Required Supplies
- Mounting bracket hardware (see Appendix A: Powerwall+ Mounting Details)
- Wiring methods (depending on
local electrical requirements)
- For installations where communication wiring must be protected, ½ inch LFNC Liquid Tight Flexible Non-metallic Conduit (LFNC) with NPT threaded fittings
- For installation where communication wiring protection is not required, ½ inch NPT threaded cable glands
- Minimum 600 V rated 4-conductor
(twisted pair optional) or double-insulated (with one twisted pair) shielded
cable (for communication connection between Powerwall and the Backup Switch)NoteIf custom cable is used, it must meet the following specifications:
- 16 AWG or 18 AWG (according to wiring distance limits defined in Plan Distance Between Components)
- 4-conductor (twisted pair optional)
- Class 1 Circuit Listed
- Outdoor-rated
- Overall shield with drain
- Minimum 10 AWG, 600 V rated, UV
resistant, 90°C rated, copper (Cu) wire
- DC and AC wiring conductors must be made of solid wire, stranded wire or fine stranded wire. When using fine stranded wire, bootlace ferrules must be used.
- Conductor cross-section intake range: 10 AWG to 6 AWG (6 mm² to 16 mm²)
- Oxide-inhibiting electrical joint compound
Optional Supplies
- Luggage lock (such as a Master Lock 120 series) for securing the solar assembly door shut
