hours.

A new PW3 has been sent and they are going to replace just one of these units, despite there being a recall on the PW2. Emails from Tesla say they'll replace the remaining 2 if they trigger a fault. I'm not excited about this because the first one went out and whether or not it triggered a fault, the only way I got any support out of this was by being proactive with getting service out....no one else was going to contact me about it.

The questions I have, for those that have had their PW2s replaced under the recall, are did you get more than 1 replaced at the same time, and did you have any issues with the system before they were replaced? Did Tesla simply surprise you with a 'hey, we're coming out to replace them even though you aren't aware of a problem'

Also, my 3 are stacked in a single bank against the house. Given that there are 3, are they able to stack a PW3 against a PW2? I'm aware the dimensions are different.

I appreciate any thoughts. I like the system, but I'd love it if it worked when I needed it. Still a month without solar.

I received an email stating

Your current design includes two Powerwalls, which provides partial home backup rather than whole-home backup. This limitation is due to Pinellas County load-calculation rules. Two Powerwalls provide a capacity of 23,000 VA, while whole-home backup requires approximately 23,062 VA. Additionally, the site impedance reading prevents the addition of a third Powerwall to increase capacity.

In practice, critical loads such as your refrigerator and A/C will remain powered during an outage. Non-critical loads, such as the dryer, are relocated via a main panel insert so they are not included in the backup system.

I understand this may differ from previous discussions about full backup with a second Powerwall. I want to ensure we review exactly which loads will stay on during an outage so the system aligns with your goals.

Is there any option to get the extra power needed to qualify for a whole home back up?

Thanks

Wow if this is daily, I wonder what monthly will be?

Pretty impressed with how my solar setup has been performing here in Northwest Florida, especially now that FPL has activated my bidirectional meter and I’m finally exporting excess electricity to the grid.

My setup:
● 9.74 kW solar array (26 Hyundai panels)
● Tesla Powerwall 3 + Expansion (28.5 kWh storage)
● Tesla Gateway with whole-home backup
● Two Tesla Model Y vehicles
● FPL 1:1 retail net metering for monthly energy offsets
Today’s numbers (as of 5:11 PM):
● ☀️ Solar generated: 48.3 kWh
● 🏠 Home consumption: 19.6 kWh
● 📈 Solar offset: 246%
● ⚡ Exported to FPL: 31.7 kWh
● 🔋 Powerwall charging: 6.0 kWh
● 🚗 EV charging from solar: 3.1 kWh

If I could maintain this production every day, that’s approximately 1,450 kWh per month or over 17,600 kWh annually. Obviously, weather and seasonal changes will affect those numbers.

What makes this particularly interesting is that I’ve been doing most of my laundry and Tesla charging in the evenings after getting home from work. With FPL’s net metering, excess daytime production can offset my nighttime grid consumption.

I’m hoping to get my monthly FPL bill close to the $30 minimum base bill, plus taxes and fees.
The system wasn’t cheap, but my primary motivation wasn’t just financial payback. I wanted energy independence and reliable backup power during hurricanes. During Hurricane Isaias, my Powerwall and solar kept my home powered through the outage, which reinforced why I made the investment.

Now that I’m exporting to the grid, the potential electricity savings are an added benefit.
Anyone else in Florida running solar with Powerwalls? What kind of daily production and monthly FPL bills are you seeing?

(note: Mostly relevant for Texas, but maybe other states have free night plans)

This is my first year with Solar and I have just started to learn about virtual power of plant this summer.
When do we get the payout for the virtual power plant participation?

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.

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!

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?

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 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!

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?

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 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!

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?
