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 Switch to Powerwall+ unit(s)* |
150 ft (45 m) for 16 AWG (1.5 mm2) wire |
| Neurio Energy Meter to Powerwall+ (RS485 wired connection) | 164 ft (50 m) |
| 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.
Maximum Neurio CT Extension
| Neurio 200 A CTs (Remote Metering) | Maximum Extension Length |
|---|---|
| Using Neurio CT extension harness (Tesla P/N 1622289-xx-y) | Up to 15 ft (4.5 m) |
