Close the Wiring Compartments and Turn the System On

Before closing any installed hardware, take photos of the completed wiring in the Powerwall, Backup Gateway, and main distribution board.

Ensure that all conduit junctions and cable entry points are secure and properly sealed.

Arrange the communication and AC power wires neatly inside the Powerwall wiring compartment.

Replace the cover on the Powerwall wiring compartment. Ensure that the cover seats properly on the gasket so that the compartment is sealed. Using a Torx T20 bit, tighten the fasteners to 1.5 Nm.

Replace the left side cover on Powerwall by pushing the top into place and working toward the bottom to reattach it to the clips along the length of the unit.

Install the Backup Gateway dead front panel and secure it firmly with the original screw. Mount the Backup Gateway door, and latch it shut.

Use the provided breaker label sheet to clearly label the circuit breakers.

Note

If the Backup Gateway is installed outdoors or in a high-traffic area, the latch can be locked shut.

Switch on the AC circuit breakers for the Backup Gateway and Powerwall.

Warning

Upon powering on the Backup Gateway and Powerwall system, allow it to boot up undisturbed for at least one minute. Do not power cycle or reset the Backup Gateway during this time, as the boot sequence must be completed for the software to operate properly.

Switch on Powerwall by moving the switch on the right side of the unit to the ON position. When Powerwall establishes communication with the Backup Gateway, the LED on the right side of Powerwall illuminates.

Note

The Powerwall On / Off switch has a locking mechanism. When the switch is locked it cannot be turned on.

CAUTION

Always leave site with Powerwall breaker closed for battery to maintain a base level of charge. Leaving the Powerwall disconnected from AC for extended periods increases risk of damage.
