Tesla releases more details on Powerwall 3, confirms cheaper stack coming
Tesla has released more details about Powerwall 3, its new generation home energy storage system, and there’s some more good...

This is awful or great timing for me depending on how you look at it. I was just about to sign paperwork for a 23.49kW Panel system with 2x PW+ and 2x PW2 + 5.7kW inverter added to get to 20.9kW AC output. They told me they cannot use PW3 even if I wanted to downgrade to 2 because my utility considers all possible inverter AC output in their max number and their limit is 21. This is true even if the inverters are derated/disabled:
"Hi Michael, this is ..... with Tesla. That is correct. Due to the utility restriction, all the Powerwalls will be the Powerwall 2, and two of the four will be the Powerwall 2+ (includes an inverter). Our Design and Engineering Team did confirm that this will offer a whole home backup solution, meaning that all of your electrical appliances can be supported. If we were to change your project to include just two Powerwalls, the Powerwall 3 would still not be eligible because it would still surpass the utility AC limit."
I asked about whether there would be a discount since I would be technically receiving older hardware. His answer:
"Regarding the pricing, it is the same for the Powerwall 2 and Powerwall 3."
After this texting earlier, I saw the article above and asked him if there was a way to make it work with the PW3 DC Expansion. No answer yet. I'm thinking it might make most sense for me to stall or eventually cancel the process and likely lose my $100 deposit for now and then pick it back up once the DC Expansion versions are approved. However, I have a feeling I am going to be told that still, PW3 won't work for me due to the size of my solar system and the needs of inverters.
