1 & 3 / 2 & 4 Tesla Inverter (top) and Powerwall Battery Storage (below it). Stores the power from the solar shingles.
5 Inverter. The shingles on the roof produce more output than the two Powerwalls can process, so an additional inverter was required.
6 Gateway. Connects and communicates between the Powerwall systems, solar shingles and the grid. It’s the brains behind the battery control system.
7 Junction box to separate wiring from the roof to each inverter.
