Note
There is no wind speed limitation on Powerwall and anchoring equipment when mounting in interior locations.
The following conditions will require additional site-specific evaluation by the installing company's structural engineering team:
  • Wind Exposure Category D
  • Wind speeds greater than 180 mph
  • Poured concrete pad and steel post construction in regions with seismic above SS = 2.37
  • If needed, reference the linked third party resource for Seismic Categories, Wind Speeds and Exposure Categories: https://asce7hazardtool.online/
