Here in Xcel territory in Colorado, we are required to cold-sequence the solar production meter. These disconnects have to be utility accessible and adjacent to the production meter itself. I believe this is only a utility requirement, not a code requirement. This seems to be unneeded redundancy, because the inverter side will shut down, once the line side is deenergized.
