Charged my Tesla, 29kWh, but emphases only showing 8.3kWh consumed. What am I missing?

Today, I received a notification from the Tesla app requesting me to schedule an appointment as my system requires service. Upon checking the app, I discovered that it was indeed not generating power. I proceeded to schedule an appointment, but it’s a week away.

This situation raises the question of whether there’s a way to make a claim if the system fails to generate the specified amount of power as outlined in the contract.

Thanks!

Homeowner with CoServ. Summer electric hits $600+/mo (pool, two HVAC, two EVs, 2-story), 7-year-old roof since we bought the house 7 years ago.

Got a Tesla quote lease = $50K buyout at year 5, for $391/mo (+yearly increase til buyout). This is for 2 powerwalls with a 25.20 kW system. Other dealers local cash quotes around $60-65k for similar. Low mortgage interest so opportunity math says solar lease+invest more cash beats upfront cash purchase. If others regret their lease

Three things I can't get clarity on:

A) Texas rates went up 5.7%/yr from 2020-2024 but US 25-yr avg is 2.85%. All this AI/data center demand, is it actually going to keep pushing 5%+?

B) Feb 2021 freeze outage still messes with me. Powerwalls feel like cheap insurance against pool plumbing freeze ($3-15K busted pipes) but our actual outage history is mostly 5-min blips.

C) We are in top 5 of hail claims. 2023 was about $7-8B damage across DFW. Am I just putting this money for a piñata on my roof? :-) "Hey that powerwall saved our pool equipment but we just got hit with a baseball hail rock a month later!"

If you've been through a major hailstorm WITH solar, is it not as bad with Tier 1 panels even when the gof ball size ones do eventually hit?

I have 20 x 410w Mission Solar PV panels already and plan to add 2 or 3 x 425w mint used (less than a year) panels (also Mission Solar). Can my single Tesla inverter (not a powerwall) handle that? Or will I just be wasting my money on those 2 extra panels? What inverter should I switch to instead?

Hi, I had my powerwall 2 for about 3 years and just got a model y less than 2 months. I tried looking on the app for charge on solar, but I don’t see it. I set my location for my house same address on the solar side of the app and also reset my app by deleting it and reset the car screen and nothing. I just have the mobile charger and that should work as my neighbor showed me she got charge on solar with the mobile charger. I don’t know what else I can do I messaged Tesla on the app and they just refer me to my installer and my installer said I need to put the circuit on the same outside panel as the battery but from other post that’s not true. Thanks

Anyone else's power wall offline ?

Hi all, I've been having issues with my APC ups unit with power switch overs from grid to battery and back to grid. My research on this sub led me to believe that I need to adjust my maximum frequency shift to 2.5 (for 62.5Hz). However, when I finally got through the Tesla One app to make the adjustment I found that the setting was already at 0.2 (for 60.2Hz). This leads me to believe that my Powerwall 3 may not have been the cause of my ups problems, but regardless I raised the maximum frequency shift to 2.5 (for 62.5hz).

Is it possible my PW3 battery may have been damaged from over charging because of a Maximum Frequency Shift set way too low from the installer?

Any recommendation on further actions to keep my APC 1500 ups functional?

I wanted to share a system I've been running that automatically charges my Tesla using only solar + battery surplus — zero grid import.


How it works:
- Every 2 minutes, it reads solar generation, battery SOC, and household load
- Formula: Available Power = Solar Gen + Battery Discharge(max 5kW) − Household Non-EV Load
- If available < 200W → pauses. Otherwise sets charge current 5-32A
- Integrates Alpha ESS (solar/battery) + Tesla Wall Connector via Home Assistant


Real example from my setup:
☀ 2,525W solar + 🔋 5,000W battery − 🏠 312W house = ⚡ 7,213W → 16A charging at $0 grid cost


It saves around $300+/year vs peak-rate charging and requires zero touch — set it once and it just works.

Happy to answer questions!

I think the car AC/Heat needs a bipolar mode. Ever find yourself changing from low to high frequently? Sometimes you’re cold, sometimes you’re hot.. You just can’t find a balance.

Introducing Bipolar Mode! A customizable mode that adapts from low to high and changes throughout your ride. In the customizable menu you can change the way bipolar mode operates, setting a max and a minimum, as well as timing intervals, and frequency.

I personally want this to be added ❤️.

Background: Have a lakehouse in Texas where I installed solar. Leased an 8.4 system with only 1 Powerwall (mainly for price, but also didn't know I would need more). We really wanted some backup in case of outages (which are somewhat regular) and didn't want to pay for a generator and propane to run it. Since we won't be there as often, any energy credits will be good over time.

Don't have any complaints about the process through installation, as we had good communication and a good crew. It seems the power wall won't last for more than a couple of hours if we use the AC during an outage. Tesla won't add to the existing lease, and any expansion pack would cost over $ 5,000 for installation, as if it were a new PW3 install through Tesla Solar.

From start to finish, it took a couple of months to get the system up and running. I've had the system running for a full month now. In that month, it seems I have returned 81.46kWh to the grid. (.0059968cents) Normal electric costs are $0.1412698 per kWh, not including the $40 per month service charge. The house averages around 600kWh per month.

I'll still have to pay the $40 per month, but I will get a $4.88 credit this month for electricity later on. I basically saved $72.75 from last month's bill by having solar produce the electricity. Lease payment is $160 with the usual terms.

I figured the lease worked better since Tesla is responsible for repairs, etc., and because I didn't have the cash or money for a system purchase. I also thought I could lease again after 5 years to keep a low payment and Tesla would still be responsible for the "older" system and maybe Tesla will let me add an expansion pack or 2 then if I re-up (doubtful). After 10 years, I imagine I'll be in a position to purchase. The 5-year price is still too high given the quoted amount.

Did I mess this up? Is saving $80 a month for what amounts to $200 in costs worth it just for the peace of mind of having backup for a couple of hours? I'm not that concerned about the environmental impact I may be helping with by having solar. I might have just set myself up to pay more each month for something that won't help me that much or get that much use. So, did I make the right decision?

Thoughts? Ideas?

We have a solar system with a Tesla battery, installed a year ago. We live in Northern California and just read about possible Public Safety Power Shutoffs later this weekend because of strong wind forecasts. The chance seems to have lessened since yesterday, but I'm still assuming it's an outside possibility. We are not in the most likely area for a shutoff, but I'd like to at least be prepared. So, as someone who is still learning about how to prepare for a possible event... do I adjust the backup reserve? I have Storm Watch enabled, but I don't know if wind storms/PSPS count as "severe weather events."

With two Wall Connectors and proper load sharing, both cars can stay plugged in overnight while the system manages the available power.

The second charger does not magically make electricity cheaper or double the home’s electrical capacity. It just makes the overnight charging window easier to use.

I've got 50 total Solar Panels. 40 enphase panels have been going for 12 plus years with no issues. 10 Tesla solar panels have been operating since October 2025 along with three Tesla PW3s. My old 40 panels were tied into the Tesla system in October of last year and running fine until today. Today my production has been 80% down from what is normal. Any thoughts on what is going on?

Hello, I’m in the process of getting HOA approval for solar panels on my roof and a few neighborhood concerns have come up around the aesthetics of the panels. I’m wondering if anyone has any real world experience with things like solar glare or anything aesthetic related? I understand that Tesla puts reflective coating on their panels, but does it work? Thank you in advance.
