Tesla Powerwall 3 Specifications and Features
Tesla Powerwall 2 Specs
- 14kWh battery (13.5kWh ‘Usable Capacity’)
- 1150mm long, 755mm wide, 155mm diameter. (45″ x 30″ x 6″)
- 7kW peak power, 5kW continuous power.
- Wall or floor mountable, indoor or outdoor.
- 10 year manufacturer’s warranty
- Scalable (up to 10 AC-coupled Powerwall 2’s)
- Integrated Inverter (converts the DC energy into AC energy you need to use in your house)
- Liquid Cooling
- Control and view your energy usage/storage with the Tesla app (iOS and Android)
- Weighs 119.9kg (264.4 pounds)
- Degradation – it will hold around 70% of the 13.5kWh after 10 years.
- >90% round trip efficiency.
- Wi-Fi, Ethernet, 3G connectivity.
- Off-grid support (AC Coupled)
- Single Phase feed in.
- 100% depth of discharge available.
- Outside of the USA: Powerwall 2 doesn’t include inverter with the DC version and only works with a Solar Edge inverter.
Tesla Powerwall 3 Specs
- Heavily optimised for and integrated with Tesla Solar Roof (Aussies can preorder one now, will be available in 2018)
- Heavily optimised and integrated with Tesla Electric Car (Model S, Model 3 etc.).
- Upgraded intelligent energy management – will learn your household’s usage, draw from weather forecasts etc. to ensure your house, battery, car or hot water stay at 100% and you are only feeding back into the grid when it’s optimal.
- Inbuilt hybrid inverter (i.e. you can plug solar panels directly into it, eliminating the need for a separate inverter for your solar panels. The current inverter is just a battery inverter)
- 28kWh battery (~26kWh usable capacity)
- We predict they’ll stick with lithium-ion for the battery as its price is very affordable.
- Alternatively, Tesla may stick with the 14kWh batteries, make them smaller and easier to install – 14kWh is sufficient power for many households – it depends on the cost/size of the batteries)
- Single and three phase power compatible.
- DC version includes inbuilt inverter.
- By 2018 Tesla expect their Gigafactory to manufacture 35 gigawatt-hours per year of battery cells. Almost as much as the current global combined battery production capacity. What will this mean for the Powerwall III?
- What features do you think the Powerwall 3 will have? What would make it a ‘no-brainer’ for you to purchase? Let us know in the comments.

The cost of the Powerwall 1 and the Powerwall 2 was roughly the same, so we don’t expect the price of the Powerwall 3 to fluctuate more than around 20%.
Powerwall 1 Price (Australian Installation): Around $10,000 (7kWh battery, installation and supporting hardware included).
Powerwall 2 Price (Australian Installation): Around $10,000 (14kWh battery, installation and supporting hardware included).
