It will only start charging at 12:00am as it appears you have a schedule set. It won't charge from any source if it's not at the schedule start time.

Some of the non-bypassable charges are included in the minimum charge (fixed charge). From the proposed decision:

This is what the proposed decision said about the minimum bill.

Yeah, it's annoying. I reported on it last August here.

That's just not acceptable. Do they think your batteries are going to last 7-10 days? I would call back and demand to speak to a supervisor/manager about this! What PW/Gateway do you have?

For this problem, you probably only need a voltage recorder so you can see the change and any spikes or dips. Those are less expensive than a full fledged power line monitor. Some come with a standard wall plug adapter so you don't need to tap into your service panel.

I had a similar problem years ago, right after getting solar in 2006. SCE didn't believe me when I first reported the problem, but after their techs came out and I showed them the data from my Fluke power line monitor they believed it. The street had a 12kV primary distribution and it was...

This is a problem with COS. Easiest way to do it without disabling is to move the left slider up to the charge level you want, and then start charging.

I've never had it start charging before the Powerwall was full. But is often waits after the Powerwall is full to begin, usually until the next 30 minute mark (e.g. on the hour or half-hour) unless I wake up the car before then. And it always stops when my peak period starts, regardless if it...

Try setting a schedule in the vehicle that schedules charging after your peak period ends (e.g. 9pm or whenever it is on your rate plan). This will prevent it from grid charging unless the SOC is below your setting (40%) and it is after 9pm. Then it should be able to start COS once you have...

The car will only report in whole kW (x.0 kW) so the fractional part is lost, and it's rounded down. If you're charging at 3.8kW actual, it will show 3.0kW, and then this affects the house kW display.

See this thread and ask Service to clear the system and reload everything from scratch with latest firmware before replacing the computer. https://teslamotorsclub.com/tmc/posts/8108528/

Happens to me too. Powerwall full, solar generating, and Charge on Solar just stops for no apparent reason with that message. Sometimes it starts up again later (30-60 minutes). Seems to have a lot of bugs.

Doesn't sound right, but Tier 1 support is known for making stuff up. No reason why it shouldn't work with your setup. That said, Charge on Solar isn't very good. You can't prioritize vehicle over battery, it constantly wakes up the vehicle even when excess solar isn't available, it delays...

Sometimes the app doesn't show the Vehicle usage on the Solar graph properly, even though the usage is there (shown as Home instead). I'm using Charge on Solar. Screen captures taken just minutes apart, as it switches from showing Vehicle usage. Do you know why?

Certainly firmware changes could affect how well they respond to grid failures. Since we don't know exactly how they do the detection, or what new shutdown protections they put in the code, this could be a factor. Or the previous grid events were not so severe that the grid load caused a...

While the Powerwall (Gateway really) is capable of detecting grid failures, it does so by monitoring the voltage and frequency upstream of the main contactor which is what's used to disconnect from the grid. Usually this work, but sometimes it does not. By using the Go Off Grid function, you...

Yes, you could remove a panel so the MP1 has an even number (18) and then split them into two parallel strings. You might ask your advisor if the PW 3 supports 3 MPPT strings, in which case you don't have to parallel anything and can stay with 29 panels of three strings (10+10+9). I don't...

The east facing roof MP1 has an odd number of panels (19) and can't be paralleled with itself. Parallel strings need the same number of panels. So they used 10 from MP2 with 10 from MP1, and the remaining 9 on MP1 in its own string. If you could add one more panel to MP1 then it would be two...

Yes, you can extend the antenna. I have 3 Neurios with 15M extension cables and they work fine. You'll need RP SMA connectors and 50 ohm low loss coaxial cable like RG58.

It's called single phase because it comes from a single winding in the transformer. Although there is a center tap for the neutral which splits the single phase into two legs (A & B) it is not "two phase" because both the A and B legs are derived from the same source. It's also commonly called...

Five years, 2 PW outside, TOU from 100% to 20% every day... and still have 13.4kWh capacity in each! Less than 1% degradation.

