Informative thread, thank you. We have a Powerwall, solar and an Atto.
Is there a way the battery solar system can be wired so the atto can charge the Powerwall during a grid outage? The idea being the Atto pushes a topping up charge of 2000w into the battery simultaneously as the battery can provide up to 7kw to the home. Conceptually the Powerwall can deliver more amps than the Atto and the PW is already configured to run the backup circuits… Would seem to be an elegant solution if it’s not defying the laws of physics:)?
