Tesla Powerwall 2: The Ultimate 2022 Australian Buyers Guide

Tesla Dimensions

Tesla Powerwall is a smart home battery system that integrates with your existing solar system and can provide backup power for when the grid goes down. In Australia, solar batteries have completely revolutionised the way households use, store and manage their power, now making it possible to run your household on solar power 24 hours a day.

The Tesla Powerwall 2 was introduced into the Australian market back in 2017 and came with a number of improvements over the first iteration. It has over double the storage capacity, includes an integrated battery inverter-charger and the Tesla app, performs better in a range of temperatures and is easier to install.

Tesla Powerwall enables solar households to further reduce their power bill and maximise solar self consumption. In fact, with a capacity of 13.5 kWh, a typical family home will be able to run all evening on stored solar power.

Solaray has led the charge with Tesla’s rollout of one of the most exciting solar batteries to hit the market, becoming one of the largest installers in Australia, installing the Tesla Powerwall in both Greater Sydney and Melbourne.

This experience gives our customers the peace of mind that their installation is backed up with responsive technical support and customer service.

What Is The Benefit Of Installing Solar Batteries?

Performance and Mechanical Specifications Summary

Tesla Powerwall 2 is a fully-integrated AC battery system for residential or commercial use. This means it’s easily retrofitted to any home or building with an existing solar system, or can even be installed without solar and used solely for backup power purposes.

A clever hack taken advantage of by those who buy a Powerwall without solar is charging it during off-peak daylight hours and discharging during peak hours at night.

Tesla Powerwall Installation

The Tesla home battery weighs 114kg and can be mounted on the ground or a wall in the installation process. However, in compliance with Australian regulations, the Tesla Powerwall 2 installation must be done in a non-liable area of the home. This means installation is limited to enclosed or sheltered garages, or outdoors on the side of your house.

The IP56 weather rating allows Tesla Powerwall to operate efficiently in a broad range of temperatures, providing a steady stream of power from outdoor installation. The liquid cooling and rated operating temperatures ranging from -20 to 50 degrees allow for this. Keep in mind that, as with any electrical device, reduced output may be experienced at the extreme ends of the temperature scale.

Tesla Powerwall Review

The Tesla Powerwall Home Battery was introduced to Australia back in 2017 and has been increasingly popular as the solar battery of choice in Australia. It has a storage capacity of 13.5 kWh which can power your home overnight until it is recharged by the sun again.

The Tesla Powerwall 2 also has a 5kW continuous output with a peak of 7kW, which is double the amount from the previous model. But what does that mean for your household? The increased output and capacity means that it can keep your household powered for longer, which results in lower energy bills from the grid.

With a rated operated temperature range of –20 to 50 degrees, the Tesla Powerwall 2 operates more efficiently within a broad range of temperatures. This is thanks to its unique liquid cooling system which makes it superior to other battery systems in the market.

The Tesla Powerwall Home Battery offers three energy consumption modes: Back-Up Only, Self-Powered, and Time-Based Control.

  • Back-Up Only: Aims to keep the battery full so in the event of a power outage you have maximised protection with continuous power in a blackout.
  • Self-Powered: The most common purpose and mode to having solar power, this aims use as much solar energy generated from your panels thereby reducing your carbon footprint and electricity bills.
  • Time-Based Control: Aims to reduce your costs by allowing you to charge and discharge at certain times of the day depending on the peak and off-peak energy rates.

 

Monitor and Manage Energy Consumption With the Tesla Mobile App

Tesla has developed an app that is considered to be one of the best and most innovative energy management software systems, known simply as the Tesla Mobile App. Supported on both Apple iOS and Android, the Tesla app allows users to monitor real-time home energy consumption, solar system monitoring and Powerwall Battery energy management.

For Tesla electric vehicle drivers, this utilises the energy component of the same app that is used to monitor their car and gives an added level of control when charging vehicles from the solar or Powerwall.

Tesla Energy App

Tesla Powerwall Optimised By Evergen

All Tesla Powerwall systems installed by Solaray are optimised by Evergen. Evergen Intelligent Control Software optimises your solar & storage system to save you an additional 26.4%* on average on your power bills.

Evergen can further reduce your power bill using an advanced algorithm that includes 42 different data points:

Weather Forecast: Evergen predicts your solar output to ensure your battery is adequately charged during wet weather.

