Tesla Powerwall 3 in 2024? Release Date, Specifications, Cost.

Tesla Powerwall 3 Release Date, Specs, Cost, and Rumors.

With the great success of the Tesla Powerwall 2, people are already talking about its successor. Although the Powerwall 2 is a fantastic device and can help many households save a lot of money on their power bill, it’s far from a ‘no brainer’ at this point – you need to crunch the numbers to ensure it’s going to be worthwhile to install in your house. But with the cost of lithium-ion dropping rapidly and Tesla competitors chomping at the bit with innovative solutions to battery storage, we’ve no doubt that there’s plenty of work being done on the Tesla Powerwall 3. Could this be the device that finally makes PV solar + storage a standard for homes? Tesla CEO Elon Musk has said that they “expect to sell more Powerwalls than cars” so it’s a major part of their business. What features will the Powerwall 3 have? What will it cost and when can we expect it? Read on for more…

Tesla Powerwall 3 Release Date
Tesla Powerwall 3 – What can we expect?

Tesla Powerwall 3 Release Date

At this point we aren’t sure exactly when the Powerwall 3 is coming out, but let’s look at the time difference between the Powerwall and the Powerwall 2 and see if that gives us any clues:

Powerwall 1: Development commenced in 2012. Announced in 2015 with a pilot demonstration 0f 500 units built and installed. Production moved from Tesla Fremont to Gigafactory 1. Initially came in two models – 10kWh nickel-cobalt-aluminium cathode for backup and 7kWh for daily cycle application. Work on the 10kWh battery was discontinued and they focused on the 7kWh model and brought it to Australia in 2015, with a ten year limited warranty. 

Powerwall 2: Development commencement unknown. Announced in October 2016 at Universal Studios. Production of 2170 cylindrical lithium-ion batteries for the Powerwall 2, Powerpack 2 and Model 3 EVs starts in January, 2017.  First Australian installations early June, 2017. 

Powerwall 3: Potential 2021 announcement? 

October 2020 update: The price of a Powerwall 2 installation in Australia has risen from $11,700 to $12,500.

February 2021 update: Tesla have increased the price of their Powerwall 2…again.  It’s gone up another $800, to $13,300 (13.5kWh system).

Not sure what this means for the 3, but watch this space.

Tesla Powerwalls in 2023

Tesla’s 129MWh South Australian Battery Farm
According to GTM, in Q4 2017 they deployed 143 MWh of energy storage products, which represented a 45 percent from the same quarter YOY (year-on-year). The 129 MWh of energy storage  the Tesla Battery in South Australia partnership last year will be represented in their figures for Q1 2018.

“Solar [megawatts] deployed declined as volumes continue to be impacted by our decision to close certain sales channels earlier this year and to focus on projects with better margins,” Tesla stated. “In addition, solar deployments were affected by the short supply of Powerwalls for customers who wanted solar plus Powerwall in their house. While volumes may continue to be impacted by these factors over the near term, we expect growth to resume later this year.”

So they were about to build the South Australian battery farm within the 100 days they promised, Tesla had Samsung supply the batteries instead of manufacturing them at their Gigafactory. So it looks like they have a way to go with regards to scaling up their manufacturing processes before we start to even think about seeing a Powerwall 3. 

In America, they’ve released new pricing (thanks to CleanTechnica for the stats): 

Effective October 12th, 2018, the new pricing for three energy products is as follows (in USD):

  • Powerwall: $6,700 (originally $5,900)
  • Gateway: $1,100 (originally $700)
  • Installation: $1,000–3,000 (depending on complexity)

“The Tesla Powerwall is a genuinely good option for consumers considering energy storage, and that quality is part of the reason why so many consumers are asking solar installers for it,” Nick Liberati, communication manager for EnergySage, a solar energy system price comparison site operating in over 30 states, tells Inverse. “However, it’s Tesla’s overall brand recognition and luxury appeal that really sets the Powerwall apart from other battery competitors.”

    Tesla Powerwall 3 Specs

    This is all conjecture at this point, but we think some of the features the Tesla Powerwall 3 could include:

    Tesla Powerwall 3 Specifications and Cost
    Tesla Powerwall 3 Specifications and Cost
    • 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 2019 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.

    Tesla Powerwall 3 Price

    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 $12,000 -15,000 (14kWh battery, installation and supporting hardware included).

    March 2019 – Prices for the Powerwall 2 and installation cost have increased between $1,000 – $2,500 due to industry changes. These have been factored into the price above. 

    Powerwall 3 Price: (Australian Installation): We estimate it will cost around $15,000 – $20,000 installed. Call it a hunch.

    Powerwall Installers in Australia

    There are quite a few companies ready to install the Powerwall 2 in Australia – here are some:

    Powerwall Alternatives

    If you’re not necessarily sold on the Powerwall 2 and don’t want to wait for the Powerwall 3, there are many Powerwall competitors and alternatives you can investigate, such as sonnenBYD B-Box Solar BatteryRedback Technologies, Fronius, Mercedes-Benz, and Eaton Nissan xStorage

    Want more alternatives to the Powerwall? Our Solar Battery Comparison area will help – if you have any questions or would like some guidance please email us or simply ask in the questions below! While the Powerwall is certainly an amazing product, depending on your personal circumstances you can get a better result by using one of its competitors. The sonnenBatterie, for example, is onto its 8th iteration and powers 75% of German energy storage – it has a modular capacity from 2-16kWh and, amongst others, is definitely worth a look. 

