Using the Tesla website calculator and my own SECO bills it would take between 3 and 4 PowerWall batteries to power my designer house for 1 day. The cost would be between $17,000 and $23,000.
The 7 day estimate is only valid for a house that also has solar power installed and assumes that system can, on average, generate enough energy to provide a days worth of electricity.
