Choose a Location that Meets Powerwall 3 Clearance Requirements
Powerwall 3 requires adequate clearance for installation, cabling, and airflow. The spacing on either side of units and between units is required to ensure there is sufficient clearance for venting and thermal management features. Do not install anything inside the required clearance above Powerwall 3, or anything that might fall and damage the unit. Do not mount Powerwall 3 horizontally or upside down.
Figure 1. Powerwall 3 Air Intake and Exhaust Vents
CAUTION
In addition to meeting all clearance requirements, ensure Powerwall 3 is installed on a flat surface that is clear of obstructions or protrusions that could damage Powerwall or inhibit airflow. The air vents on the rear and lower front of the unit must remain free from obstructions and accumulation of debris (like foliage or dust).
Figure 2. Powerwall 3 Minimum Mounting Clearances
Minimum lateral wall space 32 inches (808 mm)
Minimum clearance from left side 4 inches (100 mm)
Minimum clearance from right side 4 inches (100 mm)
Minimum clearance above Powerwall 2 inches (50 mm)
Minimum clearance below Powerwall 0.8 inches (20 mm)
Minimum clearance between side-by-side Powerwalls 4 inches (100 mm) *
Minimum clearance in front of Powerwall 12 inches (300 mm)**
Maximum height above ground 45 inches (1140 mm) to bottom of unit feet
Maximum slope +/– 2° side-to-side
*Tesla recommends a minimum of 6 inches (150 mm) between side-by-side units to allow for adequate space for wiring and On/Off switch access.
**This minimum clearance must be maintained at all times, as it ensures adequate airflow for Powerwall 3. A minimum clearance of 36 inches (914 mm) is required in front of Powerwall 3 for sufficient access and working space per NEC 110.26, though that clearance may increase based on local code and/or site conditions.
Note
Powerwall 3 has a fan that produces 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 this noise level when choosing where to install Powerwall 3.
