  • Your Tesla Powerwall Solution

Say hello to the Tesla Powerwall 2 –

The next evolution in home energy storage is here! Tesla Powerwall 2, Tesla’s newest solar battery, has hit the market with installs scheduled to begin in early Q2 2017.

What makes this solar battery so significant?  The Tesla Powerwall 2 battery has an incredible 14kWh of battery storage, double that of the ground-breaking original Tesla Powerwall, in a smaller unit!

The second generation of Tesla Powerwall, ‘Powerwall 2’, is a battery primarily designed to store power generated from solar panels. When it’s needed Powerwall 2 will feed the stored energy into your home, so it’s perfect for night-time, power blackouts or even when it’s cloudy and your solar system is not performing to maximum capacity.

Powerwall 2 – supports:

  • Maximised solar self-consumption
  • Time of use load shifting
  • Back-up power functionality
  • Employment in ‘Off-Grid’ Solutions

Boasting a generous 10 year warranty, the Powerwall 2 has been designed and the warranty set out for the battery to be cycled daily (the process of charging and discharging) and with its generous 14kWh of battery storage has enough energy storage capacity to power a typical family home* with a little left over.  Homeowners can virtually go off-grid, paying mere peanuts to their energy retailers for the little power, if any, which might be required.  With a single Powerwall 2, you could power a typical two bedroom home for the entire day*, free from grid power, utilising only your solar system and Powerwall 2.

The Powerwall 2 is available as an ‘AC-coupled unit’ with its own battery inverter.

What this means for homes without solar – You don’t need to purchase an expensive hybrid solar and battery inverter.  You are able to choose any inverter you like.  Power optimisers, micro inverters, standard inverters, an (we sell them all too!).

What this means for homes with existing solar – You don’t need to throw out your existing inverter and have it replaced to take advantage of this Tesla battery. Even better, you can add additional solar at any time and this will still be able to flow into the Powerwall 2 before any energy is exported to the grid.

It’s also sleek, compact and stackable (up to 9 units), can be floor or wall mounted, indoors or outdoors. Finally, Powerwall 2 can be added to an existing solar system as a ‘retrofit’ unit or as part of a brand new solar system and battery combination; ask us today about ordering yours or view more details here

*Based on data from the Australian Bureau of statistics, 2014. Avg National household uses 5,817kWh per year. Using trend of energy use reduction of 12.5% per year, average daily use in 2016 is 12kWh per day.

The Tesla Powerwall 2 is the most affordable home battery in terms of cost per kWh.  Powerwall 2 economically meets the daily needs of the average family household.

Powerwall 2 has a long life due to its liquid thermal control system regulating Powerwall’s internal temperature to maximise battery performance in even the harshest Australian climates.

To top it off, Powerwall 2 also has in integrated internal inverter to convert DC energy to AC energy which is what your household runs on, which lowers the cost of installation and complexity of installation.



What makes Tesla Powerwall the ideal battery storage for your Australian home?

Australia has one of the highest electricity prices in the world, and it’s increasing at a steady pace too.  We have an abundance of sunshine too, which makes the Tesla Powerwall 2 a no brainer for both homes and small businesses.

The Tesla Powerwall is built with Australia in mind to combat this.  It meets and exceeds all safety requirements for Australian lithium-ion solar power batteries, meaning it can be installed anywhere across Australia.

The 13.2kWh Tesla Powerwall is specifically designed with the average Australian household or small business in mind, with the specific intended use and the ideal chemical lithium-ion composition for the Powerwall to be charged and discharged (cycled) on a daily basis.
