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 – 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 2019 announcement. Potential 2020 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.”

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.

Shell buys Sonnen | Cheaper Solar Batteries?

Shell buys sonnen: German solar battery company Sonnen has been bought out by global giant Shell for an undisclosed sum. The purchase is still subject to regulatory approval but let’s take a look at what we can expect from this situation.

Shell buys Sonnen

Shell Buys sonnen – sonnenProtect 1300/2500 (source: sonnen.com)

Mark Gainsborough, executive vice-president of Shell New Energies, discussed the purchase: “Sonnen is one of the global leaders in smart, distributed energy storage systems,” he said.

“Full ownership of Sonnen will allow us to offer more choice to customers seeking reliable, affordable and cleaner energy.”

Shell New Energies was founded in 2016 to ‘advance the company’s interests in electricity, as well as biofuel and hydrogen’.

According to the ABC, sonnen’s new location in Adelaide will reap benefits: the local workforce is expected to expand by 430 jobs this year. This is part of sonnen’s plan to build 50,000 battery systems over the next five years.

sonnen CEO Christoph Ostermann said the investment will help the company scale faster and will also have a greater good in terms of energy tech:

“Shell will help drive the growth of Sonnen to a new level and help speed up the transformation of the energy system,” he said.

Ars Technica are reporting that the company have over 40,000 batteries installed worldwide – in Germany, the US, Australia, and more. 

Shell last week confirmed they will extend New Energies into the Australian domestic market – which includes the construction of a 120MW solar project in Queensland – so this is a great step forward for him.

GAF Energy to sell residential solar.

Standard Industries has announced it will launch a rooftop solar company named GAF Energy in the US – they are already the world’s largest roofing and waterproofing manufacturer.

GAF Energy Rooftop Solar

As per a post on the Standard Industries website, the new company, GAF Energy, will work together with GAF to offer their DecoTech® solar roofing solution to “everyday consumers”

It’s an interesting niche to walk into – GAF’s new product offering has some competitors in the PV integrated roof tiling space, such as the Tesla Solar Roof, Tractile Solar Roof Tiles, Monier Solartileor Sonnen/Bristile’s Solartile  These are all fantastic products but fairly expensive at this point in time – hopefully having more competition in the market leads to more competitive prices and more powerful roofs.

“GAF Energy capitalizes on the historic challenges facing the rooftop solar industry – acquisition and installation costs – and turns them into demonstrable strengths – making it easy for customers to say ‘yes’ to solar rooftops,” said Martin DeBono, President of GAF Energy. “Our product is smart, integrated and economical, and we hope it will mark a fundamental shift in rooftop solar adoption around the world.”

Rooftop solar in America is a lot less developed than in Australia – according to Renew Economy, only 3% of USA homes had solar panels installed in 2017 – in stark comparison to Australia’s 30%. As such there’s plenty of opportunity if the product and price is right, and the governments get on board to help. Will integrated solar roof tiles be the way forwards in the future for domestic solar? We’ll soon find out. In any case, it’s exciting to see 

For more information about GAF, visit www.gaf.energy. If you’d like to read the press release about launch of the company and new DecoTech solar roof, please click here

It shouldn’t be long before we have some more information about how these solar roofs are performing, and as the results trickle in we will be creating a solar roof tile comparison document for anyone interested in integrating solar panels into their roof. Please watch this space! Exciting days ahead for rooftop solar.

sonnenProtect 1300/2500 blackout protection

A big week for German battery manufacturing company sonnen who have announced the sonnenBatterie Protect 1300 – also known as the sonnenProtect. This smart device links with an existing sonnen solar battery and detects mains power outages – at which point it quickly and safely switches you across to use your battery storage for selected appliances. They also have the sonnenProtect 2500, which comes with 2.5kW of power output as opposed to the 1.3kW the 1300 offers. 

A common misconception about solar+storage is that you’ll have power during a blackout. Without something like the sonnen Protect this isn’t the case. 

sonnenProtect aka Sonnen Protect 2500

sonnenProtect 1300, 2500 – Sonnen Protect

The sonnen Protect is installed close to the battery system and offers up to 1.3kW of power output (i.e. you can’t run a bunch of air conditioners off it but it’ll keep a modern fridge up and keep your lights on, run a laptop, charge your phone, run fans, etc.). It will give you a single protected power point – from here, depending on your budget, you can use extension cords and plug boards through your house, run cables to defined backup power points, or even run new cables in your walls to defined power points. Keep in mind that with the current option each power point will be limited to 2.5kW load or 1.3kW with the sonnen 1300.

The device can be retrofitted to all existing sonneBatterie Eco models, which are modular and start at just 2kWh up to 16kWh in the same cabinet. You can chain multiple cabinets together if you need more than that. 

sonnen made the news last year with their ‘free power’ offering via the sonnenFlat service, so this is another great offering from a renewable energy giant (they are the world’s largest home storage battery company)

Sonnen Protect Specifications, Size, Price

  • 15cm wide
  • 19cm high
  • 12cm deep
  • 800grams

Depending on what sort of solution you’d like (with regards to power points and running new wires in the walls), the install for a sonnenProtect 2500 is generally under $1,000 AUD.

If you’re interested in the sonnenProtect for your house please shoot us an email at [email protected] or fill out the form to your right and we’ll be in touch.

sonnen in South Australia – HQ, manufacturing plant.

sonnen in South Australia – the German battery manufacturing giant (which is also the world’s largest home storage energy company) have announced that they’re going to move their Australian headquarters from Sydney to Adelaide. The announcement was made last week during a huge week for renewables in SA – with the upcoming election both major parties have promised $100m in solar loans for South Australian residents.  

sonnen in South Australia

Along with the administrative tasks (i.e. the ‘headquarters’) of sonnen’s Australian operations, they’ll also be setting up a full energy storage manufacturing facility in the state.

Chris Parratt, the Australian boss of sonnen’s Australasian business, said the company will have a solar battery manufacturing facility ‘up and running’ in Adelaide within six to nine months.  According to the Australian Financial Review, Parratt says the facility will be able to produce 10,000 systems a year, including sonnen’s flagship sonnenBatterie line. He noted that they are looking at four separate locations in Adelaide, including the former Holden car manufacturing site and the former Mitsubishi car-making factory in Tonsley Park precinct.

Parratt noted that sonnen have set up a similar facility in Atlanta in the United States of America in a fast timeline last year telling a press conference (along with South Australian Premier Jay Weatherill) that they’re confident in scope management:

“We believe in about six to nine months we’ll be producing our first energy storage system,” he said. 

sonnen already have 30,000 household batteries installed in Germany, making them the world’s largest home storage energy company. 

It looks like this will go ahead regardless of whether Weatherill’s incumbent party or the South Australian Liberal leader Steven Marshall wrests control of the state – the latter is against renewable energy targets but has also committed to a $100m means-tested subsidy for up to 40,000 households to get interest free solar loans. 

Weatherill was quick to extol the employment ramifications of the move, having been told he was “doubling down to chase his losses” by federal energy minister Josh Frydenberg last week with regards to raising the RET from 50% to 75%:

“We saw yesterday I was accused of being a problem gambler. Well today, South Australia has hit the jobs jackpot,” Mr Weatherill said, referring to Sonnen’s plans, which will create 130 new immediate jobs, rising to 190 by the end of the year, and then another 300 jobs for trades people to install the batteries.

It’s shaping up to be a very interesting election in South Australia. Who are you voting for, and why? Let us know in the comments.