Your usage patterns: Over time Evergen uses machine learning to predict how much power you use, and when. For example, if you need more power on certain evenings, Evergen will make sure your battery is fully charged for when you need it.

Tariff Awareness: If you are on time-of-use tariffs, Evergen will make sure you use as little grid power as possible during the peak billing period. It can even charge your battery overnight during the off-peak tariff if you need it or if wet weather is forecast for the coming days.

System Health: You no longer need to worry about the performance of your system. Evergen not only keeps track of system performance, it actively works to maximise the performance and longevity of your battery.

Intelligence data is also available through the app such as how much money you are saving and your solar generation. Daily monitoring by Evergen helps you to:

  • Save even more from your solar generation
  • Store and resell excess energy generated by your solar panels
  • Use your solar energy even when the sun goes down

Living Without Power Bills – Angela’s Story

Powering the home used to cost her $2400, but in the months after combining her solar panels with a new Tesla Powerwall home battery, her power bill has dropped to below $0. This means her power retailer is, in fact, giving her a credit every quarter for the energy she’s contributed back to the grid.

“My power bill used to be $600 per quarter, the last bill I got was a credit of $40. I’m sure the next bill will be even better since it’s summer.”

Angela’s Tesla Powerwall was installed at a good time, since power prices have continued to rise to record levels.

The even more remarkable fact is that Angela managed to reduce her power bill without cutting down on her electricity usage. In her living room when we talked to her, there was an air conditioner running and the standard home appliances were all running.

“Today, I did 2 dryer sessions and 3 washing sessions. I don’t skimp at all.”

Many Solaray Customers No Longer Pay Power Bills

We now have customers like Peter running their home on solar power 24/7, and paying quarterly power bills well under $100 a quarter:

“I am pleased to be able to say that the system has worked flawlessly since commissioning and has exceeded my expectations.

Our last monthly bill was $10.53 – the same bill in previous years was $198.79 and $163.67″

How Solar Storage Reduces Your Power Bills

The feed-in tariff for selling excess solar power back to the grid is very low in many states of Australia. In Australia, we typically get a credit on our power bill of between around 10 and 12 cents a kWh. By storing this excess solar power in batteries, we can use it during the peak billing period where prices can be over 50 cents a kWh. This is known as maximising self-consumption of solar power and is a great way to reduce your power bill. Many Solaray customers are now running their home almost entirely on solar power!

Energy prices continue to rise

Solaray Energy Tesla Powerwall 2 SolarEdge Installation Professional

Even if you get a discount from your energy retailer, power prices in Australia are amounts the highest in the developed world, in some cases more than double the price for energy compared to nations such as Sweden and Finland. Nationally, prices are up more than 120% over the last 10 years, and this trend is expected to continue for the foreseeable future. By installing solar with battery storage you can lock in your power prices for decades by generating most of your own power using solar.

Australia is still mainly powered by coal & gas

Australian households are leading the world with our uptake of residential solar power with millions of solar systems installed. Even so, there is still a lot of work to do. Most of the power generated in Australia still comes from coal, and there is reluctance in Canberra to transition to renewables. The biggest vote we have as consumers is to lead the way by installing solar power with backup storage. It’s by far the biggest single action we can take to reduce our carbon footprint. By installing a 10kW system, we take around $100,000 off the books of the coal industry and directly invest in growing the renewables industry.

Solar storage systems include revolutionary energy management technology that automatically directs solar power into your home or to recharge your batteries. Online consumption monitoring allows you to monitor how much power you are using in the home as well as how much solar power your system is generating.

Exciting home automation is on the way, which will allow you to send excess solar power into appliances such as automatically turning on the pool pumps, air conditioner or underfloor heating. All of this will be able to be controlled from a mobile phone, allowing you to take back control of your power consumption.

EV charging is around the corner. Installing a solar power system will allow you to charge your electric car from excess solar power, and it may even allow you to charge your home batteries from excess capacity in the car’s battery.

The power grid is struggling to generate enough capacity on hot days, causing highly-publicised and disruptive blackouts in SA and around Australia. By installing solar storage, you can continue to run essential appliances in a blackout such as your freezer, the internet and perhaps a few lights.
