Wall Mounted Batteries

Wall mounted solar batteries are home energy storage systems designed to be secured vertically to a suitable wall rather than placed directly on the floor.

They are commonly installed in garages, utility areas or suitable outdoor locations close to the home’s electrical equipment.

The major advantage of a wall mounted battery is its ability to use vertical space. This helps keep the floor clear and can make battery storage possible in homes where there is not enough room for a large floor-standing cabinet.

Why Wall Mounted Batteries Suit Smaller Homes

Modern homes often need to accommodate furniture, storage, appliances, hot-water equipment and other household essentials. Adding a large floor-mounted battery cabinet can take up valuable space and make already limited areas more difficult to use.

A wall mounted battery makes better use of an otherwise unused section of the wall. It can help preserve walking space, reduce obstruction around vehicles and produce a cleaner-looking installation.

Wall mounting can be particularly helpful for:

• Townhouses with smaller garages
• Homes with narrow side access
• Garages already used for storage
• Properties without a dedicated plant room
• Homeowners who want to keep the installation visually tidy

The final position still needs to meet the battery manufacturer’s requirements and relevant installation standards. A professional installer will assess the property before recommending the most appropriate location.

Powerwall 3 Stands Out as One of the Best Wall Mounted Batteries

Tesla Powerwall 3 is a fully integrated solar and battery system. It combines 13.5 kWh of usable energy storage with a built-in solar inverter, reducing the need for some of the separate equipment associated with more complex battery systems.

For homeowners dealing with limited space, its physical design is just as important as its energy capacity. Powerwall 3 measures approximately 1,105 mm high, 609 mm wide and 193 mm deep. It can be installed using either a floor-mounted or wall mounted configuration and weighs approximately 130 kg.

Its relatively narrow 609 mm body gives installers more flexibility when assessing smaller wall sections. Because the solar inverter is incorporated within the Powerwall 3, the overall system may also require fewer separate components spread across the wall. Tesla describes the integrated design as helping simplify installation and make future system expansion easier.

Make better use of your garage space

The garage is one of the most practical locations for a wall mounted battery because it is generally close to the home’s switchboard and other electrical infrastructure.

Installing Powerwall 3 against a suitable garage wall can help keep the floor clear for vehicles, shelving and everyday storage. Its streamlined appearance also provides a cleaner result than a collection of separate battery and inverter cabinets.

Fits into compact wall areas

Powerwall 3 can also be considered where only a narrower section of wall is available. At approximately 609 mm wide, it may fit into spaces that would be difficult for wider battery cabinets.

This can be useful beside a garage storage area, along a suitable exterior wall or within a designated utility space. Its depth of approximately 193 mm also helps reduce how far the battery projects from the wall.

Indoor or outdoor installation

Powerwall 3 is rated for indoor and outdoor installation. Tesla lists an operating temperature range of -20°C to 50°C, with possible performance derating above 40°C. The battery and power electronics carry an IP67 ingress rating, while the wiring compartment is rated IP55.

This gives homeowners more installation flexibility when garage wall space is unavailable. A suitable outdoor wall may be considered, provided the location meets Tesla’s requirements and all applicable safety and installation standards.

More power in one unit

Powerwall 3 is not only designed to save physical space. Its 13.5 kWh usable capacity can store a meaningful amount of solar energy for evening and overnight use, while its power output can support demanding household appliances when the system is correctly sized and configured.

Expandable storage

Powerwall 3 provides a future expansion pathway for households whose energy requirements increase over time.

A Powerwall 3 system can support additional Powerwall 3 units or up to three Powerwall 3 Expansion units, subject to the approved configuration and site requirements. One Powerwall 3 combined with three Expansion units can provide up to 54 kWh of total usable storage.
