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.
