I think you meant $0.2/kWh😃. The Tesla webpage linked above says there is at least one event per month.

Not to add on to the feature creep but a couple things that would be useful to me: Immediate manual control of the mode and reserve level. I would probably never have to open the Tesla Energy app if Netzero could do this. One time automations. For example, if I know there is a storm coming...

Nice job integrating the vehicle usage and home usage into the same graph on the home page. I was going to request something along those lines, but you did it better than what I was imagining.

I haven't played with COS since it initially rolled out, but at the time if you logged out of the app and back in COS would show up again.

Even with no clouds the amount of PM in the atmosphere will change how much of the light is scattered. It might be an artifact of the camera's autogain, but the last day looks like there might be more scatter as the sun looks "bigger." A breeze will also change the temperature of your panels...

I guess I've never been too concerned that my phone would stop working or at least I could figure out how to get it working again. The only thing I can think of is to turn off the powerwalls or reset the system which should bring it back on grid. I am only familiar with PW2s, so I don't know...

The eclipse bar seems to be about an hour off for my area. It shows approximately 11:30-1:30 whereas it should be ~10:30-12:30 in Los Angeles.

Using the Go Off-Grid function physically opens the contactor in the gateway (or backup switch) to separate your system from the electrical utility. If you have non-backed up loads they will be still powered from the grid. In off grid mode if there is an issue supplying your home load it will...

One thing I noticed is the total grid import/export seems to be off in comparison to what the Tesla app says, although the net usage is the same. For example, earlier this week I didn't draw any power from the grid (i.e. running self powered and never reached the PW reserve). The Tesla app...

As part of a job to install a whole house HP earlier this year I asked the contractor to quote installing a 12k BTU mini split in our second floor master bedroom. Quote was $6k and included a fairly long and complicated electrical run since the compressor would have been on the opposite corner...

It depends. With MDCs involved it is cheaper to pull from the grid up until you reach your MDC (on average). Once you reach your MDC pulling from the PW is cheaper ignoring sunk costs into the PW and any negative effects on the PW longevity. Without MDCs or once you have exceeded your MDC...

Thanks. After I posted I went back in this thread and also looked at my Tesla data to get the dates. I think there was also an event on 7/26/23. Having the times as well is helpful. If I ever get time, it will be interesting to pull the PW data to compare it to the compensation I got.

That kind of annoys me too. You could try @offandonagain 's NetZero app automations to use TBC during the day and automatically switch to self-consumption at the start of peak. On cloudy days using TBC during the day would prevent you from using the PW before peak and prioritize getting enough...

The compensation is based on PW discharge relative to the baseline PW discharge according to the program rules. Most of my discharge went to my AC during the event days and I was compensated at $121 per PW (discharged 100% to 10%). Because most event days are generally the only really hot...

It's been a few years since I went through the process, but I think the OP is not talking about estimated production. I believe when you initially start the process and pick a system size they estimate the effect on your energy bill to help guide you on what size system to get. This is before...

At first glance it looks normal to me. From your handwritten diagram it looks like String 1 is wired to the inverter input 1 and String 2A and 2B are paralleled into inverter inputs 3 and 4. Inverter input 2 would then be unused and it would be normal to see that message.

We're just at 5" for this storm with over 9" this month. The Feb 1st storm was worse with respect to intensity as we got 4" in 5 hours with rates hitting 2"/hr. Lots of significant street flooding with that one. I haven't used storm watch as our electricity has been pretty reliable in our...

According to the spec sheet the PW3 has 6 MPPT inputs, so the best solution would be not to parallel any of the strings, but for some reason Tesla likes to design systems this way. BTW having two strings in parallel is inefficient if there is non uniform shading between the two strings...

Thanks. I assumed the conversion from HSPF to COP yielded an average COP over the season given some assumed climate and didn't realize it would yield a COP at a specific temperature. That helps.

I am getting a heat pump installed next week in coastal Southern California and have been trying to do the fuel cost comparison relative to my old 80% efficiency natural gas furnace. It seems close to break even with gas at $1.50/therm, although last year at this time it was $3-4/therm, and off...

Not an expert but my understanding is that the number of MCIs required is primarily a result of a safety requirement to keep the max voltage on the roof below a certain value when the system is shutdown. Decreasing the number of MCIs would increase the voltage on the roof when shutdown and...

No need for insults. We are a better forum than that. Fair enough. My comment was in relation to reliability/redundancy. I didn't appreciate panel level monitoring was your number one priority.

Care to expand on that? I'm all for being wrong and learning something.

Aren't optimizers the worst of both worlds? You have optimizers on each panel plus a central DC to AC inverter.

Click continue on the first screen. On the next screen (same as the pic in the first post of this thread) with the link to download Tesla Pros click "Upgrade Later" at the very bottom of the screen to get back to the old Tesla login. Credit goes to other form members for discovering this.

