[RE-wrenches] Enphase System Labeling

[William Miller]

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.
