3. Site Requirements

Powerwall Physical Requirements

Powerwall can be mounted on a floor or wall. When floor-mounted, it must also be anchored to an adjacent wall. In both types of installation, the wall must be capable of supporting the full weight of Powerwall and its mounting hardware. The wall must extend to all edges of the system, allowing no access to the back of the unit once it is mounted.

Powerwall includes a mounting bracket (Fig. 1) that supports the unit in both floor- and wallmount configurations, and includes shims to level the unit in floor-mount configurations. Do not use other hardware to anchor Powerwall to the wall or floor.

Figure 1: Powerwall 2 Mounting Bracket Dimensions

Powerwall requires adequate clearance for installation, cabling, and airflow. Do not mount any other objects within the clearance space (Fig. 2), except those explicitly required by the installation (for example, conduit, a junction box, or an electrical disconnect, depending on local installation codes). Do not install anything above Powerwall that limits access to the unit or that might fall and damage the unit. Do not mount Powerwall horizontally or upside down.

NOTE: Powerwall has a pump and fan that enable Powerwall to maintain ideal battery temperature. They produce a gentle hum during operation, comparable to a typical refrigerator. The noise level depends on the ambient temperature and the power level of operation. Consider these noise levels when choosing where to install Powerwall.

Powerwall Dimensions and Space Requirements

Figure 2: Powerwall 2 Dimensions and Space Requirements

Powerwall Temperature Requirements

Powerwall is capable of charging and discharging within the full ambient temperature range listed in the Specifications section. At the high and low ends of the temperature range, Powerwall may limit charge or discharge power based on battery cell temperature to improve battery lifespan.

Installation in full sun raises the temperature inside the enclosure above ambient temperature. This temperature rise is not a safety risk, but may impact battery performance. To optimize performance, avoid installing Powerwall in locations that are exposed to the sun for extended periods.

Do not install Powerwall in locations with sustained high or low temperatures. The average ambient temperature over the system's life should be between 0°C and 30°C (32°F and 86°F).

10 Powerwall Installation Manual

Step 1. Plan the Installation Site

Maximum

Cable Length

The installation location for Powerwall must accommodate placement of the Backup Gateway and meet all conditions described above in “Site Requirements.” In addition, consider the following points when choosing where to install Powerwall.

Wall mounting: Choose a wall capable of supporting the full weight of Powerwall, with one of the following characteristics: wood studs at regular intervals, plywood sheeting of sufficient thickness, solid concrete or masonry, or metal studs of sufficient gauge.

Floor mounting: Choose a level surface adjacent to a wall space that meets all the requirements for wall mounting described above. Make sure the area is isolated from hazards that may damage the unit, such as vehicle traffic or flooding.

Cable entry: Determine whether cables will be routed into Powerwall from the side or from the back of the unit. With side cable entry, a conduit fitting or cable gland must be used to seal the entry into the wiring compartment. With back cable entry, a wire cover should be used to seal the entry into the wiring compartment.

NOTE: If you mount Powerwall on a wall with studs spaced 24 in (610 mm) apart, cable entry from the back of Powerwall may be blocked.

Backup Gateway configuration: Determine whether cable entry into the Backup Gateway will be from the top, bottom, or side. When cable entry is from the bottom half of the enclosure, the back panel of the unit must be removed and rotated 180 degrees.

NOTE: For cable entry at the top of the Backup Gateway enclosure, an HS-style hub should be used in order to maintain enclosure ingress protection.

Electrical service connection: The Backup Gateway is service-entrance rated, and can be located between the service entry and the main electrical panel. If overcurrent protection is required, a circuit breaker can be added to the Backup Gateway at the service entry. The Backup Gateway can accommodate two different circuit breaker sizes: 100/125A, and 150/200A.

Cable gauge and length: Powerwall requires cable connections to the Backup Gateway, electrical service panel(s), and an Internet router. Position Powerwall, the Backup Gateway, and other electrical components to minimize cable lengths, based on local code requirements.

Cable Type Connection Cable Gauge

Power Powerwall to electrical panel 5-8 mm2 (10-8 AWG) 45 m (150 ft)

Power Backup Gateway to electrical panel 16–120 mm2 (6 AWG-250 kcmil) [Local Code]

Communication Powerwall to Backup Gateway

2 twisted pairs, 1.5 mm

Communication Backup Gateway to wireless router CAT5 45 m (150 ft)

(24-16 AWG)

- or -

CAT5

50 m (165 ft)

15 m (50 ft)

Conduit or raceway: Calculate the amount and size of conduit or raceway needed for the installation, based on fill limits and local code requirements. If you are using conduit, an adapter may be required between the entry into the Powerwall wiring compartment and the conduit.

Step 2. Transport and Unpack Powerwall

NOTE: Powerwall is heavy. Wear appropriate personal protective equipment (such as gloves and protective footwear) when handling the unit. Only a sufficient number of trained movers should lift Powerwall. Use of lift equipment is recommended. For more information, refer to
