Wiring Instructions
Wiring with a Tesla Powerwall 2
Instructions for connecting the Tesla Powerwall 2 to the system.
Wiring with a Tesla Powerwall 3
Note:
Tesla Powerwall 3 requires a Backup Switch or Gateway 2 for installation.
Wiring with a Tesla Powerwall+
Note:
Tesla Powerwall+ also requires a Backup Switch or Gateway 2 for installation.
Enable Low Voltage Relay for Tesla
Note:
This step is only necessary when using Tesla Gateway 2.
Finding the Tesla IP Address
- Navigate to the menu option and select Devices on Network.
- Find the IP Address of the Tesla system and record it.
- Select Power Sources in the main menu to proceed.
Add a Power Source
- Choose Battery Storage under Power Sources and select the appropriate Tesla Powerwall model.
- If using GPIO wiring for Grid Detection, set the GPIO for Grid State setting to GPIO 1.
- Enter the recorded IP Address as the Inverter IP Address.
- Enter the maximum Continuous Inverter Output (kW) of the Battery Inverter.
- Important: Only enable Whole Home Backup if the Battery Inverter can support the full capacity of backed-up loads while Off-Grid.
Wiring
Wiring with a Tesla Powerwall 2
The Savant Power Director and Tesla Powerwall 2 are connected via Ethernet cable or Wi-Fi and must be on the same network. Savant recommends running a single pair of black and red wire size #18-16 AWG from auxiliary pins 3 and 4 on the Tesla Gateway to the GPIO 1 connection port of the Director. The GPIO is used to monitor the Grid State and is recommended when using an off-grid load-shedding relay. The detection of grid changes by thedirectorr is faster than the Ethernet connection when using the GPIO. However, GPIO connections are not required for the Director to function. See the diagram below.
Wiring with a Tesla Powerwall 3
The Savant Power Director and Tesla Powerwall 3 are connected via Ethernet cable or Wi-Fi and must be on the same network. If the installation includes a Tesla Gateway 2 run a single pair of black and red wire size #18-16 AWG from the auxiliary pins 3 and 4 on the Gateway to the GPIO 1 connection port of the Director. The GPIO is used to monitor the Grid State and is recommended when using an off-grid load-shedding relay. The detection of grid changes by the Director is faster than the Ethernet connection when using the GPIO. However, GPIO connections are not required for the Director to function. See the diagram below.
NOTE:
The Tesla Powerwall 3 requires a Backup Switch or Gateway 2. If the installation is using the Backup Switch the GPIO wiring is not used.
As of the release of this document; the Tesla Powerwall 3 does not support GPIO connection to the Tesla Gateway 2. This is planned for a future release by Tesla.
Wiring with a Tesla Powerwall+
The Savant Power Director and Tesla Powerwall+ are connected via Ethernet cable or Wi-Fi and must be on the same network. If the installation includes a Gateway 2, Savant recommends running a single pair of black and red wire size #18-16 AWG from the auxiliary pins 3 and 4 on the Gateway to the GPIO 1 connection port of the Director. The GPIO is used to monitor the Grid State and is recommended when using an off-grid load-shedding relay. The detection of grid changes by the Director is faster than the Ethernet connection when using the GPIO. However, GPIO connections are not required for the Director to function. See the diagram below.
NOTE:
The Tesla Powerwall+ requires a Backup Switch or Gateway 2. If the installation is using the Backup Switch the GPIO wiring is not used.
Enable Low Voltage Relay for Tesla
During the commissioning of the Tesla Gateway, ensure that the Low Voltage Relay Control (LVRC) is enabled if the GPIO wiring was installed with the Gateway 2. This feature can be enabled in the Advanced Settings section of the Tesla One app. A login is required to access the Tesla One app settings. Enabling the LVRC is a critical step to facilitate communication between Tesla and Savant. This will enable the GPIO communication between the Tesla Gateway and the Savant Director that was established in Step 1.
NOTE:
This step is not required if using the Backup Switch and is only available when using Tesla Gateway 2.
Finding the Tesla IP Address
The Tesla IP Address is needed to enable communication between Tesla and Savant.
- Navigate to the menu option at the top right of the screen, then select Devices on Network.
- Here is the IP Address of the Tesla system. Record the IP Address for the next step.
- Select Power Sources in the main menu to move forward.
Add a Power Source
- In the Power Sources option, choose Battery Storage. Then, select the appropriate Tesla Powerwall that matches the hardware being integrated, from the available options. (Tesla Powerwall 2, Powerwall 3, or Powerwall+)
- Enter the Tesla Account Email Address and Tesla Account Password.
- The Tesla Account Email Address can be either the Installer or Customer Email Address.
- For Powerwall 2 and Powerwall +, use the Tesla Account Email Password to log in.
- For Powerwall 3, the Tesla Account Password is the last 5 digits of the Network Password printed on a sticker attached to the Powerwall.
- If the GPIO wiring for Grid Detection is used, set the GPIO for Grid State setting to GPIO 1, otherwise leave the setting blank.
- Enter the IP Address recorded in section 3 step 2 for the Inverter IP Address.
- Enter the maximum Continuous Inverter Output (kW) of the Battery Inverter.
IMPORTANT!
Only enable Whole Home Backup if the Battery Inverter can support the full capacity of backed-up loads while Off-Grid.

IMPORTANT NOTE!:
The Tesla Account must be the Customer Account used to log in to the Tesla Gateway. This account can differ from the credentials used for the Tesla One app. Follow the Tesla Documentation to log in to the Gateway with a Customer Account and verify credentials are correct.
