    PSA, big recall for Schneider Electric (includes Square D and QO load centers)

    The HOM breakers are 1" thick while the QO breakers are 3/4" thick. But at least some HOM panel models also support plug-on neutral breakers. The panel Tesla installed for me does, for example.

    Caution - Annual Service - Car power-down - GPS issue

    If you read back through the pages of this thread, you'll see descriptions of the cable that I made for facilitating a firmware update in the Garmin GPS sensor on 2.x cars. I have loaned that cable to many owners. Now, however, due to failing health I won't be able to handle sending out the...

    How long between inspection and PTO? [various areas]

    Yes, bank account is the method required for Tesla's automated payment system. That did not work for my brokerage account, hence the CC. 3/10/22 - full payment 5/13/22 - interconnection request sent to PG&E 5/19/22 - PG&E approved PTO

    How long between inspection and PTO? [various areas]

    Is your system operating in self-consumption mode? If so, has it been performing as expected? That was my understanding as well. I paid the whole about by credit card over the phone, but that may have been unwise because there was substantial additional delay requiring multiple phone calls...

    New Powerwall Advanced Options [Toggles for charging from and discharging to grid from powerwalls]

    My interconnect agreement for NEM2 does not include that checkbox, but the Application Summary document that PG&E emailed back upon receipt of the interconnect agreement includes for both Powerwalls the line "Charging mode: No Grid Charging".

    CPUC Nem 3.0 discussion as it relates to Energy Products

    We are in Sunnyvale, so near the south end of the bay but not near the coastal ocean. We may be more temperature tolerant than some, and we do have a whole house fan to help move the heat out of the house in the evening. Today outside is 91.4 and inside 71.2 without A/C. Inside will go higher...

    Powerwall: Three-phase house

    Best charging practice/set up for a Roadster (1.5 in North America in specifically)

    I have Roadster VIN 33 which came with the same original HPWC. I bought a 50A electric stove cord with a NEMA 14-50 plug at Home Depot and installed it in the HPWC. (For my location, I routed it out the top.) I had previously installed a 14-50 socket in my garage for another EVSE.

    In a pinch you could harvest a switch from the unprogrammed spare key.

    How long between inspection and PTO? [various areas]

    Followup to this post of mine on 4/24: I called on 4/29 and got confirmation that FinOps had completed the required action, so the CSR was going to contact the interconnection team regarding submission of the request. On 4/30 and 5/2 I received emails about new documents in my account to sign...

    Caution - Annual Service - Car power-down - GPS issue

    Nevermind that Tesla could have fixed the date problem with a simple change to the firmware in the VMS itself, which they should have applied without charge.

    Caution - Annual Service - Car power-down - GPS issue

    I don't think anyone at Tesla has a cable like the one I made and have loaned to many owners. The cable that some Tesla service centers might have is one that connects to the Molex connector where the GPS sensor hooks up to the wiring harness behind the left front wheel. Mine hooks up to one...

    Heat generation from Powerwall+

    It's captive so you should feel it be loose once it clears the threads.

    Heat generation from Powerwall+

    Just to the right of the button you found to push is a thumbscrew that can act as a lock to keep out prying fingers. Mine is unscrewed but yours might not be.

    Increasing Home Insurance with system installation cost?

    I have my home insurance with Wawanesa in California. They seem to have specific underwriting for the Tesla Solar Roof based on the percentage of the roof area that is active tiles. My premium did increase.
  18. slcasner

    Should I add a 3rd Powerwall in California?

    As others have mentioned, the reason for the inverter is to drive the compressor motor at a variable speed. As an example, the Tesla Roadster motor is a 3-phase, 4-pole AC induction motor -- a design invented by Nikola Tesla, hence the company name. The frequency of the AC waveform produced by...

    What inverter status are you looking for? You can get the parameters of each MPPT through the /api/devices/vitals resource on the gateway, for example.

    Using a Credit Card or Paypal to pay for TESLA Solar

    I paid by credit card. As a consequence, my account was stuck in limbo where the billing department knew that the balance had been paid but because I didn't go through the automated payment system my account page still showed the payment step as pending. Critically the account did not get...

    Heat generation from Powerwall+

    Is there a microswitch that detects the cover being open, and if so, did that cause the fan to shut down? If so, leaving the cover open might not allow the unit to cool itself properly. (I'm just speculating here; I have not looked for myself.)

    Daily reset/shutdown of my Powerwall+ and/or Inverter after coolant top-off?

    I assume DC input is needed for the test. For my system it is a pretty small dropout.

    Daily reset/shutdown of my Powerwall+ and/or Inverter after coolant top-off?

    I believe it is an inverter self-test that is mandated by the standards.

