    Wiki Superchargers Visited

    I did a Supercharger run yesterday. Cleared 19 in a loop between Houston, San Antonio and Austin... I have now completed the "Texas Triangle", although still have a bunch in the DFW area...

    Blog Tesla Plans to Sell Energy to Texans

    I also received the in-app message. Curious to see how it works for others. We have 18 months left on out free nights plan that works very well for us. I’ll have to model the Tesla plan, but I think it will cost more. The unknown is how selling at market rates works…

    Building an off grid Solar Powered (EV charging) Campground

    Really cool thread! When I was a kid, my family owned a ranch that was off-grid and about 10 miles to the nearest power line. It had 2 diesel generators (primary and backup) -- and even with using oil drums buried in the ground as mufflers, you could always hear the generator hum close to a...

    I just went to update the spreadsheet for some new visits this weekend and noticed its now read-only… I had updated just a couple weeks ago. Did something change? Edit: Nevermind… I just found the new supercharging.life site (and really cool that if I logged in via google that it had my data).

    Tesla Solar in Houston & Surrounding Area’s

    I was keeping my answer simple since the free nights plan started a week or so before the install. I did manually disconnect from the grid before PTO (at least while I was on vacation).

    Tesla Solar in Houston & Surrounding Area’s

    That’s the rate during peak / daytime. Once you have Powerwalls installed, you will pull very little from the grid during the day (just a little balancing - we typically see <0.2kWh all day, which costs about 4 cents per day. At night, you pay $0 - so charge your car then. If at least half...

    Tesla Solar in Houston & Surrounding Area’s

    Take a look at the Green Mountain free nights plan - there is no cost for grid use from 8pm to 6am. Excess solar is bought back at $0, but Tesla’s time based control does a great job in minimizing our daytime grid draw. I modeled MP2 and it would cost more on a net metering plan. Our...

    interesting. My install was about a year ago and my only record of the updated design is a pic I took off the hand-drawn pic on cardboard by the lead installer. Never updated on the Tesla Solar page…

    CCS Adapter for North America

    I've also ordered through Harumio, but I added the case. I ordered on Jun 4, but received an email on Jun 8 saying the case was out of stock, with the next batch expected in "around Jun 20" and that I "might only be able to receive them by end of this month"... Based on the recent posts showing...

    Texas owners: Free nights or Net metering

    Our system was spec'd to cover 82% of estimated usage (we had it installed before the house was 12 months old, so we did not have a full year of usage). Now that we've been here for coming up on 2 years, our actual usage is lower that that estimate. For May, the system gave us 89% coverage...

    Texas owners: Free nights or Net metering

    I see your question was answered. Yes, the system exports, but we do so at $0. But the free nights plan still works out to the lowest bill for us. We were just up for renewal and I modeled the 9 months of use we had since PTO using a combination of the Tesla app data and SmartMeterTexas data...

    Texas owners: Free nights or Net metering

    We selected a Green Mountain free nights plan when we put solar and powerwalls last year. Its worked out very well. We have a 16kW system with 4 Powerwalls. Our plan last year was for 12 months, and I just renewed it for 2 years. Our renewal was for the similar plan - "Pollution Free All...

    Brand new Powerwall owner questions (mostly UPS related)

    FWIW... Before we had PTO, I was manually turning off our main grid breaker to go into an outage so we could leverage the solar during the day -- for about a month before PTO. Since the Powerwalls were full for most of the day (they system would flip between all solar and a little PW drain once...

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

    I have 4 Powerwall 2s, plus 2 Tesla inverters. Located in the Houston area with Centerpoint as our TDU ("transmission and distribution utility"). Our REP (ie "retail electric provider") is Green Mountain Energy. Our install was done in June 2021, shortly after PW+ rollouts started. The Tesla...

    Austin Energy and Powerwalls

    I’m in Houston, so different plans…. But I’d recommend putting your rate plan into the Tesla app and then set it to time based control, with the Powerwall reserve set to something like 75% (you could experiment with this — I finally just dropped mine to 50%) The system will then optimize for...

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

    I’m no longer in AZ…. Now in Houston where there are multiple providers with free nights plans. The problem is that they can be tricky to compare. The one we are on has off-peak from 8pm to 6am. Other plans are 9p-9a or 8p to 5a. The other big difference is that some plans still charge for...

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

    You'll still have a minimal bill. I'm on the Houston area and on a free nights plan since last June (our plan was up a few weeks before our install, and we didn't have PTO until Sept 1, so we had a couple months of bills where we had limited solar use). Even without the grid charging feature...

    Tesla App Utility plan configuration: Multiple Peaks, Buy/Sell Behavior, etc

    Yes. Before I the rate functionality, the Powerwalls would discharge during off-peak and drain down to very close to the reserve percent. I was hoping for an option to check a box to "minimize Powerwall draw" for each TOU schedule -- but the more I think about it, adding the rates is better...

