Description
Tesla Powerwall 3 is an integrated 5.8 kW inverter and 13.5 kWh battery system. Capable of partial or whole home backup for cost savings and energy independence when producing and consuming your own solar energy (panels not included), and while staying connected to the utility grid. Manage the system using the Tesla App to customize system behavior to meet energy goals.
Powerwall 3 supports up to 20 kW DC of solar panels, and up to 11.5 kW AC of continuous power with up to an additional 3 expansion battery packs. It has the ability to start heavy loads rated up to 15.4 kW power at 240Vac, meaning a single unit can support the power needs of most homes. Powerwall 3 is designed for fast and efficient installation, modular system expansion, and simple connection to any split-phase 240Vac electrical service.
Requires one of the Tesla Gateway 3, Backup Gateway 2 or Backup Switch to work off-grid as a backup power source. The battery cycle life is not published by Tesla, but the Powerwall-3 comes with a 10-year warranty.

Backup Loads Supported per Powerwall
The largest load in the backup circuit is limited by the quantity of Powerwalls; each Powerwall 3 can support the largest load/breaker size of 60A.
When considering what Powerwall can back up, power is the most important factor to avoid poor customer experience from repeatedly overloading the Powerwall system. Customers are expected to manage their energy usage during an outage, so it is not recommended to factor in energy capacity when determining how many Powerwalls are needed for a system. For that reason, Powerwall 3 Expansion units do not impact the backup loads that can be supported by the system. Adding more Powerwall 3 Expansion units does increase energy capacity and duration during an outage.
Air Conditioning AC Units and Large Motor Loads
- Inrush current (largest instantaneous current draw when a motor starts) is limited to 185 A LRA per Powerwall 3.
- For air conditioner units, use LRA on equipment label as inrush current.
- Other motor loads – Code Letter per 2017 NEC Table 430.7(B), measure inrush via clamp meter identified by manufacturer as capable of measuring < 0.25 second inrush current, or oscilloscope if no code letter or LRA value is listed.
- Design Options if motor LRA is greater than the number of Powerwall 3 units multiplied by 185A: Increase number of Powerwalls or Relocate AC unit/motor load out of backup circuit
- Example: Motor Load unit with 200 A LRA and utilizes a 60A/2P Breaker; Required Powerwall(s): (2) Powerwall 3 units required, so that 200A < 370A; Double-check that the AC breaker follows the Powerwall breaker sizing rules.
