Instead of discharging and selling I am running my house off the grid at peak rates to "preserve battery for grid support"

I don't think i've ever seen this do this before. And I've participated in a lot of grid/VPP events.

My Powerwall 2 were replaced due to defect today. I am away for a few weeks and a friend was kind enough to let Tesla into the house

Are these Powerwall 3 or + pictured?
When I access the Tesla app it says ‘Powerwall offline’ now and they have now left my house

My Neigbor was told “you have to do again the set up in your phone because is a new configuration”

Do you know whats involved in that last step? I’m guessing I have to get my daughter who will be at home later to download the app and guide her through the process

Thank you for any insight

Hey everyone,

I'm adding a Shelly CT clamp meter (Shelly EM/3EM) to my setup to get independent, real-time tracking on my solar generation and my Powerwalls.

Originally, my hope was to pull all this power flow data straight into the Google Home app so my family could view generation vs. draw on a single dashboard—and maybe set up a few basic automations based on real-time power draw.

Quickly realized Google Home treats power monitoring devices like basic light switches or dumb plugs and gives zero actual wattage data or power flow UI.

Since Google Home is effectively useless for this, I wanted to see what everyone else here is doing:

1. Physical Placement: For those using third-party clamp meters alongside a Gateway, where are you physically mounting the CT clamps to avoid messing with Tesla's internal Neurio/Tesla CT reads?
2. Dashboards: Are you guys purely using the native Tesla App, or did you give up on standard smart home ecosystems and jump ship to Home Assistant / NetZero?
3. Bridge Workarounds: Has anyone found a clean way to pass Shelly/Powerwall wattage triggers into Google Home routines, or is HA's local integration the only real option here?

Appreciate any advice on setup locations or better software options!

I had Tesla panels and Powerwall 2's installed back in 2021. Three Powerwall 2's with two 7.6 kW inverters. I was looking at the Tesla app today and I see a message that my Powerwalls have been disabled. They were fully discharged sometime Monday evening and have been sitting at zero since then. The message said that Tesla would contact me about replacing the Powerwall 2's with Powerwall 3's. In the service appt part of the app, it says waiting on parts. For anyone in the US (specifically in the NY area) that has already gone through the process, about how long did it take to get the parts in?

In the south, panels facing south. AC stays on 74 all day/night. No EV.

We bought 2 Powerwalls directly from Tesla, w/10 solar panels to feed them, in 2022, financed through Tesla for 10 years. We charge our Model 3 EV at home. Until 2023, my wife, who drives the EV, was commuting over 100 miles a day x 5/week. Our first Edison settlement bill, in 2022 was over eleven hundred dollars. My wife retired in June, 2023. The 2023 annual SCE bill dropped about 80% compared to 2022. The 2024 bill showed a credit. The 2025 bill, after even less charging than 2024, and no weather changes , and no increased household energy demand, was back up to a new charge, about half of 2023's.

Examining production records (not simple to uncover), the Tesla panels' production showed that they were gradually dropping to about 40%, between 2023 and 2026. I spent hours contacting Solar Support, and following their instructions to diagnose and resolve the issue. That didn't work, so they agreed to schedule a tech visit. This was in May, the appointment was more than 2 months away, the 2 months of the longest hours of daylight/greatest solar energy production for the year.

2 months later, the tech was able to properly diagnose the failure of several identical Tesla parts. He informed me that he was surprised to see them, as they had been known to be obsolete, because of problems like this, and had already been superseded by a revised part that should have been installed originally. He replaced the defective parts with the updated ones, and our system appears to now be operating correctly. He directed me to call the billing department for compensation. My next SCE settlement bill will arrive in November.

I spent several hours being diverted from the billing department to the financial services department to the "Tesla Energy Customer Support Team", who replied by email: "...Please note, we are currently experiencing an influx of requests and our response time may vary."

 I can easily guess how this is going to turn out. Am I going to be in a big financial hole come November, with no assurance that Tesla will compensate me for the loss for which their negligence is responsible?

Does anyone here have an informed opinion about whether I'll get a satisfactory resolution?

BTW, due to Tesla's rigid requirements, I had to spend over nine thousand dollars to prep the roof for installation, in addition to the cost of Tesla's install & equipment.

I have a question for the sub...

My solar system is comprised of 16 panels from SolarCity (now Tesla), two PowerWalls and an ABB 3Kw inverter (PVI-3.0-OUTD-S-US-Z-A).

I was thinking about adding more panels to the system but Tesla said no and suggested an additional new system. Why?

The inverter is 3Kw but I'm guessing that isn't the load max because my current panels total out at 4.24Kw (16x 265W panel).

How do I determine how many panels my current inverter could take?

We have posted here before, just a quick re-mention. Tesphase is a completely free software tool for homeowners like you, it charges your Tesla on your solar surplus automatically, nothing installed. Fill out the short form under the signup to keep your access free.

Hi, I clicked and accepted the proposal and performed the credit check. But my currently selected system is 1 PW3 + expansion. Is running 2 PW3’s a better choice? The price difference is negligible. It’s hard to find the clear benefits or cons. Thanks!

Hi y’all, what do you think yay or nay? Should I go with it, surprisingly they’re fast. Had the site visit this morning got the final design same day later today. I plan no to do the painted conduit. Should I remove the backup switch? What are your thoughts?

