City Electric Code
One surprise we got last week was the requirement to install an emergency disconnect for the Photovoltaic system that the utility company cold disconnect without entering the house. To accomplish this, they had to drill a hole in the dome wall, install a flex tube, remove 2 or 3 rocks, and soon mount an external box to allow the battery pile to be disconnected from the system. Just watch out for unusual city codes and make sure everyone knows what needs to be done. This was not an expensive almost mistake, but it could have been.
One bright spot that came from this si the realization that since we have a penetration through the house right there, we could also install a plug that connected directly to the inverter to allow us to connect a generator from the outside of the house. Thus if things get really bad, we can run the gasoline (or whatever) generator on the patio, and not have to worry about running wires through the doorway or whatever.
