Ok, well that's annoying, but probably understandable that the video is now private.
Here are some of the things that I remember, keeping in mind this was installer focused.
1. A single Powerwall 3 can charge a Model 3 at the highest AC rate, due to the maximum continuous output of 11.5 kW.
2. They compared installing a Powerwall 3 to earlier models, including a time lapse video and it was hours for the older models (with more boxes on the wall) vs < 1 hour for the new model (integrated solution).
3. You can put 3 Powerwall 3's together (40.5 kWh) and then use DC Expansion (see Q3 above) to add more, with up to 12 (4 x 3) supported (I think).
4. The flexibility of both DC and AC coupling is going to be great for new or existing systems.
5. The built-in inverter has support for 6 solar panel strings to allow for different roof shapes and shading issues. The maximum solar panel capacity is 20 kW.
6. They showed a video of a Powerwall operating in a couple of feet of water, saying that they are laser welded and designed to keep operating during flooding.
7. By integrating the controller (gateway), inverter and having direct DC connections they have removed complexity for installation and improved efficiency.
8. There was a lot of information on how they designed the internals for easy installation, e.g. space for hands to connect wires, etc. Then the packaging and things like ramps and trolleys that are designed specifically for the Powerwall to make it easier while protecting the product.
If anyone else managed to watch it, please share what you remember.
This was a USA launch, so there was no information about other countries