    2019 Update: sonnen have been bought out by Shell so we expect big things from them in the future. If you’re not in a rush and are interested in future technology like the Powerwall 3, keep an eye on our site and we’ll have updates on what’s going on in the constantly changing world of battery storage.  We’re working hard on a solar battery comparison guide as well and hope to have it to you very soon. 

    Dan Petit on CanadianCor.com has an interesting idea about how he’d like the next gen units to work:

    An entire integrated package rated at 20 kW after 10 years including Gateway, a basic “next-to-garage-breaker-panel” installation cost included, and standard panels (of 5 or 6 kW) as an entire highly competitive total cost should be a very doable thing. A free pack renewal at ten or so years for pre-orders would be the superclincher!!

    Agreed that it would be nice, and doable, but a ‘highly competitive total cost’ doesn’t really scream Tesla, unfortunately. There are better options if budget is your biggest motivator when installing energy storage.

      Tesla Powerwall 2 Australia Release Date, Price, Specs, and Competitors.

      Tesla Powerwall 2 Australia Release Date

      Tesla Powerwall 2 Australia 2018 update: you can get a Powerwall 2 in Australia from a number of different vendors. It depends on which state you’re in – they’re still in hot demand and there are a few states where they’re a bit difficult to come by. If you’re interested in the different energy storage options available to you, please check our solar battery comparison articles (or simply scroll down this article to learn more) – there’s plenty to read up on!

      Also have a look at the case study on Gizmodo of a Melbourne man who says the Powerwall 2 will drop his power bill to $0.

      According to the Tesla website, there is a ‘May 2017’ install date for Australia. Please note that this has changed a few times already and Tesla have moved the goalposts in other ways, such as removing the DC version of the Powerwall 2, so don’t bet the house on it. But we think Q2 2017 will see some Powerwalls in Australian houses! Watch this space and we’ll be reporting as soon as the first Powerwall 2’s start appearing in Australian homes.

      Tesla Powerwall 2 Australia Price

      One 14kWh Powerwall battery is priced at $8,000 AUD. Two will cost you $16,000 AUD, and so on. According to the official Tesla site the ‘supporting hardware’ comes to $750 – and if you buy multiple Powerwalls you will only have to pay this $750 once. Please note this price excludes retailer/distributor connection charges which apply in some parts of Australia (more detailed information about this soon). It also excludes installation, which ranges from $1,150 to $2,900 plus permit fees, as per Tesla’s site.

      Tesla Powerwall 2 Specs

      The Powerwall 2 is substantially upgraded in almost every way from its predecessor, featuring:

      • 1150mm long, 755mm wide, 155mm diameter. (45″ x 30″ x 6″)
      • 14kWh battery (13.5kWh ‘Usable Capacity’)
      • 7kW peak power, 5kW continuous power.
      • Wall or floor mountable, indoor or outdoor.
      • 10 year manufacturer’s warranty
      • Scalable (up to 10 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 125kg (276 pounds)
      • Degradation – it will hold around 70% of the 13.5kWh after 10 years.
      • 90% ’round’ trip efficiency.

      Earlier this year Tesla were taking orders for a DC (i.e. without an included inverter) version of the Powerwall 2 but this has since been discontinued. The only available version of the Powerwall 2 is the AC version with inverter already built. If you’ve already got panels and an inverter it might be worth looking at alternatives to the Powerwall 2. LG Chem produces the RES7H and RESU10H (follow this link to SolarQuotes who have other great information) with 6.6 and 9.3 kilowatt-hours of usable storage respectively.

      Is The Tesla Powerwall Worth It?

      Let’s crunch the numbers. Obviously costs and prices will differ from household to household so plug in your own costs to see if a Tesla Powerwall is right for you. Let’s assume you can store the maximum of 13.5kwh each day, and you’ve changed your power plan to peak/offpeak (read more here). Let’s also assume an installation cost of $10,000 AUD ($8,750 to Tesla and $1,250 to cover installation and connection charges / permit fees).

      The current off-peak price is around 10c/kWh and the peak price 30c/kWh (in comparison to the ‘standard’ everyday price of ~25c/kWh).

      If you were to use all 13.5kWh in peak times, this would save you $2.70 a day, or $985.50 p.a.  (30c – 10c = 20c) (20 c x 13.5) (2.70 x 365).

      By the 10th year, assuming the stated 30% degradation, you would have 9.45kWh which represents a saving of $1.89 a day, or $689.85 p.a.

      You can use NREL’s PVWatts calculator to find out exactly how much sun you can expect at your residence. It’s a bit complicated but an amazing tool for those who want to get granular about the postential for solar savings.

      Tesla Powerwall 2 Australia is only useful for some people at this point in time – solar panel and energy storage technology is coming along in leaps and bounds so this will only get more economical. There are also other options that may suit your individual circumstances.

      Tesla Powerwall Competitors and Alternatives

      There are a number of Tesla Powerwall alternatives – some would argue that you’re paying for the ‘prestige’ of the name. Always do your research before you buy something based on advertising or what your friends say – solar and solar storage come down to your individual requirements. It’s definitely worthwhile to carefully measure the numbers before you commit to anything!

      And without further ado, have a look at some of your other choices – they may not be as sleek, but utilitarian can be sexy too:
