Tesla Solar Inverter – first looks!

After an unprecedented 2020, Tesla have been busy in the background and this week have announced the launch of a new solar inverter.

An inverter is an important part of any solar system – it’s used to convert DC power (generated by your solar panels) into AC power (i.e. usable for grid export or usage in the home). For Tesla to dip their toe in this end of the market shows an interesting insight into their overall strategy to help manage renewable energy as widely as possible. Their website has a bit of a spiel about the product:

“Tesla Solar Inverter completes the Tesla home solar system, converting DC power from solar to AC power for home consumption. Tesla’s renowned expertise in power electronics has been combined with robust safety features and a simple installation process to produce an outstanding solar inverter that is compatible with both Solar Roof and traditional solar panels. Once installed, homeowners use the Tesla app to manage their solar system and monitor energy consumption, resulting in a truly unique ecosystem experience.”

Can I buy the inverter in Australia?

You can’t actually view the Tesla Solar Inverter page on the official Australia Tesla website yet (it just 404‘s) – but according to their press release “(the inverter) completes the Tesla home solar system”. You can use the American link which will show you the (fairly utilitarian) details they are currently providing.

So you still can’t get this in Australia but we’ll keep you posted as soon as there’s any information. Tesla are very US focused so hopefully they bring the party to Australia sooner rather than later! And on that note, no news yet on the Tesla Powerwall 3 but we’re still waiting with bated breath. The site for the new inverter notes that it’s “built on Powerwall 2 technology for exceptional efficiency and reliability” so maybe we are a ways off yet?

Tesla Solar Inverter Specifications

The product 660mm high and 411mm wide. It’s available in two configurations, depending on how many solar panels you have on your roof – 3.8 kW and 7.8 kW.

The new inverter will be compatible with ‘standard’ solar panels as well as integrating seamlessly with the Tesla Solar Roof.

A warranty is available for the product and will be a strangely chosen 12.5 years. Haven’t seen a half year in a warranty in a while!

The product will also feature Wi-Fi, Ethernet and cellular connectivity with OTA (over the air) updates, and has been “designed to integrate with Tesla Powerwall and Tesla app”. Matching inverters, batteries and panels can be quite the mission if you’re looking to get the best result so it’s nice to see Tesla working hard to offer more of a ‘full stack’ approach to renewable energy (not just solar power either!).

Lastly, it has 4 MPPT (Maximum Power Point Tracking) controllers. Most inverters have two so it’ll be interesting to see what we’re in for with the Tesla Solar Home lineup!

Tesla in Townsville – Bohle Plains’ 4MW solar battery.

Tesla in Townsville – Solar giant Tesla will install a 4MW/8MWh solar battery in Townsville, North Queensland to help manage renewable energy within the community. The battery is expected to be operational by the end of 2019.

Tesla in Townsville – Bohle Plains’ 4MW solar battery.

A community-scale battery will be installed in Townsville to help store excess energy, provide backup power to the community, and assist in providing support to Ergon’s virtual power plant, which draws electricity or reduces load from customers Queensland wide. This helps shore up any supply issues to the National Energy Market (NEM), especially during peak times such as during a heatwave.

Publicly owned Yurika manage the plant and it’ll be fascinating to see some statistics as to how this Tesla Powerpack helps QLD – with the South Australian Tesla Battery at the Hornsdale Power Reserve saving $25m in its first year of operation, we expect the result to be similarly impressive.

“This is a small but significant addition to Queensland’s publicly-owned electricity system, a system which is delivering cheaper prices on average compared to other mainland states in the National Energy Market,” said Acting Energy Minister Mark Furner.

“Battery storage technology is the next stage in steady progress to enabling a renewable energy future and reaching our target of 50% renewable energy by 2030.”

“With around 20,000 residential rooftop solar systems in Townsville, battery storage technology will help ensure power quality and reliability in the local network.” he continued in quotes repeated in Clean Technica

Design work has already started on the battery and Tesla in Townsville is closer than you may think – the battery is scheduled to be fully operational in late 2019. Given that Townsville and its surrounding areas have seen a significant amount of investment in solar over the past few years, it’s going to be fantastic to have this battery to help stabilise the grid and provide cheaper power.

Battery Energy Storage System in Alice Springs

Battery Energy Storage System – Alice Springs is set to receive its first grid-scale battery as solar power in the Northern Territory heats up.

The $8.3M, 5MW/2.5MWh grid-scale battery storage facility in Alice Springs was announced last year and has been completed this week. It was built by New Zealand solar company Vector using LG grid-scale solar batteries.  

Government owned Territory Generation (The Northern Territory’s major electricity producer) have advised that they’re hoping this battery will facilitate greater uptake of solar in the NT:

“The Battery Energy Storage System is an important milestone in the Northern Territory’s transition to renewable energy and a critical piece of infrastructure to support the Northern Territory Government’s Roadmap to Renewables strategy,” Territory Generation Chief Executive Officer Tim Duignan said.

“Reliability and stability of the power system is a critical barrier in the uptake of renewable energy across Australia, and I am pleased that we are at the forefront of tackling this issue right here in Alice Springs,” he continued.