The vehicle will only output AC because all the connectors (TWC, UMC) are AC only and are connected to the house mains. The purpose and need for the Gateway is to form a micro-grid when the grid is down so the vehicle inverter can sync up to it. And the Gateway will use the Powerwall's...

Without a solar CT, the powerwall won't be able to charge from solar. It is a required component of the system, you should call your installer and have them come back out and put it in for you.

Show us Yesterday.

Here is the full day. Very similar to @yblaser

Here are a couple of links you could look at, but this is probably best done by Tesla technicians. https://service.tesla.com/docs/Public/Energy/Powerwall/Powerwall+-Backup-Switch-Installation-Manual-NA-EN/index.html...

The backup switch is effectively your gateway. It has a contactor in it that can disconnect from the grid. Apparently it failed, maybe due to a power surge or spike, or it just stopped working. Pressing the reset button under the cover closed the contactor, but didn't get it fully working again...

Effect of the eclipse on solar radiation. There was 70% coverage in my area.

It's hard to say if it would have started charging after your peak, but with a storm coming, always best to manually override so you aren't without power. Your install is so new, it will take some time before you know for sure how it works. Once the storm clears, you can turn it back on and see...

Switch to Backup mode now with reserve at 100%. Don't rely on off-peak grid charging or Storm Watch.

If you can relocate those 3 plumbing vents, you could get 4 more panels on the roof.

CTs are spliced in parallel, so the current adds not the voltage. You can do more than two, but you could also run multiple conductors through the CT to get the same effect.

The delay to start at top of the hour still exists, it happened to me again today. Powerwall was full at 1:35pm, vehicle didn't start charging until 2pm exactly. I haven't checked on the hourly wakeup, but that may have been fixed with one of the recent updates. I can say in response to...

I use both, but for different vehicles at the same location. COS still has bugs, and either won't start until the top of the hour, or keeps waking the car up even though the PW isn't full. Charge HQ doesn't have these problems, but doesn't support multiple vehicles (yet). If you use both on the...

This whole episode bespeaks of a larger problem. What if you had arrived at 11:55pm and stayed for 30 minutes? Then only the first 5 minutes should be at the higher rate, and the rest at the lower rate. Or if you arrived at 5:55am (with a rate change a 6:00) and charged until 6:25am. Would the...

No.

Baseline credit is just a reduced rate for usage below the baseline amount. This isn't reflected in the rates, and is deducted (or added) at the end of the billing cycle. If you use electricity then the amount you pay for that portion below the baseline is reduced, giving you a credit at the end...

To find out what the max off-grid frequency shift is, go to: https://<IP Address>/api/site_info and look for: "grid_code_overrides":[{"name":"soc_freq_droop_config_df_max","value":2}] The value shown is the amount over 60Hz. In this example, 2 means 62Hz.

If the grid is up and you see this, it is a problem with the grid. There are a lot of power outages in Maine right now (see here) that are affecting their generation ability. This is what's known as a "Frequency Excursion" and you should report it to your power company. It is likely they are...

Start charging your EV to increase the load, which will drop the SOE % and solar production will stay on. Need to be below about 95% with sufficient load to keep the inverters on. Otherwise, this is normal behavior.

No, PW will not function without the Gateway on and connected.

Was the result less than 11 amps? Meaning output kW was reduced as well as capacity on the degraded units?

Couldn't you turn off the Enable switch on the two good PWs and then see how much the one remaining PW can output in kW?

Yes, you need to delete the "unknown" key.

Another one of the problems with COS. Opening the PW on the App wakes any car with COS enabled. Plus waking the car up every hour anyway when solar is active even before PW is full.

3.45" rain, and no power outages. Lots of humidity though.

This just in from SCE...

A good description from @tmpope is here. The Tesla video of the procedure is here.

Look like there is a new study that addresses this... https://www.cnn.com/2023/08/18/health/covid-vaccine-arm-wellness/index.html