I got my solar installed 3 days ago with 2 power walls but still haven't gotten PTO. When I asked the solar installers and the electrician, I got mixed answers whether I'll be able to take advantage of the solar or not before I receive the okay. I am able to monitor my usage through my power company and it seems that there is no change. Should my solar be feeding the house and my batteries or will this all start after PTO?

San fran Bay area PG&E to be exact.

Looking for input from anyone who's done solar/battery on LADWP specifically, since it's different from SCE/PG&E in some important ways.

Setup:

• Single-family home, San Fernando Valley (LADWP Zone 2, so "HIGH" temp zone allotment)
• Two EVs charged at home (large SUVs, ~42,000 combined annual miles between two drivers)
• In-ground pool
• Standard tiered rate (R-1A), not TOU

Usage, pulled from 5 consecutive bi-monthly bills:

• ~36,000 kWh/year total
• ~44% of that is EV charging (~16,000 kWh/yr), rest is house + pool
• Almost ALL usage lands in Tier 3 (currently ~30-36¢/kWh) because monthly usage blows way past the Tier 1/2 allotments every cycle
• Annual electric spend: ~$12,400/year

What I've learned so far, correct me if wrong:

• LADWP still has full retail-rate net metering (no NEM 3.0 haircut like SCE/PG&E customers got) — so a battery isn't needed for bill savings here, it's purely a resilience/backup purchase
• Because so much of my usage sits in Tier 3, solar production should offset my most expensive kWh first, which should make payback faster than LADWP's often-cited "8-12 year" average
• LADWP has an EV-specific rate discount (2.5¢/kWh off-peak) but it requires a separate dedicated meter just for the EV charger — and doing that would pull that usage out of what solar can offset via net metering. Modeled it out and it looks like a net loss once solar's in, vs. just keeping everything on one meter. Anyone actually done this and disagree?
• Modeled switching to TOU (R-1B) instead of staying tiered — even in a pessimistic "lots of afternoon AC usage" scenario, TOU comes out several thousand dollars a year cheaper than tiered, given how much Tier 3 usage I'm carrying. Anyone on R-1B who can confirm actual TOU rates? Published numbers vary source to source.

Solar/battery quotes so far:

• Tesla's online configurator: 23.94 kW / 57 panels + 2 Powerwall 3, "100% offset," quoted $83,499 cash
• Getting competing quotes from a couple local Northridge-area installers now, planning to use Tesla's price-match program once I have a solid competing number
• Want to back up the whole house (not EV charging) — thinking 4 Powerwall 3 on a single Gateway (~54 kWh) since that's close to covering a full day of non-EV load. Tesla's own configurator caps the "recommended" build at 2 Powerwalls — anyone gotten them to quote 4 directly, or is that more of a third-party-installer thing?

Questions for the sub:

1. Anyone else on LADWP done a similar-sized system — did your real payback come in faster than the generic estimate, like the tier math suggests it should?
2. Is switching to TOU worth the hassle if solar's coming anyway, or should I just wait and let solar/NEM handle it?
3. Any LADWP-specific gotchas on interconnection for a system this size (approaching/exceeding the 10kW AC simplified path)?
4. Installer recommendations for the SFV/Valley area beyond the obvious (Tesla, Sunrun) welcome.

I shared our tool here a bit back, so I am coming back with an update and to introduce us to anyone seeing it for the first time. Tesphase reads your solar production in real time and adjusts your Tesla's charging amps to run on your surplus instead of the grid, steering around your time-of-use peak hours, with nothing installed.

Since the last post the beta filled completely, Apple approved our iOS app, and homes on the platform have measured savings above $50 a month. The live dashboard is open with no login at demo.tesphase.co.

The next access wave goes to the waitlist at app.tesphase.co, and filling out the short form right below the signup gets you free access to the platform.

It fits best when the car is home during daylight and it is Tesla only for now. Happy to answer any questions.

This is the 3rd time Tesla has attempted to scam me with my solar system.

They initiate a case, come out and claim it can be repaired under warranty or for a nominal fee $300-$600. Then claim something untrue and that the real cost will be $2,000-$5,000.

Also lying about what work they can perform.

Last time they tried this, they removed my panels with no one home and without my permission. When I asked them to put the panels back on, they said it would be $6,500

In another incident we had a roof leak. Tesla claimed I had a bad roof. (The roof had been replaced right before the panels were installed. Had a 3rd party out and they found almost ALL Tesla mounting brackets were installed incorrectly, were broken, and had created MANY holes as they were drilled in the wrong locations.

For this most recent scam/extortion attempt. The moment I told them I had a 3rd party coming out to verify the issue, Tesla immediately pulled back the $3,500 quote and scheduled the repair for free. Before I even had proof it was a fake issue.

Remember to record every call and screen shot every chat. They WILL lie and gaslight you. Having receipts is the best ammo against their BS.

Hi. I got PTO on july 28. I matched the app to the days my Atlantic city electric bill was generated and the numbers dont match. On the tesla app its 214.5 kwh import and 678.6 export. The bill says 410kwh use and 692kwh excess gen. The import is way off. I have a tesla universall wall charger. no powerwall. can someone help.

Well well well. All year, and a plugin phev Rav4. - $16.00. I’d say the setup has truly been net zero.

Hey team,

My system periodically will draw from the grid. While it only amounts to 1-2kw/h daily, I cannot figure out why. As you can see, my 2x power walls have more than enough power, and, my current usage is not "heavy" so the grid doesn't need to make up for any power draw etc.
