Grid-Tie Stumper (for me) [RE-wrenches]

Some of the electronic KWH meters only count when a hole in the rotating 
disk passes by a sensor - it does not know (or care about)the direction 
the power is flowing.  There also are some add on data logging systems 
for KWH meters which use this method as well. 

I also have wondered what this type of meters would do if it happened to 
stop in just the right position and a pair of SW inverter/charger are 
doing their "jitter bug" routine when they are trying to float the 
battery but not sell back current. Could be interesting...
