Tesla Powerwall 3 in 2019: 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

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 2019 announcement.

Tesla Powerwalls in 2019

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.”

  • 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

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

  • 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.

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 $10,000 (14kWh battery, installation and supporting hardware included).

Powerwall 3 Price: (Australian Installation): We estimate it will stay around $10,000 installed. 

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. 

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.

Camberwell Grammar School Solar System

The 862kW Camberwell Grammar School Solar System has been installed in Canterbury and all 2,607 solar panels are currently generating electricity for the largest solar project on any school in Australia. IT will generate 1GWh (1 million kWh’s) of clean energy every year. 

Camberwell Grammar School Solar System - Gippsland Solar

The Camberwell Grammar School Solar System

The team at Gippsland Solar (comprising of 14 commercial installers who were put up in Melbourne for the duration of the project) set up the school solar system, which includes two ‘off-grid classrooms’, earlier this year. It’s been a technically challenging process that required 3D drone modelling, complicated electrical and structural engineering. The first 550kW was delivered over the Christmas school holidays and the remaining 312kW was completed at the end of term one, so as to minimise the amount of disruption to students.

According to the Gippsland Solar Facebook page, the system will generate just over half of the school’s usage and during the holidays they’ll export any excess power back to the grid.

System Details – Gippsland Solar

  • Solar panels – 2650 x Trina 350W frameless panels
  • Inverters – 34 x Fronius European inverters
  • System capacity – 862kW
  • Power production – Approx 1,000,000 kWh’s per year
  • Carbon savings – Approx 1,200 Tonnes per year
  • The school is now looking into installing a Tesla Powerpack battery to go with the solar system. 

Another huge step forwards for commercial solar as we see projects like this become financially feasible. What’s also great to note is that the project was entirely driven by the school student council, who presented the idea to the Camberwell board.

Solar Battery growth rises in 2017.

Solar battery growth continues to rise exponentially – the huge rises in the price of electricity over the past 36 months have led to a record uptake in the number of Australian households opting to install solar batteries for energy storage. Although still in its relative infancy, the technology is being adopted at a rapid rate and there’s no doubt it’s only a matter of time before every house with solar power has some sort of solar battery installed. 

Solar Battery Growth

According to a solar energy report quoted in the Herald Sun, around 7,000 solar battery system were sold and installed across Australia in the first six months of the year, compared to 6,500 last year. Queensland leads the charge, with New South Wales and Victoria close behind. In a market that has already doubled in two years, there is still a way to go before we see solar batteries as ubiquitous in Aussie households, but things are heading in the right direction, and a lot faster than you may think!

Tesla Powerwall 2 Solar Battery Growth
Tesla Powerwall 2 – a catalyst for solar battery growth.

Volkswagen just announced they will spend $50b on energy storage battery technology for its new line of EV cars – there are whispers about the Tesla Powerwall 3 – what’s next for solar battery growth?

Solar Battery Comparisons

There are a lot of different options on the market right now – a bunch of people are still waiting until the technology ‘catches up’ but solar storage can already be quite affordable – with average costs between $4,000 and $13,000, depending on the size/brand you choose. The Herald Sun estimates that it will take approximately eight years for a solar panel + storage system to pay for itself – i.e. it’s not economically viable for everybody right now but depending on your individual circumstances it’s far from a pipe dream. With that said, prices are expected to drop by up to 30% over the next few years as production ramps up and advances in the technology are factored in. 

If you’re interested in doing some research about energy storage, we have a page about the Tesla Powerwall 2 and its alternatives and competitors – there are many options to choose from such as Fronius, BYD B-Box, Redflow, LG Chem, sonnenBatterie, Enphase, Eaton Nissan xStorage, and so on. Make sure you figure out exactly what you need (e.g. grid or off grid? If you’re on-grid do you want power in a blackout? How much power do you need)   and do your due diligence before committing to a system – and if you already have solar panels make sure the storage system and inverter will pair correctly – not all solar systems are created equal!
