[RE-wrenches] PV Production Meter on a XW System

[Kent Osterberg]

Aaron,

Is the objective to measure all of the energy produced or only that 
which is delivered to the grid? To measure the energy sold to the grid, 
the meter goes between the XW and the grid, but it must be an 
electronically detented meter that only records energy flow in one 
direction.
