Site Requirements and Pre-Installation Guidance

Ensure Installation Meets All Local Codes and Requirements

Powerwall 3 comes with a Gateway 3 to enable integration with the electrical grid. Powerwall 3 communicates with Gateway 3 by means of a wired connection; wiring and conduit (where required) must be provided by the installer and installed to comply with local codes.

AC isolation and interconnection requirements between Powerwall 3 and the electrical panel are subject to local codes. Ensure that the installation meets local isolation and interconnection requirements. All U.S. and Canada electrical installations must be done in accordance with local codes and the National Electric Code (NEC) ANSI/NFPA 70 or the Canadian Electrical Code CSA C22.1.

  • The connection requirements of the grid operator must be met.
  • The conductors with regards to ampacity, rated temperatures, operating conditions and power loss must be made in accordance with the local standards and the National Electrical Code® ANSI/NFPA 70 or the Canadian Electrical Code® CSA C22.1.
  • The conductor type must be copper wire.
  • The AC and DC electric circuits are isolated from the enclosure. If required by section 250 of the National Electrical Code®, ANSI/NFPA 70, the installer is responsible for grounding the system.
  • The grid voltage must be within the permissible range.
