Electrical wiring is nearly complete. Three electrical panels are installed in the yard equipment room. Why three boxes? The left two comprise the 400-amp service from the power company, and the third ("secondary," later renamed "solar") one is intended for a future solar power system. All circuits in this box will be fed from a battery-powered inverter that will keep these circuits live if grid power fails. Initially the batteries will be charged from the grid, but ultimately solar panels will charge them. Here is a block diagram of the electrical system (PDF opens in a new browser window; close it to come back here).


A river of cables connect the boxes to the rest of the house.
