About the installation.
This townhouse can store up to 27kWh of electricity, twice what one Powerwall 3 holds.
We fitted:
- 12 all-black solar panels, giving a 5.82kWp array
- a Tesla Powerwall 3, with its solar inverter built in
- a Powerwall 3 Expansion Pack, which doubles the storage
Both units sit on the front wall. Because the inverter is built into the Powerwall 3, the home did not need a separate one.