    Tesla App Utility plan configuration: Multiple Peaks, Buy/Sell Behavior, etc

    I posted the above in late November. Since other people are saying they are having problems with Time Based Control based on their TOU rates, I figured I'd share how I have ours set up, especially since we have $0.00 buy and sell rates in our plan. Our plan is a "free nights" plan where the...

    Tesla App Utility plan configuration: Multiple Peaks, Buy/Sell Behavior, etc

    We received access to the new settings a couple days ago. working great so far — and fixed the issues we had with the old cost savings mode. We are in the Houston area and have a free nights plan — and we are only charged for peak use from 6am to 8pm. There is no charge for grid draw during...

    16kw system only produces maximum of 11 -12kw (phoenix, AZ)

    thanks. I’m in Houston and had our 16.2kW system installed in late June, with one of the inverters replaced in late July. We received PTO on Sept 1 - since then, max production was 94 and an average of 64 so far this mont (Hurricane Nicholas impacted production for about 4 days — with a low of...

    Tesla app version 4.0.0 has app re design for both car and energy

    I was using the "go off grid" option for a few days before we received PTO on Sept 1... Generally worked well, although one time we lost power for long enough to reset pretty much all devices in the house that react to a power loss (Alexa devices, computers, oven clock...). After that, I just...

    Blog Tesla Plans to Sell Energy to Texans

    Likely related to VPPs... There are no VPPs offerings in Texas today, and I could see them doing something that helps pull from distributed storage (ie Powerwall customers) similar to the VPPs in other states. That would be an arbitrage opportunity -- pay the customers for pulling at a fixed...

    How long between inspection and PTO? [various areas]

    Also Houston/CenterPoint. Our install was done June 23-24, and we received PTO last night (Sept 1) -- so almost exactly 10 weeks. I should have called CenterPoint to check on status and see what the issue was, but never did, partly because just enough updates trickled out to reset my "if I...

    Is Net Metering a Must in Texas?

    We are on Green Mountain's free nights plan (@2tall3ne - you may be able to switch plans with Green Mountain without penalty, although check the rates on the free nights plan -- they went up since we purchased in June and I'm not sure if they have come back down yet since I last checked in early...

    Having used the new version a bit more, I'm feeling mixed on the changes. I like much of the new "look" and appreciate some of the new features. For example, I like how the backup % slider is now just a single one vs having the setting in multiple places (they inverted the process flow...)...

    Drawing from Powerwalls and sending to grid at the same time?

    Thanks for posting this -- really good tip that could be very useful during a long grid outage. For those of us with whole-home backup, I believe all that's required is to turn off the master breaker in the panel -- since that's downstream from the gateway and is simpler than flipping each...

    Is Net Metering a Must in Texas?

    Another Houston-area person here... Our system is 16.3kW (48 350W panels) with 4 Powerwalls (so very similar to @bob_p )... Our install was in late June, and we're still waiting for PTO from CenterPoint (its at the CenterPoint inspection stage, so hopefully soon...). But we've been...

    Hurricane season? Tesla Solar is not ready [because owners can not charge from the grid on demand]

    @niveknow I'm a bit confused. I received the tornado warning around 4:35pm yesterday, and it expired 15 min after that... Why was your battery at 10% that late in the day? As mentioned, ours were close to full at that time... while we were in a our own little grid outage (no PTO...), had...

    Hurricane season? Tesla Solar is not ready [because owners can not charge from the grid on demand]

    I'm also in the Houston area. We were also outside the Tornado warning area -- it was SW of us... However, our Powerwalls were around 95% when I saw the weather alert. Our reserve is set to 25%, but we utilize the cost savings mode, so the Powerwalls typically charge most of the way up during...

    MP2 or Rhythm or ? [what texas power provider did you choose?]

    FWIW, I received an email from Tesla on Monday asking to confirm if we had selected and MP2 plan or if we were planning on using another provider -- we're in the Houston area. Our install was just about 7 weeks ago (June 23-24) and we have not yet received PTO, although CenterPoint moved it...

    Tesla Inverter over temperature error

    interestingly, I got a proactive call from Tesla the other day saying our replacement inverter was in and if they could install it. I had not called about it - so I’m guessing error alerts or a known bad batch of inverters ID’d the issue. We are out of town, but I went ahead and authorized...

    anyone shade their south-facing inverters from the sun?

    What about using a beach umbrella or sunbrella shade to test? Set it up and take the inverter's temp a few times on a sunny day to see how it compares when in full sun. If it keeps it cooler, you could then figure out the best way to keep it shaded permanently. An awning might work, but a...
