A Powerwall is a slim and compact unit. It can be floor-mounted or wall mounted, in a cool, dry, and ventilated area, away from direct sunlight and heat sources (this can be both inside the home or outside).

The location should also provide easy access for maintenance and be near the home's electrical panel for efficient wiring. Installation requires the engineer to wire the unit to the property's electricity system and solar panels and install an integrated inverter*, and typically takes a few hours.

*A device that combines the functions of an inverter and a battery charger into a single unit for greater efficiency.
