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...
