Just a question for those in the know. Im looking at setting up a complete off grid system with 2x powerwall 2's. With the powerwall in full backup mode does it ever try to export to the grid?
Reason I ask, i'm looking at purchasing a pure sine wave inverter generator to act as the typical grid input as a backup for times in need.
2nd what charge rate will the powerwall's charge from the grid? eg if the house is using 1kw will it consume 4kw from the grid to speed the charge?
