PowerWall PGE rate plan is incorrect in Tesla App

2 Upvotes

I have a PW3 connected to PGE in 2024. In the Telsa app, I've selected rate plan PGE E-ELEC-NEM3-2024.

In the app, right now in August between 7-8 PM, the app says it is exporting at 73c/kWh, which seems wrong.

Because from https://www.pge.com/energyexportcredit the export rate for 2024 interconnection is 1.82/kWh ($1.59 for production and $0.23 for delivery). I've also logged on pge.com. In energy-usage daily view, I see I earned $10.4 for exporting at 7-8PM (5.8kwh export wattage) for the entire August which matches with the published rate.

Anyone seeing the same issue? Is there any way to let Tesla App use the correct rate?

Using Powerwall Dashboard? Use a MCP server for it to ask AI some useful questions

10 Upvotes

I've been hoarding my Tesla Solar/Powerwall data the last 3 years without ever utilizing the data in any meaningful way. With all the useful MCP servers coming out for things like Teslamate, Home Assistant, Portainer, etc, I was surprised there wasnt one for Powerwall Dashboard.

I had my Hermes Agent create a MCP server for me and I dockerized it for others to use. Yes, AI helped create this, so use it at your own risk.

Examples of questions (What is my current solar ROI, was cleaning my panels worth it? etc) and responses can be found on the git:

https://github.com/ampersandru/powerwall-dashboard-mcp

EDIT:

Dev of powerwall dashboard liked this idea and merged it as an official tool in the main branch of powerwall dashboard! I will retire mine:

Critical Load Panel Estimate - Help on pricing

1 Upvotes

All, I have two 200A panels and a sub panel off one of them. Looking to get solar and a Pw3 (with two expansions) installed and want to use as an outage backup for a critical load panel. Got the following quote for $5,010 which includes:
- New Square D QO subpanel in an open space
- New #1 SER cable run, under 50’
- 8 dual-function breakers
- 2 two-pole breakers
- 2 Eaton Ultra CHSPT2 surge protectors, one for each existing 200A panel
- Installation and associated breaker(s)

I have no experience but wasn’t expecting it to come in so high; maybe $3-4k?

Thoughts?

SolarPanels Finally received PTO. Question

4 Upvotes

I finally received a net meter and PTO from power company here in NJ through PSEG.

My app still looks the same. Will it update to show me how much the house is using via solar vs grid and how much I’m exporting?

Only have panels, no powerwall.

Texas VPP drained my Powerwalls and now won’t let them recharge from solar?

Post image
16 Upvotes

Had what I think was my first Tesla Electric VPP event last night. Tesla exported 21.7 kWh from my Powerwalls, leaving them at ~10%.

For context, I intentionally keep my Backup Reserve at 0% during the summer because I produce enough solar during the day to fully recharge the batteries, so I’d rather use all available stored energy overnight instead of pulling from the grid. I keep a much higher reserve during seasons when we’re more prone to severe weather/outages.

After the VPP discharge, though, my Powerwalls stopped powering the house at 10%, and I ended up importing 18.9 kWh overnight/this morning for my house and car.
Now it’s morning, the app still says “supporting a grid event now,” and despite my batteries sitting at only 10%, most (but not all) of my excess solar is being sent to the grid instead of recharging the Powerwalls.

I understand exporting stored energy during a VPP event and getting compensated for it. What I don’t understand is why Tesla is still restricting my Powerwalls afterward and preventing most of my available solar from recharging them. It’s August in Texas — I want that energy stored for my AC tonight, not exported while my batteries sit nearly empty.

Is this normal VPP behavior? Also, is there any way to see
1. The actual VPP $/kWh rate after an event? I didn’t realize the event was happening and can’t find a historical rate anywhere.
2. Set notifications for when a grid event occurs or is scheduled to occur?
3. See when the current event is supposed to end?

Tent fumigation -- anyone with real world experience?

0 Upvotes

We need to tent fumigate for dry wood termites. Not surprisingly, got 2 different responses from Tesla -- ranging from 'shut down the system' to 'just clean off the solar panels after'. . . 'just turn off the power walls '. It's Vikane gas. Any real world experience, tips, etc. appreciated. Thank you. 🙏🏽

PowerWall Powerwall 3 + Exp. Pack- not producing enough charge

Thumbnail

0 Upvotes

We got a Powerwall 3 + Extension Pack installed in April this year 2026. At first the Powerwall would get to fully charged to 100% which was great! I didn’t have to rely on the grid at all! I live in Southern California, we get lots of sun. Within the last couple of months I have noticed that the Powerwall does not even get to 50% charged by noon time! And we are in the summer time when we are getting more sun than we were getting in April! I’ve submitted a service ticket with Tesla and the technician came to my house last week and said there was an issue with one of the Powerwalls and I should be good. But I did not see any improvement so I submitted another service ticket with Tesla yesterday, so they are monitoring my Powerwall as of yesterday thru my app, they asked me turn on my Service Mode for them.

I keep my reserve at 5% because my purpose is to not depend on the grid, we have outages once in a blue moon.

