Kent:
Good points. Enphase may allow us to disconnect their DC connectors under
load, but each of their connectors mates with a connector installed at the
PV factory. The module makers usually say don't disconnect under load. So
the inverter and the PV listings both need to allow disconnecting.

Marv,
The manual now clearly states that the ac and dc connectors have been
evaluated and approved for use as the required ac load break
disconnect. Yet in other locations the manual still says "Never
disconnect the DC wire connectors under load" and "The AC connector of the
first microinverter in a branch circuit is suitable as a disconnecting
means once the AC branch circuit breaker in the load center has been opened."
Sorry, but that's just not a clear a set of instructions yet. Can we open
these connectors under load or are we never supposed to open them under load?
