Tesla Powerwall on external wall

Tesla Powerwall 2 Launch

Tesla has just launched the Powerwall 2 solar battery.  This 13.5kWh battery is changing the way we think about solar power.  Enjoy a family evening powered by the sun and watch your electricity bill drop.  The Powerwall can be connected to an existing solar system or to a new solar inverter and panels.  It puts you in control of when you use your solar power, including at peak times.  You can monitor the system through the Tesla app.  Solarpro will be installing the first Powerwall 2 on the Northern Beaches next week.  For further information and a quote.  Contact Us.

What you get with Powerwall 2

Solar Battery

Twice the size of Powerwall 1, with a capacity of 13.5kWh, this is one of the largest home storage batteries available. Powerwall 2 has a liquid thermal control system that regulates its internal temperature to maximise battery performance in any climate. It stores excess solar power to be used in the evening when electricity prices are higher.

Internal Battery Inverter

Powerwall 2 has a built-in battery inverter.  However, unless you connect it to an existing solar system you will have to purchase a solar inverter and panels in additional to the battery.  Solarpro recommends the SolarEdge optimised solar system.  If you prefer a string system, Fronius is a good choice and we can optimise the solar panels for you by adding some simple technology. Optimised panels operate independently rather than in a string and can deliver up to 25% more solar power.

 Power Back-up

There are two versions of Powerwall 2 available.  One has a backup facility to provide power to selected appliances in the event of a power black-out.  The other does not have a backup facility.  If you want the backup or think you might in the future, it is important to choose that system.  The one without backup cannot have it added later.


Tesla has already launched a new version of the My Tesla website & mobile app which includes solar system monitoring and Powerwall 2 integration.  The app has a Power Flow screen which shows real-time data on solar power generation, storage and consumption.

We look forward to discussing your solar storage options with you.  Give us a call or click here to get a Quote.
