Designing around the trees

Gum trees move shade across the roof through the day and through the year, so we placed the panels for what the trees do in July. The corrugated metal roof is straightforward to fix to and to seal.

The battery keeps the lights, the fridge and the pump running through an outage.

A Powerwall 3, an Expansion Pack and the gateway

A Tesla Powerwall 3 and a Powerwall 3 Expansion Pack sit on a concrete blade wall outside, with the gateway beside them and the isolators labelled ES and PV AC. The Expansion Pack is storage alone, with no inverter and no gateway of its own, so it adds 13.5 kWh behind the Powerwall it hangs off. Outdoors suits a wall like this one. The units are rated for it, the wall is masonry, and the run back to the switchboard stays short.

The gateway sits beside them and handles the changeover. When the grid goes down it disconnects from the network and keeps the home running on stored power, with no switch to throw.

How the Powerwall 3 works