If your provider is LADWP then you may not have any NBCs. LADWP as a publicly owned energy provider is not covered under the CPUC net metering rules.

As @offandonagain pointed out they have wired 1A and 1B in parallel. While likely not a huge impact when you consider your total yearly production it is not ideal. For example in your Aug 21st at 9:30am photo, 1B has about 2 panels shaded. While this is happening you will lose an equivalent...

Interesting... Is it vented from the back? If so, does the plastic scoop on the top have fans to pull the air over the fins?

From other posts it sounds like the Powerwall severly limits or stops charging altogether as the temperatuer goes below freezing. I would imagine discharge rates would similarly be impacted. See this thread for example...

The annual payout is based on your total usage regardless of TOU category. If you are a net consumer you don't get a payout on the annual bill. If your net energy charge (under "tracked charges" on your bill) is positive then you will owe that amount at the end of the year. If it is negative...

In this case though isn't the "main breaker" that the OP is talking about just really a locked down branch breaker used to back-feed into the subpanel? If the breaker is getting warm to the touch I would also make sure that the appropriate length of stripped wire was inserted into the breaker...

The current transformer only measures current and needs a separate voltage tap. That is why it is important that your CT and voltage tap are measuring the same leg of the split phase. For example see this link specific to setting up the Neurio...

It's @offandonagain 's Netzero app. The dots are estimated production from PVWatts.

This is what my generation looked like also in SoCal with no clouds: Here's a pic I captured at the peak of obscuration with my phone:

I would ask your installer to have the panel supplier provide a lien release/waiver prior to paying your installer in full.

To date there is no way to access the standalone Tesla inverter besides power cycling it and connecting to the wireless access point it broadcasts. Unfortunately you can only do this for the first 15 minutes after the power cycle. There is no known direct web or API access to the inverter...

That sucks. 866-701-7868 is the number on SCE's website for NEM customers. I would start there in addition to working with your installer.

The "Solar Billing Plan" is SCE's NEM 3.0 implementation. https://www.sce.com/residential/generating-your-own-power/solar-billing-plan Since earlier in the email they confirmed that you remain on NEM 2.0 I would guess this might just be a form letter error and they reference this on all their...

Wow, that's a strange choice on Tesla's part especially considering that their documentation directs you to the web interface to monitor the status of the system in the event of a power outage with no internet access. Glad the api endpoints still work.

Semantics, but the solar production will never exceed the inverter maximum. The inverter regulates the solar production by choosing where it operates on the V-I curve of the panels. Normally the inverter tries to optimize the V-I to reach the maximum power point (MPP) for a particular string...

There is a high likelihood that the system will not switch seamlessly in the event of the power outage. You can expect anywhere from an instantaneous switch to 10s of seconds depending on the state of the system and the nature of the interruption. I wouldn't rely on it to protect anything...

Here is a megathread with people posting their layouts, although it has been a couple of years since last posted to. https://teslamotorsclub.com/tmc/threads/post-your-tesla-solar-layout.197392/ Seems like most are landscape. Early in the thread I see that some have mixed landscape/portrait...

It seems Tesla certainly prefers the landscape orientation based on all the designs I have seen posted here. On my system there was one roof plane that was supposed to have six panels in the landscape orientation, but on install day the installers realized they wouldn't fit as designed. They...

New one scheduled for tomorrow for 6pm-9pm. Not that it matters for compensation but it should be a little cooler here so we don't have to use AC. For a few minutes during tonight's event we were actually pulling a small amount from the grid with the AC running and the new algorithm to end the...

Would a non-Tesla inverter work with the Tesla installed MCIs? From their service page: The Tesla MCIs are normally open solid-state switches (no moving parts). Powerwall+ has a built-in exciter circuit that activates (closes) all MCIs via a 250 kHz AC frequency signal when the inverter is...

Thanks. I deleted the key CoS setup in the car and logged out and back into the app. The app is now asking me to setup CoS again, but loading the app to the Energy screen still wakes up the car. I guess all the more reason to use your web app:)

My system isn't charging now. I'm at 8% and raised my reserve to 30%. The app does show the event for tomorrow. Edit: Hopefully it doesn't start charging while I'm asleep. Do you have grid charging enabled?

Event started but the discharge behavior seems a bit different then normal. Normally the PW would discharge at a rate to bring me to my export limit (~7.4kW), but right now they are bouncing between 5.5 kW and 6.4 kW with my solar pretty much covering the house load.

Thanks. I have COS disabled and haven't used it because of all the issues that have been posted here. I assume I have to go further and delete the key generated during the pairing to stop this from happening or is this now a feature of the app?

I just noticed this today, and I don't think this is how it used to behave. If I open the app directly to the Tesla Energy screen (i.e. I was on the Tesla Energy screen the last time I used the app), it appears to wake the car. Previously I thought it would only wake the car if a swipe over to...
