Peter,
California utilities use to require operating steps (list not UL listing)
for all grid-tied systems in the interconnection application. A copy of the
operating steps from the equipment manual sufficed.

Subject: [RE-wrenches] UL and Grid-tied Battery Back Up Systems
Are there UL testing procedures for Grid-tied Battery Backup Systems, such
as the Xantrex XW systems and the Outback GVFX systems? The reason for my
inquiry is that the Los Angeles Department of Water and Power intends to
require that "...applicants installing Battery Backups on their solar
systems to submit an Operational Listing detailing a precise list of steps
of what were to happen if the LADWP grid were to lose power."