    CPUC Nem 3.0 discussion as it relates to Energy Products

    In N.Cal, we only need A/C 10-15 days each year. With the TOU rate, we run the A/C after midnight (off-peak) to pull the inside temperature down to 69° (good for sleeping) and then let the inside temperature rise during the day with the windows closed until the inside and outside temperatures...

    Mid day point release update (22.9.2)

    My system had a 10:45AM upgrade from 22.9.1 to 22.9.1.1 -- no idea how that is different from 22.9.2. Once again it caused my monitoring to stop, perhaps because reauthentication was needed.

    Low Solar Production and Peak vs Rated

    But the currents are equal, too, so that suggestion isn't a complete answer, either.

    Gateway password change doesn't stick

    I changed the password on my GW2 when it was installed last November and the changed password continues to work and has not been reset. Several firmware updates have occurred since installation. EDIT: Specifically, this is when logging in to the GW2 over the hardwired or wifi connection to my...

    V2G support in Backup Gateway/Switch

    I am one of those Roadster owners. The inverter in the 2008 Roadster was bidirectional because it was a digital reimplementation of the A/C Propulsion drive system. The A/C Propulsion drive system was inherently bidirectional and was, in fact, operational in some V2G experiments using several...

    V2G support in Backup Gateway/Switch

    I agree. I was just making the point that a V2G implementation would at least need to guarantee that it would stop sending power to the grid if the grid goes down. To the extent that the system is serving as V2H as well, then indeed what you want is to continue operating in isolation from the...

    V2G support in Backup Gateway/Switch

    A V2G implementation would require the ability to switch off (isolate) if the grid goes down.

    How long between inspection and PTO? [various areas]

    I'm in the same boat, or a similar one. I paid in full by credit card[1] on the day payment was requested. The phrase used by the CSR in my case was "waiting for the billing department to send an invoice indicating paid in full" to the department that handles utility interconnection requests...

    New Powerwall Advanced Options [Toggles for charging from and discharging to grid from powerwalls]

    Need to be careful about the terminology. The Powerwall+ integrates the solar inverter with the Powerwall, and the processor board in the solar inverter can perform the same supervisory functions of the processor board in the gateway. But the contactor (relay) and some sensing functions of the...

    Can't authenticate for Tesla account [from older android device]

    My Pixel 2 XL is running Android 11, which is stated as the last version available for this device. The phone has been running the Powerwall Monitor app just fine for several months until two days ago when the authentication problem arose, so I wonder what changed. Just now, as I was poking...

    Max rebate from SCE at true-up?

    You are a net producer only if you have sent more kWh to the grid than you pulled from the grid. Just having a negative year-to-date energy charge is not sufficient if you are on a TOU tariff such that the kWh you sent to the grid were priced higher than the kWh to pulled from the grid.

    Can't authenticate for Tesla account [from older android device]

    Good point, but I think the new version of the app was still happy with this phone because it does start up and go through the authentication steps. I think the recent posts here about older phones were regarding iOS devices.

    Faded Tiles on Front of Home

    It looks like spray paint to me, too. I wonder whether some accident during installation caused a scratch or mark across the various surfaces, to the team used their black spray paint to cover the problem. But after time the spray paint has faded.

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    Following up on my earlier note. I did receive Timothy's OVMS and modem. When I tested them at my home (Sunnyvale) about two weeks or so after the installation at his home (Santa Barbara), the RegistrationDenied problem did not occur. This might be explained by a different location (so...

    Roadster featured in Cyber Rodeo

    The original EP2 interior was all beige (or tan), just like my #33 still has. I have early posters and photos of EP2 that look just like my car. Did you happen to notice that EP2 has a port behind the front wheels feeding into the inset area under the doors? Martin told me how this improved...

    charging model 3 in self powered mode without draining powerwalls?

    I've seen a couple of posts about software to run on some computer to monitor the solar output and use the car API to adjust the charge current accordingly. I have not taken the time to work on this for myself yet. It is not necessary to adjust the charge rate to match the solar output unless...

    charging model 3 in self powered mode without draining powerwalls?

    This way the energy going into the car has gone into and back out of the Powerwalls which means 10% loss. It is best to use the excess solar directly into the car during the day if you are home and can manage the charge rate to consume most of the solar and just let a little bit go to the...

    22.1.2 Update

    My system is on 22.9.1 and in pre-PTO self-consumption mode. Since three days ago I'm seeing about 1.1kWh/day additional grid usage (whereas before it would vary from 0.0 to 0.3kWh/day).

    Did you request utility permission before installing L2 charger?

    You're right. In both of the instances where I participated in causing a transformer to overheat and fail, PG&E came out promptly to replace the transformer. At the RV campground near Yosemite this required traveling some distance from the nearest service yard and working in the middle of the...
