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: Wiring Reference for wire gauge requirements.
| Distance to Measure | Maximum Cable Length |
|---|---|
| Backup Gateway to Powerwall unit(s)* |
150 ft (45 m) for 16 AWG (1.5 mm2) wire |
| Neurio Energy Meter to Backup Gateway (RS485 wired connection) | 164 ft (50 m) |
| Backup Gateway 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 copper (Cu) cable is required for the communication connection between
Powerwall and the Backup
Gateway; 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.