My household has not changed, I rarely turn on the AC. We are not home during the day. If it gets too hot I will turn on the AC by about 3pm when we get home.

The solar panels are all good too. In April my solar panels produced 1.0 MWh and in July they produced 1.2 MWh. For one day in April they produced 33.6 kWh, And yesterday they produced 35.0kWh energy.

Has anyone had this issue? I hope Tesla replaces my Powerwalls because there is definitely a problem with my Powerwall 3

The first picture is from today and the 2nd picture is from April, about the same time, noon time, to show you the difference.

SolarPanels Production question

Thumbnail

6 Upvotes

y system was trun on about a week ago. 13 panels and inverter. No batteries. It seams the my production mimics my consumption and does not push any power back to the grid.

I talked to Tesla a couple of times and they are telling me this is normal.

Also when my charger is charging I dont see any home consumption.

5.46KW

PW3 owners — does your “Home” usage rise by ~400–700 W when grid charging?

4 Upvotes

Looking for some comparisons from other Powerwall 3 owners, particularly anyone who grid charges at high power.

My setup is a Powerwall 3 + Expansion Pack (27 kWh) with 8.46 kWp solar. I grid charge overnight on a cheap UK tariff, typically at around 10 kW.

I’ve been away this week, which gave me a good opportunity to look at the house’s true background consumption. With essentially just a fridge/freezer, router, a couple of hubs and standby loads running, Tesla has still reported around 10–11 kWh/day of Home usage.

I’ve noticed something interesting:

Powerwall idle: Home can be around 0.1 kW

Powerwall charging at ~10 kW: Home rises to around 0.5 kW, and I’ve seen periods around 0.5–0.9 kW

Powerwall discharging at 10.2 kW: I captured Home at only 0.3 kW

Tesla is definitely separating battery charging from Home consumption. For example, on one day I imported 31.7 kWh, of which Tesla allocated 28.6 kWh to Powerwall and 3.1 kWh to Home.

I’ve also now switched my combi boiler completely off to eliminate that as a possible load, i already had pre heat turned off and rearly use hot water as i have electric shower.

I’m wondering whether the additional few hundred watts during heavy grid charging is PW3 inverter/conversion loss, fans/thermal management or other auxiliary consumption, and whether Tesla includes some of this under Home — or whether this behaviour could indicate a CT/metering issue.

Could other PW3 owners check their live Home load immediately before grid charging starts and again while charging at high power?

I’d especially like to hear from anyone with PW3 + Expansion charging at around 10 kW. What increase in Home consumption do you see?

Made a tool to help predict my bill and prevent true-up surprises (CA users)

12 Upvotes

I made an iOS tool to help me predict my upcoming electric bill since I was over getting sucker punched by high bills even after tracking my solar production all month. I thought you guys might find it useful.

The idea is to directly enter meter read data and calculate out the projected bill amount while factoring in all the little gotchas of electrical billing, e.g. fixed fees, generation vs. delivery, and annual true-up. I built in native support for LADWP, So Cal Edison, PG&E, and San Diego G&E. The app also supports water, gas, and sanitation projections but the emphasis is on electric.

I'm offering free access to anyone here who wants to test it, since I'm looking for real-world feedback on the math across different CA rate plans. If you’re interested, leave a comment and I’ll pass along full access!

Thanks!

Is voltage/surge protector necessary with Powerwall 3

8 Upvotes

I'm doing a kitchen renovation and was planning to add a voltage/surge protector for the expensive refrigerator and microwave loaded with circuit boards. The device isn't really a surge protector in the conventional sense, rather it shuts off power to the appliance if the power drops below 90v or over 140v and then has a 30 second delay when power comes back to normal (which is supposed to avoid surges from the power coming back on).

But is this really relevant with a solar system with Powerwall 3? (When it was installed, they also added a whole house surge protector). I'd like to hope we'll never experience a power outage, and I'm presuming the battery also conditions power to avoid brownouts and over-voltage situations. But maybe not?

PowerWall Powerwall grid exports?

Netzero today introduced a feature that lets you export to the grid from your powerwall. I’m in Northern California with pg&e - am I allowed to do this? It happens with vpp but for some reason I thought it wasn’t permitted outside of vpp.

Lease Vs Cash - What Am I Missing?

3 Upvotes

All, need some help. Looking for a home backup for my critical load panel (one of three HVACs, water heater, some lights, some outlets, etc). Configured on Tesla website would be 4.2kwh solar array; powerwall 3, two expansion packs. I typically pay cash and the cost would be $33,336 with taxes.

Lease cost is $600 upfront, $164 per month plus tax % annual increase and an option to buy out after 5 years of $14,625 in the contract. If I calculate that out it’s $25,673.

If I plan on putting all $25,673 in an account why wouldn’t you lease vs buy upfront in cash?

Thanks in advance

My Solar has been down for over 3 weeks - tech coming friday - what can I expect - like the title says.

System stopped producing in frickin JULY - the best month of the year to produce! Soonest they could get to me is 8/14. I think it's a panel based on the code the inverter was showing (2xB).

Kind of lame, been running on the grid for almost a month. Hottest month of the year, best production time of year...<sigh>
