OK. So I got my line diagram in today. Should this be sufficient in backing up 1 200a panel and being able to see both 200a panels and use while on the grid? The installer told me it would, but just wanting to get a second opinion. Basically, I want to be able to see all loads on the app, and be able to use the powerwall to power everything in my house while on the grid. I understand that off grid I will be limited to 1 200a backup panel.
