Discussion: Powerwall 3 [Speculation / Discussion etc]

100A. They're relocating everything to a new 225A subpanel that's downstream of a Backup Gateway.
EDIT: The diagram shows a 50A breaker inside the Backup Gateway feeding the PW3. I suppose that's cutting it close if the PW3 is capable of outputting a sustained 11kW. 100A is the main breaker at the meter. That's not changing.

Andy,
Is the pricing higher than PW2?
My site inspection was last week and updated quote is just under $25k for two PW2s, including installation.
If price is in that vicinity for PW3, I may request a change order. I think permit application was already submitted but ….

The one below it is the Powerwall+ so I think it just means it has a built-in inverter so you can attach solar to the unit directly.
I agree; that would make the higher maximum output a combination of the battery and the solar inverter.
The branch circuit for the Powerwall 3 is 100A or the subfeed?
With the approx 11 kW inverter of the PW3 I assumed a 60A breaker would be used for the branch circuit.
Sorry, I was confused by the original question.
The main breaker to the house is 100A and that's not changing.
The line diagram shows a 50A breaker inside the Backup Gateway which connects to the PW3. So yes, I agree that a 60A breaker seems like it'd be a better choice given the PW3's higher output. Hopefully this won't be a big deal; I can't picture many scenarios where the load on the PW3 would be that high, frankly.
Strange that the breaker is still 50A for that large of an inverter. Perhaps this is only to help startup large loads and the continuous output stays the same? I would otherwise expect a 60A breaker. Certainly it will have the breaker that it was designed for.
Had my site assessment done today. Powerwall 3 training is next week. No capacity change known, only input/out capabilities with DC linkage between units and solar. Basically what they originally wanted to do with the Powerwall+ unit as an all in one package. 20kWh in/out, again what I was told. Will update here again when I have my site plan done.
I think I get it. Solar can produce up to 20kwh, inverter can supply up to 20kwh with solar+battery
Bumping up from previous Powerwall + specs of continuous power. I believe it was 9.6/10 without looking.

That would require a 100A breaker. The current Powerwall+ requires a 50A breaker since its max continuous output is 9.6kW (40A).
That's seems right!
I talked with crew today, they said that they have training now for PW3. and inverter is inbuilt, dimension of PW also reduced.