The BESS should have quite a big impact on base-load power as well, so let’s see how it fares during summer 2018/19. Previously a very conservative approach to local grid management (read more in RenewEconomy) means this battery should help quite a lot: with half an hour storage capability, and can supply 8MW for 6 seconds, or 7.5MW for 60 seconds – suitable for the moments everyone decides their air conditioners need to be turned on at the same time!  

Mr. Duignan also discussed the plans for Darwin solar in the future: “The cutting-edge technology in our Battery Energy Storage System will reinforce Alice Springs as the solar capital of Australia by enabling greater solar penetration whilst maintaining grid stability.”

We wrote about the Battery Energy Storage System (BESS) last June as it was unveiled in an attempt to compete with the other states, where the Northern Territory was lagging behind considerably (January 2017 PV output was 4,049MWh vs Queensland’s 126,629MWh). 

The Northern Territory is in a very unique position compared to its neighbour states – the state hosts a mere one percent of the total population but it represents approximately 15% of Australia’s land mass. However, installs are more expensive over there due to less competition and higher cyclone ratings required on solar panels. This dearth of Darwin solar is starting to change and there are a raft of high quality solar installers working hard in Darwin, Katherine, Alice Springs, and more. It’ll be interesting to see how quickly they can catch up to the other states. 

Darwin Solar Farms

There are plenty of farms and solar projects in various stages of completion in the Northern Territory and this is growing rapidly:

  • GPT Group have 1.25 MW at Casuarina Square shopping Centre
  • Darwin International Airport’s 4MW.
  • Epuron are working on a 25MW Solar plant at Katherine.
  • The Australian Defence Force have tendered for a 12MW of solar (combined) at their Darwin and Robertson Barracks.
  • Rim Fire Energy Retail’s 10MW Batchelor solar farm.
  • Infigen Energy are building a 12MW solar farm at Manton Dam and 10MW at Batchelor.
  • Community solar project “Repower Alice Springs” is planning for a 10MW community solar farm.

Ballarat Energy Storage System | Solar Storage in Victoria

The Ballarat Energy Storage System has been turned on by the Victorian Government today – let’s take a look at this unique battery and see how it will help shape Victoria’s energy future!

Ballarat Energy Storage System

The Ballarat Energy Storage System has 30MW capacity and can output 30MWh – it’s located at the Ballarat terminal station and is owned by Australian energy company Ausnet. The battery storage units are Fluence branded, and were installed by Spotless and Downer Group.

ARENA and the Victorian Government will jointly provide $25 million in funding for both this project and the Gannawarra Energy Storage System (GESS). The project (BESS) is expected to end up costing around $35m. 

Lily D’Ambrosio, the minister for Energy, Environment and Climate Change, made a statement about the Ballarat Energy Storage System discussing the Government’s plans for Australia’s renewable energy future:

“We said we would deliver these large-scale batteries for Victoria, and that’s exactly what we’ve done,” she said.

“This is part of our plan to transition to a more affordable, reliable and clean energy system. We’re modernising our electricity grid, strengthening our energy security and delivering real action on climate change.”

According to RenewEconomy, the battery will be most useful in these three situations:

  1. It can help with congestion on Victoria’s transmission grid (especially as it’s installed at a network terminal rather than a wind or solar farm (which is the norm)). 
  2. It’ll help shore up the baseline load for Melbourne, especially during peak times when air conditioners and deconstructed latte machines are switched on en masse; and
  3. It’ll provide ‘key grid stability services’ like frequency control. 

Lastly, straight from the horses’s mouth:

The battery will store energy at times of relatively low value. The battery will use stored energy and use it at times of relatively high value. The project will also examine providing other grid services such as frequency control ancillary services (FCAS) and, should it be established under the electricity market rules, a Fast Frequency Response (FFR).

It’ll be fascinating to see how this works over the summer – we’ll, of course, also be keeping a close eye on the Tesla batteries at the Hornsdale Power Reserve to see if they’re able to continue delivering massive savings to the SA government. How long until the rest of the states follow suit?

“Delivering high-quality energy solutions for homeowners is a top priority for us,” said Markus Lambert, General Manager Solar & Energy for LG Electronics Australia discussed what adding a residential ESS (Energy Storage Solution) will mean for the LG solar brand:
 
“The addition of the ESS to our energy portfolio will enable us to support Australian homeowners with a 3 phase electric power and their demand for greater control over their residential energy consumption.”
 
The LG ESS battery and inverter is also modular – it can store up to 12.8kWh by installing the 6.4kWh battery packs. All of the devices are covered by a 10 year Australian product warranty. 
 
In addition to the ESS, LG Electronics also introduced their 2019 range of NeON®R and NeON®2 premium solar panels, which will have a performance upgrade to 370W and 380W as well as a 400W 72 cell panel. All NeON solar panels have a 25 year warranty. To be frank, these panels are quite expensive, but if space is a premium and/or you want to get the best result possible, they are highly recommended. Mr Lambert discussed the benefits of the new panels:
 
“Residential dwellings are constantly evolving, just like homeowners’ energy needs,” he said.
 
“These higher efficiency panels will benefit homeowners with limited roof space, as well as those looking to deploy energy-intense technologies, like electric vehicle charging stations.”
