Proud to have played a part in this historical moment.

Fossil fuels, which have powered the global economy for centuries, are under threat. And Australia has become ground zero in this global battle.

Another quality Tesla Powerwall 3 backwards compatibility install completed in the snowy high country near Canberra.

This site is part of an early pilot program trialling the upcoming firmware update that will allow existing Tesla Powerwall 2 owners to expand their battery capacity with Powerwall 3.

We now have 10 active pilot sites and the feedback has been very positive.

Got a Powerwall 2 and thinking about expanding? Reach out to see if your site is suitable.

Powerwall 3 + Expansion Unit. Where energy independence meets art.

Not all batteries are built for Canberra winters.

Anyone who has walked outside on a frosty Canberra morning knows cold weather matters.

Powerwall 3 has intelligent Heat Mode built in. It can warm individual battery cells so the system is ready to charge and discharge efficiently, even when the temperature drops.

It is similar thinking to how Tesla vehicles pre warm their battery before Supercharging. The battery prepares itself so it can perform properly.

That means your Powerwall is ready to capture solar from sunrise, with no buttons, no settings and no mucking around.

Smarter battery tech matters.

As a Tesla Premium Powerwall installer, we’re excited to help test backward compatibility between the Powerwall 3 and existing Powerwall 2 systems.

One North Canberra energy geek and long term customer already owned three Powerwall 2 units and jumped at the chance to add Powerwall 3 along with two expansion units. This brings their total storage capacity to over 80 kWh storage to participate in a VPP.

The wider rollout is looking promising.
