Plan Distance Between Components

Follow the table below for maximum distances between system components. Wire gauge must meet local codes and in some circumstances wire gauge requirements change based on distance. Refer to Appendix B for wire gauge requirements.

Distance to Measure Maximum Cable Length
Backup Switch to Powerwall+*

150 ft (45 m) for 16 AWG (1.5 mm2) wire
82 ft (25 m) for 18 AWG (0.8 mm2) wire
Powerwall+ to Internet router (wired Ethernet connection) 328 ft (100 m)

*Total length of communications cable, including daisy-chained connections, through last Powerwall in chain

Note
As noted in Required Supplies, minimum 600 V rated 4-conductor (twisted pair optional) or double-insulated (with one twisted pair) shielded cable is required for the communication connection between Powerwall and the Backup Switch; see Required Supplies for custom cable requirements.

CAUTION
Failure to follow minimum cable size and length requirements may result in intermittent or unreliable operation of the Powerwall+ system. In systems that do not meet these minimum requirements, performance issues may arise even after successful device setup.
