Note that this also assumes that the conductor whips from the modules ARE ALSO double insulated if they're to be used with TL inverters. Some mods have 'em, some do not.

If one can position transition boxes close enough to the modules, you can use only the leads from the modules, avoiding the need to buy any PV wire. It is surprisingly easy to do. See: http://www.millersolar.com/MillerSolar/practices/PV_wiring/PV_Cable_wiring/_ PV_Cable_Wiring.html WM double-insulated wire has to be used from the module series string to the first enclosure and enclosed raceway where the transition to standard THHN/THWN wire can be made. marco
