    Powerwall Reset During Grid Outage

    I had a few hour power outage yesterday where my Powerwalls immediately took over with no interruption. At that time clouds were variable and solar was intermittent. The Powerwalls were slowly being discharged and not knowing when the power would return, I began removing non critical loads from...

    Tesla Service Back to the Original Hand Holding of the Early Days?

    Probably not, but ... A few weeks ago my car started complaining about a HV Fuse that needed replacing. Looking over TMC it appears the earlier cars had a battery supported fuse with a 10 year life. There is nothing in the car to determine if the battery is good or bad, just a clock at...

    Who is Your PW Registered Retailer?

    I was poking around in the PW API site_info and honed in on the retailer tag. Mine was listed as CleanPowerSF. I don't live in SF and had to look them up on the internet: https://www.cleanpowersf.org/ So I am guessing Tesla just used this as a default rather than leaving it blank. Anyone else...

    Charging Stopped Notification

    For the last several months I have often received a notification from the Tesla mobile app that my car has stopped charging. Its a bit random but usually within the first few minutes of charging. I have a Gen 2 WC and it has been installed for over 6 years. I have had it running at 72 amps and...

    Tesla Solar Roof Local API

    Is there a local API for the Solar Roof like there is for the Gateway? I know that the app has a separate panel for the Solar Roof from the GW. I have also used the GW local API but all solar is bundled in the site/solar returns. I have three solar sources (3 invertors) and I wanted to see if...

    Virtual Powerplant Payment Address Confirmation

    Today I got an email addressed to "Hi Mohammed" (not my name), to validate my address in my Tesla account because VPP payments would start after the first of the year. Anyone else get this email? Did they use your correct name?

    NEM-PS Annual True-Up Calculation [PG&E example]

    I was having difficulty in understanding where all the elements came from in my annual true-up bill and reached out the both @miimura and @Redhill_qik for some insight. From our discussions a document was created that is copied into this post. This document explains the factors that determine...

    Frequency Response During Power Outage

    Just a quick observation: Today I had an unscheduled power outage just before peak at 3PM. Powerwalls (2) were at 100% and solar was being returned to the grid. There was a quick pause in power (a few none UPS devices restarted and one needed manual restart). Frequency jumped to 60.3 which was...

    Time Based Control Getting Smarter?

    Today I caught Time Based Control altering a decision in what appears to be a near term solution. In the past I have seen it go down with the ship. If it's analysis for several days indicated a strong pattern it would stick with it. Last night it was hot and we kept part of the AC running most...

    Solar Roof Showing 0kW Output on App

    Today I wandered over the Solar Roof portion of my app to see how it was performing. I noticed the graph of energy created today but then noticed that the current kW value was 0. This is a solar roof on a Delta Inverter. I have two other solar systems measured by CTs on my PWs along with the...

    Mass Service at Rocklin SC 12/29-31/21

    Yesterday I attended the mass front ball joint lubrication and inspection service at the Rocklin service center. This was for selected Model S/3/X that had not had their ball joints inspected and lubricated from other visits. It was like organized chaos with service people running up and down...

    Older Cars Charger Priority?

    The other day I went to the Hard Rock Hotel in South Lake Tahoe. It was packed with never more than 2 stalls free for more that a few minutes. I arrived with about 30% SoC and got around 50 kW rate as I was paired with another X. After about 20 minutes that X departed and my rate climbed to 110...

    Discrepancy in the Tesla App After a Few Days

    I did a screen capture of my solar production at the end of the day and this is what I got. It was also verified within 2% using the value of the three inverters. A few days later I did a screen capture of the same day and got a hugely different value: And if I download the data from the...

    Delta Inverter Communications

    The Delta M4 that Tesla supplies only seems to have Bluetooth to talk to their little gateway box you need to plug into a ethernet cable. Delta says the M series can have Wi-Fi and ethernet as an option. I am looking for a way to see what this inverter is doing vs only the aggregated value from...

    Backup Camera Disappears when Touching UI on AP1 Cars

    I don't have too much hope any of this will ever be resolved. A number of years ago Tesla made a change in the UI where if the backup camera was showing (default when you put the car into reverse) any touch of the screen would cause the backup camera to disappear. This is a huge safety issue. I...

    Storm Watch for 1/25/2021

    I think storm watch just kicked on for El Dorado County. I have it set in the app but its not showing as on. However just a few minutes ago my power flow from the grid just went to 6.7 kW to the PWs and they are charging. Solar is only putting out about 2.5 kW.

    My Small Solar Roof Project

    Remote Solar to Powerwalls

    I have put a reservation in for Tesla solar roof to go on a remote building that is about 200 feet away from my main panel and existing powerwalls and other solar inverters. That circuit is currently fed by a 50 amp breaker and has almost no load on it. It's in a barn with a few non used power...

    1.46 FW and Standby Mode

    Last night my PWs got 1.46 of the firmware. I have been running in Cost Based mode at 50% reserve for months and except for one event last week all seemed to be good. PW will charge to 100% during the day and flip to discharge at peak (3pm). Generally finish peak around 75%. Today the powerflow...

    Sure Start/Soft Start Question but Still Grid Connected

    I am fully aware of the need for a Sure Start/Soft Start when the Powerwalls are isolated from the grid and powering my home for starting certain high current devices.

    Southland and LV Superchargers Offline?

    On another thread I saw someone post that the California superchargers were off line to prevent people clustering for COVID-19. I went into my car and sure enough all the So Cal and LV chargers don't show the occupancy. Not sure if that means they are offline or not. The Nor Cal ones north of...

    Glad my car charger was not backed up

    When I did my PW design I purposefully excluded backing up my Wall Connector because my regular charging rate (about 18kW) and my capacity (26kWh) would overtax my PWs. So I left it on the grid side panel. Last night my car was scheduled to charge at midnight and needed to be charged from 24%...

    Why are we limited to selling solar energy in real-time only?

    It's probably my confusion and I have not read the restrictions yet but I am not sure why we are restricted to only selling back solar power while we produce it. It would seem we should be able to save our solar power in the PW and then play it back anytime during the day we want to just as...

    FWD Opening Clunk

    On both of my FWD there is a distinctive sharp clunk or snap when the doors are opening. It happens about 1/2 up and I have confirmed it is in the middle of the two doors vs the main hinge at the top. The SC thought it was some trim objects but I am suspicious as it happens on both doors. They...

    Display Error or Time to Rebalance?

    Charged to 98% the other day since we were eating lunch at a slow restaurant. This should have resulted in 98% of my 90 kWh hour battery or 88.2 kWh. A few miles down the road I captured a screenshot of the trip and here is what I got: Doing the math: 88.2 kWh - 3.8 kWh = 84.4 kWh...

    Clunking Falcon Wing Door

    Recently I have noticed a rather distinct clunking sound that appears to be coming from the passenger FWD. It's not loud and only appears on uneven roads at lower speeds (ie < 20mph). I opened the door slightly (about 6") and the sound seemed to disappear on multiple tests. It kind of sounds...

    Both Key Fobs Not Working - Fixed

    Last Friday my key fob worked great. I was on 2019.12.1.1 for a few weeks. Going into the garage with my auto open doors set to on, the fob of course opened the door which I pushed closed. This happened once more and then the car decided not to do it again as usual, or so I thought. Later that...
